Diaper required at Division 1 Tracks?

[david ring]

In comp we have a choice between a diaper and a belly pan-we use belly pans on our cars since they are so much easier-I don't know if you could build a belly pan to fit the frames of a stocker or super stocker, but if you could, see if the track would accept them as an alternative to a diaper.

Since Hagerstown MD (Mason-Dixon Dragway) is the only NHRA Division 1 track we currently race at with our series, I sent an e-mail to Elmer (track owner) about the diaper issue. That NHRA does not yet require diapers on most Sportsman (S/SS and .90 cars), and as such, would we (S/SS) get a pass for the Lee Sherman S/SS Race in November? My e-mail first, and Elmer's replies:

"Hi Elmer. I had a question, that was brought up on a racing messageboard for Stock/Super Stock racing. It was stated that NHRA DIvision 1 is requiring an engine diaper/containment device on all 9.99 and quicker bracket cars. NHRA has, however, not mandated them for NHRA Sportsman racers at Division 1 Nat'l Opens, LODRS Divisional Events or National Events. So, would the S/SS cars competing at the Lee Sherman race in November be required to have a diaper to compete there? Diapers run up to $500, and I don't know how many of the 12 or so 9 second racers we would have in November,would want to pay that much to only need it once or twice a year. Thanks."

Elmer's two replies:

"Under current rules if operating as a stock or super stock event , bracket rules would not apply"

and a few minutes later:

"Also keep in mind that there is no certification or spec on what is a engine diaper it could be a metal tray with a pamper in it. I think you will find this to be true. The rule was put I place more for track oil downs than for other reasons in my opinion. However any thing that keeps oil off the track and from under the tires of a race car can't be a bad thing."

So, for the 10-12 Class cars that run in the 9's that we would get, it looks like you will be OK for the two S/SS races we'll have in November.

Hope this helps...I know several people here (Larry, Larry, Dan and Jeff) participated at H-town last November. So it looks like you will be OK for this year. Thought it appears for a normal weekly test and tune, you will need an oil-containment device.

I think I have a little more than $169.00 invested. I had to make some rather extensive mods for the diaper to perform properly, but I am glad I did it. Athey race cars did it, actually, I don't have the ability or know how to do any of this. Custom billet oil filter remote, etc.
