Adjustable Restrictor Plate

We tested the adj. res. plate this past Sunday. We started @ 6.90 (1/8th mile) full open. At half closed we went 6.97, 3/4 closed 7.12 & full closed 7.18. Basically the plate slowed us 3 tenths. We were hoping for about 5 tenths. This will be great for some of our index racing dail-in. The products show to be well made. Thanks Donald Powell Donald Powell
