It would be a pain to install a diaper on my Dart. Small block, Hedman headers and a Milodon oil pan I had to section to clear two tubes on the passengers side.

Get ready for the smell of burn/melting nylon!

I agree 100% on overkill...He11 11.99 cars aren't even required to have a roll bar. The best way to find out what's going to be MANDATORY is to see who NHRA's next sponsor is...Now what did I do with them Collector Tethers...LOL Its all about the Benjamin's

I agree. I also know I won't run one. I don't see very many high 11 second street cars scattering engine parts at the track. Mostly the full out race cars. Rules like this are going to kill participation by the average street car racer. Low turn out will lead to higher entry fees to make up for the lower $ intake..
Dragway 42 is an NHRA track? Pittsburgh is an IHRA track..I wonder if Pittsburgh will invoke the same regulations as 42?
Just my 2 cents and thoughts... I'm done venting.

42 is a ihra track that is all new and rebuilt

Everyone I know that runs one the engine temp(and trans)
has gone up... on a street car this MIGHT have its problems..
I'm not for it on a street car... to be more realistic I would
have said 9.99 or quicker... before it was for NHRA races ONLY

I'll put a diaper on my stock a12 road runner..(SURE).. There nuts!!

11.99 is not that fast today.. I guess new cars will have to come with
them installed from the factory..

At least line it up with the bar rule and make it 11.50 !

Yeah, what about box stock Hellcats, Vettes and Mustangs that are deep into the 11's and 10's already?

Perfect way to discourage ANY from wanting to go to a track.
I wish I could curse and tell you what Big A......s run the association.

Been looking forward to 42 opening again. But with this requirement I'll spend my money and time elsewhere. Counting 42 there are 7 tracks w/in 2 hrs of me so I can go elsewhere.
Plain stupid to require this at the listed times and speeds. I can see this being a requirement at the level where the racers chassis needs certified or as noted in the IHRS rule book for 2015 but not at slower limits. This appears to be a track rule.
All this will do is send people to the non sanctioned tracks or other IHRA tracks that are going to enforce the rules as written not make up their own that are more restrictive.

Diapers are great. But to require one at an et slower than a stock Hellcat is stupid.

The streets will be on fire. I guess the street outlaws have been ahead of the pack.

Any engine can blow at any time, wether it' runs 3 sec or 15. Why not make it mandatory for everything.

this is for CLASS RACING. NOT for test and tune cars.

So unless your racing in a class, this rule doesn't apply.

The dragway 42 rules says any CLASS - last I looked trophy class was still a class. So is Street, Pro, Super Pro, etc. same as Stock, Super Stock, etc. I'd venture to guess it's the ET and not the name of the class that will be the deciding factor. While I realize you probably don't run at dragway 42, as was mentioned, the knee jerk idiots at NHRA, especially if they smell a quick buck to be made, will slap a ridiculous rule on something faster than you can spit.

In the spirit of where this topic is going, here is my proposal...

Engine Containment Diaper only required on:
1) Chassis cars including dragsters
2) Professional Class cars (TF, Pro Stock etc.)
3) 8.50 and quicker 1/4 mile, associated 1/8 mile
4) All throttle stop classes (since they can run faster than the index)
5) Any car with a non-factory power adder (Nitrous, blower, turbo)

Specify cars with factory front frame rails do NOT have to have a diaper unless one of the above apply.

Someone is going to have to explain to the new management of this drag strip that this new rule will cost them money, in car turnout. It's hard enough for drag racing venues to stay afloat without shooting themselves in the foot like this.

Test and tune is not a class.
So if you just take your car to the track and want to make some runs, this doesn't apply.

I guess I will have to go to fenderwell headers when Royal Purple Raceway mandates the diaper rules, I don't think my TTI headers will allow for a diaper with an RB in a Demon. Mo money, Mo money!!!
