Vengeance ported FAST 90, HS roller rockers, NOS Sniper kit The FAST 90 intake was ported by Vengeance Racing. Its the real deal. I saw a significant pickup with this intake. It has about 3000 miles on it, and I have used an oil catch can since I put this on so it is very clean inside. There are NO cracks or anything, and I have all the bolts for it. SOLD!!
The Harland Sharp rockers are the 1.7 non-adjustables. They have about 3000 miles on them, too. $300 + shipping
The NOS Sniper kit is my brother-in-laws. It is new and has never been used. It APPEARS to have everything, but you can see what is in the pics. $225 + shipping

Unfortunately, no. I dynoed 448rwhp before with an LS6/ported stock TB combo. Over the winter last year I put the FAST 90, HS rockers, new duals, 85mm MAF and lid, and 42lb injectors on it, so it would not have been an apples-to-apples comparison anyway. I am confident the car made 500rwhp with the mods. The top end with this intake is pretty amazing.

My guess, the ported FAST and LID maf combo got you ~20rwhp, depending on how aggressive your top end is. The duals may have gotten you 5-10 at most depending on how restrictive your prior catback was. Some people see 0 from duals. The HS rockers got you 0. The injectors really are there to keep you safe unless you ran so lean making the 448 number.
Sorry, just trying to keep things real. I definitely think the ported Fast and intake combo is worth it as I have one myself and noticed a nice gain throughout the rpm range.

Matt,I disagree with alchemist with his #'s and this is not the place to debate #'s.My #'s in real world would be ;manifold=20hp&w/port=25,lid=10hp w/maf=15hp,rr's=5-10hp,and the duals and injectors=maybe 5 each.So I would say that a 50hp is more likely then not.And with a tune your there. Good luck on selling parts and Merry Xmas to all.

Alchemist and I disagree, let's just leave it at that. My heads and cam were running out of breath up top and the car was at 11:1 AFR at WOT. Did I have 500, 490? Who knows. I made a guess.
