Thought you guys may be amused
Now that looks interesting Lee, ia that an audi V8 trying to mate with a VW polo.
Looks like you like working things out in very tight enclosures
V8 in a Polo, NOW were talkin! ;D Good work, will sound even better.
Yep--
4.2 litre mated to a vr6 box .
Have worked it to be lighter on the front than the 1.8t with all its pumbing.
And yes its tight--
As a daily driver it should be ok
you are a Nut Bar! :o >:D
8) 8) 8)
Surely cant be much lighter.
Nice job, if it all can cramp in there
Awesome - I love it :o. A V8 Polo - possibly a world first?
At first i thought Lee was just taking the piss, but now i realise he is serious, and knowing quiet Lee, he will have done lots of research before posting this up.
His technical ability is realy good.
Looking forward to seeing this thing being born.
Keep us all posted
Thanks Noel,
Yes it's an interesting project.
Just for your info--the 1.8t conversion was good and I used it for 40 000 k
But you know how the incurable swapper mind works----------------hopeless
Anyway
The weight of the turbo engine + all gearbox etc etc =209 kg
The weight of the v8 is about the same but alittle tighter.
The battery and brake booster and windscreen water bottle is all going to the rear.
I hope it will be better mannered than the 1.8t
Will keep you posted
This is awesome Lee, best of luck with the project!
Do you have a time frame you are working to?
Madness, what ecu are you going to use? How much hp/tq do you think you will get?
is it even going to fit behind the grill, let alone under the bonnet?
or will you have an even bigger hole than the twin VR6 Lupo?
crazy enough to be worth trying though, ::)
Hi Guys
In answer to the questions--
Will be using the same Link computer that ran the 1.8t
If anything it will be alot simpler
Re the size--No I don't like to show externally any difference than a standard car.
So no bulges --Its just a matter of modifying things until they fit.
Interesting that the motor and box fits sideways but is very wide--so it almost touches the firewall and the radiator,--this conversion would be easy in a golf or a3--
I don't know why others haven't tried it
Cheers
The polo is an interesting cheap car, i have often toyed with the idea of fitting a V8 FWD assy in the rear .
But this has to be much more of a challenge, the alternator and PS pump will have to be really tight.
Anyway, good luck with this Lee.
Cheers Noel
What the hell Lee!
One large serving of torque steer coming right up!
Um what are you doing with the engine mounts from the 1.8T - > polo???(I take it this was the 1.8t polo?)
Ill be passing through tues night or wens morning so WILL stop in this time.
Sounds like the ultimate Q car if you can get the power on the ground.
I'll be keeping an eye on this thread for more updates
What do you mean better mannered than the 1.8t?
Any updates Lee?
Disbelieving Poms, and a little negative ;D

I must say i like what your doing there
I have often thought i should get a Shell of a Skoda Fabia with the front taken off and gutted then get my Engine Lift and Suspend a V10 TDI there and pretend im going to retro fit it
and just take a Photo of it just to show how wonderful my digi cam is :) i love modern Tech :)

