I just received my new Adjustable Restrictor Plate. I have a good friend that has been running this same product on his ThunderBolt all year.His car will run 9.90 wide open but that is NOT fast enuf for what is termed "C-Gas" here in California which is 9.60 heads up racing....so he slows it down to 10.60, which is "D-Gas". By using the dial indicator as the measuring device he turns the hexes on the end of the plate with a 1/2" socket which in turns moves the "slides" horizontally to close off the openings to the intake manifold. The carb still runs wide open but the air/fuel mixture is cut back and therefore reduces the horsepower and slows the car down. He has his setup dialed in almost perfectly and with the use of his restrictor plate adjusment and tire pressure he runs between 10.60 and 10.65 about every run.
I am going to use mine to cut the horsepower back so I can "save" my 8 3/4 rear end until I can get the money for a DANA. If my car will run 10.60 or 10.70 wide open then I will use the restrictor plate to cut the air/fuel to reduce the horsepower and dial into "E-Gas" which is 11.60 heads up racing. I can then also set the plate adjustment to run, let's s ay 11.20/11.30 or whatever and run just straight bracket racing....all in an effort to not take a chance of blowing out my 8 3/4.
I will make a few wide open passes, of course, just to see if I can get into the 10.60/10.70 range.
