Yeah, I drank the Power Plate Koolaid.

In retrospect it might not have been necessary in a pressurized plenum where the valve and valve events would have dictated flow.  In the boosted LS world there are lots of common plenum intakes, even the Mid-Rise on our TBSS is a dual quad dual plane, and there are no known cylinder distribution issues.

That said, I never changed a head gasket in my Buick.

I thought William and others were working on the "appliance user's" version.

I just had an interesting epiphany about the power plate....

Since Jason noticed a fairly specific trend with how the ports flow relative to each other, it seems that you could go without the plate by using a ''mismatched'' set of injectors.   Sorta like putting staggerd tires on a NECKCAR.

If you take the weakest flowing hole (odds are #1) and use that as a baseline starting with the  worst flowing injector.   If the next port flows 3% more, use a 3% higher flowing injector, etc...    That would allow for the mixture to be more consistent like the idea for the PP, while still maintaining a decent plenum volume for the runners to pull from.

I'm trying to remember the flow discrepancies when Jason published the numbers. It seems like it was 13% was the largest difference.   The trick would be to have an injector bench and some injectors with piss poor QC.

Earl, that is what we all discussed years ago.  Back cylinders get the most flow, so put the bigger injectors back there.  Have you had a lack of sex this spring?

There's never enough.

I get that you put the highest flowing injectors in the back.  But the difference in flow front to back isn't the same amount as the flow differences between ports.

Be easier to spend the $$$ for the plate. Our inj are flowed an go in a certain cly. We have egt readings in every cyl.

A lot of broken parts does not make you a racer; it makes you a slow learner.