:angel:
I look forward to progress on this project, but i think Lee will keep any progress close to his chest.
Do you know me so well Noel--
Apart from making 3 adaptor plates to get the output flanges on the gearbox in the right place--!---
Yes it's work in progress
holy cow!! wow this is going to be great.
Rear engined would be cool, but ruin the stock sleeper look.
Maybe after you have finished this in 40k you could always rear mount it for a change ;D
Hi Lee, has using the offset bellhousing on the VR6 gearbox helped or would it be easier to use a 4 cylinder straight up housing. You could always swap to a 4 cylinder housing if you intend to fit a LSD
I sneaked over to Cambridge on Tuesday to look at Lee's progress.
It is certainly a complex job, but lee is making a great job.
His attention to detail is truly amazing, i also bet Lee goes to bed thinking about little details every night.
I didn't take any photos, i will let lee show us when he is ready.
This car will look absolutely stock, no bulges any where, only problem at the moment is how to hold bonnet closed, as the catch which is in the middle front edge of bonnet is taken up by the cylinder head.
The radiator will be quite a compact assy, but amazingly the alternator and power steering pump fit easily, i cant say that about other bits though.
Truly amazing job Lee, well done.
Looking forward to seeing any updates. Some low profile bonnet "pins" (e.g. http://www.aerocatch.com/?gclid=CJKd0IDc05sCFRUwpAodz0DVKg (http://www.aerocatch.com/?gclid=CJKd0IDc05sCFRUwpAodz0DVKg) might be the way to go but kind of give things away a bit as well.
gas struts to hold it closed, with a bonnet release on one side and safety catches both sides
The E36 BMW has a catch for either side, L & R at the front could you rework a similar system?
Any updates yet Lee?????????
Yes---
The engine is in---
Just sorting things phase now
Will post some pictures in a few days
I know just how it goes Lee, many days are spent amd nothing to show.
It must be quite exciting at the moment.
Looking forward to seeing the pics Lee :)
me three 8)
You guys are scareing Lee off with these comments about seeing pictures, mostly because he will be reluctant to just post up any random pix, he may end up almost finishing the conversion before he shows anything more, i know i would feel like that.
da da da ding ding ding ding ding............
Pics as requested.
Motor in !
Engine mounts top side
Thats so cool Lee, i know just how hard it is to feed these on Vask with photos. Good work.
Gearbox mount and below
What gearbox are you using Lee?
Quote from: Golfboy666GTI on July 21, 2009, 07:45:22 PM
What gearbox are you using Lee?
VR6 box Nik, that driver side CV looks really close to the side of the block, must have taken a long time to get orientation of engine and box right.
Great stuff.
This what was cut out of the passengers side front rail.
Because the car is just over 15 years old it does not have to be front impact compliant .
The rules are fairly stiff for later 95 cars onward.
My certifier here in the Waikato was quite happy with me cutting so much-- as the left rail only holds up the bumper it's not a major
Its tight on the right side but I didn't need to modify it
Front off and on
Because the back of the v8 almost touches the bulkhead -the brake servo had to go.
Shown is a Nissan 25 mm master cylinder with pipe work to the rear remote servo .
Only the front brakes will be assisted.
Work in progress
You have been busy Lee, it must be so tight around the firewall side if the exhaust manifold as well.
Did you sort out the bonnet catch probelm?
Has anyone heard of this type of transplant being done before or is Lee breaking new ground?
Breaking new ground
I would say he's breaking new ground, great to see someone doing something different.
Looks like it has come along very nicely from when I saw it last Lee, great stuff.
You can see from this the front bank of cylinders.
My overall concern with this exercise is how front heavy the car will be.
I have reduced weight as much as possible and even had to delete the inlet manifold as it weighed 15 kg
Will be making a light weight aluminium manifold with short tracks instead of the original variable castings.
This will probably reduce the torque but I don't think power will be a problem.
Am working on the exhaust -oil external filter-brake lines -remote servo -battery relocation---
yeah --still working
Where are you putting the radiator Lee? When I saw you last I don't think you had decided?
In front like normal.
It's slightly smaller than I would like and the fan may have to work more than normal.
With 4.2 litres it's not going to be under stress as the 1.8t was.
I have just had a major problem finding a crank angle sensor as the v8 ran it's sensor on the flexie plate. Ended up with a Nissan v8 sensor that I have to adapt to the end of the cam.
There are alot of things that will require modification but the main thing now is to get it running
That is awesome Lee. :o
This is brilliant!
Have you looked at dry sumping it to move some more weight?
Hmmmm interesting
I just weighed 4 litres of oil --about 3 kg--
Certainly worth investigation
Thanks
Any updates yet Lee?
If your car goes anything like mine, you will have a problem, at least can reduce boost........... >:D
Not much to report--
Just finished the exhaust extractors --working on the rear brake booster and the new inlet manifold.
Another couple of weeks it will go in for the computer to be set up.
You should feel what real power feels like Lee............. >:D
Pretty disgusting really. ;D
Any updates on this please?
I'm keen to see the finished product
Yes lots of progress--
Inlet manifold is now finished--weighs 3 instead of the 15 kg of the original
I made a battery box for the rear for both battery and remote servo
Brake lines are all in--just need to bleed them
All the pipe work and radiator is now in and leak free--
Remote oil filter in now mounted
Crank angle sensor I finally found from a Nissan v8 --and I had to make a special thingame to mount it on the end of one of the cams
Oh yes a complete set of extractors ---
They say the devil is in the detail---Endless
However it should be ready to go for the computer to be re set and dynoed maybe next week hmm maybe
Will get some photos up soon
So car is almost running, really great progress Lee, will be interesting to hear it too, A V8 Polo WOW.
That's some good progress.
Sweet, how cool is that!
Fantastic progress, did you solve the problem with securing the bonnet which by the sounds of it is a very minor detail compared to some of the other issues?
Hows it going? Made it to the dyno yet?
Yes--
The computer had to be sent to Link in ChCh--but all going well it should be running next week
Actuality until it runs I have no idea as to how everything will work--there is so many decisions and assumptions in its building that it's a large leap in faith--quite nerveracking after all the time and energy
Will post some pics later
Cheers

