Diapers are great, IF they fit and you have room. The OP has already stated that his headers basically hit the block. You might get a diaper between that, but eventually it IS going to burn it up. Also, unless the whole thing is a ballistic blanket, it's not likely to contain a violent let go anyway. If your headers hit now, a ballistic sure isn't gonna fit.

I never said a pan would be easy, but it CAN be done. The bottom of the pan can be right against the oil pan, so will be no lower, other than the thickness of pan and a piece of pig mat. Plus they are easy to remove. Ours comes off with 6 dzus fasteners

Never used them but have heard a lot of good things about Russler. I guess I might as well add that to my list of things to buy, too. I wonder how many other local tracks are going to institute this. Rockingham, Jefferson Pageland, Moorseville, ZMax?

If you go with a home built pan, be sure and figure out a way to make it easy to inspect for oil or water in the pan, and do it often! I built one that was very close to the frame, couldn't check it easily, and had a serious incident as a result. A fast repair in the pits, put the whole deal back together, got back in line to make a run, and five feet off the line the car went hard left to the wall, so close I swear I could see the grain in the concrete wall. There was a slow water leak, and it splashed out of the pan on launch. Yes, I did have hasmat in there.

So when does IHRA or NHRA actually require a diaper?

Does this mean a Hellcat Charger/ Challenger with Drag Radials will have to have a diaper too?

Yes they would encourage it.

How do the belly pans work? Is there a certain height that the sides of the pan has to be? Is it supposed to be a full surround? I'm asking because my new frame might lend itself to a removable pan. Might be easier than a diaper.

DRE is what I have. Fits good.

About how much does a custom DRE diaper cost?

All I can add to this is if you have ever broke a motor(windows on both sides)without a diaper, you will never run again with out one...Watched my Dad crash his Mercedes after spending 6 years building it due to a rod failure that oiled both slicks and made for a bad day...It is worth its weight in gold to save yourself a lot of headache. Pans are nice but do not contain all the oil in an engine failure as well as a diaper.

NHRA requires a diaper in Supergas and Supercomp

actually those who mentioned the new Challenger that would be easy. They already have a plastic belly pan that mounts under the engine. Make the same deal out of metal and layer it with Pig blanket and you're good to go.

One thing about the blanket it's much easier to cover the lower part of the block with the deep skirted big block than it is a small block. Wish mine came up a bit higher, but that would be tough.

So a diaper isn't required for 9.99 or faster? Just certain classes?
That's all I could find when I looked through the rulebook, just wanted to be sure I didn't miss anything.

.99 and quicker and you must have a diaper to race on their track.

You are correct HOWEVER there are many tracks that have already placed the rule into effect. 9.99 and quicker and you MUST have a diaper to race on their track.

Right...which is exactly what I'm dealing w/ here. Only my track is saying for 10.99 and quicker you need either a diaper or belly pan, which I think is ridiculous. A 10 sec car shouldn't be required to have one IMO.

I'm not exactly a fan either(I have to have one this year also) but last year at one of our races at ST Louis a 11:00flat index pontiac blew the motor in 3rd gear, he had a diaper and the clean up took 10-15mins and it was mostly water, later in the pits after it sat an hour or so the oil started dripping out of the diaper. so they do have their place.

A motor coming apart in a race car is not really relevant to ET anyway. I see more thrown together, slower junkers scatter motors than nicer faster cars anyway. It's mostly about cleanup. Many local tracks are far from having National Event track prep equipment, much less the manpower. I have seen a major oildown cancel a night of racing more than once

I had a freeze out plug come out on me a few years back,A diaper is a PITA when the center link goes through the pan.
Spoke to the chassis shop today,been on the waiting list all winter for some other upgrades,a belly pan will run me $800 to $1000,,,,,,,,it's only money...............

DVD,what do you have to do to change the oil?????

I bought one of his and cheaply made. Material is nothing more than a light canvas. The wrap straps are made of thin nylon and catches are plastic. Those two items are identical in very way to he belly bag joggers wear.
