Engine diapers on S/SS?

[jmcarter]

Tony, is your diaper a custom made piece that retains the SFI certification? I know from long past experience trying to fit a TCI aluminum shield on a 727 in a Duster that some creativity is sometimes required. Asking for a friend....

And I agree that Super Street is far from entry and is one of the most entertaining and diverse (well, except for Comp of course) classes. Witness Nick Vogelsang‘s recent slaying of all comers in D3. 50 mph finish line speed differential is remarkable. Recall long ago when NHRA enacted the “Scotty Rule” and how the class has changed since those days. Fletcher winning his 100th in their Super Street Nova speaks volumes.

Sportsman racers are not required to have SFI-certified diapers; they must only be NHRA-accepted. Never has a tech person really inspected the diaper on either of my cars to ensure that it was a particular "accepted" brand or type.

With that said, I do believe that the custom DRE diaper on my Nova is SFI-certified. The universal-style diaper on my dragster is not SFI-certified.
