Not something I've thought of before, but have you, or anyone else, used a fuel level switch in the surge/swirl tank to kill the boost or otherwise warn of a low level before it leans out?
Could also be applicable to dry sump oil tanks.
These are my thoughts and opinions - sometimes I'm wrong, but not often ;-)

I've installed a fuel pressure sender in Golf for exactly this, but not a fuel level sender.

That didn't go to plan.

1. Drain plug in sump wasn't factory, sump has been helicoiled at some point and the plug was tapered not parallel thread, pitch was also finer than factory plug.  Ended up pulling sump off to get a proper look and make sure no bits of helicoil lurking around.

2. From discussions with Dave at Tunetechnic and Phil I've decided to install an external Bosch 044 and use the stock in tank pump as a lift pump as per how John and Phil had it running with the big turbo motor.  The stock in tank is probably a standard Golf mark 4 1.8T pump and they have a lower flow rating than the 225bhp BAM S3 motors.  The in tank is a nightmare to remove and refit due to rollcage, so I'm just going Bosch 044 as we know it will work and be more than enough for what this spec motor can do.



Very interesting move on the fuel supply.
a brand new stock Cupra R pump could have easily flowed around 350hp. But as we all know how you work?
Is usually err... the side of caution, which is good to see you going further and having ample fuel supply in surplus now.

I weighed it up, but the cost of new Bosch 044 was bugger all and much easier to fit than new in tank pump.  The roll cage makes it very fiddly to remove and even harder to refit.

Only drawback of the 044 in my mind will be the noise!

Injectors are maxed out so that will have to be it for now.  Water getting pretty hot now after 6-7 laps of Hampton downs.

Much more will need rods, flywheel and clutch.  I've spent way too much recently just to get to this point.

So did a track day at Hampton Downs on National circuit.

Car goes well.

Water starts to get too hot towards end of 15 minute session, so trying an external Oil Cooler.  19 row from NZKW.

Dummied up with some shoddy home made brackets.  Fitted into bottom front corner of bumper which is slightly obscured by intercooler piping, but I think at least there it won't be obscuring radiator or intercooler.

Tidied up Oil Cooler brackets today, but ran out of time to get some proper nuts and bolts for them.

The other 2 areas that could do with improvement for track work are proper track tyres and the front brakes need more feel.

So I fiddled around with the old AP 4 pots that were on Golf and trail fitted 1 side to the Vento.  A small lug needed to be ground off the hub to clear inside face of rotor, but so far everything else looks to fit directly, even the hoses are the right length.
