We continue to encourage all drivers that race purpose built race cars (not street cars) to consider putting an engine diaper on their car. The IHRA rulebook requires diapers in all of their pro classes plus Top Sportsman, Top Dragster and Quick Rod. Any car that is supercharged or nitrous injected that runs 7.99 or quicker 1/4 or 5.00 or quicker 1/8 mile is also required to have a diaper per IHRA rules.

We feel all racers should consider installing an engine diaper on their car. No one will be turned away at tech if they do not have one, we are just trying to point out the real benefit to every racer. Installing an engine diaper could save your car, it could save you from possible injury or maybe even save your life. It will also save valuable track time for the enjoyment of fellow racers and fans. It will help reduce track expenses for cleanup and the extra time saved from cleanup will allow more cars to go down the track - resulting in earlier event completion. On some Test & Tunes this year (when time permits), we hope to reward pro-active racers by giving a bonus run to those drivers with diapers on their cars.
