New Jeep Pro-Flo 4 From Edelbrock

[StretchinPA]

They are available NOW !!!!

I just checked inventory and we have (5) systems left on the shelf.

We also have the EFI intake by itself #28115 for those who want to piece together their own EFI system.

Do you have a part number for a kit without the tablet?

I just got mine from summit racing last week. It looks like a nice system but there are a couple of small issues. It doesn't include a fuel deliver system like the original Pro-Flo system did so you have to get their package, $483 at summit or make your own. Their is no baffle under the intake manifold to stop the oil from entering the PCV valve and the intake manifold gaskets that are included just cover between the intake manifold and the heads leaving the lifter area exposed. AMC used a metal pan gasket type that I think you have to use.

Several companies make fuel delivery systems, or you can piece together your own with a good high pressure pump inside the tank and a return line through the OE sending unit. Much safer then running a fuel sump under the hood!!

The intake manifold has provisions (boss's) to install the OE PCV baffle (off of a stock intake) to the underside of the EFI intake. And yes, you should use the OE style metal valley intake gasket

Has anyone installed this thing in their FSJ? Curious about the height and if there are clearance issues. And of course curious about the install/performance!

Looks awesome and with timing control out of the box makes me second guess getting a Sniper and also getting Hyperspark. But am wondering about the height - saw some folks who had issues but they may have been in AMC cars. Just want to make sure I can close my hood.

If you're on Facebook this guy has it installed.

Interesting claim... particularly in light of the fact that Edelbrock was one of the first companies to bring one to market. Any data to support?

Me, I prefer to go the "unsafe" route instead of starving my high pressure fuel pump when I slosh gas away from the pickup at under 1/3 tank.

I'll go out on a limb here...
He is simply stating the fact that any fuel sump mounted under the hood of an FSJ is not as safe as an in-tank pump.
These things crumple up like a beer car in an accident.
Obviously having a large container of fuel under the hood isn't as safe.

You are 100% correct babywag!!!

Just because we make fuel sumps doesn't mean that is the best way to go. I do know that I would never put a plastic container of fuel and a high pressure fuel pump under the hood of my own car (no mater who makes the fuel sump)when it's more efficient and safer to have all the fuel and the high pressure fuel pump inside the fuel tank.

lol
I sure wouldn't even put a metal one after seeing first hand what happened with a ~35ish MPH crash did on mine recently.

Does s anyone else have experience with this? Was going to pull the trigger on Holley Sniper EFI Returnless Self-Tuning Fuel Injection Systems 550-511D but this is making me wonder..

I did some research on it and build quality was a little suspect since it's early. The individual injectors can lead to more precise metering and slightly more power (but more fail points?), but it's an expensive system when considering you still need a fuel pump setup beyond the dizzy and intake included with this system. The tuning interface looks top notch though.

I figure both Holley and Howell have similar products, and only Howell is 50-state approved.

I'm still looking at the best option too though, since at some point I'll want to delete the stock dizzy, the carb, possibly the EGR (if I can -- smog requirements??), and of course go with a better breathing intake and 4bbl-type set up and coil for increased power.

At some point I'll make an excel sheet listing all my needs, what each kit offers, and what else I'll need to piece together for a full-on EFI, intake, dizzy, coil, and fuel pump set up.

One point that nobody has mentioned yet: the intake manifold is a Victor Jr single-plane design which typically has an operating RPM range of 3500-8000 RPM. It's absolutely the wrong manifold for the 1500-5000 RPM range we need power in.

The same kit built on a Performer manifold pattern would be far more suitable. Sales volume would obviously be minimal, so it will never happen, but it would be far better for Jeep/truck use.

Better yet would be a manifold actually designed for use with EFI instead of a carburetor manifold with injector bungs scabbed in. You know, something like an OEM intake manifold - they look nothing like a carburetor manifold because they aren't designed around a carburetor-style throttle body. Consequently, they work a lot better at making power at real-world speeds.
Cost would be significant and sales would be zero, but it would be fun to build. And by "fun", I mean a gigantic pain in the hinder.

Not trying to rain on anyone's parade here - just want to make sure people know what they are looking at.

correct. however, keep in mind this is now a "dry" intake,and thus air velocity thru the carb to maintain fuel shear and atomization and fuel suspension is no longer a factor. air velocitythru the carb is one of - but not the only-factors for a dual plane intake.



while intake runner design does indeed affect power band,i think this intake will be far more forgiving operating as a port injection unit.

Anyone running one now? What are the results?

Sort of. We are just finishing one up right now. It does run nice.
