Wasn't Ade's just over 600bhp on the DYNO on normal unleaded? So SIMILAR to Lee's in the car

.
And as to your fictional power claims, that's like me saying if I ran my T4 at 40psi, I would have 600bhp

. It just doesn't work like that

.
But you CAN'T run 2.5 bar with a 2wd manifold according to you

. MAKE UP YOUR MIND
