I am looking at the edelbrock performer airgap (not the rpm airgap) and the weiand action+plus or the stealth intake...

Do you guys have any experience with these.

The edelbrock is from idle to 5500, the weiand is from idle to 6000 for the action+plus and from idle to 6800 for the stealth.

I will never see higher than 5500, so the air gap is perfect, but I want to play a numbers game...

which is the best streetable, with higher hp numbers, or best design, whatever.

I really am leaning toward the airgap though. It is a really cool concept to have in a street manifold.

let me know whatever you think, because I need to buy one tomorrow.

My old performer SUCKS!!!

I'm going to suggest that you go with the Edelbrock Performer RPM Airgap. After talking to the Edelbrock Techs at some length about my car, they revealed that the Edelbrock RPM series will equal the Performer in Torque figures from 1,500 to 2,500 rpm. After 2,500 RPM the RPM models pull ahead in both Torque and HP output. "One of the best manifolds we have ever produced" was their quote. I've heard that repeated in many, many articles.

I Autocross my car, so bottom end grunt is critical to me . I lost virtually nothing on the bottom end when I switched from the standard Performer series to the RPM series....but I sure picked up a ton of HP on the top end

My vote goes to the Air Gap. I have the Air Gap RPM with a Holley 670 Street Avenger and man does the run now. I had a Weiand Action Plus with my original equip. carb. and it died at about 5200 rpm. The Air Gap and Holley combo will run well into the 6000+ rpm range. Just my opinion on the subject.

So the performer, is not perfered?

I was assuming that since I have a street car that I weekend race, I would be better off with the performer, because it goes from idle, not from 1500.

Does it really matter idle, or 1500?

If so what about the knock-off performance+plus intake the Crosswind.

I can get the polished Crosswind for the same price as the satin Edelbrock.

I just didn't want the crosswind because it goes from 1500, not idle.

Let me know what you guys think. I want to order asap, like tonight, or tomorrow morining.

thanks

Don't waste your money on a " knockoff" . Edelbrock has spent Millions of Dollars on R&D. Cheap copies are just that...inferior copies. They'd be sued to high heaven if they were exactly the same....and in this game " close " is not good enough.
The RPM is consistantly pulls top figures ( Usually #1 ) in back to back manifold tests.

The RPM models pull fine from idle. With a healthy 350 you can blow the rear tires loose from a start any time you like. The idle to 1,500 matters not a hoot on a 350.

Cool... thanks

I am placing my order now... for the rpm airgap.

I appreciate the advice..

Dual Plane high rise manifolds on V8's have been around for a long time. There are many different manufacturers other the Edelbrock.
Edelbrock does not hold a patent on their design or claim it to be patentable. Only the Name "Performer RPM" is copy righted.
Professional Products stuff works fine.

If that is what you want and can save a few bucks go for it.

Imitation is the nicest form of flattery.

The new Edelbrock EPS manifold seems to fall right in the middle of the two other Edelbrock manifolds.

I too looked at the Crosswind polished manifold but decided to use the Edelbrock simply because they did the research and development on the design and they should recieve the sale. My question is this, is the Crosswind an import item from Taiwan or China? Given the huge price difference my guess would be it is import item. Not to sound political or anything, but we need to support our American companies..Just my opinion. Thanks for the letting me sound off.

intake's are about the only good thing they make anymore.

"Imitation is the nicest form of flattery "...doesn't mean it going to be the same thing. And many, many different designs fall short of what the Edelbrock RPM model does..

Vizard's " How to build Horsepower volume two" deals specifically on Carburation and Intake manifolds. He has tested literally hundreds of manifolds....Time and time again the Edelbrock products ( and some by Wiend and Holley ) consistantly come out on top. There is a difference in what works OK and what is the ' King of the Hill"

Manifold designs are patented BTW. Not the overall design such as " Dual Plane or " Single plane " but the specific runner shapes and sizes and plenum's. R&D can be patented. Copiers have to change runner size or shape just a bit to ensure that they don't get sued. That of course can totally screw up the design...or perhaps not affect it at all. Guess who's doing the R&D for these companies? Hint...it ain't them.

All you have to do is add 1\4" to the manifold carb base and that may be sufficient to avoid litigation. If you make an " exact " copy though ( Grinding off just the name for example ) then you CAN be sued.

I too would rather by something from America or Canada than some Taiwanese " knock off ". In addition to supplying jobs and supporting our countries I know that the foundaries are good and the machining is good. Not so with some countries such as Taiwan, Thailand ( very,very bad ) and China. I've seen axle seals that were OVAL!!! I don't want to get an Intake manifold that is porous.

I was an Automotive Dealer Partsman for Nissan for over 17 years ( 23 years total including Chrysler and Honda) . I ordered parts for the shop, and delt constantly with jobbers for supplying parts. The amount of " garbage " that stated to come out from " off shore " mfgs in the early 90's was unbelievable. I finally told my supplers..If it's made in Taiwan or Thailand...don't even bother sending it because it's going right back. The quality from these two countries was terrible.

Copiers spent little on R&D...they leave that up to the end user!!! Quality control is also very suspect ( I'm talking off shore companies here...specifically, Thailand , Taiwan , China and now Mexico ). If you want snappy little quotes, I'll give you another. No flame intended....

Ya gets what ya pay's for ....

foney_email

that is why I went with the edelbrock.

Time and time again I have realized that you get what you pay for...

Way to say it chickenman 35!! I'm with you, too many knock-offs out there taking away from the companies that do all the r+d. As you said in the end, "you get what you pay for " will be true more often than not, that's for sure. I tried some cheap imitations on a couple of things and when it was all said and done, the parts ended up in the trash and spent the money to get the good parts. There's another saying, "you can pay me now, or pay me later" and when that happens you spent more than if you bought it in the first place, since you have to replace the junk you bought in the beginning.

I have a Professional Products CrossWind intake right in front of me now. (vortec version)
I have owned the Edelbrock RPM before. Good intake.
The quality is good on the Crosswind. They are made in China, not Taiwain. they do not claim it to be a copy or a RPM or anything else. there are specific differences in the design and manufacturing method and materials that make it unique.
Like permanant steel molds instead of sand cast molds.
The Edelbrock manifold is over priced but has been coming down since the introduction of this competitor.
Edelbrock will not go broke.
Competition is good for the Market place and for overall quality.

They do not infringe in any current registered patents.
Their new Hurricane single plane race manifold is a winner.
Both in price, quality and horsepower.
But it sort of looks like a Dart intake at first glance. But its different. And for the price of 1 you can take it home and carve it up to suite your combination and go faster for less.

The first thing Edelbrock did when the L-31 vortec and fastburn heads became popular was copy the design (E-Tec 170 and 200.)

The Protopline Vortec 906 heads are a knock offs of the GM vortec
head. Only better.
Now Brodix has their versions of vortec heads.
The Edelbrock carb is a copy of a Carter AFB. The Demon carb is a knockoff of a holley. A proform carb is a knock off of a holley HP series carb.
Could go on and on.

But I guess we shouldn't consider buying those choices either.
I will agree some of the off shore stuff sucks.
And some of the stuff made in the good old USA and Canada sucks too.

But this stuff is a good buy and a good alternative.

I've been riding the Turnip Truck for quite a while and call 'em like I see 'em. and seem lots of Junk and good stuff out of Edelbrock in the past.
The stuff from Professional Products deserves consideration especially if you're on a budget.

All the David Vizard books were written before these manifolds entered the market place.

You can bet this stuff will get honerable mention in any new books on building powerful engines on a budget.
