pre s/c

rockdoc · 04-12-2007

Can i mount an additional 0.3 injector pre supercharger to cool the rotors - if i am running a TDR A/A I/C?
My current injection point is a few inches before the Dummy throttle body on pipework on the exit side of intercooler

M3 nozzle "smallest we have" would be quite a lot to add on top of the other m3 you are running, I am affraid you will be over fueling.

I fitted the extra nozzle as a small experiment, it certainly knocked down the temps exiting from my M45 from 250degF to just over 100degF(10min 12psi blast), -BUT- it then had to travel through my TDR A/A I/C -and where before i was seeing temps near ambient to 10deg above ambient , i,m now seeing temps 15deg above ambient.
so in short - it does lower temps from the s/c - but seems to affect the efficiency of the A/A I/C -to the overall detriment of final intake temps.

like i say it was a totally reversable experiment.
