I was just looking at our lovely online NHRA rule book and from the way I am reading things a diaper is not required until you get into advance ET running 7.49 or faster am I reading this correct? Under super pro running 7.50 or slower it states a diaper is permitted but doesn't say required. 70 duster full chassis super pro 416 CNC Indybrock heads 727 w/brake best so far 1.212 60 6.219 in 1/8 at 110.88 9.768 at 137.81 1/4

I know after the hemi had the rods try and get out the side of the block and 155 and there was not a drop of oil on the track I wont be without one again.

The NSS organization i run with had an incedent a couple weeks ago that could have been avoided had the car that lost the motor had a diaper (or if the track was cleaned.....) Luckily no one was hurt and the damage was minimal.

I get the safety argument about having 1 but I am just looking at letter of the way it is written and if I am required to run 1 or not from the way I see it it's not required with me running a bracket super pro car running slower than 7.50. 70 duster full chassis super pro 416 CNC Indybrock heads 727 w/brake best so far 1.212 60 6.219 in 1/8 at 110.88 9.768 at 137.81 1/4

The belly pan 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. [ home of the Sox and Martin Hemi Duster

UNLESS you run Comp, Super Gas or Super Comp, they need one regardless of ET. "I am not ashamed to confess I am ignorant of what I do not know." "It's never wrong to do the right thing"

A diaper wont work on mine but I'm in the middle of a belly pan project which looks like may work well. I'll post some pics when its installed. This to me is the best approach. You get the benefits of oil control, and improved aerodynamics through better airflow under the car. Might as well extend it forward a bit and add a front air dam under the valance? Kinda follows the philosophy, nothing rides for free! 8..603 156 mph best, 2905 lbs 549, indy 572-13, alky

As for the recert only Top Sportsman, Top Dragster and faster require SFI certed diapers. You will be fine with just a sportsman diaper.
