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?

Re: Engine diapers on S/SS?
Mark, yes an oil retention device is required in Super Street. Believe it would already be in place but the last time they floated it the heard how much of an impact it would be. Strangely enough bracket cars don’t require, likely because they don’t put the Fuel Circus at risk of losing any track time. I’ve already submitted my impact statement to the SRAC. Have a Stefs pan with hole for the drag link to travel through, custom made headers by REF that come very close to pan in several places. Even if one could be custom made it would come very close to the belt drive. As stated earlier if they hand down the rule as mandatory then current car will no longer run in Super Stock

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. Last edited by Steve Stasko; 10-08-2019 at 11:29 PM. |

Re: Engine diapers on S/SS?
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.

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.

Re: Engine diapers on S/SS?
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.

Re: Engine diapers on S/SS?
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?

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.