jesus, what the damn are those dudes up to? those links are crazy..... in a bad way...
any progress pics?
neat project!!!
That first clip is nearly onto it, mid-mount with RWD.
Thought I had better report in--
Well I got the car back from the computer wiring dept--with a few issues to modify.
Oil lines are too small for the oil flow required and several of the injectors needed cleaning.
But I started it this morning and ran it at idle .
Interesting its very very smooth and very quiet--quite suprising.
Should fix the oil lines next week --and then it can be driven at long last.
Also playing with 4 pot wilwoods to replace the standard front calipers--hope to delete another 10 kg from the front.
work still in progress---Will paste some pics next week
Great project Lee, looking forward to a ride in this beast.
Did you think this was going to be as much work, when you started it?
Oh, forgot, i have another job for you to do over our way, re grills.
Will ring soon.
Cheers
It's always more work than one thinks--
This week I have solved the oil supply problem and it's now ready to go back for final tuning --finally--
And it starts---getting closer to usability
A big lazy V8 in a Polo , should mean top gear starts ;D, what will happen when you get bored with torque Lee?
I hear its very contagious
You may be infected yourself--after you drive it
I don't have the torque of a V8 Lee, but i can spin the wheels in second gear, even with the Quaife box, so your car will definitely be a top gear start car ;D
Just a few pics
Certainly looks full in there!

Thats just soo cool Lee, that engine bay has a spot closer to the rh guard, surely you can fit something in there......... ;D
Bring the car over to Oto, sometime, or i can sneak away from work, anytime. >:D
The aircleaners not in there yet--
The car goes back to the Dyno Monday---
Looking at a carbon fibre bonnet to reduce more weight.
The willwoods are really light but the 280 disc is 5 kg--Still I will reduce about 14kg using this set up
and yes I will visit Oh oto
Still more work in progress
That engine bay looks really busy................
You will be able to fit into small spaces with that, but tow big boats.
That looks fantastic Lee, we will have to visit with the Vento to have a look at your beast.

