gotcha i see now, so putting a Fast LSX intake on my LS3 is pointless, better off porting my stock one

Well if you were to come across a FAST manifold for like $500 or $600 then I'd say go for it. But those chances are few and far between. So yea a good ported manifold is pretty much the way to go.

Fast Intake with stock Throttlebody got me 4 HP and 4 FtLb TQ at peak a little more in mid-range. looks cool but not worth the money Just been checking my dyno charts I can't believe how much bottom end I lost.Torque down 20 ftlb at 1500 rpm and it doesn't get back to where I was till 3000 rpm, even to slightly higher the rest of the way up. Horse power difference is minimal, slightly higher. My car was really quick out the hole before the manifold change not so much now. What a waste of time and money, I'm thinkin on getting rid of it.

FAST 102R intake and Nick Williams 102 Throttle Body Gave me a 5 HP gain after Dyno tune. Not worth doing on a LS3 with stock Heads. Thats almost $2000 for 5 HP. Now I need bigger Heads and injectors also bigger fuel pump. Not much sense in doing a FAST 102 and a 102 TB with out doing Heads and Injectors. I will say this Trottle responce is very good.

As for price as i paid 900 looks alone it was worth it for me to spend the extra money. When I hear people say it's too much money for the gains it puts out I get it. What I've read on them with head work and a cam gains are better. For me it's about building something I would love every time drove it and looked at it and fast fit that build. Be careful with ported intakes not all gains will be the same with every intake go with a good company.
