Anyone use them?

Do they help?

What pilot did you go to?

Thanks,

Never have but it is always something I wanted to try, the theory makes sense. We run kart or 120 engines on the dyno all the time and you can see the problem very clearly from that.

Two years ago we bought some bar stock to make them for 38's, unfortunately, its still sitting on a shelf

It makes good common sense. If you try them let us know how they work..
