590HP 4G63 Time Attack EVO 6 | Clubsprint Racing [TECH TALK]

The 2.3L 4G63 in this EVO 6 can produce up to 590HP, but why is that not necessarily a good thing?

Benjamin Perry of Benchmark Solutions runs us through the Evolution Racing Spares EVO 6 which took out first place honours in the Clubsprint Class at the last World Time Attack Challenge. Running up to 590HP from 37 PSI (440KW at 2.5 Bar) the team actually turned down the boost from the
Garrett GTX3576R GEN II in order to make suspension and driver changes in order to get a PB out of both around Sydney Motorsports Park.

The Micks Motorsport prepped 2.3L Mitsubishi 4G63 is controlled by a MoTeC M150 ECU which also takes care of the factory MIVEC and ACD (Active Center Differential) systems. Chasing reliability after a turbo gasket failure last season, Plazmaman Plazmaclamps clamps have been fitted and for better performance, the throttle body and intercooler plumbing have been downsized. Often in the performance world it is mistakenly assumed that a bigger throttle body will give you better performance, however as discussed here that is not the case.
