Default What power

My mate has a 2wd cossie with the following spec

Mild Head Porting
Standard Comp
T34.55
400s
4x4 Inlet Manifold
2wd Exhaust Manifold
Live Map on L6
29psi Spike, 23psi Held.

What sort of power and torque do you think it should make ?

With a good sound engine no reason why it shouldnt do 370- 380 with a tad more boost held

I don't know masses about YB, but I Churchys made around 360bhp from memory (a proper 360bhp!!) and it looked like the cams were the restriction. That was on a larger turbine housing.

Churchy will kill you for saying 360bhp! It was 371bhp last time! The same day as my mk1 fez made 82bhp!

Ones i've done on greens push out nearly that

saff @ 346 bhp
escos @ 344 bhp

lot of factors depend on bhp mine i'd guess has lost around 15 bhp due to worn and high miles engine

being everything ok looking around 360 bhp poss more as that held boost seems a bit low/safe for me
