Our friends over at Prestige Motorsports got a customer who sent in a set of Thompson Performance Power Blast Plates, so they set up a video comparison test to see how good these things really are!
In the video, you will see the Thompson Performance Powerblast Plate tests side-by-side. First, the left view shows an initial quick rev test, followed by the same test with the Powerblast Plates installed in the right view. The transition to 3,500 RPM followed by the dyno pull is shown for each view simultaneously.
And what was the result. I saw the difference in spray patterns
Bruce – Check out our blog on the video here for our findings. Thanks for watching and let us know if you have any questions at all. https://www.prestigemoto.com/hardcore-tech/blog/the-money-shot-does-powerblast-plate-really-work.html

The article doesn’t mention it, but what you’re looking for here is better throttle response. The video isn’t totally conclusive or convincing. You want to make sure your carburetor accelerator pump shot is correctly sized for the needs of your vehicle/application. Ideally, you want the smallest squirter size (the orfice) that meets the needs of the engine – this ensures good atomization. Smaller Orfice = Better Atomization. Further tuning can then be done by tuning the duration of the squirt. Tuning kits are available for both Holley accelerator pump adjustment (https://www.speedwaymotors.com/Holley-4150-4160-2300-Carburetor-Accelerator-Pump-Shot-Tuning-Kit,414609.html) and Edelbrock carb accelerator pump adjustment (https://www.speedwaymotors.com/Edelbrock-Performer-Carburetor-Accelerator-Pump-Shot-Tuning-Kit,414613.html).
Agree!
Agree and well said. Once the accelerator pump shot has done its thing, the skirter is just along for the ride and contributes nothing to making power. From a visual standpoint it seems to me the power blast plate would distort airflow over the venturi which may have an effect on air/fuel mixture.
While it may appear that way, our test (which is explained more in depth on our website prestigemoto.com in the blog section) did not show any significant change in air flow (cfm) or air-fuel ratio. Simply a better atomization of fuel during acceleration and transition into secondary circuit along with throttle response.

You are correct about throttle response. That is the main objective of the Powerplate. You can read the meat of the review on our website prestigemoto.com in the blog section.
and the results were?

That’s what I was thinking! Where’s the beef?
