Considering that you are not H/C. You might not really get that much out of it. I saw around 17rwhp difference from big cam and worked heads with stock valves. That was over the stock LS1 intake btw.

Not to mention you will also have to buy a 90mm throttle body. Which is in the neighborhood of another $350-$450...

I have always wondered what a Fast 90/90 would do compared to an ls6, but for me idle to 3500 is as important as 3500-6500. I don't want to lose anything in the normal driving range to gain a few hp up top.

That's why I haven't gotten one yet.

buy an LS6 intake. its what you need. later if you go H/C then buy the 90/90 set up and sell the ls6 for what you paid for it.

what if i port the ls6 intake myself? then the ls6 would become better than the fast right?

no it wont. dont worry about porting it you dont have to. and i hear its hard to port plastic without it melting. just get the LS6 intake and port your Tb if your in the porting mood.

I just purchased the Fast 90 90 setup for my heads and cam camaro.

I cant give any dyno numbers since it is still being built but from what I HEAR people are picking up 30 rwhp on the 90 90 over ls6 with a BIG heads and cam setup.

Just something I heard.

Also.. 20 rwhp over the ls1 intake stock car.. thats what i HEAR though.

best of luck.. Either way u cant go wrong.. it looks hot too lol

Do it right the 1st time. I can't tell you how many times I've bought something, just to upgrade to something bigger a year later. Get the 90/90 and don't look back.

You might gain up top but will likely hurt the mid range. Ls6 intake in the best for anything under 450 hp.

With my tuning and cam, my fast seems to give me the dyno numbers I was looking for.

One thing I have NEVER EVER seen: dyno results of a stock internal car with a 90/90 set-up.

Would be interesting.

I just purchased the Fast 90 and NW 90mm throttle body, and it should be here from Thunder Racing next week. I hope to see a MINIMUM of 20rwhp on my H/C setup, of course more would be better! Currently I have an ls6 intake w/ Thunders ported TB. Cool thing is that I traded my intake + throttle + my MTI clear lid to a friend for The Nick WIlliams throttle body! SO, lets see if $800.00 i spent on a 90/90 was worth it!

but i hear yall talking bout heads and cam well i am only putting a big cam in my car the TSP magic stick 4 to be exact but ill keep the stock heads bc i wanna c what i can get out of them but i will sumtime down the road port my heads myself. so is this combo truly going to hurt my car w/O the heads?? performance wise

with a monster cam like that it shouldnt hurt you to bad.

The fact is, the only dyno graph's i've seen is from 3500-6500 and the fast 90/90 shows a decent gain over the ls6 on a h/c combo.

What I want to see is how it is from 2000-3500? Anyone?

I'm not willing to sacrifice low end drivability for 5-10 hp at 6000 rpm.

ok ya well the cam itself the power band starts at 2300RPM and im goin to have a 3800 stall so there will be a very good power band out of the hole and up top i think my nitrous can take care of the problem above 5000RPM so the ls6 i guess will be the next mod after the stall and tranny rebuild thanks alot guys that was alot of help..

I have
98 Z with stock motor,just switched 90 intake gain-0-2hp.


Back when the FAST first Came out I switched the 78mm(90 wasn't out yet) onto my Firehawk.
Dyno'd it to the most rwhp we could get with the LS6.Switched to the 78mm (on the dyno) and ran it again at same engine temp.We tweeked the tune for the most $$ like the LS6 and gained 20hp15tq pretty much everywhere.Car was 11-1 comp,ported heads,230 Cam.

So,the 78 worked pretty good.Haven't done a back to back with a 90mm like that yet.
