The difference that it makes is so unbelievable.
I'll second that. I was running the a6 and putting 290whp and 250tq @ 18psi. I put the z6 head on and was making 273whp and 240 tq @ 13 psi on the exact same setup (plus the turbo was coming in a tad bit sooner). I stopped at 13 psi cause the seal in the turbo gave out on the dyno so now I'm waiting for parts then it's back to the dyno. 20 psi here I come! Overall I'm very satisfied with the z6.
haha man, i know how u feel... on 22psi i made 294whp on my A6 setup. my friend dynoed after me with a z6 setup, and made 277whp @ 13psi.
i felt like such a chump.
