I disagree with this statement,especially the last sentence.It is a big deal if the diaper WON'T fit.My sbc camaro has no additional room between the stock front crossmember and my oil pan.I don't know any bracket racer,in this division, that runs 10.00 and slower that runs a diaper in a stock chassis car.

Do you have a stocker or an ET car?

If you have an ET car, why are you concerned?

If you have a stocker, why is your pan that close? Those cars have plenty of room for a diaper---unless you have moved the engine or are running an aftermarket pan.

Stock and Super Stock do not need a diapher .. we are not the problem case closed

Another issue I have not seen addressed is oil temperatures. This often does not relate to the bracket or Super Class racers as they are not "typically" running as us; the "performance based class racers".
I think you'll find a lot of the former running 50wt oils and changing the oil once or twice a season. The later will often run 10 wt oils and change it as often as every race. But maintenence, although an issue, is not the real concern I have, it's oil temperatures. Personally, per my engine builder, I don't want to see oil temps above 150 degrees based on the oil and clearances I have in the engine. He says if it hits 200 degrees, park the car until it drops. Even if it means loosing a round. Some may have a differing opinion but it's my engine and that's what I go by so I really don't care what Smokey Yunick said 30 years ago. Hardblock or similar products retain heat already.
Call it a diaper, call it a blanket, but no matter what, it's serves to retain heat in the oil pan. I see no way around this. I'd like an independent party to analyze the change in oil temp and the amount of time to cool down with a blanket as opposed to without a diaper.
And I'm with everybody else on this, I see no problem in the class. The issue in the sportsman ranks is the classes that seldom maintain their engines and continue to race when performance is suffering. A Super or Top racer that slows two tenths is more likely to adjust the throttle stop or ad more NOS than to pull the pan and inspect the engine. That always leads to trouble.
I'm sending this post to the S/SS committee

I think I'll save money and have my bogus Impact firesuit made into a diaper !!!!!!! What Next !!!!!!!! Must be certified by Pampers at a cost $100 every two years.

There are some that this would not be to hard on and others that this would just about be impossible, especialy with out a lot of cutting up of Frames, headers, and steering.
I would also like to see the data of downtime for these classes from NHRA, i know its all about TV time but is it the Stock/Superstock cars that are creating this problem? You have to realize these guys making these decisions, know nothing about a Stock/Superstock car!

First let's get over the notion NHRA is making any money on this. This rule is to prevent oil downs to speed up the races, a safety measure and
help meet the DEP standards. We have all been at races where they have
been delayed from one form of oil down or another and NHRA biggest concern is with National Events vs. the Lucas Oil or National opens for the obvious reason, TV which is great for our sport.

Second the SRAC committee has asked to see the "oil down report ". We have been told that NHRA does have one but we serious doubt it will separate engine oil downs from transmission, radiator or rear end leaks.
NHRA is going to report to the committee engine oil downs vs other track problems for Stock and Super Stock.


Woodro's post is absolutely right on. If you have a combination where its going to be virtually impossible to install a diaper or installation of a oil retention devise will create a some form of hardship ( the cost of a diaper doesn't constitute a hardship ). You need to not only
document it BUT take pictures so we can present to NHRA. Pictures are
probably the best thing you can do. Send or email this to your SRAC representative in your division.

From what we have been told NHRA wants to make a decision by Englishtown. Reason being is if we have to run an oil retention device in 2011 we have time to prepare for it. So you have until the end of May to get the letters and pictures to your reps.

In Division 1 I am going around with Bob Lang to look at various cars and to see what the real viability is for installation and servicing cars with diapers on. So if your going to be at Atco next week for the National Open and you feel there is no way to satisfy this rule without a severe hardship let me know.

When you submit your letters and photos be sure to include your name and car number. If you're not a current stock or super stock racer which means, current NHRA membership with a current license and car number don't bother submitting anything.

We are all working hard to represent you but you have to help yourself and us by submitting the letters with pictures.

Fathers car is a '72 camaro with a big block in it. Header clearance to the oil pan is very tight. DRE diaper fits great. I will admit, not many S/SS cars blow engines, but when they do it's not pretty. D2 race at Gainesville had a super stocker blow up. No diaper and hour and a half clean up. But I don't run S/SS so I don't know all of the possible combinations.
Just my 2 cents.

How much to build and install it???? I'm sure it's more than I want to spend!

Are we going to have to diaper the transmission and rear end too??? I've seen just as many broken transmissions and rear ends that have put fluid on the track as I have blown motors!!

Every car at the Division 7 ET finals in 2009 that was quicker than 10.00 and faster than 135 MPH was required to have a diaper. I would think there were a number of cars in Pro that fit that requirement and had stock front sub frames as well as a few in Super Pro.

Who will be liable for the fire that happens because the oil is trapped in the diapher and the race car burns down ?? Just curious ??? or the diapher gets hung up on the steering?? who is liable ???

Why worry about it....your dad spends his money and does all of the work on the stocker anyway....lol.
