yeh you would expect that to make more, but it is just 4psi, std correction too, sae correction the numbers would be high 680s... still that hp in that car is a rocket, you really really don't need more

planning to upgrade from 6-rib to 8-rib with 4.0 pulley instead of 4.75 with pistons but still not sure if I'll leave the ti rods or not!

are you still at stock 11/1 compression? if so that is where i'm at as well... i've thought about doing a boost setup too, but its soo cramped in my engine bay it would cost a fortune just to get everything made to fit in a procharger or turbo kit... and i'm not a fan of positive displacement blowers... plus with the cam i have now my dynamic compression is really low so i'm giving up a bit of power... need to mill my heads to 62cc for 11.6 and that would put my dynamic in the low to mid 8s vs the 7.8 its at right now... i guess your gonna do meth with more boost? if you make 715 at 4 you should see maybe 850ish with 8 right?

the tuner I work with is not tunning with meth for a reason he said what will happen if the pump lagged or not worked while racing? "A blown engine" that's why I didn't use a meth btw the meth kit is on my car but it's useless about the compression I'll spray while maxing the D1 that's why I need it do be lowered about E85 it's not available in Kuwait yet.

Well it pulls about 12* of timing and feels like a turd.
