Does not change the Fact that his products are the best out there and I would say that approx 80% of NHRA cars have his diapers--It is because they fit and because his service is second to None! Now..fact that I have a real race car--designed for racing and not a grocery getter turned drag car points to my many years experience working to fit things in places they won't fit like...your headers, diapers, ummm deep pans etc in said grocery getters and then coming to understand how crazy that is if all I want to do is race a fast car easy as possible--and..I can take 1/2 the HP you need to go same et --I call it a better way--not a pipe rack and ...I built 96% of it myself Geeez! Go ahead and drive yorself nuts putting a saddle on a pig or..just call Dennis and get the best product out there--oh yea--they ain't cheap.

Rocky Mountain Racway in Salt Lake City did this 7 or 8 years ago, it was a track rule. There was a ton of griping about it,they were fairly lenient with it at first, then they enforced it. I haven't raced there in 5 years since I moved east, but in all honesty it did make a difference in oildowns, and downtime at the track. I cant remember now if that rule was 11.99 or 10.99, but think it was 11.99. I bought a cheap one from Russler with the cutouts around the hole in the pan. Ive never needed mine luckily, but Ive seen them work, a big oildown that would take a long cleanup were gone. It was important there since RMR was very slow on any oildown. They didn't have the rule for street night if I remember correctly, but it was the rule and still is as far as I know.

I think it is a great rule. Most of the oil downs at the track these days stems from relatively stock engines with 200+ shots of NOS to get them to run 11.99 or quicker E.T's. those engines are usually not made with good, solid, dependable premium parts because their owners are ignorantly cheap, which they in turn blow up spewing oil all over the track and under the cars tires! The time waiting for clean up will be reduced dramatically as well as having a more consistent racing surface along with more time actually racing not waiting for track clean up. The people who complain about a SAFETY rule which will benefit EVERYONE now and long term, should think about the positive aspects of the rule not the $150-$250 which could very well save THEIR LIFE! If that amount of money is deemed too much for what it can and would potentially save, you should seriously re-think your priorities and the value you put on YOUR LIFE!

No biggie yours will take 10 seconds to install lmao

BINGO. This rule with pay big dividends with less clean-up times, safety, and track costs. Nothing worse than spending an hour in the staging lanes on a 90 degree day on something that could have been prevented.

You guys are missing the point. There is no doubt that it will save down time and of course the safety issues. The point is: Is it needed for a street cars, that go to the track periodically? I see a need for it on "ALL OUT" race cars based on performance levels. I see absolutely NO need for street cars running test and tune or an occasional class race slower than 9.99 seconds. To me, this is over kill.

Have you ever gone to one of PRP's street car only races. I have and there are lots of oil downs during these events too.

Agree with you completely. I have lost an engine at speed. Put a 6" hole in the block and not even a wobble out of the car. The accidents I have seen that were bad were usually traction related or involved a broken suspension or drive train part. Not a blown engine. Your experience may be different than mine and that is fine. Point is there are risks when you race and I see little to no benefit from this rule at the speeds 42 is wanting to enforce. IHRA must agree because their requirements are much different.
Also on my car there is no way one will fit between my headers, oil pan an k-frame or pan and center link.
I didn't build this car to be a dedicated drag car. Its street strip. It will run high 10's to low 11's. Just over kill like replacing belts & window nets every 2 yrs and a money maker for the sponsors.

Bingo!

Well I might be alone but I put one on mine volunteerily. I only go through @ 133 to 135 but I feel better that I might contain the oil in the event it lets go.next project is a belly pan for the trans. BTW I had one made by JJ performance and fit well but tight on the steering link,I glued a thin piece of neoprem to the diaper and no rubbing issues.

My Polara runs 9.90s so even though I am too lazy to get a license, it has a diaper. The challenger runs 11.50s and I would run one if I wasn't worried about oil temp on the street. Don't know if that would be an issue or not.

Rather than requiring it on 10.00-11.99 cars, why not give racers incentives to run one? Whether it's an extra run on a t&t day, or even money incentives. I was told that a racer at a track here in MD paid the next entry fee for a racer who wasn't required to have a diaper but had one anyway and ended up grenading a motor. Costs the track more than that to clean it up, so it seems like a good idea.

