The M42 head does flow very well, and i run 10:1 comp ratio. 215kw @ 0.8bar. Bore: 84mm.
U see there the difference comes in, Comp ration on the Ca is 8.5:1, I have a toatal standard head, the .48 was already laggy and it was a T3 compressor housing...a T4 AR 60 will need more flow to spool before 4000 rpm?
What do you think??
