so I ordered the Thompson performance powerblast plates for my 4150hp. Anyone have any testimonies
When Holley puts them in all of their carburetors, I'll pay attention.
Exactly. I'll pay $90 for a shot Try them outThat's one of the reasons why I tried it out. And it did seem to help. I also found that my secondaries were occasionally hanging open just the slightest bit
won't ask you to out the crap filter, but which ones have you tried that work?We tested a 427 CID engine the other day in a cell, and were able to KILL 50 HP with a certain type of air filter assembly. We have a customer in the field with the same air cleaner saying it "feels better" "feelings" aren't always what they seem!
In very general terms, Foam is junk. it neither cleans the air, or flows well.won't ask you to out the crap filter, but which ones have you tried that work?
it Seems logical, but i can never understand why things like this simply aren't marketed with 3 or 4 different engines, or vehicles, strapped to a dyno with "amazing" results. a 4 min video, and it either rides or dies.

Simple. That's because stuff like this is snake oil. Always easy to spot because there's never empirical data to back anything up. Comparing before and after videos of someone revving the engine is subjective, as anyone could rev the engine slower or faster to easily show a difference. To me, the bottom line is this. If these things were"tits" they'd be on every single production Holley style carburetor built. They're not. So for me, nuff said.
I get it. Your right. I’m not by any means a pro at any of this stuff. I do notice a lot crisper throttle response and ..... more grunt when it’s under that initial load when I punch it. Maybe it’s a mental thing . It always feels like it’s faster after you do anything to it that’s how you justify spending more moneySimple. That's because stuff like this is snake oil.
