FAST Intake???
FAST Intake??? Hello all,
I have searched everywhere and have read almost everything about the FAST 90mm intake. I was going to get this port matched along with the NW 90mm TB, until now. I was talking to craig from GTP heads and he told me to stick with the LS6 due to the torque loss unless Im going to go bigger than a 400cu in motor, which I dont plan on in the future. Is this true or should I just go ahead and get it anyways?????????? FYI I plan on doin heads and cam along with all my bolt on's. Just so you guys will know what all I will have on the car....
Thanks

Get the intake. There is no torque loss, and head/cam cars LOVE that intake. Get it port matched and tuned, and looks like you're making a good choice with the TB. 
Let us know how it turns out.
Here's my dyno graph btw. Car has a nice torque curve.

I have seen an article, not sure where-Hot Rod or Hot Rodding, which did an stock ls1, ls6 and fast intake comparison with and without a cam upgrade.
It did show power increases over the LS6 of about 10hp i believe and similar torque, but did show a drop in low and mid rpm torque numbers...
I too am looking at this fast intake with a 90mm tb for my Z06, but like you need more real life stores before i do this....
My local speed shop, did a fast intake to a stock Z06 and did show gains in hp & torque up top or peak, but not sure about the bottom end????
Anyone else have info on this subject???

The only reason you should have any kind of loss from that 90mm intake is if the car isn't tuned properly. The increase in air will cause the car to richen itself up to compensate, and if you don't fix that then you could experience a loss of power down low. I know for a fact that my car was a DOG before I got it tuned with the 90mm intake.

Speaking of which, I have a brand new in box part#30-54003 90mm FAST intake for sale/trade. I need the 30-54001 for smaller TB, long tubes, ORY, o2 sims, stage 2 heads, etc. Anything, cash or parts more or less, make an offer if any of you are up to it!!!

what the hell is port matching the tb to the intake.. i may go with the smaller 78mm and run the stock tb.. i cant imagine spending 1200$ or something like that on intake and tb for 10-15rwhp when that would almost buy me heads adding prolly 40 lol, after heads im def. getting one!

if you are going to get radical with your heads and cam do the FAST intake, but if they are only mild then stick to an LS6. Fbody.com posted a thread that compared the LS1,LS2,LS6 and FAst intakes and throttle bodies, the best combo was the LS6 and FASt 90mm throttle body. This car had a mild cam, headers, exhaust, and tuning. So for the money the FAST intake really is not worth it, Get the Ls6 and port it.

i know that TSP makes a 85mm lid with a maf.
If your gonna go heads/cam, i would definitely get the 90mm combo. The bigger your cam the more air it will move; therefore the more air you can supply it the better. Also, practically everything can be resolved with a proper tune.....
my opinion, go for it. Even now!! Get it, tune it.....enjoy and when you get the heads/cam, tune it again. (which you should anyways if you want to get every ounce of pwer from any heads/cam package.

I've still got a lot to buy before I would think about spending $1000+ on a FAST setup.
I am soon ordering duals, SFC, probably shocks, HPTuners w/wideband, etc. Then I still have to get a better rearend ($$$) and the heads/cam. After that, if I still want a little more power, I would consider things like the FAST setup, EWP, changing to QTP HVC headers, etc.
Besides, I don't think TSP is making lids right now (still problems with their supplier as far as I know).
I would love to have the setup, but it will have to wait.

Where does this information come from? Experience or opinion? A 90mm TB on a 90mm Fast intake? Not good, especially since an adapter would be needed. I gained 20hp with a NW 90mm and a 90mm Fast intake: 382HP............Best 1/8th...7.199 95.79 1.571. I think thats good bang for the buck. What other mods will produce that for the cost? Mine is a 346. See mods in sig.

ok guys here are the links to the DYNO results for the LS1,LS2,LS6, and FAST intake manifolds. They match them up with the FAST 78mm and 90mm throttle bodies. Check it out you might think twice.
