But you have to run lower boost.
I am not trying to be an asshole here - but dont you think the actual companys/racers and people with FI cars don't know this and have tried various approaches? - but the bottom line is you cannot get rid of all the excess heat that affects a streetable pumpgas car. Even the Veyron with its 49 intercoolers and 86 radiators reduces power, pulls timing and slows waaaaaaaay down when it gets hot.

The very point of "running lower bost" defeats the purpose of having a super/turbo charged car to begin with.

To put things into perspective, in 2002 Lingenfelter had a 660bhp Twin Turbo C5 Z06... peple bought them, people loved them - LPE built them - but in a road race situation heat is an issue.

Fast forward 5 years to 2007. A number of people have 660bhp NA C5 and C6 Z06's - without heatsoak issues.

Guess which cars are prefered to be used on road race courses?

You see, it doesnt really matter how little boost you runn (for a turbo) or how big of a pulley you put on the supercharger, compressed air heats up - this heat soaks the engine, the heat soaked engine sufferes from pre-ignition with regular fuels and wold self destruct if the cmpoter never senses the knocking and pulled timing - resulting in the car being hot and slow

Didn't you ever figure out why Best Motoring only ever run 3 laps for the their tests? It's because none of those modded turbo cars can run more than 5 laps before they get hot and slow down
