It is another expense no one was planning on that's for sure.
The pro classes were the first to get hit with this a couple of years ago.They have pretty deep pockets but I'm sure they have asked NHRA "How come we're the only ones getting / required to do this?" .
Now it's just filtering down to the other classes.
Don't think it will stop @ 9.99 either.
Rules have always stated you are not supposed to leak on to/ leave any fluids on the track.This is an extension of that rule.
Just like a catch can this will probably,eventually, become mandatory equipment for all levels of competition regardless if ET. class .
ANY cars running power adders like; blowers ,turbo,nitrous,nitro methane ,should be given special attention anyway no matter what et the car is running.
I can agree that the slower classes of racers , by virtue of their sheer numbers alone,are going to be the source of the majority of oil downs.
A properly built and tuned overhead cam engine can safely spin way past traditional V8 redlines.
I've seen just as many 10.0 and slower oil downs caused by "over tuned " domestic cars that could not even safely sustain 6000 rpms that probably shoud have had a 5000 rpm limiter chip in them.
Hopefully slower cars may not have to run the same cost / spec. device.
Just like the way the rules are structured for roll cages,belts, on board fire suppression , chassis certs. , 'chutes , competition licences ,etc. etc... .
If there is a broader market for the engine diapers the prices will drop.
They could be made inexpensively in China .
A lot of guys will go spare no expense on horsepower .When you start talking about safety equipment and certifying that it works they start bitching.
The engine diapers could also help from going out of control via running over all of your own oil should a catastrophic engine failure happen.
Just think of it as more safety equipment.