with that power/torque to weight ratio, a rear mounted turbo sounds like a recipe for
lag
but like the Vento, driveability before boost should be tops
Got to have a look at the Super polo today :o Really amazing build to fit that in there!
And nicely done too.
And Lee has the biggest shed in vask! It's HUGE!
Looking forward to seeing this in action!
WOOW. I neva thought 1 would fit
Well I drove it today----
First impressions are as expected.
Yes it's front heavy but doesn't feel any worse than when the car had the 1.8t
It's very smooth and quiet and although it's not tuned properly it accelerates ok
A few issues of course;;
The clutch slave cyl is not disengaging properly so I have a problem
Does anyone know if the slave on the gearbox is different between the O2J box and the O2A VR6 box
Is it possible that the slave just doesn't have the travel to disengage
Would appreciate your advice
Apart from a few oil leaks and the winwood calipers hitting the rims under braking- all OK
Still work in progress
That's a great result for first time out, congrats Lee,
Interesting question Lee, just look at what you are using and what is different from factory.
You have Audi A8 engine, Vw Polo master cylinder and Vr6 gearbox, with Vr6 slave cylinder.
Your Audi A8 clutch has a clutch length, the VR6 has also a stroke, and the Polo master cylinder can push so much.
So which part is the miss match?
I personally doubt the slave cylinder is the problem, so the OEM Polo master cylinder is probably the problem.
With my car, i had a std Mk1 golf and a 02A gearbox, using a mechanical clutch assy.
I found that the stroke of the std Mk1 system stroked 80mm and the 02A gearbox is 50mm, so i used a reduction stroke ratio to overcome the problem.
So, i am guessing that the problem probably is with your clutch master cylinder assy.
I would second that if indeed you are using Polo clutch master.
No the polo has a mechanical clutch cable.
I used a hydraulic master off a golf 1.8t
It worked with the turbo motor and I haven't changed anything other than the Vr6 clutch
It worked with the dual mass clutch of the turbo
Just wondered if the gearbox's were different??
Quote from: Lee on December 11, 2009, 09:27:49 PM

Bit of a conflict here?
So you cant get it into gear? I would try a few starts with it in gear and foot on clutch. If it starts and isnt trying to drive forward to hard it may just be a bit of wearing in to do.
BB -You were right on the money!!
Did as you said and Yes it's good
Thanks!
Cars arunning!!
Still curing oil leaks and other teething problems but it drives OK
However because of the small size of the radiator due to space constraints,
I need to put on 2 more small cooling fans. Unfortunately the body work below the bumper doesn't give me enough room.
Jamie at Platinum tells me that the 1999 Polo has a one piece bumper/spoiler that may do the trick.
Does anyone have a secondhand one I can try?? Condition immaterial
Cheers
Try using water and water wetter only with no glycol.
Excuse my ignorance --never heard of of it--What is it?
Not being a dick or anything, but a google search would probably answer 90% of the questions asked on VASK ;)
http://www.google.co.nz/search?q=water+wetter&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-GB:official&client=firefox-a
Don't know what type of driving you have done so far Lee but once you can just sit in traffic on a hot day and it doesn't overheat thats when the cooling system is sorted.
I doubt water wetter will be the complete answer to your problem, bigger radiator and/or more cooling fans will be the ticket I'd say.
How about a larger tank? more coolant in the system will also help but a bigger rad will be the most effective.
At least you know water wetter will fit ;)
WOW! :o :o :o Thats Gunna be soo mean! ;D
Just a small update--
The cars going well and yes lots of torque steer
I just had the car weighed and was quite pleased with the out come of my weight saving efforts
Car as 1.8t--- 1020 kg with 670 kg on the front wheels
Car as 4.2 V8--1030 kg with 680 kg over the front wheels

around cambridge :D aparently he might be getting it back from dyno today!!
Yes well I finally got the car back from the Dyno --lots of problems
198.8 kW at the wheels---and dead flat torque of 550 Nm from 3 to 7 k
And yet it's very easy to drive
Next is certification
Cheers
Wow that torque is very impressive,also the power is great.
i doubt you will modify anymore.

