Engine diapers on S/SS?

[rboyle]

We had a D1 race where 3 Stockers oiled the track during the first Qualifying shot. I myself have oiled it twice. First when I bought the car I was the first car down the track at No Problem and spit a rod out at bat mid track broke the trans driveshaft and pinion yoke too. Shut the track down for almost 2 hours. So yes it does happen.

After looking at the B-E body engine, steering, and headers on my stocker, it would be a lot of work and expense. The drag link runs real close to the sump and the bottom of pan, this could be a potential crash if the Kevlar blanket jams the steering. A motor plate would not help the steering situation. A tray might work until a big wheel stand. When that happens on my car it bends the oil pan against the pickup, and bends the transmission pan. The oil pan I have to fix before I make the next run. If new ss headers are needed to complete the ORD I will be done.
All of a sudden cutting bait doesn't look so bad.

I must have done something wrong on my '64 Dodge when I put the engine diaper on it. I have the factory K-frame, steering, and torsion bars. Using 1 3/4" Hooker S/C headers (one tube through fenderwell). I fit a universal Jeg's diaper on the car without issue, though I did have to get creative with some of the mounting points for the support straps to hold it up.

I wasn't real fond of putting it on, but when the rules require it (I ran the car in S/ST a few times...ex-SS car), you find a way to make it work if you want to race.

While the Jeg's diaper doesn't provide the best fit, I can only imagine how much better the job would have been had I used something that was designed for the car.

Don't have a dog in this hunt, but never stopped me before.

Steve, I don't have a rule book, but are you saying that S/ST, the entry level class, where the index is only 10.90, requires a diaper?

Mark, yes an oil retention device is required in Super Street. Believe it would already be in place but the last time they floated it the heard how much of an impact it would be. Strangely enough bracket cars don’t require, likely because they don’t put the Fuel Circus at risk of losing any track time. I’ve already submitted my impact statement to the SRAC. Have a Stefs pan with hole for the drag link to travel through, custom made headers by REF that come very close to pan in several places. Even if one could be custom made it would come very close to the belt drive. As stated earlier if they hand down the rule as mandatory then current car will no longer run in Super Stock

Correct...that and the flywheel shield were the only two things I had to add to the car for S/ST. I know a lot of tracks were requiring a diaper on Sub-10 second cars as well for their weekly bracket programs. I don't know if I needed the flywheel shield though as the car runs less than 135 mph?

I don't think the diaper should be mandatory...but it's definitely cheap insurance.

For what it's worth...The rulebook does state that a minimal number of slots or holes to "clear frame, steering, or lines" is permitted.

Well guys, There's a way to address the S/ST issue.
No electronic throttle stops , and a 125 max speed (breakout).
In other words, bring it back to entry level.
But why in the hell would they?
Look what they've allowed to happen to Stock.

Why would you think S/ST is supposed to be entry level?

I only go 12x MPH on 9" radial tires, but I like the diversity of the class just the way it is.

I don't care if Stock and SS are allowed to run without a diaper, but the drag link through the oil pan and close-fitting headers are not issues that would prevent one from being used. As I mentioned in my first post, my diaper has holes for the stock motor mounts and has Kevlar side panels where the headers touch.

Larry I love your pink car. And I'm jealous of all the races you get to go to. But if you were to cut bait could Patsy still go and report. Class racing would not be the same without her. Barry

Excessive RPM's will do it every time. Now you have solid lifters to go along with the killer valve springs and excessive duration cams and roller rockers, etc. ! What else would you expect unless you spend several thousand more dollars to build modified and S/S wanna be engines. You get what you wanted !
