I know this has been asked before but i dont care i want fresh opinions.. I can get a good deal on a performer TBI manifold.. what are your opinions on it.. performance wise and all.

------------------
89 RS 305 TBI
Edelbrock 14x3 OE intake, Hypertech Chip, Street & Strip shift kit, flowmaster exhaust w/ high flow catco cat.
Soon: 3.73 gears, posi, Edelbrock TES headers(jet-hot) [I have them all now, just cant afford to get them installed]
AIM:TiMoThY9801
Stereo:
JVC Detachable face cd player w/ 2 Pioneer 12" subs in custom box, powered by Lanzar 600 watt amp.

 

I don't have it but I have heard good things about it. Especially if you get siome good heads and a matching cam. You will have plenty of power then. If not go with the Vortec TBI intake and get some L31 heads. It is cheaper in the long run that way. But if you can get a deal than by all means go for it!

fresh opinion? Its crap.

 

I agree with Pablo. Opinion doesn't lead to power. Testing does. If you want to go fast, test test test, and talk with people who test. SOTP testing isn't worth squat.

 

I HIGHLY recommend getting the Vortec heads!!! I put them on recently and they seem to LOVE TBI, at least with a Comp XE250 cam, anyways, and an Air Gap manifold and Adapter plate. 313hp fresh off the dyno YESTERDAY!!! before the Nascar race, of course... Yes, Pablo, I had to run 20psi to do it with the 1-11/16" TBI. I am a believer that these injectors can take it, too, and my in-dash Auto Meter FP gage is useless, now, I guess. 328hp on SAME motor with Carb and nice HEI, BTW. 400+ lb-ft on both, too, with a NICE FLAT torque curve! 1-3/4" headers, though and 2 (x) 2.5" Flowmaster 30's.

But I think the Air Gap is TOO big of a manifold... Gonna try the Performer Vortec, next.


I digress...

I have heard bad things (flow-wise, power, etc) about dedicated TBI manifolds directly from their manufacturer. If you choose not to believe me, that is your decision. I would go carb/adapter plate, but that is me. Also, this way, you can EASILY go back to carb, for testing or whatever...