What were your problems Lee?
The problems related to the combined Nissan crank angle and cam angle sensor running off the cam.
Link in CH CH had to modify the computer to stop misfiring.
The plugs were firing but not necessarily when they should have.
There was a possibility of destroying the motor--
So the shop had it for over a month and were pleased to see me take it away.
It's interesting that although the car has high power and light weight ,it's nothing spectacular.
Driving back to my workshop I was wondering how to give it some real power--yeah right

Great result - V8 power!
I am interested to see how the gearbox holds up to that torque, i suppose the grip will decide that.
Should be fine if he doesn't side step the clutch, may need slippery diff tho.
Very cool. bet it sounds awesome- can see it now, a little unasuming Polo with a V8 growl ;D
I just had a look through this ....and .......Wow-weeeeeeeee......that there people is a MAN_POLO.....Great stuff Lee! scare the crap out of people with that pocket rocket

Had the car out today..
In second with full power there is wheel spin but suprising very little torque steer.
Makes me wonder if someone installed a L/S diff in the box already.
Sounds of the engine under full power ---mmm interesting
It would be interesting to take your car for a drive Lee, it will be much dufferent from mine, but that torque level interests me.
I'll bring it down after it's certed--or if your passing sometime---call in
Whats nice is that the torque is instant.
Just passed certification
WOF when the cert plate comes---
Thanks to Andy--great help when I needed it
Great result Lee, whats next? ;D
Got WOF today and paid for the certification ---$540.00 including the WOF
Pretty happy with the cost to be able to drive it legally---
Lots of refinements now
this is awesome mate big respect.where abouts are you based would be good to have a browse over this.

You must be pleased so far Lee, must catch up some time.
Beware of posers
Cars going fine and just passed it's first WOF since the transplant.
I have a tech problem which I hope someone can help with.
The rev counter reads exactly double as there is 8 instead of 4 pulses
Link in CH CH say the computer I am using cannot supply 4 pulses.
Anyone know how to modify the rev counter to read correctly?

abit garry but could you put a aftermarket one in place of the standard one with abit of chop choping??
something like this?

Phase 2
Is that a blower Lee? >:D >:D
yes sprintex and 40 v
i knew you had a 40v V8, but a charger as well :), do you realise the facts about traction with your Polo. ;D
The engine currently in the car is the 32 v engine
This new one is 40v and 60 mm wider which means further surgery
And yes maybe between 4 to 500hp
But you know i don't drive fast
Some people collect stamps
Good on you lee :D
I hate stamps ;D
reminds me of the good ol' American saying "nothing exceeds like excess" ;D

Will be an a8 or a6 as its a belt driven 40v, the 40v from the b6 s4 is chain driven off the back of the head and is a realy compact engine
Yes it's a BFM A8 2006
The gearbox is for sale
Pictorial update
Inlet manifold is without it's top but you get the idea of the 4 Laminova intercooler cores.
The sprintex supercharger sits in the V under the manifold.
Just work in progress
This build is F****** ridiculous... Lee Awesome!!!!
Full credit to you and got to see some more pics
I love your maddness Lee.
yeehaaaw 8) 8) 8) 8) 8) 8) 8)
Hang on, Hang on
Let me get this right, youre supercharging a 4.2 V8.... Polo? :o
AWESOME! >:D
Good for burnouts?
I want one!!! :P
Feet on the ground guys---
These engines power mums picking up the kids---no drama
Supercharging maybe only 6 psi which will make it nice and torquey--
Still my daily road car---
People who have driven it with the old 32 v v8 were surprised how easy it is to drive
A real granny car ---yes really.
Wow! Obviously our negative comments inspired you to prove us wrong! :o
Apologies for being such an a$$ in that Vortex thread - you came across as one of the usual dreamers who has a silly idea and no clue how to do it. Obviously that is very far from the truth and you made the silly idea actually work :D
Nicely done 8)
Lee you should whack another 40V in the boot
Just for good measure...
Then that could be considered Excessive Excessivness..
This is unreal. If only my wife would let me do it.
Where did you get the engine from? Must have cost a bit.
But is it economical Lee 8)
Stick some big fat stick rubber on the front one day and take it to the drags, be good to see some numbers.
BB---It's a granny car--road car--daily driver
It was getting 12 litres per 100k with the 32v v8
Yes a lot worse if it's driven hard ---
And no drags--To my mind drags are a good way to destroy things and that is not what I am into.
A drag is only as hard on a car as a hill start with people on board or something like that.
It would not hurt your car and I bet you would find it fun and it would be great to see some numbers.
I think it would be a little hard to get away even though you have good front end weight but would pull very hard at the end.
Your just old school and don't like changing down around corners eh Lee :laugh:
any more updates or pictures?......i wanna see and hear this thing for myself!!!....awesome!
pics-----The inlet manifold has to have it's lid on yet but you get the drift if it
Water runs thru the cores end to end.
Just starting to build the new 3"exhaust and extractors--
Still work in progress
pic------Had trouble finding some where to attach a mounting to the front of the motor so I made a 10mm
plate that sits between the inlet manifold and the engine. So the the mounting is carried by 20x 6 mm bolts and a few 10 mm. This plate will also support the blower.
Yes a bit strange
Nice work, are those cut up 1.8t manifolds?
Yes and what a hassle to find two large hole AGU manifolds--
And yes the engine sits in the Polo engine bay perfect and the hydroboost brake system looks very cool---Thanks for your help Mike

