1 BLOWN V8

Hey all:

2002 Camaro A4 built trans with Yank 3,200 stall and 342 gears.

First my mods are: Stcok LS6 intake with a slp ported t/b, tea 5.3 heads stage 1.5, 224/224 571 at 114 lsa, lt headers, tsp y-pipe, magnaflow catback, and rest of the usual bolt ons. I put a little over 400 HP and over 390 torq on a mustang dyno.

Is it worth it to step up to a fast 90 set-up or not? I have heard of people lossing HP and mostly torq on a non stroked motor.

Thanks

You can gain power with a FAST 90 on stock cubes if your heads are decent. You can especially gain power with a ported FAST 90.

I gained 20 hp on mine with a h/c auto car . Defintly worth it.

Just find a vendor with a liberal return policy. If it doesn't work, send it back. I would say that odds are better than not you will see a gain, but there are no guarantees. $1300 is a lot to spend on a "might gain power" item.

as long as your heads do better then 285 cfm there are big gains .... stock intake restricts cfm under 300...... I showed gains when swapping cam only to a LS6 from an LS1 of around 10 horses.... .you will see gains with the 90/90 as well......

Check the dyno forum, there are a couple of graphs of heads/cam cars there with GOOD gains.

Buddy of mine gained 30rwhp on his motor with a ported FAST 90 over an LS6. Big heads and cam.

you WILL be dissapointed... ive seen FAST intakes cause issues. a professionaly built LS1 with heads, cam FAST intake in an A4 car with a stall was SLOWER than my friends bolt on stalled A4. the guy with the built car said that he thought his FAST was causing issues and he wanted to get rid of it.

that would be cool if both cars were identical in everyway...except the F.A.S.T. 90/90.

if he held onto his intake, he can do a dyno comparo, it's easy enough to swap them out...

I have never seen any problems with a fast intake when installed properly. I personally saw a big gain and so has everyone I know that has installed it. Is it a high price item sure it is but I guess it comes down to how serious you are about making every last hp.

What issues are you talking about that you have seen?

Was the issue the throttle body? I've heard plenty of stories that it's crap. That's why you always, always go with the NW 90.

You will gain hp/torque pretty much everywhere when switching to a 90/90 setup from a LS6/ported, even on a cam only car. You don't need heads for it to be beneficial, and for sure not a stroker. If you have better flowing heads, you will see MORE of an increase from the swap than the swap with stock heads, but you'll still be up power.
