Lou,
I called the div 2 office. They gave me a # in California. I talked to a lady there that said.
Yess on the shield
No on the net and cut off.

One more question When is a diaper required?
Thanks

Re: sst tech questions car under 135mph
 

Diaper same deal, break point is 135...under and you're good 'by the rulebook'; speaking of, with a number you can go onto NHRA.com and create a password and then be able to have a PDF or E-Book of the Rulebook. My 2C is put a diaper on if at all practical even if not required.

Just because you're not required to have a cage with a stock firewall doesn't mean any official might interpret a window net requirement a bit different than what the lady in CA indicated...I'd put in a window net and save some future hassles.

I don't have diaper,flywheel shield,or fuel cutoff. I have everything else. will order shield tommorrow. Diaper will have to wait until this winter.
I do have a full cage and window net.

Check out all the SST cars running under 135, many do not have diapers...for the time being 135 is the break point for license, chassis cert, diapers, gloves, etc etc....135 is where you have to have a legal SG car (plus the weight of course) to run SST.

Got shield today
Does fuel pump cutoff have to be at Back near cell or inside the car?
Sorry to sound stupid but I don't have a rulebook and can't download until I get a membership #

NHRA general regulations state "nom OEM mechanical pump must have a quick action fuel shutoff valve within easy reach of driver and located in the main fuel line between the fuel tank and carbuerator and/or injectors."

If you have a fuel cell, make sure it has a ground strap.

Gary,
Thanks for the info. That is what I thought.
I,m officially a card carrying member of the NHRA again. I've already figured out not to call Cali for anything. LOL

Re: sst tech questions car under 135mph
 

i was refering to the 3 original questions
flywheel shield/yes
window net if you have cage/yes
fuel shutoff with belt drive pump/yes

Re: sst tech questions car under 135mph
 

I think I disagree on 2 of 3:

Flywheel shield is required at 9.99, not 10.99. Trans shield/blanket is required at 10.99 and for S/ST. So a flywheel shield is only required if you go 135.

Only if the car is "required by the rules" to have a cage is a window net required. If it goes under 135 and has a stock firewall and floor pan, you can have a cage without a net. If not, then yes a cage (and therefore net) is required at 10.99 and for S/ST.

It's a good idea to have the more equipment, the better. And on your first trip thru NHRA tech, no guarantee you won't get an inspector who doesn't know the nuances and says "I am the rulebook!" and gives you trouble. You don't want to have that argument, even if you win on Monday, you lose on that weekend.
