Is this Intake for the Vortec heads comparable to The performer RPM, what is it's Rpm range???

http://www.sdpc2000.com/cart.asp?act...d=738&pid=1801

It say "Maximum horsepower with a braod torque range."
I can't find the RPM range.

I think it will out perform the performer intake. That one looks like the street dminator put out by Holley which cost me 150 dollars from Summit part 300-70 and it is vortec bolt pattern compatible.

Oh and the powerband of the dominator is advertised at idle to 7200 and is a nice piece. I have it on my 305

No4NJunk

the RPM is the best on the market right now. Its constantly being tested in mags if you can find one.

Mark A Shields

how does it compare to the weiand stealth do you know?

radiateu2

i highly doubt the magazines perform the tests all they look at is statistics and data and a desktop dyno which doesnt tell the entire story. This is why many refer to it as edelcrap. The Street Dominator has been around a long time. It has proven it self time and time again. Checkout the boards here many people left Edelbrock and went to Weiand or Holley. I chose the Dominator for its powerband the feed back from summit and jegs from there tech department said the Dominator has a slight advantage over Edlebrock off the line and much better lower end torque because of its higherise.

We are talking about VORTEC intakes here.
I don't believe Weiand makes one.

Edelbrock is always used in tests. That doesn't mean they are the best, just that they pay the mags for using their products in the build-ups, GM doesn't really pay the mags for exposure, they don't need it. Anybody who knows a GMPP catalog knows there are a bunch of secrets in there and a lot of times ( since they understand thier own heads and blocks better than most aftermarket producers) the performance parts are better than the aftermarket in terms of OVERALL performance, not just shooting for peak horsepower.

When was the last time you saw mags using GM performance parts??? ( besides the Lt4 hot cam)

Mark A Shields

Didn't realize No4Njunk was talkin about an Edel vortec intake.

No4NJunk

Got one right here in my F*cking hand. They mention more GMPP parts than aftermarket ones. Its an artical in Hod Rod on offset grindings and different displacements for small blocks. If you know how to read then go check it out .

Oh and who in here was the sales rep for edelbrock.....

Oh....you again huh. Well I won't even comment on that remark.

I'll find the magazine where they test holley against edelcrap, as "the profound speaker of all things" above has dubbed them.

Holly owns weiand. They have for a long time. So basically you can just call them holley too. Most if not all there designs are similar.

just because they have been around longer doesn't mean they are better. There are numerous problems with holley products ( such as those damn power valves) that I don't have to worry about with edelbrock. So there have been those who have switched from edel to holley. And I'm sure the inverse of the later has happened also. That doesn't make them any better.

Now The manifold mentioned above may be better. To be honest I don't know. And the one thing I can agree on with 330 is that GM probably has a better handle on things considering they do understand their block and head designs better. So I won't doubt the possibility of There manifold being better. I simply mentioned the RPM was the best on the ( probably should have said "after") market right now.

330hp_91RS

Maybe saying edelbrock ' PAYS' was a bit much, but I just mean that GMPP doesn't really get much exposure on intakes and such but rather heads/blocks. Mags seem to be more inclined to test with the aftermarket cause it seems more accessible, and most people think that the aftermarket= performance.

No4NJunk

I can agree with that.

And yes mark, I was talking about the RPM for vortecs.

radiateu2

weiand does make a Vortec intake its called action plus check it out do your homework. Never claimed to be a sales rep for anyone just listen to the people on here who have these things and feed back I am not starting a flame war here N4NJUNK if you like Edelbrock fine. The question was can the intake in the photo out perform Edlebrock? Oh and those Damn powervalves they have fixed that problem in case you didnt read about it in your magazine articles. BUT your right no conflict of interest with Edelbrock paying for the testing is there. All I will say is do your homework and listen to the people who own different intakes get there feed back, and dont take everything for granted in the articles in magazines. Someone is getting paid to write it and someone is getting paid to test it. Your best source of info is right here with the people who have first hand knowledge and nothing to gain or sell.

First, I'll say I have no clue as to the answer to the original question.

