: Performer RPM to Super Victor swap. What were your results?
Ballistic Aug 10th, 01, 11:48 AM I've got a stout little 355 in my '68, but the bug for more power has bitten and I'm considering the Super Victor manifold.
If anyone would care to share their results in swapping the RPM for the Victor, or if you have the Super Victor, how do you like it? I'd be interested in hearing how this manifold works for you.
Thanks,
-Ballistic
nitrous383 Aug 10th, 01, 09:08 PM Ive seen dyno results on a 500hp small block chevy with a performer rpm only gain 7 hp swapping a victor jr intake.I think if your cam is designed for rpms that dont exceed 6500 you should stay with the rpm intake,not only that but on the street what you feel is torque.The performer rpm will give you better torque and nearly as good hp unless you have,or are planning to get larger cam that could use that big intake.The performer rpm is the best street performance intake period.I bet alot of guys that are running the victor intakes would be better off with the rpm.Just my .02 cents
panic Aug 11th, 01, 03:57 AM If you think you need more top end power, I would try a smaller less aggresive single plane, such as the Victor JR. (less pelnum volume, smaller runners). The Super is for very high RPM.

Ballistic Aug 11th, 01, 04:21 AM Do you have a link to those dyno results?
I'm running a Comp 280S solid cam w/ ported Sportsman IIs, and although what I have is a very good combination, I'm ready to step it up a notch.
I have a current best ET of 12.67 @ 107. If I do the manifold swap, I would likely be sliding in a little nastier cam, probably the Comp XR280 solid roller.
I don't think that the RPM would be the correct manifold for the XR280 cam, but I would like to hear from someone who has personally switched from one to the other.

RickD Aug 13th, 01, 02:05 AM The dyno charts I've seen show the modest gain at peak rpm. The Performer RPM is better for most of the curve which translates to a better behaved street motor.

67RS502 Aug 13th, 01, 08:20 AM It all comes down to RPM.
1. The RPM intake will usually make more HP & TQ below 4500, and the Vicktor JR will make more HP & TQ above 4500. You just need to see where your engine spends most of the time going down the track. If you shift and the RPM doesnt drop down below 4500, it would be worth it to try a Victor JR.
2. The other thing to consider is the lounch RPM. With the weight, stall and gear of the car in consideration you need to figure out the way it leaves. Does it leave where the RPM is able to come up to 4500 pretty quick?
If so the Victor JR would be worth a try. If its lazy off the line the a Victor JR. could hurt it ET. http://www.camaros.net/forum/smile.gif

caribbean camaro Aug 13th, 01, 09:42 AM I agree with the others
be very wary of the high rise single plane unless you have turned the cam and importantly the rest of the combination to hi rpm mode - ie. you can live without the early torque
you probably enjoy good torque now and believe me an engine without that on the street is an awful feeling - I have one with a victor jr and but for having intentions of going further with my engine I would have swapped it out - as I (its hard to admit) really have a street engine which I tried to build with dreams of tearing up the strip
as long as you wish to be good on the street, keep your power band in the lower rpms as much as possible
however if you must, my compromise would possibly be a Torker
Ballistic Aug 13th, 01, 03:11 PM Streetability is a minor concern with this car. While it is street driven, my primary focus at this time is increasing horsepower.
I havn't been able to find any back to back dyno tests of a similar combination, so maybe I'll have to perform my own comparison. http://www.camaros.net/forum/smile.gif
I'm on the verge of buying the intake just to play around with. I'm seriously considering trying the Super Vic on my current motor (expecting that the Victor would be slower), then, after I put the solid roller in, trying both manifolds on it to see first hand which is better.
86z28 Aug 13th, 01, 03:32 PM I agree with the others BUT if you ever run nitrous the victor jr. is the way to go.
