The NHRA site is too damn busy. What is the fire jacket rating for 9.99-11.5? Can I pass with a 3-2A/1 rating single layer, or do I need to move up to a 3-2A/5 multilayer required for 9.99 and quicker? Also what does the TPP rating stand for? One more, when do I need a harness of which probably won't work with stock '97 seats? It would be nice to make a pass without getting booted for once. Any suggestions are appreciated.

Thanks

You just need the single layer 3-2A/1 jacket for those ET's.

You need:
Single Layer (Mylar or Nomex) jacket
4 pt SFI spec 14.3 or above belts
6pt cage (main hoop, rear supports, sidebars)
driveshaft loop
(if you have relocated battery then you need cutoff switch)
SFI Crank Dampener
SFI flexplate or flywheel
SFI Bellhousing OR Transblanket

^those are the bare minimums... tracks tend to change them a little bit

TPP is Thermal Protection Performance “Fire retardant” and I have seen where some guys are getting away with passing the upper straps of their harness through there headrest.

Thanks guys. I'm hoping they don't sweat me too much on the pulley, drive shaft loop, and scatter shield. Harness cannot go thru the head rest on 97-98 year model seats, which i'm sure is a requirement. This is all for a short notice annual import race next week and not major sanctioned event so hopefully they will go easy on me.
