Jim, Thanks for interpreting!! Yes, I talked to Jeb. Nice guy and very knowledgeable. I think I'm going that route. Is yours based on the Victor or Victor Jr.? I've also looked at a DP, mainly the RPM.

Not using it yet, but here's mine.... another product I stock
It's a PRP Super Hurricane EFI single plane (new on the market). Similar to an Edelbrock Super Victor, but with EFI bungs. A bonus is it comes polished already.

RacerX70cc,
I've noticed that most of these I've seen are the Victor type single plane intake. Is a SP in a an EFI setup usefull at all RPM or are they still confined to the given RPM range in a carburated use? While I think I can guess the answer to that, are there any applications made more for the low-to-mid-range RPM use? Thanks for your help, but I'm interested in learning all I can as this seems like a great alternative
to the miniram or the superram for getting more out of our engines than just 5000 rpm.

From the configuration of the single plane, it is more geared towards midrange and upper RPM operation in a wet application (i.e. carb use). Using one in an EFI application will likely lessen this somewhat, but the affect will not be as dramatic as the intake manifold itself is simply flowing air, and the atomization occurs within the ports, rather than the plenum as with a carburetor. What affect on low-end torque it ultimately has is subject to the camshaft, injector size, etc. and of course, the actual CID of the engine used. Throttle body choice/size should play a part as well. I'd lean more towards a 4-barrel type throttle body, rather than the intake elbow/conventional TB that most everybody else favors, if for nothing more than hood clearance.
The product information for this particular piece states that used as a wet manifold (it comes with plugs for the injector bungs for use with a carburetor), the displacement should be no less than 420 cubic inches. For use with EFI, you can use it with 350 CID and up, as the fuel is not atomized in the plenum.
Myself, i'm going to test it on a "test mule" L98 car (If I ever get the damned bodywork finished), and evaluate its street potential. Some other SP users can chime in with their results, of course.

That is exactly the set up I have been looking for.
I have viewed this forum for years looking for that exact setup. The the plenum made of a composit material? Just wondering since it was painted. What is the plenum called, who makes it and where can I get one?
I suppose It would work with a dual plane intake as well. Mabey now I can sleep at night.
