Anyone try Thompson powerblast plate

Back to the powerblast plate, I really cannot see how those can effect WOT horsepower production. Really they are on a completely different circuit. The squirters are there to cover up a momentary lean dead spot on tip in right? So on a properly tuned carb set up there is really no power to be gained. Now how can we test drivability? That’s the question here. I can see them making a difference in how the engine reacts on the street in average (there’s that word again Rumble) driving scenarios. Johnny will you be street driving this car at all? I know it’s a bracket car, but any road time?
