Performer VS Performer RPM
I have a edelbrock performer EPS on my car now, my buddy gave me a Performer RPM. My question is will it be worth changing intakes?, will I even notice a difference? my car is a 82 firebird with a 305 LE9 out of a 84 chevy 1/2 ton truck, its got a 1805 Edelbrock carb, flowtech 1" 5/8 headers and 3" exhaust with a flowmaster muffler.

Re: Performer VS Performer RPM
I thought most TGO folks agreed that the Performer wasn't worth the money, but the Performer RPM was the intake of choice? At least that's what I read over the years.

Re: Performer VS Performer RPM

Re: Performer VS Performer RPM
The Performer is an entry level intake,that is a little better than stock,but not a whole lot.The Performer RPM is a much better flowing intake,with more hp potential.However,on a stock 305 without any other modifications,I doubt you'd see any noticable gain,and you might even see a small loss in off idle performance.Intakes are like any other part of an engine,bigger does not always mean better.

Re: Performer VS Performer RPM
I actually measured my performer non-rpm today, and the port size is 1.2x1.9, so it's a bit smaller than a 1205 gasket which is considered a hot street port.
For comparison sake, a stock TPI baseplate is 1.20x1.96, so the performer is close to stock.
I'm assuming the RPM is spot-on at 1.20x2.04 which is what similar performance manifolds measure out at, but I don't have one to measure.

Re: Performer VS Performer RPM
I glanced at a performer EPS once. Looked like a slightly smaller version of the RPM wasnt to interested in comparing it to a stock performer which just by glance it was larger. The RPM is considered a high performance dual plane intake. The perforomer and EPS are stock replacments the EPS is middle of the road from what ive read with slightly better flow then a performer intake. The RPM is a great intake I run one on my bird and I use it for a DD and I have had great results with it.

Re: Performer VS Performer RPM
I currently run that intake on my l69 305. When I swapped over to it I really didn't notice a whole lot of gain over my original intake tho.

Re: Performer VS Performer RPM
The performer rpm. I imagine you'll have a little bit of gain but nothing drastic. Probably 6 or 7 more hp and 2 or 3lb torque. If you already have it and it's a sunny day might as well go ahead and put it on but don't expect to be blown away by the results. It is a good intake tho. Also your powerband will probably shift up 500ish rpms.
