What intake do you use, and why?

There is so many intakes now it's getting hard to choose, so I thought I would ask you guys what you use and for what reason, and (if you know) how much HP it makes.

Thanks.



:boxing: And no fighting! :nono:

Edelbrock RPM airgap, I chose it because of the separation of the hot engine valley and the air/fuel charge. It makes sense and seems to work very well.

I must say though, it works better in the first 10 minutes the car is running, after that I think the manifold heats up with the rest of the engine anyway.

HP, I don't know, but I can tell you it was a VERY noticable difference over the stock steel intake using an adaptor plate for the Edelbrock carb. I don't know what helped more, eliminating the adaptor plate or the actual manifold swap.

Older Edelbrock Performers on both my 350s. Reason, they were cheap at a swap meet $75 cdn and they have bolt patterns for square bore and spread bore carbs. work just fine for what I want.

I used to think edelbrock made the best performance parts, and I used them on everything. Now I realize that I was probably the victim of edelbrock's advertising budget! Edelbrock advertises more than any other performance parts maker. They're great bolt-on parts, but I don't think they're the best stuff out there. Edelbrock makes "no brainer" parts. Actually their higher end intakes are very nice, but the performer (not the new EPS, not sure about that one) in many tests barely makes any more power than stock cast iron intakes! I'm going to be using a weiand stealth on my 388 motor. It has better hood clearance and a wider RPM range than the RPM performer, and I've heard from reliable sources that its the better intake hands down. Don't get caught up in advertising and hearsay! Edelbrock stuff is good, but its probably NOT the best you can get.

I'm using an OEM Z-28/LT-1 (late 60's, early 70's) aluminum dual-plane hi-rise in my 350. It's always been considered the best of the OEM intakes and has held up well against the aftermarket intakes of similar design. I'm guesstimating around 380 HP or so with my combo. Plus it's nice to see the OEM intake under the hood of my 69 Camaro.

I responded to this same post in another forum. Depends on application. EAdelbrock has some good intake choices, & so do others, just depends on application. My 454 currently has a Edelbrock Performer. When the time comes where I dicide to rebuild it, & up the level a lil more Ill probably use a Wieand Action +. John

Wow, all Edelbrocks so far.

I was thinking the same thing about the Performer manifold, it looks like a stock replacement.
The Weiand Action Plus, Holly HLY-300-38 and the Holly SysteMAX look like stock replacements too. Correct me if I'm wrong.

The Air-Gap intake looks good but I don't really like the opening between the top and bottom plane.

The Weiand Stealth looks like a pretty good intake. Anybody use one?
How about Offenhauser?

And yes I have the same thread going over here ClubHotRod to see which way it goes.

i got an older performer for my 326 i got at a swap meet for cheap $125, okay not that cheap, and it's not on yet either. i have a rpm on my truck, not the right intake for down low torque, but way better for romping on the throttle, even tho my cam quits at 5500 or less. i am planning on using either the stock intake-probably on my current rebuild just so i can say it's all stock and original (72 camaro) or i might use an rpm cause my friend wants to trade me his in exchange for my older torker intake that used to be on my truck when i had a isky 270 cam in it. i also like the stock intake because i dont have any extra carbs and the stock quadrajunk will fit on it. i had a 750 holley (too big) and some other carb, but a "friend"took them to clean them and i havent seen him since and don't think i'm likely too.

i guess they are all edelbrocks mainly cause thats whats around. i guess that's whats around cause they are the cheapest. saw great dyno results in an intake shoot out for the air gap tho, in hrm a couple years back. i've seen a wider range of operating ranges on not only the wiend but the holley intake as well. i think they are both under the same roof now.

I have always used Edelbrock intakes, and they have worked well for me. As far as which one to use, the main thing is that you want to match the powerband of your heads and cam. If you have a stock cam and heads engine, the performer would be a good choice, if you have something that is souped up a little and the cam and heads will like to run in a 1500-6500 powerband, a Performer RPM would be a good choice. If you have something that is going to spend its time in the 3500-8000 range, a victor series would be a good choice. Each intake will make different power on different motors. It is all about creating the right amount of air velocity in your motor; that starts with getting the right size carb and ends at the right size exhaust, it is all about matching the parts.

Professional Products have a line of manifolds similar to Edelbrock's. According to their (PP's) figures, they are better performers than E's and others. The PP's are definely priced better than E's, and the guys using them seem pretty happy with them.

YIKES!!! There's a MAN in my computer!!!!!

Victor, wish it was a sheetmetal tho

I've got a Edelbrock Victor intake on mine. It is kinda laggy at 1500 rpm, but once i get some flow through the carb it screams. Throttle respons off idle is a bit sluggish and i often find myself double pumping the gas when cold, but once im above the 1500, any increase in gas and the thing likes to launch. Then at 3000 rpm, there is another burst of energy thats nice to say the least.
When i change my cam and swap to a manual transmission, im gonna use either the Spider from CHP or the Wilson or AFR ported equivelant to the Victor. I wouldnt mind having a nice blower intake on, especially with an 8-71 sitting on top.

I almost bought a Weiand Stealth Series, but I couldn't find any dyno tests done comparing it with the performer RPM. Almost every magazine uses the Performer RPM in SBC build ups so that was why I went with the Performer RPM, but I saved the receipt. Killer what have you heard that made you go with the Weiand?

I guess I'm different. I know the Edelbrock performer is the standard these days, but I went a little different. I wanted the looks of a single plane manifold, but streetable. I'm using a Wiend single plane that comes with a divider plate that's supposed to make it work like a dual plane. I think its the 7343?
Seems to work good though.
This is an old picture but you can see some of the manifold:

edelbrock performer rpm air-gap is what i'm using

picture

i had purchased a performer on the advice of a local shop owner (who was just wanting to get rid of inventory, but told me that it was the intake i wanted for sure, hands down, couldn't find a better intake :rolleyes: )

After reading a couple years of rodding magazines as well as posting on different forums for a while i realized that the performer wasn't really what i wanted, so i reaserched different available intakes, and asked of a couple forums, and the edelbrock rpm air gap seemed to be the winner, supposed to have the good torque of a dual plane, but have the high rpm usage of a single plane, not sure how true this is or not but it was reccomended by many a racer and engine builder (who may have been victims of edelbrocks marketing budget as posted earlier ;) )

in my research i found it's hard to tell what inakes are good cross companies though since the rpm ranges they work best at are not defined using a universal standard, so saying that the weiand intakes work in a bigger rpm range is not quite true, weiands intakes all have a broader advertized range, where edelbrocks have a smaller advertized range, but probably work as well through the same real world rpms. However this is all speculation, maybe weiand has found a way to make their intakes have a broader range, but i would think that technology would be quickly copied by thier competitors.

well, just like I said before Ghettojet, I use it because its a tried and true manifold that doesn't have to advertise too much to prove its worth! The runners are wide and will work well to make high RPM power, but also the duel-plane design makes it versitle for street use. RPM performers have trouble fitting under the tight hoods of cars like mine, and I think the airgap thing is a gimmic for sure. I doubt its worth the money you spend on it if it does make any difference. I've yet to see numbers for any kind of proof.

On the sleeves chevelle its a factory aluminum oval port intake from a corvette (lowrise) that gave me the best off idle performance, but once I went to a performer rpm with matched cam it woke up! I really think that its more a matter of where the tach needle hangs around that tells you if you have the right setup Too bad they dont market a Dr Jeckyl/Mr Hyde style of manifold. although Offenhouser did market one called a dial a flow with the replaceable center divider insert a decade ago Never got to try it
