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.

High quality junk here: intro thread and slow build thread

Did you know? Willys is just Willis spelled differently, but pronounced the same. Neither Willy nor his apostrophe are involved.

.




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.
