Edelbrock Pro Flo XT

[6872n73]

Has/Does anyone have any dyno results of Edelbrock Pro Flow ET EFI manifold vs a single plane manifold?

I see a few people have used them because of fitment or appearance but I have not seen any dyno comparisons.

Runner length has to have some sort of impact, but how much?

No Dyno results, but drivability sure improved over a Standard 4BBL intake and Carb.

Same here.

Same here.

And I blame this guy for my Pro-Flo 4 obsession..

Engine masters tried to document/ dyno the difference between carb/ efi HP and concluded that the carb made more power due to the fuel cooling the port walls... it was enlightening , but not surprising. A well tuned efi should have way nicer driveability though

Your point here is not clear.
Care to elaborate?

I agree drivability is going to better with the pro flo but some of that is EFI.
Dual plane or single plane - Carb vs tbi - the carb will have more max power every time, that's well documented.
I'm would like to see if anyone has done A to B comparison: ie; ran a pro flo or single plane and then installed the pro flo XT on the same base engine, heads, cam ect.
Edelbrock has a video on youtube with a lot of music and numbers with no specs and a wonky torque curve.

Engine Masters where are you?
