You are right about it not having to be SFI approved for most classes (classes requiring SFI diapers are spelled out in the rule book under class requirements) but it does have to be NHRA approved, (list can be found on nhraracer.com )So your homemade diaper idea will not fly.

I understand the issues w/the S/SS cars fitting them in tight quarters and not an easy on and off. But I cant say enough about the benefit of having one . Unfortunately I've tested them both in my S/G car and my TS car over the past 2 seasons. Both incidents happened on top end around 1000'. Both engine failures were huge, rods thru the pan, and in the TS car I broke the block. The diapers both held 95% of the oil (very minimal cleanup for the crews) and all the pieces of block and rods were in them. Both times I was able to stop the car safely, and park it out of the groove. These $200 items saved my cars and possibly my life.
Just my .02

To reply to your quote about not allowing self-made diapers, below is the exact wording from a local track regarding what is required.

"CARS & DRAGSTERS
7.50-9.99 Oil Retention device must be employed Can be self made or purchased online (no SFI rating at this time)"