On behalf of all the Antipodean innovaters here Mikki your apology is accepted. ;D Remember we're only a hundred and a half old here so still mostly have the 'if-you-want-it-done-then-do-it-yourself' attitude, however sadly I reckon it is quickly disappearing as you can read from other threads around here.
I reckon Lee is a talented innovator, very understated and modest but the engineering on his ABZ install was great. Only had one drive it in and couldn't keep the grin off my dial the whole time.
There's 4 other V8 conversions that I'm aware of at the moment, and none of them really copy what someone else has done.

nicely said Wilco! :D And Good work Lee!
When can I have a drive? >:D

Small update.
It runs----------------
Still a lot of work to do yet-- but I'm getting there.
Small technical problem I would appreciate some opinion on--
As you are aware the intake system is --throttle body--supercharger--intercooler--intake to engine
I have also installed a Forge type vacuum operated bypass valve after the throttle body with a 25mm pipe to the main manifold.
In theory-- at idle or cruise the bypass should be open and air should be bypassing the blower.
So the problem--
The motor starts and idles at 3k rpm but when the vacuum line is pulled from the bypass valve the revs drop.the vacuum line is sucking air.
When I block and unblock the pipe the revs rise and fall just like operating the throttle-- I have checked for air leaks but have found none.
Any thoughts as to what is happening??
Bypass valve should be before throttlebody
The throttle controls the amount of air introduced into the engine---as I understand it you cannot bypass in or out before the throttle body.
All turbo and S/C cars have bypass valve before throttle body not after.
Are you sure Vert? Bypass by its very
Nature is suppose to let air in when TB is closed. So has to be plenum side.
When you close the throttle it dumps the air between the throttle body and engine back infront of the throttle body
We are talking about a bypass valve as in blow off valve yes?
If so then when the throttle snaps shut vacuum is created which opens the valve to bypass air back to the inlet side of the turbo or S/C.
This valve is always before the throttle body, have never seen it any other way.
Edit, just seen your set up is different........
Ok bit of confusion here... I was thinking idle control valve as opposed to blow off valve. Which bypasses TB.
Johns right it should be in front of the TB. It will be very hard to get idle control with it there. Are you running a Air flow meter?
The Link computer uses data from throttle position and air mass from within the manifold --
so no there is nothing before the throttle body other than the air cleaner.
The bypass valve should be introducing an air circuit from the TB straight to the intake, removing the blower and intercooler from the circuit.
The TB still has to meter the air going to the valve/intake so, the bypass needs to be after the TB right?
So, it should kinda sound like Throttle body - bypass intake - blower - intercooler - bypass outlet - intake manifold.
That's my 2c's worth

