Thread: NHRA rules

Tweet

Hey gang. I'm getting ready to order some roll bar tubing for the 'maro...anybody have a new rule book handy to see what the spec for moly tubing 8 point roll bar for a 10.90 car is? Think it used to be 1 1/2" X .083 wall......???????

Thanks

Found the spec on a google search that sez 1 5/8 x .083, but I thought that had changed for moly??????

1 5/8 083 for moly

1 3/4 134 dom

some rules have changed

most differences are probably in the braces

Ok, thanks Jerry. Have to go find me some updated specs I guess. 1 5/8 .083 it is.

Heres YOUR AVATAR.....if you still want it....

Let's kiss and make up......well.......maybe shake hands and make up. Sorry for showing my a** in public. My apologies to you and all. I've resumed taking my meds and all is well. Sometimes my compass doesn't point to North.

It's great to see you making your presence known again, Richard!

The absence of your many expert contributions has definitely been felt.

I, for one, am looking forward to "business as usual" ........ just like it used to be.

To quote (more or less) that old motel commercial, "we've kept the light on for you".

Thanks Jim, I appreciate it very much.

Top Fuel-Goggles now prohibited. Must wear full face helmet with shield. SFI 31.2A, Snell SA2000 or SA2005. Must use skirted helmet with built-in SFI 3.3 sock or separate SFI 3.3 head sock if helmet is not skirted. Neck collar not required with skirted helmet or separate head sock. (Secondary function of neck collar was to prevent fire from going past the neck and up into the helmet. That function is provided by the head sock now. Driver can elect to use a neck collar with the sock/skirt if he/she desires) Must use SFI 38.1 HANS device.

The majority of the rules are there for a reason, unfortunately many times the reason was injury or death. If NHRA wants 1 5/8" .083 wall tubing, sounds good to me..... I've lost way too many friends to freak racing incidents over the years to question their logic, or yearn for the "good old days" when safety was for sissies.....
