does anybody know what accounts for the dif in H.P. between an S2 and a 968? the engine specs, bore, stroke etc. are identical except for a very slight dif in compression ratio ( 10.9:1 vs. 11:1) could the variocam head on the 968 account for 20-30 hp?

 

Yeah, something like that... I beleive the compression and variocam give the 968 somewhere around 30 hp more....don't quote me on that, I'm not positive...

 

that was quick! thx
