I have been informed by several racers that it is getting down to the last minute on getting the 1 7/8 injector retrictors. I had originally hoped that everyone would be able to purchase their restrictors from ITI . The ITI restrictors will be Hard anodized in Black and have USAC etched in them. They will be the easiest to tech. I want to make sure everyone has them by March 6th for our race at Thunderbowl Raceway.

 Steve Faria will also build them. The phone number to System 1 is 559-687-1955