This is the way i kinda understood it....
I don't think we're talking about a blow-off-valve here.
He wants to bypass the blower at idle/cruise, not dump excess boost pressure in the intake tract.
Unless I'm thinking about this the wrong way.
Might need one of these
http://www.trademe.co.nz/motors/car-parts-accessories/performance/carburation-induction/auction-516395047.htm
Yes saw that and his comment about blow off compared to butterfly valve was interesting.
I was working on the car today and it runs but only at 4000rpm--this with the bypass valve wide open.
I cannot figure out why when the engine is running that if I pull the the vacuum line off the bypass the revs drop .
by putting my thumb on the v/line the engine can be reved as if the throttle has been opened.
Have I a air leak ??
Post some pictures of that area Lee, might help us understand better how you have fitted the valve and where.
Isn't your you bypass valve your air leak. Or am i missing something. It being open is effectively another throttle that's why its at 4000rpm
What I was thinking...................hence having it before the T/B but then without seeing your set up...... :-\
I'll put up some pics tomorrow
Just re read your original post and your set up is what I have on my 05 Mustang, air in through T/B, through S/C through intercooler into engine.
In theory you don't need a bypass valve as the throttle body doesn't see any boost at any time, its purely there the meter air going in.
I was thinking about having an external S/C or Turbo hence the need to bypass boost when T/B is closed which is why you'd need a valve.
I agree with John. If the tb is before SC what are you trying to bypass? When you close the throttle there is no air getting to the SC or engine so nothing to bypass?
Two things.
1 is an idle valve. This you need when you have a complete air shut off system at the butterfly like an ABF engine.
The throttle closes and hits the idle switch which then opens the electronically controlled idle valve that takes air at a controlled amount straight from the intake snorkel before the air temp sensor, MAF and obviously the throttle body.
To do away with this system you have to close up all the intake holes where the idle valve was etc and make a stop that holds the butterfly open so as to allow enough air to idle.
2 is a blow off valve, which can only work if everything is before the throttle body so that the butterfly can close and block out the incoming boosted air and create a vacume in the manifold fast enough to allow a vacume valve in the intake system to be activated and vent that air out to the atmosphere WOOOSSSSHHHH.
Then I guess 3 which is a turbo wastegate which is a safety valve to stop too much boost even with the throttle wide open cause the air just can't take that much AIR man!
But that is not needed really on a SC car is it unless your maybe doing big high revs off throttle runs? But I think more of a idle switch SC bypass would be used.
I think what is happening is that you might be just getting too much boost from thee SC even at idle and you need to bypass the SC at idle?
My thoughts anyway :P
Small update
Solved my 4k idling problem--turned out to be 0 rings in the intercooler not seating properly creating air leaks--
Have driven the car a couple of times now-- but the blower seals blew and oil went everywhere.
So the blower is off and about to get new bearings and seals.
The 3" exhaust is a very loud problem and have Andy helping with a couple of options to keep it below 95db for the cert.
Good things are the excellent clutch and gearbox--they were total unknowns. Gearing is 100k in 5th @ 2000rpm
The motor too is excellent --as well as it should be with 90k on it
Otherwise not much to report --it should be back on the road soon
Well the new bearings and seals went into the Sprintex and today I put it all back on the motor.
Started it up and it idles nicely--very pleasing indeed
Once I cure the loud exhaust it will go for cert and then dyno tuning.
So not too far off being my daily again
This new engine, adapter plate, another gearbox and the Hydroboost braking has taken alot more time than I expected.
It's been 6 months in the oven
Awesome! Lets take it to the drags! >:D
I have some sticky rubber!
The Wof guys will bug out when they see this.
Such a cool project
I think it sounds perfect as it is now
This is:
- one of the coolest things I've ever seen
- my favourite VW so far
- very impressive in concept and workmanship
it's a well reserved and humble axe wielding psychopath.
Well done, keep the pics and details coming. I hope there's a video install at some stage.
How are things going now - been a while since last update?
Can't believe i hadn't seem this thread before despite being here for more'n 5 years - absolutely bonkers - but in a good way 8) >:D
Hey guys
Haven't posted much lately but thought you might be interested in the next Polo V8 incarnation
The last supercharged implant was not a success as the blower blew up and the the drive shaft hit one of the external oil filter feeds and cracked the block.
After a lot of stuffing round I ended up deciding the BFM motor was no longer applicable.
I happened upon a later S4 4.2 40v chain drive engine from euroline which was just basically spare parts.
The engine was rebuilt using missing parts from Wolf auto parts in America----
So this new engine BBK is lighter and smaller than the BFM and fits the Polo engine bay with room to spare.
As it has variable cams I was not able to use the Link computer that has powered so many Polo incarnations
I decided to go mega squirt as the complete deal was half the price of the newer Links that were needed for the cams
So today it is all running and ready for a WOF after a long long rebuild
Very cool lee. It should make more power too? How have you found the megasquirt? Did you go with the pro?
The newer Link was too expensive when you add everything including final tuning compared to megasquirt $1300.00 for ECU -4 coils -crank angle wheel and sensor inc gst . Very easy to install even for a non electronics guy like me.
Been dealing with Jared from http://www.megasquirtnz.co.nz/ and he has been most helpful and very tolerent .
With the big bore exhaust and megasquirt I can expect the 360 horses that the stock engine produces maybe more.
I will take it to Jared in Tauranga for final dyno tuning in a week or two...
Will try to get some pics up
Sounds awesome Lee, look forward to hearing the results and seeing how the engine fits.
'...and fits the Polo engine bay with room to spare." A masterful statement of relativity Lee!
W.
It's true --the chain engine is about 50mm shorter and about 60mm narrower than the BFM belt drive V8..
Had it out on the road today before it's WOF next week...It's not tuned properly yet so yes it's fast but not devastating yet
Whole car is still around 1050kg ...
Getting there.....
THis is the old BFM motor that I was running in the Polo

