I have a 98 TA with full exhaust and cutout, FTRA, lid, 3400 stall, and cam. The cam and stall were just installed and im looking to get a different intake manifold. My car only dynoed at 351hp and 318tq. They said this was partially due to the stock intake manifold. Should i get the ls6 or the FAST 90/90? How much more hp would the 90/90 make? ws6store.com has the 90/90 for $1149 which seems like an ok price

whats your cam? those seem like very low numbers a LS6 would be just fine and you wouldn't have to get a $500 TB either

i'd go with a ls6 and use the other part of the money on something else

What size is your cam and do you have any head work done or a diff set of heads? Usually the LS6 is good well up into the 400's on hp level..

If you have the money for the FAST, I'd say go for it... I'd also be saving for a set of heads too..

depends on the cam...on a mild cam+stock cube motor, the ls6 will be everything you need (the 90/90 will still make more power, but prob not enough to offset the price). but with a serious cam the power advantage of the 90/90 becomes much more noticable

What is the cam? My car put down 350/350 with my mods in my sig. Anyway, if you don't plan on getting heads I would say go for an ls6 or you could just wait and find a used fast for cheaper.

with that size cam i would go with the ls6 and a poerted tb. if you had a bigger cam then I would say do a fast 90/90.

If you don't mind paying the cost for a FAST intake buy one of those, but for $300-$350 you can get a used LS6 intake from someone here in the parts section or ebay. Go with a LS6 Intake.

Is that a dynojet or mustang dyno...seems really low, especially the torque. My T/A had more torque than that bone stock.

its a stalled a4 what were you expecting with a stock intake.......stalled autos are not dyno queens

With your cam I would not waste money on a fast. They price those as if they were cast in platinum. You may want to wait a bit before getting an intake. The street warrior intake will be out very soon and I have heard some very promising things about it. Do a search, it debuted at SEMA this year and there is a huge thread about it. I think this intake would be great with your set up.

go with a ls6 unless your looking for 550+ rwhp then thats when the fast 90 would be good
