so i am going to be buying a new manifold but i am stuck. i am either looking at the rpm air gap or the victor jr. i heard both work well but which one. I currently have the original rpm manifold on my car. what is the difference in the ports between the original rpm and the airgap or are they the same? what will work best with my combo.

-331 stroker
-TFS high port heads
-750 pro form carb(soon to be bought)
-XE282HR-12 comp cam
----232 int./240 exh @ 050, 0.565 int./0.574 exh. lift, range 2,600-6,500
-9.5:1 compression
-stock 5 speed

lol sory colage jst not is me wurkng four

here are some actual test that were done on both. the motor has about the same specs as me. they did dyno test with both and both are about the same. just peak torque number are at different rpm ranges. there are 3 pages check it out sean. oo and yeah i did suspension lol i will get some pics together for you and send them to you. sorry i forgot i was to damn busy with gay school

Maybe for high end 6500+rpm HP. But not for a DD street car that needs mid range torque.



Here is your answer right here Kyle.
The question on the table now is, which is more useful, an extra 20-25 lb-ft through most of the mid range or the slight advantage in high-rpm power? For this particular mild application, the dual-plane would be much better suited for street (and occasional track) use. Ideally, the single-plane intake would be combined with more of everything, more compression, displacement, and even wilder cam timing to maximize power production higher in the rev range.

lol yeah that is basically what i am gonna go off of i think. the only thing is superman is gonna sell me his vistor jr for a good price cause i just took his nice 750 off of his hands. ahhh lol also i was talking to frank(superman) and he said with my nitrous plate the rpm air gap would be horrible. since it is duel plane the higher side will get all of the nitrous and could blow one side of motor. but also i was thinking screw it i will just get fogger system:lol:

vic jr. air gap sucks monkey balls.. :banghead:

or the Wiend Team-G is good single plane as well..

there is no weiand team g for 302 ford i believe. have you tried both manifolds?

i have a torker 2 i would sell cheap

sorry bro looking for a high rise

 

[WHTKNTE]

get the victor.. thats what ill be running

??? why arent you fuel injected??

 

[WHTKNTE]

ooo lol haha nice. thats gonne be nice. how much did that cost you?

 

[WHTKNTE]

yeah bro i beleive you can. its a pretty bad ass set up i would like to do if i could find a cheap F.A.S.T system. and also for sure do it if i could induction

For what it's worth, I wouldn't spray anything with a dual plane on it, If you feel the Vic.JR has too much cross section for your RPM curve, you might rethink the Torquer II, not the greatest manifold out there but with a 1" carb spacer and the plate, it'll have plenty of mid range when you're not on the button...just a thought.

that is what i heard as well. what could i do to get more mid range power from a victor jr. I have a victor jr i can buy right now with ready fogger slots. or if i went with the rpm air gap i could just do fogger set up.

The things you could do to pick up the velocity are only bandaids,a smaller carb, advance timing, fill the plenum, plenum turtle, just get the Vic.JR from Frank, the minor midrange loss's will be nothing compared to the gains when you're on the button, do you know what your heads flow?

i beleive the heads flow in the vecinity of 265-270 cfm. what do you mean by filling the plenum and also plenum turtle? and thank you for the advice I will take in all i can get. i am still young and still learning alot.

 

[WHTKNTE]

At what lift do your heads flow these numbers and do you know what they flow @ .200, the reason i ask is, a "big" manifold coupled with poor low lift flow numbers makes for a pretty lazy street cruiser.
reducing the plenum volumn with epoxy will give more response {with a sacrifice} on the top end, a turtle is an insert that fits the plenum floor, some say they work , others don't.

i actually have the flow chart here on a stock pair just like mine. here is the site to check it out....

so what i was thinking is i am going to just buy the rpm air gap. along with that i am just going to drill into the manifold to make room for a fogger set up. that will take a way the worry for the duel plane problem badnews was stating. i am thinking that will give me best of both worlds, low end torque for streetability and even nitrous flow. what do you think?