Just a quick update
Car is registered and warranted and dynoed to 291hp@ the wheels
Torque is basically flat from 1800rpm to redline 241-247 foot lb
So back on the road and usable again

Hi guy's

ITB's? What are they off? 4AGE?
Suzuki 1000 42mm ITB's which fit on the A4 short manifolds which fit the v8 inlet perfectly.
Verry nice project, i think the sound is great aswel!
Quick question, where did you get the adapter to fit the VR6 gearbox on the V8 engine?
And what flywheel with clutch are you using?
Hey
It is now seven years since I was working this project and it has been since sold to a guy in Dunedin who is further developing it as a road car.
but to answer your question the flywheel and clutch is just standard VR6.
The adaptor plate was just hand made.
Cheers
Thanks for the reply.
Does the original flywheel fit in one go on the V8 crank?
Or does it need modifications?
I can see there are adapters for sale to mount a VR6 engine on to the Audi gearbox, but not the other way around.
Can i ask how you made it, and how did you manage to align the gearbox main shaft to the center of the engine crank?
And was it 2 cm steel, or alloy?
Thanks again for your reply.
If I remember correctly yes the VR6 flywheel will just bolt on.
As I used a Golf diesel 5 speed box the starter motor fits fine, although the flywheel needed to be packed out slightly.
To make the adapter plate was just making a paper out line of surfaces and cutting out it out of 10mm steel.
The key to getting them aligned is turning up a plug that inserts into the crankshaft and slides over the gearbox shaft.
Also with the V8 there is little room for the driveshaft gearbox flange and I had to use a smaller dia CV.
It is possible
Okay, so you used a Golf 4 diesel gearbox?
Or a Golf 3 VR6 gearbox with the diesel starter motor?
You had to shimm the flywheel a little on the crankshaft to stick it out far enough to make the starter motor work?
So on the right side of the gearbox you used a smaller flange with cv, do you still know from what car that was?
How did it drive when it was ready?
Could the original shocks handle the weight, and would the nose turn correctly in corners?
I am thinking about building a front V8 mounted engine, or a mid mounted engine.
I am first looking for the best way to do it, it also needs to be safe and road legal.
Best to PM me
