The ad I was looking at on this product seemed to make some great claims. ( Thompson Performance, LLC  So I was wondering if any out there have tried this product out? And if so what where the results?

I installed them on both the front and rear of a 750 4160 Holley on our dirt 1/2 mile 422” engine. Since no dyno time was involved the hp with them I don’t know if there was an increase. I can say there was never a stumble with them. We recently changed to an 850 and I didn’t move them over yet.

I think it is a gimmick at worst but possibly better in certain scenarios at best.
If feathering out the accelerator pump shot does actually help, then it would only be scenarios where there is a constant fluctuation of throttle is in play, perhaps on a road course, maybe heavy city driving.
It looks like it may obstruct airflow through the carb, which would affect top end and WOT scenarios negatively and may affect lower rpm performance.
I looked for reviews but found nothing with substance. They all amount to I installed this, the engine runs, performance is good. That tells us nothing without a comparison. How did it run before and how has the addition of this item affected that? Ideally, this comparison needs to be done by someone with a more scientifically minded approach and who actually knows how to tune things but some sort of comparison is better than none at all.
One thing that is certain, you cannot trust what a manufacturer says about their own product.
If you have the money, try it but it is a lot of money to spend for potentially no benefit.

Charlie is right and I did it on my sons engine because its driven between 4500-7000 on and off the throttle 6-7 times per lap. At low speed it’s just keeping the squirt of fuel on the edge and possibly breaking it up better. Nothing more.
