Engine diapers on S/SS?

Steve, I don't have a rule book, but are you saying that S/ST, the entry level class, where the index is only 10.90, requires a diaper?

Correct...that and the flywheel shield were the only two things I had to add to the car for S/ST. I know a lot of tracks were requiring a diaper on Sub-10 second cars as well for their weekly bracket programs. I don't know if I needed the flywheel shield though as the car runs less than 135 mph?

I don't think the diaper should be mandatory...but it's definitely cheap insurance.

For what it's worth...The rulebook does state that a minimal number of slots or holes to "clear frame, steering, or lines" is permitted.

Well guys, There's a way to address the S/ST issue.
No electronic throttle stops , and a 125 max speed (breakout).
In other words, bring it back to entry level.
But why in the hell would they?
Look what they've allowed to happen to Stock.

Why would you think S/ST is supposed to be entry level?

I only go 12x MPH on 9" radial tires, but I like the diversity of the class just the way it is.

I don't care if Stock and SS are allowed to run without a diaper, but the drag link through the oil pan and close-fitting headers are not issues that would prevent one from being used. As I mentioned in my first post, my diaper has holes for the stock motor mounts and has Kevlar side panels where the headers touch.

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.

Why? Because NHRA promoted it that way originally . Maybe you weren't around back then?
Divisionals only..No nationals
No national points/ champs
No running S/ST and another category at the same event.
In other words, a simple class for local bracket racers who want to try NHRA racing, locally.

Another case where it looks like the inmates are running the asylum.
Only question is..Who are the inmates here?

If Super Street were supposed to be entry-level, I'd have no interest in running it. There is no charity class at a divisional event, nor should there be. Bring your best and hope that it's enough!
