01 BERGER CAMARO SS

iTrader: (77)

Im debating wut setup to use. Im building a fully built 348 for my Hawk . Car will have a 9", full suspention, every single mod and a 200 shot of nitrous. I do however want to be able to drive it once every 2 weeks . I have both intakes here at my shop , just dont know which one will make more power with out them being ported. Both will use a 90mm TB. What do you guys think???

it all depends...what are the goals????

would like to know this as well. I am going with a huge cam, with some great heads and am building a 346 with as much top end power as possible, because it will already have plenty of torque for a 2400lb car.

I think I would go with the Vic just to be different than every other LS on the block right now.

any more opinions on this?

Vic Jr. with 90' elbow is a loser....go with the FAST 90. Way more TQ and area under the curve...same or higher peak power numbers.

Use the search feature (if its working properly)....alot of other threads that have hashed this same issue.

Have the FAST properly ported for even more gains.

put the vic jr on and sell me your FAST 90!

VH5150

for a street car yes, maybe... but 7000-7500 rpm car no way.. the vic is the clear winner... dyno's are bullshit... ill prove you wrong soon enough...

not hard to believe!

I've had both on a 408 and peak to peak the vic runs away. By as much as 18 hp with a loss of torque with the vic up to 4200 where the vic made fun of the fast90. But I also spin to 7700 so for a street car I'd go with the 90. Since I just reread your post sell the fast 90.

Fact not fiction. Have the reciepts/dyno graphs to prove it.

On my 416" that was cammed for as much low end torque/rwhp as possible, the Vic/elbow lost a bunch under the curve. My junk doesn't live at 7500+ so it wasn't worth the loss to me.

Another Vengeance ported FAST will take jr's place.

There are folks who are doing well w/the combo, but big rpm's and very different VE's are key-

Yeah, it's different, and it sure is perty, but the FAST can be just as bling-





On a side note, I am going to run it NA and hose it at the Snap On race next weekend just to get a real world comparo between it and the FAST.

That square elbow looks wrong. Read between the lines in the above posts.

Hhmmm....Ok. So I read between the lines. Under the lines. Over the lines, before and after the lines. Said Vic jr. and 90mm TB on a 346.

What are you seeing "between the lines" that I'm not?

If he's speaking of the shorter elbow/top mounted 90mm TB then my bad, but per his description, it sounded like it sounded.

I stand by my experience with my parts-

I heard that with the vic Jr its the elbow that kills its performance. I was thining of going with a vic jr. 4150 4bbl carb and a big *** air cleaner stickin through the hood. (this is going in an RX7 so no clearence issues with the windshield) And I hear this setup is pretty bad *** on motors that like to spin a little higher. I am goign to be spinning mine to 7000-7200rpm. WIth a big cam and some ported Ls6 heads

Its a more expensive setup than a fast so I wanna make sure its even worth the extra money

From all of the dyno graphs that I've seen comparing the two the Vic really is a looser below 6800. So the question that hasn't been answered is, What rpm are you opperating in? If the answer is that it's a drag mostly motor that shifts at 8200 rpm, sure go vic, but otherwise... I think it's obvious.

Also, I highly doubt that the elbows are killing power vs a tb with no spacer. The plenum volume that exists in a stock vic is only a fraction of that in the fast. The extra volume of the elbow is desperately needed.

VH5150

some of you peeps are nuts... have the peeps who tried the vic picked the right cam?? prob. not... putting a cam that makes peak power from 6000-6800 rpm's on a vic aint gonna work... you need a cam that makes peak power from 7000-8000 rpm's at least.. proven fact.. try a different cam and you will be surprised...

VH5150

well no **** buddy... look at what you just wrote... cammed for as much low-end rwhp/tq as possible... try a diff cam and the vic will **** all over that fast

MNR-0

OK. Tell me how an out of the box Vic-Jr can make 40rwhp more (and more down low but not as much) over an LS6 manifold with stock heads? One was fitted in OZ a few weeks back and that's just what happened.

The key difference here I see is that crazy elbow. The car I am talking about was fitted with a 4bbl TB. If it was blown then no dramas. But a square intake?

And reading between the lines, yes, I am talking about that elbow. Note how carefully worded the above posts are about THAT combo.

Known fact - the LS2/6 runners are too long for top end above 6000. A Vic-Jr/GMPP will annihialate a FAST if the tuner knows what he is doing and the right TB is used. Respectfully, if someone can't make power out of these puppies then it's back to EFI101 for them.

well said... just out of curosity...you dont like the elbow..???
I will be running and elbow similar on my 01 vette due to hood clearence issues.. any comment on my application??
