It is a tough deal for us street car guys that need to keep things cool. If I have to I will put one on but I will complain the whole way lol. I totally get and support the purpose it will just be a PITA on my car.
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.
We can probably thank the LS crowd going 8s on salvage motors for this stuff lol.

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'd agree with the rule. Yes diapers can be a PIA, but are worth the hassle. I lost my engine going thru the traps in a 11.20 car a few years back and fortunately I only had about a quarter size hole in the bottom of the pan, but crack both sides of the bottom of the block. It sure wasn't the most fun I've had in a car and sure changed how I approach things moving forward.

It's always fun being strapped in, and the guy in front of you oils the track down. Usually at best it's a hour clean up. There are only so many racing hours in a weekend. Don't be the guy that wrecks it for everyone else.
Don't get me wrong, stuff happens, but with what we know today, and the price of a engine diaper, there is no reason to not run one.

All 3 of the .90 classes are required to have an accepted device. Bracket specifications say they are "permitted". No mention of it in S/SS. At this point, I believe it's mostly up to the track. Our local track rules state anything quicker than 10.0 need a oil retention device.
If the results don't match the theory, change the theory.

I think this is one of the few recent NHRA rules that is a really good idea.

I wish I had my engine out so I could post some pictures of mine. It cost 200.00 some dollars and can lay right on the headers. It measures about 1/4 inch thick. Inwill be picking up another one for my big block soon from our track manager as he sells them for cost.

Pittsburghracer...... do you know what brand yours is? I’ll find out. Pretty sure it’s made in Ohio. May be j&j but let me check. I know it’s universal and comes in two sizes.

Here is my "street" car at 108mph, loosing a rod out EACH side of the block...Pretty sure had I not had one on, the car would be toast...Not a drop of oil on the track, 10 quarts of oil....I use a DRE system on both of my cars with Big tube headers....
