Default Who has dyno testing comparisons of the Victor Jr intake vs LS6 style intake?

I would like to see some graphs posted. PureEvl did the testing but never posted the results?

there is an interesting discussion going on, in the advanced section, but I am interested in the FI results, who cares about NA

FI is a whole different world than NA so flow #'s mean little.

Someday we'll post a graph on differences it's just hard to do with a Turbo setup. Soon we'll do a supercharged car.

A few FI experts basically told me that my Edelbrock single plane will perform as well as my Beck sheetmetal intake, but that the Edelbrock intake should have slightly better AF's across all the cylinders, ie. the back cylinders won't be leaner than the fronts.

Turbo's (well atleast our's) get's the reference of the manifold.If the restriction changes the boost stay's the same. A supercharger will probly show boost changes which a power curve will follow.

From what I've seen personally from it is that we can run a good amount of boost without KR and the plugs are reading even know unlike the rear cylinders leaner than the rest with the LS6 intake.

I guess I'm sort of in a different boat. I have a T-76 that I've maxed out at 21 psi on a 363. I'm working on installing a single plane in place of my ported LT4 but I'm not sure if it will help me. It will do 1 of 3 things:

1. Not help at all.
2. Make more power at lower boost (pump gas) but not max boost.
3. Make more power at all boost levels.

The better flowing the heads and intake the less boost it will make.
