upgrade from LS^ to 92 or 102 FAST
upgrade from LS^ to 92 or 102 FAST Just wondering what gains people are getting ... i seen an old post for a 90/90 gaining about 28 HP on a similar set up as mine. I dont wanna go to the 102 if i am only going to see 2-3 HP gain for all the extra work i am going with a 100 MM MAF on my 100MM lid 
It all depends on the mods. A stock car won't see a big gain. A fully built motor would probably see ~30whp. If your running a 402 with that smallish cam you could get away with the 90mm just fine but the 102 will certainly get you more. Plus, it's just a better intake. I'd bet that 2.5" exhaust isn't helping much either.
With my stock cube 346 I considered the 90/92 route. But I had/have biggger plans. With a 402 I wouldn't think twice about going straight to the 102.

oh yeah my sig doesnt sound right its a dual 2.5 into a 3" cat back well i took the advice and ordered the 102 so i have to see this spring when the 2+ feet of snow melt so i can get it out of the back garage lol
Grats on the 102. I highly suggest the exhaust be your next step. That 3" single is holding you to sub 400 before you start getting losses. Meaning anything over 400bhp and it's costing you power. I'd say single 4" or dual 3".
