Performer RPM intake?

-
what carb do you run? How thick is your air filter and do you have a drop base air cleaner?
Thanks

I use a K&N 14" x 4" filter, the air pan is fiberglass and sits almost level with the top of a Quick Fuel carb.

#2HOLLEY STREET DOMINATOR

#3CLASSIC EDELBROCK DP4B

#4 EDELBROCK PERFORMER 383

Above shows the intakes rated on highest peak averages. At first I was surprised but after considering the designs on the intake this pretty much makes sense. I'm definitely not surprised about the performer RPM being #1.
 
Interesting to say the least. When comparing the averages of the Edelbrock manifolds in the
important 2,500 - 4,500 RPM segment where most do the majority of their driving they look
like this:

Performer: 427 lb-ft, 288 hp

Performer RPM: 424 lb-ft, 287 hp

Classic Edelbrock DP4B: 429 lb-ft, 289 hp

Naturally, if you are just looking at "drag strip" performance, the criteria is a little different.
Although the RPM is King up on top, it is in last place in the "street driving" segment but there
is so little difference it is of almost no consequence.

In the widest average rev range, 2,500-6,000, still not much of a discernible difference:

EDELBROCK PERFORMER 383
Average 2,500-6,000: 422 lb-ft, 341 hp

EDELBROCK PERFORMER RPM 383
Average 2,500-6,000: 425 lb-ft, 346 hp

CLASSIC EDELBROCK DP4B
Average 2,500-6,000: 424 lb-ft, 344 hp

----------------------------------------------------------------------------------------------------------------------

Only in the upper 4,500-6,000 range does the RPM enjoy a small measurable advantage:

EDELBROCK PERFORMER 383
Average 4,500-6,000: 415 lb-ft, 413 hp

Average 4,500-6,000: 428 lb-ft, 426 hp

hmm, looks to me that the holley SD comes in last all around compared to all 3 of the edelbrocks?? looks like i need that dp4b..

That being said, under light throttle cruising conditions it really doesn't matter. When you put the hammer down you'll be in that 3500+ range where the RPM makes a difference worth talking about.
 
My 440 on the dyno with Edelbrock Performer RPM made it highest torque 535FT LBS at 4200 RPMs and dropped down to 432 FT LBS at 6000 RPMs My highest HP was at 5600 RPMs of 500.1. Now that also dependes on how your motor is built, cam, compression, ect.. Remember this is a dual plane raised intake not a single plane. It runs great on the street and strip. Just a little info on the Edelbrock RPM on my experience with it.

Mine made 514 @3900, 467@5600
 
I had a DP4B on my 383 RR back in the day and it was killer. Best change
I ever made to the car (Sig Erson 284-484, Doug's headers, Mallory dist).

You can find them on eBay but used ones in good condition usually cost as
much or more than a new Performer or Performer RPM and rightfully so.

I don't know why they didn't just reissue them in place of the regular Performer
(or would they just be too close to the Performer RPM in performance?).

That said and hood clearance permitting, I'll probably get a Performer RPM for
my 400/470 build.

Heck i dont know which one to get. I want the RPM but i do know it will not clear the hood, so im left with a decision choosing between the rest..Lots of people have said the regular performer is a door stop for some reason..yet they praise the street dominator but the performers numbers look better than the dominators..?If im gonna go through the trouble of changing the intake, i want the best i can get that will fit in there..
 
The 'old' Edelbrock Dual-Plane

The Way To Go.

The best performing street intake, with 'no' clearance problems.

They are available on E-Bay.

I bought one for $85.00

Which one, the regular performer or dp4b?
 
Edelbrock Intake Manifolds

Old School

#DP-4B {361 ~ 383 ~ 400}

#CH-4B {413 ~ 426 ~ 440}

Either one will 'dance' all over an Edelbrock Performer. There an easy 2/10's
quicker in the Quarter-Mile.
 
i already got a performer rpm on my 400 B so if it dont fit i'm gonna use a shoehorn or get a 1 FOOT drop base or sawzall or whatever it takes lol

Little brother (Weeb) has a 446" wedge in his '72 Duster with pocket-ported 452 heads, Comp Cam,
Edelbrock 750 cfm carb, CPPA headers, 2600 stall B+M Holeshot converter and 3.23 (was 3.55) gears.

It originally had the Holley Street Dominator intake (pictured) but the only change he made during a
freshen-up was to install the regular Performer instead (Performer RPM too tall unless he were to run
his 6-Pack hood).

He definitely likes the regular Performer better. It's a lot crisper and torquier in the lower to mid ranges
where you spend a lot of time doing actual driving; no noticable detriment on the top end.

His new motor with H-beam rods and 440 Source aluminum heads is on the stand and he wants to buy
another regular Performer intake for it.

Man! That's a great deal! I would like to find a nice unsullied one for my 400/470 project.
 
well one option i may have to go with is a 2" high air filter with one of those fancy filter tops

66-3000P.jpg


according to the calc on their site, i need
affform1.gif


400 cid X 6000 (max rpm) / 20,839

or 115 square inches

for a 2" high X 14" diameter filter, the area is
determined by multiplying the diameter of the filter times Pi (3.1416) times the height of the air filter in inches, then subtracting .75-inch. We subtract .75-inch to compensate for the rubber seals on each end of the element and the filter material near them since very little air flows through this area.

so that is 14 X 3.14 X 1.25 or = 55 sq in
so if i use the fancy lid, 14" that will give me (i'm calcing off 13" not counting the edge part) another 3.14 X 6.5 X 6.5 or another 133 sq inches

so i will have a total of 188 square inches even if i just use a 2" filter if i get the fancy top, i get way more square inches than i need

how's that for a sledge hammer lol

i really dont want a hood scoop. they look cool but this car will be driven and i dont want water problems
 
ok, but will the CH4B (RB Block ) be every bit as good as the DP4B (B block) that was tested in the article above? The runner length and other things will be a little different..? I got to make a decision..I guess i should have asked whats the best performing RB intake out there minus the performer RPM or anything else that tall..
 
i already got a performer rpm on my 400 B so if it dont fit i'm gonna use a shoehorn or get a 1 FOOT drop base or sawzall or whatever it takes lol

What car? I have one on a 400/470" in my '69 B'cuda with a flat hood and a drop base air cleaner using a K&N filter top.....works just fine. You will need a taller tthrottle cable bracket though...I used the one from Mancini made by AR engineering...fits perfect.
 
my 400B is sitting in a '74 duster with HDK. will check soon it looks like it's going to be a close call with the performer rpm. gotta get the hood painted and attached first.
 
The original bore 383 I just save from the scrapper( yes, someone was gonna junk it for scrap) has a mint dp4b on it. They were a popular over the counter mod back in the day. For good reason, they flat out worked on the street!
