I know i've posted this before but I got a 50/50 answer. Some say yes and some say no. I know bayer knows what hes talking about but i'm just not sure what to do. I have a stock 2000 camaro z28. So far just a flowmaster exhaust. I want to get the 90/90 FAST manifold and TB. But some say it will actually hurt my horsepower because its just stock right now. I deff. wont keep it stock but the most I will do is prolly all the easy stuff. exhaust, intake, bolt-ons, and that sort of stuff. I dont think i'll go heads and cam but idk i just might. I could also go supercharged. I'm not sure about the big stuff. My ultimate goal is 500 HP. Any suggestions?

 

Anyway.....


wait a sec....










Ok.

No, the FAST 90/90 is used to support internal modded engines.
It'll be a waste of $1000+.

Stock cam = Stock or LS6 intake manifold and TB
Cam only = LS6 intake manifold and ported stock TB.
Heads/cam+ = FAST Intake Manifold and 90mm TB.

As Kraest just said. Don't waste your money on a 90/90 for a stock internal or cam only motor.

 

well could a LS6 intake take 500 hp?

 

At the wheels on stock cubic inches? No. If you're talking 500HP as measured at the engine, easily.

And again, the FAST 90/90 is not only a waste of money on a stock or mild bolt-on car, but often loses power as well.

 

I have a question...I am looking at a 1998 Z28 Camaro LS1, He has a 90mm intake, And an electric fan...I have no idea why this guy but a expensive intake on it when he has nothing done to the car...So my question is will that hurt the car??? Also why would he put a electric fan on it??? Maybe overheating problems???

Thanks!!

All 4th gen f-bodies come from the factory with electric fans.

 

Ok..The guy said that there is a switch inside the car so you can turn it on or off..Thats why I would of thought it was aftermarket, Do you know if that FAST TB would mess anything up??? I dont want to waste 10,000 bucks

Thanks

 

Sounds like he installed a manual fan switch, which honestly isn't needed unless it's a dedicated track car. And the FAST 90/90 setup should be tuned. Some bolt-ons you can get away with on stock programming, but not so much with the FAST setup. And the FAST throttle bodies a couple of years ago had problems with sticking at WOT.

 

well okay no FAST intake or TB. So what do you suggest I do with $500. and what would I basically have to do to get 500 horsepower. im not big on supercharge or anything like that but if I have to okay.

 

Thats why I went with the Nick Williams 90mm throttle body with my FAST 90/90 combo...........no problems to date.

 

Look in the classifieds here and on www.ls1tech.com for an aftermarket lid, a ported stock throttle body, and an LS6 intake. That should be right around $500, and would add another 20-25HP easily - a definite SOTP improvement. When you get more money invest in headers and a quality y-pipe, and maybe swap out the catback for something that makes a little better power. Depending upon what trans you have your next mods will vary. Either way 500HP cannot be done without internal engine work, or some sort of forced induction - mechanical or chemical.

 

what kind of internal engine work? I thought heads and cam didnt do THAT much. do you mean like boring the engine? I have a automatic BTW. so pretty much better air flow in and out but then what?

 

Nah... not too much....Heads/cam/intake only add around 150-200 crank horsepower over full bolt-ons. You're talking about 340rwhp to 480+rwhp with a heads/cam/intake swap.

Your next mods for $500 should be a lid/cai and a real catback (not a piece of crap Flowmaster), then put the rest towards longtube headers.

How can I find out if this is one of the bad FAST intakes or not??? Unless the guy is totally truthful and tells me that it has had problems, but if the guy wants to sell his car he might not be truthful and do what he can to sell it...
