I finally got the timing up on the car today
635whp at 17psi
886whp 741 ft/lbs at 29-28psi
My a/f ratio was aroung 11.68 and i wanted to maintain 11.2 so the more i was adding fuel the more the power was going down. i did one 886whp one 872whp, 861whp after adding way more fuel it went down to 837, 832.
i should have kept it around 11.7 and play with the timing from there
i maybe would have hit higher.. who knows maybe 900
i am pretty happy with these number though
the time before on the dyno i pull out 652whp at 25psi but 8 degree of timing because i was having boost issue. so now i cranked it up and at 29-28psi the engin is seeing 18degree of timing
next sumer i am hoping for more.

thanks guys.
the benifit of the intake manifold is great for sure but i never had the setup with the normal intake.
here is the graph.
The guy that was logging it on the dyno computer stopped the reading earlier. but usually it was making max whp 100rpm later then this pass.
