s/st engine containment

astikhossw · 07-02-2013, 10:46 AM

Is the this mandantory to run in super street or optional.

A engine diaper is required for all S/ST cars. It does not have to be an SFI certified diaper but I assume one made by a recognised manufacturer. Universal fit diapers do the job and will run probably around $180. Contact Dennis from DRE and he can fix you up.

Mandatory if you run over 135 mph and well worth it. If you ever have a blow up, you will be very glad you had one.

Ok so the mandatory standard is over 135 mph.Thanks

straight from this years rule book sec 7 page 2

OIL-RETENTION DEVICE
All vehicles must utilize an NHRA-accepted lower engine oilretention
device; may use a belly pan in lieu of a device attached to
the engine. If belly pan is used, must extend from framerail to
framerail and extend forward of the harmonic balancer and
rearward to rear-engine plate and must incorporate a minimum 2-
inch-high lip on all sides. A nonflammable, oil-absorbent liner
mandatory inside of retention device. See General Regulations 1:8.

don't get confused with the gen regs. the above rule is specifically for sst. all vehicles need a diaper no matter what et's or mph they run.

Your div director or tech guys should be able to answer any questions you have.

Hope this helps

I went and checked out the websight rule book after Jim wrote his comment and did not see the 135 mph rule ,but seems like i read it somewere that it was modified a little in superstreet but maybe i am mistaken.

The diaper rule is one of those rules that doesn't necessarily overlap with the rules for a bracket race car. I can run in a bracket race at a local NHRA track with my 125-ish MPH car without a trans shield. When I attend a LODRS event running S/ST with the same car it is required to have a trans shield.

Another place where the rules will vary is with the protective clothing requirements. My car has the unaltered firewall and floor still in place and has a 8 pt. roll bar. At a bracket race I'm only required to use a single layer fire jacket, but running S/ST I have to wear both the jacket and pants.

Hope this helps clear things up for you.

I run D/G in the heritage series and an occasional S/ST race. We are required to have a diaper. flexplate shield and trans shield or blanket.

I run a dry sump motor not sure how a diaper will fit around the 6 inlet and outlet line going to the sump plus the pump fits near the sump would more than likely cost a arm and leg to fit a diaper around that stuff.

I think it is worth every penny for safety concern. Dennis at DRE is the go to guy for a perfect
fit custom diaper.
