Anyone try Thompson powerblast plate

why wouldn't it like an atomized (fine mist) fuel charge? More surface area, more complete combustion? MPFI...

You make a sound argument with a scientific notation that just doesn’t pan out in real world applications. Hey did some reading on the subject and I can not remember it all to explain it but in a nutshell, it just doesn’t pan out that way.

MPFI is awesome but overall it still makes less top end power than a carb.

WOT where its still using the pump shot is probably not that high, grant you that, but is it still hitting the side of the booster that has a high velocity around it?

Higher velocity when in the rpm range. It is a constant changing variable. If you have enough pump shot for low rpm take offs, then the same amount higher in the rpm range is more than enough if not to much. You only need enough not to stumble while maintaining the desired fuel ratio.
The amount of pump shot injected/used is also a variable between manuals and automatic as well as completely adjustable in a Holley. Lesser on the Carter. It still may need adjusting.

The higher velocity around the booster is always there. It’s always higher than the rest of the Venturi. But that doesn’t mean it is high enough to gobble up and atomize the whole or part pump shot. The velocity may still be slow to do so atomize it all.

over carb misting jet sounds like any TBI....All in the name of emissions and a more complete combustion creates more power per lb of fuel.

At low to mid rpm’s. Excellent for mileage and drivability and emissions. Not all out power potential.

Carburetor powered cars still maintain the highest hp output period.
