edelbrock intake question
While shopping for a intake for my jeep I keep seeing this info along with
the edelbrock ads: Dual Plane, single four barrel - off idle to 4000 RPM What exactly does the dual plane and the rpm range mean? -- _____________________ HomeBrewer 85CJ7 (in Progress) http://85cj7.blogspot.com/ 99XJ Sport Remove the xxx to reply! |

The RPM range is the recommended power range for the manifold. For a Jeep or other off road vehicle, the low RPM similar to the range you specified will provide better low end "grunt" for towing, climbing, etc. It will also provide better throttle response. The low RPM manifolds like this are always a dual plane design, with long runners having a small cross sectional area. This keeps the air speed inside the manifold higher, which is what provides the throttle response and torque. The RPM range does not mean that the engine will not rev past 4000 RPM, but the manifold will not be operating at maximum efficiency at this point. A single plane manifold has a single opening under the carb which feeds all the cylinders. A dual plane has a divider which in essence splits the carburetor in half. The right half of the carb usually feeds the left bank of cylinders, and vice versa. This allows for longer runners, as well as a smaller plenum volume. The two traits are what helps a manifold improve low RPM engine efficiency. HTH Chris |

Re: edelbrock intake question
The dual plane divides the carburetor in half and the right side
will feed the left head, and left venturi than feeds the right head, you may just see the bottom of the right side and not the side closest that runs underneath: http://www.gmgoodwrench.com/perfpart...3406_large.jpg The advantage is the runners are longer for low RPM that ram compresses the mixture for that cylinder waiting for the intake valve to open. The other type is just an open box with equally length runners compressing their charge at a much higher RPM: http://www.gmgoodwrench.com/perfpart...6822_large.jpg God Bless America, ßill O|||||||O mailto:-------------------- http://www.----------.com/ HomeBrewer wrote: > > While shopping for a intake for my jeep I keep seeing this info along with > the edelbrock ads: Dual Plane, single four barrel - off idle to 4000 RPM > > What exactly does the dual plane and the rpm range mean? > > -- > _____________________ > HomeBrewer > 85CJ7 (in Progress) > http://85cj7.blogspot.com/ > 99XJ Sport > Remove the xxx to reply! |

Re: edelbrock intake question
The dual plane refers to the plenum of the intake (big hole where the carb
mounts). A dual plane intake has a divider that splits the hole into two sections. Edelbrock has several (Dual plane, Single plane, and air gap). They all make your engine produce hp and torque at different rpm ranges. The one you want for your Jeep is most likely the Edelbrock Performer Dual Plane. It should produce the best hp and torque from idle to 4000rpm like you stated. That's the one I have and I really like it. I also purchased the cam that goes with it. I've just recently installed the Holley Projection Fuel Injection kit in my CJ and would highly recommend it. The carb setup I had before gave me all kinds of problems when off road. I don't have to worry about stalling anymore. The fuel injection combined with the Edelbrock intake and cam are a great combination. Hope I answered your question. I'm pretty sure this is correct info. I'm sure someone will chime in if I've made a mistake.

Re: edelbrock intake question
No problem. As for the fuel injection kit you can get a new one from Jegs
or Summit Racing and I think they want around $750-$800. I can't remember. Believe it or not, Advance Auto Parts actually had the least expensive price that I found while researching it. I bought a used one on Ebay for $500. It had never been installed and all parts were still in the sealed containers. It took a while but if you are not in a hurry and want to save a little $ then Ebay is the way to go. They usually have 4 or 5 for sale each week. The first time you go wheelin' with a carb and the trail gets a bit rough while climbing you'll wish you had fuel injection. I had an Edelbrock 600 cfm carb with the spring loaded needle and seat and it didn't work at all. Everytime I tried to climb a hill with a few bumps it stalled at the worst time. Anyway, sorry for the rambling. Good luck and let me know if you have any questions.