One of the most horrific wreaks I have personally seen was a low 12 second S-10 that blew mid track and knocked out the right slick. By the time it was over the truck was on the guard rail with the cab, pivoting at the front bumper, upside down in front of the chassis, driver hanging upside down as well. Engine containment might have prevented this.

One car, blowing an engine with a containment device, might be the difference between finishing a race and not. And when you drive 600 miles to get there.....

Most oil downs I have seen are those 10K rpm imports ,, yes they fly ,but they grenade regularly...JMO

I can see benefits but it is going to kill the entry level participation. .. If I don't sell my Wagon it will be restricted to 12.0 and slower brackets... this is just overkill... so they are going to make the new muscle cars capable of running 11.99 and quicker get a diaper. .. people are not going to go to that effort on a new car.. just to go have fun at the track every once in a while. And there will be a bunch of 60's era hot rod owners who will pass on all that just to make a trip down the 1/4 mile... bad decision for a sport that is struggling to bring in new participants.

I can't say I haven't seen slower cars hurt engines and cause oil downs, but most of the problems I remember seeing at those speeds have been trans blowups, not engine damage. You can add my vote to Overkill! opinion.

If my local tracks do start requiring this for 11.99 and quicker cars, how difficult is it to install one on a B-body street car with tight fitting (tti) headers, a full exhaust, but no power steering? I use a Street Hemi pan, so would I need a custom made diaper to fit the pan? It already looks kind of cramped under there to me.

John treed me on this, with his separate thread...

IMPORTANT ANNOUNCEMENT UPDATE

by admin · July 6, 2015


A wise man once told me to be successful you have to be flexible, so we have been listening and discussing it at length both in house and with other operators about the ET Break for Mandatory Engine Diapers/Containment Systems. There are so many pros and cons about diapers and the use of them that a firm number for the ET Break could not be established so we are changing ours to fall in line with the other tracks and sanctioning bodies.

ALL CARS IN ALL CLASSES THAT RUN FASTER THAN 9.99 IN THE 1/4 AND 6.40 IN THE 1/8TH MUST HAVE AN ENGINE DIAPER OR CATCH PAN AS PER IHRA RULES.

We wanted to act quickly on this so those that don’t have them can get them if needed and to tell those that were going to get them not to unless they want them.

Finally, Chuck, the voice of reason. Although not a proponent of diapers, I would think that 9.99 might be a more reasonable number.

I have been watching this thread....Ronnie & I host a monthly Nostalgia deal at PRP, and it's been fairly successful in getting some of the old race cars out of the garage, at least once a month. Most are not hard core racers, but old racers with old Maxies, 409s, etc.

I know that telling these guys they'd have to put a diaper on their 11.30 Maxie vintage race car would cause them to just roll right back into the garage and slam the door, again. In my case, with a Hemi B body, I'd probably finally just park it and head to nostalgia shows because, to be frank, for me it just would not be worth the hassle and nightmare of putting one on. Some of us have been doing this for 30, 40+ years without one, and would not do it because some 19 year old kid with a turbocharged 6 cylinder that revs to the moon comes apart when he pushes the nitrous button. I've made literally thousands of passes since 1969, and really could walk away from active racing tomorrow. When one reaches a certain age bulls##t comes a bit less tolerant.

Personally, I think this smacks of the two year belt rule, and others that seem to be designed to help contingency sponsors. All of a sudden we will find "ABC Company" has the "approved" diaper, and BTW just happens to post contingency money.

You guys are using your head, Chuck. BTW.....in a shameless plug, the next Bud's Auto Sales Nostalgia Combo Eliminator is scheduled for Friday, June 17. You can check the site, or check the facebook page.

I checked on the web and the Salt Lake rule I mentioned above was 11.50, that is their cutoff for diapers

Wow. Glen, a good, hot street car can run that....interesting to know how that is being received.

Myself on my stret/strip car I really dont care to have one. But honestly I dont know how much it will effect or how much hassle it will be on my street car. I really love to go to the track and race in the Nostalgic Superstock races when I can which is not as often as I would like to. But I drive it on the street all the time as it is a street car first and most and I drive it to the track many times. I guess I kinda feel like "Steve 1118" as myself I have raced off and on since my first trip down the track in 1975 and have never blown and eng and I bracket raced a 340 four speed car for 5 years. I hope I dont have to buy one and put it on as my funds are tight right now and my car is not a race car as its a 99% street car. But if they make me then I guess I would as I just love that blast down the track whenever I can. Ron
