Which makes more power? A FAST 90/90 setup or a Victor Jr EFI manifold w/90mm elbow & TB

Not sure why you're asking this in this section but...

Supposedly the FAST will make more power down low and midrange but the Victor will pull ahead above 6500. So unless you have a very high revving track only car they aren't a better option.

Vic Jr for bigger cubes and higher rpm (with the big cubes). also, the Vic Jr requires cutting up teh cowl.

Victor costs less than the FAST also if Im not mistaken. Mrr23 on here would be the best person to ask. He went from a 90 to a Victor and was happy with it

well i didn't have a fast 90/90. i had the NX intake i switched from. when i swapped, i picked up way better after 3500 rpms with it wanting to keep going past the 6500 limiter i had. i had a 408 motor, so i really felt no loss under 3000 rpms. from what i've read, the FAST seems to be slightly better under 3000 rpms and the vic jr picks up better after 4500 rpms. this is why i went vic jr. as far as the cowl goes, i got the edelbrock elbow for the f-bodies. no cutting of the cowl was needed. if you are going with a 4 bbl TB, then you'll need to live without wipers.

After those pictures I think I'm gonna give the vic jr a try. Also I've been looking at the LS2 typoon manifold, anyone know how it compares to the fast?

there is virtually no difference in price with either intake/tb combos. you can pickup the FAST 92/92 at TSP for 1100 dollars. you will easily spend that with the VJ intake, elbow, fuel rails, and 92 tb. then you will have to buy/build some kind of extension to get it to meet the airlid.

i`ve been going back and forth on the same thoughts for a while and i`m still up in the air on what i want to do, the only thing that could make this more confusing to me is if i had the money to buy either lol

i spent right at $1000.00 doing mine. that included making the fuel line connections from the hard line to the fuel rails and that wonderful home depot air lid to TB connection.

I think I'm gonna go with the typhoon and run a 92mm TB. I'm just gonna have it ported before I put it on. If anyone thinks this is a bad idea let me know.

its a bad idea. stick with either the LS6 intake, 92/92 combo, or the vic jr if you dont mind the extra work and heat soak.

mrr23

iTrader: (3)

oh no, not the 'heat soak' problem.... and what extra work?

i'd hate for a backfire to come along and destroy that $1000 plastic intake. seen that happen enough.

If you are running a big cam that makes power very high and its a track car id say go with the Victor,for a street car I would stay with the FAST for sure.

robert, how was yours around town? seem like you had to give it more gas to leave lights or anything?

I wonder how a V Jr. with that Elbow/90mm would do on a L92 Headed Car vs. the stock L76 Intake..

thndrracer

iTrader: (5)

do they make one yet? i know gm performance has a single plane though

drove just fine. really felt very little difference driving it everyday. granted i had a 408 motor and a 3400 stall. i'll do it again with my next car.

I really appreciate all the info. Also what size elbow are you running? Edelbrock makes three different sizes, ultra low pro, low pro, and high flow. Anyone know what is the biggest one you can use with the stock hood?

Skinny

iTrader: (11)

I have the ultra low profile on mine and I seriously doubt any of the other ones will fit under the stock hood. The point with the lowest clearance is at the mouth of the elbow where the throttle body attaches. There is about 1/2" clearance between that point and the center support rail under my stock TA hood.

As for attaching the TB to the lid, I just put a cone filter right on the mouth of the throttle body.

the one i used is specifically for the f-bodies 3847. i went to home depot and made my special hookup. have pics here on how i modified the airlid to get it all to work. i removed the MAF and went SD.
