Edelbrock Performer vs Performer RPM vs Air Gap RPM

Regal Beagle · #1 (**permalink**) 02-16-2009, 10:42 AM

I am concerned about hood clearance on my Regal and was wondering if someone could tell me the height differences of the above three Intakes. I currently have Performer and am considering going to either the Performer RPM or Air Gap RPM.

You might have clearence issues with the air gap, but the RPM will clear.

I have about 3 inches clearance with the Performer. Is the Performer PRM aboit 1 inch taller or is it more?

I must have missed it yesterday. Thanks for the tip.
Just for others information the Performer RPM and Air Gap RPM are the same height.....they are .7" taller than the Performer.
I am sure I can make either manifold work.

your welcome...

just curious, does your car and motor build need a 6500rpm+ manifold,,,do you have that much cam and gears in it?

red, in a thread late last year, I tweaked his combo on the Dynosim and picked up 100 hp with a few changes. One of them was an AFR 5028 high-rise, dual-plane intake manifold, so that's probably why he's contemplating the change.

On every Dynosim I have run, the RPM type manifold has made more power and torque than a low-rise manifold such as a standard Performer all the way through the rpm range and more power than a single-plane up through 6500 rpm's, where the single-plane begins to shine. F-BIRD'88 argued this point with me last year. He was right.

Here's the thread....

Tech's advice from my earlier thread was exactly my motivation for the question. It's almost cruising season so the mind is full of ways to spend the money my wallet hasn't got.

Hey, thats the nice thing about Alberta......from 20 below to 20 above in 12 hours....or less. Really just depends on your definition of "almost".

I know from what I read on here that i will be buying a Performer RPM or preferably a Performer RPM Air-Gap intake.
