I will post the dyno sheet on Monday but I can say that the HP finally crests at 8400 RPM. The turbos come on strong at 4500. As far as the smoke goes, I believe it is a combination of a bad scavenge pump along with not enough crankcase ventilation. I am still running the stock PCV valve so that may have to go!!

Nah, the stroked guys are still ahead..... We just have really good heads, a great intake manifold, some really big turbos and a kick ass computer to our benefit!! I am very pleased though how the HP never falls off all the way up to 8400!!

larry if you look at the PCV nipple on the back of the driver side valvecover, its restricted on the inside quite small (towards the inside). i drilled mine out to match the ID of the nipple to help vent pressure once the manifold is boosted and the PCV valve closes

Charlies intake is doing great, and seeing the power just shoot up is a beautiful thing. Dave at headgames did an amazing job too! I took it for a very quick blast on the street for a couple gears. HOLY CRAP!!! Feels awesome, oh and those mickey's HOOK

now i see on the green run the power goes all the way to the end at 8400. on the other runs it drops off quickly just before that. is that quick drop just where you let off the throttle?
any plans to rev it higher? only curious because id like to see how the manifold handles 9000rpm... but results are ****in rad anyway!
