That's pretty good of your track guy to sell them at cost Yes it is and he’s a good friend but look at it this way. He made the rule at our track before the division officially did. It helps both him financially with track cleanups and us for wasted time waiting on cleanups and possible wrecks. Ohhhh ya we be-itched and moaned and some are still skirting the rule but it kicked us guys on the fence to finally put one on. I wish others would

I've heard NHRA will require engine diapers for cars 10:90 and quicker. If so at what point do they have to be sfi? Did you just hear that or did you actually see it somewhere from NHRA? I have the same question.

You do not need an SFI lower containment device until Pro Mod, Alky and Fuel classes. Otherwise you just need a diaper, NOT an SFI one. So in theory you should have zero issues with you expired SFI device.
According to the newest rulebook you do not need one unless you run Advanced ET, S/G, S/C or S/ST and Pro Stock, all non SFI required. Otherwise I don't see anywhere it is required other than those, and the aforementioned pro and alky classes.

Hey Scott I believe your referring to my wreck, yes Im a firm believer in diapers on any modified drag car, I did actually have one on the challenger but it was placed back to cover minor rear main leak,not covering but only third of the block,gonna cost me dearly to restore the wifes challenger, I had one on my daytona at pinks all out at martin 131 windowed the block, not a drop of oil on the track, every track should make them a requirement!!

Time and resources to clean up a mess. It's not like they all have their own Safety Safari.

I run the J&J generic fit on both my 71 Cuda (rack, struts and custom headers so easy fit)and in my 68 Cuda (SB, stock front end, Milodon pan and TTI headers).
It was tight on the A body but worked fine and passed NHRA tech for Super Street.

I agree, everyone should have one and many tracks require it at 10.00. When I was in cali my business paid anyone who won S/Pro at Sonoma $100 if they had a diaper on their car for two years. I have run one for a very long time myself and we have scattered a couple engines and not put anything on the track. But the OP asked about NHRA and SFI and that's where they stand

It is a tough deal for us street car guys that need to keep things cool...
Who has a diaper on a small block A-body with TTI headers? One of the tubes is almost in the oil pan and the centerlink almost touches the milodon pan. x2 In my case, it would be an RB E-body with TTI headers. SFI or not (The MoPig ain't never gonna see a single-digit 1/4-mile ET), where should I be looking for a diaper for this type of application? Also, how easy is it to remove one for basic service such as oil & filter change?

I see a lot of good things said about DRE - enginediapers.com. No first hand experience though.

I bought my first diaper for my Daytona back around 2006-2008. It’s still sitting unused on my shelf somewhere . It’s big, bulky, heat resistant, and free to anyone local when I find it. I will post up some pictures and like I said if someone local wants to drive here to pick it up they can have it. Sorry but I will not ship. I will try to post pictures today. This would be perfect for a tube chassis, rack n pinion big block car and was made for a Charlies or Dragster type of oil pan

Not my car, but a representative enough pic to give people an idea of how a diaper would need to fit the application...