As for magazines, they make their money from advertising. So, they aren't very willing to do comparison tests that might embarrass the source of their income. If you rely on magazines for your technical information, there is a good chance you will be operating on incomplete information.

As for these boards, there is plenty of bias that is completely devoid of factual basis. After all, we're all Chevy guys here, who often get spanked by Fords & Mopars, but won't admit it. Plus, just listen to yourselves in this discussion of Holley and Edelbrock - just a bunch of opinions, without a single number to back any of it up.

You can see from my sig where I've gone. To be honest, I chose the Weiand over Edelbrock because of price and advertised RPM range. I chose the GMPP because it was a take-off being offered to me by a fellow racer at half price. Okay, call me cheap. Both cars run quite satisfactory to me - for now.

Oh, in case you're wondering about the italics, you guys need to learn the difference between there (as in, "He's over there"), and their ("That's just their opinion"). Don't forget they're ("They're going racing next weekend"). You look like morons when you keep using the wrong form.

GilmourD

Ouch... Somebody got spanked. LOL

Anyhow, Gotta back up five7. It's like a pissing match in here. The reason I chose the Edelbrock intake is because it was a few steps up from stock, plus my brother worked at AutoZone at the time and got me a FAT discount. And the reason for the Edel carb is that everything that requires a gasket is mounted vertically, as opposed to Holley's horizontal design. The bowls won't leak when the gaskets go. Plus it's a bit smaller. And it's really a Carter AFB in a really transparent disquise, and they have a pretty decent rep... Oh, yeah. I got it CHEAP!

From what I understand, the reason some people call Edelbrock Edelcrap doesn't have as much to do with a design standpoint, but rather a QC standpoint. Sometimes the stuff comes out of the factory a bit... eh... Ya know? I'm sure that it's no more of a percentage than other companies, but Edelbrock also produces a lot more than other companies, so it has more exposure. In the world of mass manufacture, things get F'ed up a bit sometimes.

CamaroDriver

You got a PHAT discount.

Oh, in case you're wondering about the italics, you guys need to learn the difference between fat (as in, "That guy is fat" fat:being large and jiggly), and phat ("That girl is phat" phat: extremely attractive or impressive). Don't forget "bitch" ("That bitch is phat"). You look like morons when you keep using the wrong form.

:sillylol: :sillylol: :sillylol: :sillylol:

GilmourD

No, I meant fat. As in the condition of the pile of money that I saved due to said discount.

No4NJunk

First off I'd like to say that I'm not here to show off my typing and literature skills. If you think I'm a moron because I got some of my "theres" wrong well then fine. I could give a **** on your opinion. As for a flame war. NO. I'm not trying to start one. As a matter of fact I wasn't even calling you the sales rep radiat!! Go back and reread. I don't get all my technical data from magazines but I do read them AND take what they have to say into consideration.

Everyone came in here after me to state what.....

"Well your wrong"!!

Is that it? I'm confused. I tried to give the guy an opinion (based on backed infromation-whether it was false or not). And everyone else just comes in here to bash edelbrock. WTF. I'm not mad but more surprised at the way you guys are handling this. This guy could give a **** what YOU use. I'm not in here to argue about if they have fixed the power valve problem or not. how about giving me a link to this so I CAN read up?? The point isn't to make me look like a "moron" but to educate me. Thanks for the help . I also never said that weiand never made a vortec intake. So I'm guessing that comment wasn't addressed to me. I do my homework as much as humanly possible. That includes reading, listening to my fellow coworkers who are much older and wiser, and going to the library (I've got a collection now). I take everything said with a grain of salt.

I'm done.

Actually, since this is already under way...

I call it Edelcrock because they have no QC department. 3 water pumps wasted in as many minutes and one very badly cast and machined Edelcrock Performer RPM for SBC manifold is my own personal proof of that. Their tech guy told me all of their water pump bearings are US made. Well, the bearing in the last pump I got, that I still have, says Slovakia on it. He didnt have any answer for that one. Neither did the guy I talked to about my intake. Fortunately before I started modifying it to try and make it fit, I threw a gasket over both sides (previously, I had only checked one side, the side that happened to be ok) and realized the ports and bolt holes didnt line up... at all. And it was wider in the front than the back. POS.

