put wideband on 11.2 at the limiter in 4th stu set up at 11.4 so thats all good but just noticed exhaust housing is a .63 ? shouldnt rs500 t4s be an .82 housing ? i was wondering if thats contributing to egt being abit high as its smaller housing so maybe restricting flow at the top revs?

Rab

I always thought the T4 had an .82 exhuast...... But then, there's THAT many different T4's about.

thats what i thought mate ? sure my old 3 door had an .82 on it.

Rab

All the genuine RS500 T4's were .82 IIRC. But a T4 can be anything I suppose, depends on who built the turbo. ON the bright side, the housings are piss easy to swap over

wes

RS500 T4 has a .63 exhaust housing.

rapidcossie
