restrictor plate

I need to slow my car a bit to put it back into the 10's. Tech. found a few bars to thin on the sonic check. It could take a while to get the cage to spec. Any one tried the EZ Plate system. If I pull out about 5 or 6 tenths off the ET I could finish out season before the modifications on the cage.

If you have tried to get your roll bar certified by a NHRA official they normally will red flag your car and will not let you race it until it is fixed ...unless your track will turn a "blind" eye.As far as slowing your car down here is a simple little adjustable spacer I made to slow mine down.good luck...hope you can finish your season.

This is how I slow my car down to run the 10.0 class
mounts int the hole on the base and the carb mounting stud

Last year I tried restrictive air cleaner, Pulled timing and ran a small carb. Consistancy was all over the place. I wanted to liscense and let'er run. Thats How I found the cage problem on chassis certification. Back to 10's and it's business as usual. 2 of the sb chebby guys are doing well with the ez plate system @ our track.