As to the original question, there is a distinct possibility that Edelcrock makes that intake. I cant say for sure, but its very possible. It looks like one. You might want to look into the air gap manifold first. Performance wise? I doubt you'd see any significant difference between two med-rise dual plane intakes of any sort to write home about. Just make sure its machined right before you try and bolt it to your engine, otherwise you'll end up with some tech rep from Edelcrock telling you that your factory LB9 is mismachined and thats why the intake doesnt fit.

330hp_91RS

I just want to know if anyone knows the RPM range on the intake in that link up there. I can get one cheap and I want to replace my Edelbrock Performer.

Enough with the pissing match, please try ta answer my question. I don't know if you guys were saying that edelbrock may make that intake for GMPP ( I might have mis-understood) but if they do then I'm definately gonna go for it cause that is definately a performer RPM.

No4NJunk

330,

Not sure of the rpm range on the above BUT edelbrock (crock, fock, nock or what the f**k ever ending anyone wants to put) has an AIR GAP manifold (same rpm range as the RPM) for the vortec heads. The jegs number is 350-7516 ($219.00) or polished 350-75161 ($329.00) and the RPM vortec intake is 350-7116 ($173.00). If Weiand has one then I can't find it. I just checked the net and all my catalogs. I only knew about the edelbrock and was the reason I stated it being the best right now.

Later

Well if you want an RPM range on that specific manifold, call GMPP. I'd bet a dollar that its the same as the performer RPM though.

The advantage to the air gap is it will run cooler. Thats about it.

I was under the impression that GM carb Vortec manifolds are manufactured by Edelbrock for GM. Could be wrong, though.


P.S.: My apologies for my terse comments earlier. I was tired when I first read this post, and having to think about what a misspelled word is supposed to mean strains my brain and slows down my reading, especially when I'm tired. So, don't take any of the comments personally - they were intended to be general comments (and probably out of line, anyway).

Mark A Shields

I have to give it to you, you are one of the very few stand up guys on this board, you never intend to attack anyone, and if it comes across that way, you apologize.

I'd like to thank you for making this a better site.

jimmy_mac

Ok, so has anyone reading this actually run their car in the quarter mile before and after intake swaps. Like someone who say replaced their stock intake with the performer. Or even going from the performer to the wiend. And what cam and heads where you running.

CowBoy_Racing

F*ck it, I say we take some cars down to carlsbad drag, put stock intake on, run it, then put aftermarket on.... run it and see the differences... or we can just go find some empty street (and get arrested ) but whatever, I say we do our own tests.... atleast 1 person with each type of intake come down sometime and we'll find out which intake actually gives the best performance, then the one that gives best performance for ur buck...... doin ur own tests are the only way to find out if **** is true....


kinda like findin out if your VVT-i TT (ball-bearing 3086 aftermarket) with 3-stage 400shot NOS (5-spd manual) Toyota Supra can really out run the cops or not (some guy down the street from me pulled that **** a few yrs ago... and yes, he got away... til the next morning..... when the po po was there arrestin his ***

jimmy_mac

Oklahoma is kinda far from Carlsbad but if you want to ship me any manifolds you have to test I will gladly put them on my car and run them at the local track. I currently am running a stock alluminum one and have been painfully contemplating whether I should upgrade or not.

CowBoy_Racing

well, for all ya'll not from around San Diego/L.A. Metro, we'll just post results of our 'experiment' on the board, but for those of you around here..... lets get somethin goin where we can test this **** out....

:lala: (sorry, just looked hella funny

330HP_91RS- Check out the GM "Power Catalog" available from your GM dealership. This book normally gives you more than just the regular 'advertised' hoopla. It also gives modification advice on various parts as well. But I think this will be your only source of specific RPM potential.

But as for the GMPP manifold, its basically a copy of the Edelbrock RPM.
