I bought a edel. performer rpm intake 2 years ago and don't watched if it's a egr or non egr model Any way to know and what happen if I put egr on non egr?? In replacement of the egr spacer should I put a spacer any way or I can sit the carb directly on the intake??? Thanks David
The Performer RPM is a non-EGR piece. DM is correct about the 289 vs. 302 but I don't remember there ever being an EGR manifold in the RPM series. The RPM version is a little taller and can sustain higher RPM's thus the name. It's still a dual plane. I have a regular Performer 289 and I think it's rated up to 5500. The RPM version is adequate for flow up to 6500 or so, but is a little slower off idle. Seth
i have an edelbrock performer intake and it isnt a EGR intake.... it was for a 302.... i bought it through summit racing.... well lets just say i remember it did not say EGR on it
only if you want to run the EGR. you can run it without it just make sure you plug up the vacume line.
I read somewhere that's better to put a spacer between intake and carb that it's give a bit more power cuz of better mix of gas and air does someone can confirm this??? or it's just in my dream zzzz
i have a 2 inch spacer....and it helps with the throttle response....it seems to dog when it doesnt have the spacer.....when i first put it on i thought i would have hood clearance issues...but the 2 inch spacer......the carb and thena 3 inch tall K&N filter fits with about 1/4-1/2 " clearance
You don't need a spacer (unless you want one). The Performer is taller than the stock intake manifold (including the stock 4-barrel intake) so the height of the carb will be the same on the Performer without a spacer as it was on the stock manifold with the EGR spacer...
My friend has a preformer RPM intake and he doesn't have an EGR spacer. Just plop the carb right over the intake. I have an 289 performer intake, and its a non-EGR. I like the 289, really good throttle responce out of it. I also have a 390CFM 4barrel Holley. So its a good setup in my opinion. I just need to put on my quick change secondary kit, and tune it up a bit and it'll be perfect.
a one inch open spacer helped a bit on my Edel Performer 289 intake. Everything just felt a bit smoother, top end improved a tad. Not everyone would notice, very subtle difference.
here a good article I found Under what circumstances should a carb spacer or divider plate be used? Spacers and plenum dividers provide an easy way to change the configuration of the intake tract and the relationship it has with the carburetor. Adding a plenum divider to an open plenum manifold will help keep the left to right fuel distribution balanced for oval track applications when the car is in the corners. This is especially helpful on alcohol engines. These dividers usually do not have a measured effect on torque or horsepower. Using spacers between the carburetor and intake manifold can produce dramatic results. The use of a four hole spacer can improve low end to mid-range power by helping the carburetor draw and atomize fuel. An open center spacer increases the plenum area and can benefit the mid-range and upper rpm power. It is not uncommon to see combinations of spacer types or stacking of similar type spacers. The actual results from any spacer or combination of spacers can only be measured during a test and tune session on the specific engine combination being run. This information can be a very useful tool when tuning to find the best horsepower or to change the power characteristics to suit a specific track condition
The use of a four hole spacer can improve low end to mid-range power by helping the carburetor draw and atomize fuel. thats what i have...the 4 hole spacer and it is a black plastic phenolic material....and i swear that it helps....i drove the car without it and with it...and it is still on the car...
My open spacer got rid of a slight stumble at idle. I think the added height making the overall intake track a little longer may help on low end as well.
story of a spacer or two when i built, i bolted the edlebrock 600 right to the performer 289 intake. result to hot boiling fuel flooding, aka a mess added open 1" spacer. result, fixed carb heating, helped EXTREAM topend, bottom-end and mid-range suffered HORRIBLY. removed open spacer, replaced with 1" phenolic 4 hole. LIFE IS GOOD.:evilsmile just my experience, probably depends alot on the motor config, cam, timing, etc. anyone need an open 1" phenolic spacer.
