411 on NHRA Racing Jacket Requirement
Here's the low-down on the "racing jacket" discussion for those hitting the tracks and getting slapped with regs:
You must be an NHRA member or pay $13 for the regulations book. For some reason, my NHRA Sport Compact Racing Membership does not qualify (still waiting on a response from their helpdesk)
For reference, we are in the NHRA SPORTSMAN (Stock & Super Stock)
From the 2006 NHRA rulebook, Section 1A, (page 24)
In 2007, they added/updated the rule to read:
AND THAT is where everyone gets confused... so here is how to determine your class
STOCK:
Class 1/4m 1/8m
A/S 11.25 07.24
B/S 11.50 07.39
C/S 11.65 07.47
D/S 11.80 07.57
E/S 11.95 07.65
F/S 12.10 07.74
G/S 12.20 07.79
H/S 12.30 07.86
I/S 12.50 07.97
J/S 12.65 08.05
K/S 12.85 08.18
L/S 13.00 08.26
M/S 13.15 08.33
SUPER STOCK:
SS/J 11.10 07.16
SS/K 11.30 07.27
SS/L 11.55 07.42
SS/M 11.90 07.62
SS/N 12.25 07.82
SS/O 12.50 07.97
SS/P 12.80 08.14
SS/JA 11.30 07.27
SS/KA 11.55 07.42
SS/LA 11.75 07.53
SS/MA 12.15 07.76
SS/NA 12.45 07.94
SS/OA 12.60 08.03
SS/PA 12.95 08.22
But the class does not matter... if you have a non-oem FI/nitrous, you need to have the SFI Spec 3.2A/1 jacket.
Further confusing the situation, here are the NHRA "Sport Compact Racing Series" rules / classes:
TIME SLIP ONLY - not run at all events.
SPORT RWD - (includes AWD)
General Regulations (aka section 12) Subsection 10:10
**FYI
TIME SLIP ONLY - not run at all events, no additional requirements.
SPORT RWD - (includes AWD) - No additional special requirements*
So you can see that the Sport Compact Series is a little out of synch with the "real" NHRA, but I would guess they are paying more attention to competitions, where tracks pay attention to overall NHRA rules since sport compacts are a minority on the track and the Sport Compact Series is relatively new.
A note on helmets:
Drivers of all cars running 13.99 or quicker must use a helmet meeting Snell 95, K98, 2000, 2005 or SFI Spec 31.1, 31.2, 31.1A,31.2A, 31.1/2005, 41.1, 41.2, 41.1A, 41.2A, or 41.1/2005.
Drivers of cars running 7.49 or quicker must use a helmet meetingSnell SA95, SA2000, SA2005 or SFI 31.1, 31.2, 31.1A, 31.2A, or31.1/2005 Specs.
See Class Requirements. All helmets must have the appropriate certification sticker affixed inside the helmet.
Please make sure to keep up with SNELL / SFI expiration dates on your helmets.
What is "SFI"?
The SFI Foundation, Inc. is an independent company that writes minimum specifications for various pieces of equipment used in all types of motorsports. When a manufacturer affixes a "Meets SFI Specifications" tag to a product, the consumer, as well as the sanctioning
body, is assured that the product is made to some minimum standard. Without the
tag, it is up to the consumer and/or technical inspector to make a decision as to the level of quality in a particular product. Most SFI specifications are performance oriented, in that they define what type of testing a product must be able to withstand before failure.
How to read an SFI rating
let's take, for instance the racing jacket now required for many of us
eg. SFI Spec 3.2A/1
=========
SFI Spec = The sanctioning body
3.2A = The specification (aka "category" of product. ie: clothing, chassis, etc..)
/1 = The recertification period (1 year, 2 yrs, 5 yrs, N/A)
Minimum times for each SFI 3.2A level
SFI RATING Minimum TPP^ Value Time to 2nd Degree Burn^^
3.2A/1 6 3.0 sec
3.2A/3 14 7.0 sec
3.2A/5 19 9.5 sec
3.2A/10 38 19.0 sec
3.2A/15 60 30.0 sec
3.2A/20 80 40.0 sec
Please note that some shops/racers will just shorten SFI 3.2A/1 to SFI-1, since they know you are talking about a jacket.
^TPP = Thermal Protection Unit
^^ based on how long a driving suit will offer protection from a second degree burn in an approximation of a raging gasoline fire between 1800 and 2100 degrees F.
In a nutshell... if you have an aftermarket supercharger, turbo or nitrous and run 10.00 or slower, you need a single layer jacket.
If you run faster, you need to join the NHRA and get a rulebook cuz there's bunches of other rules you're going to need to be in compliance with.

many places will only show suits, so look for a two piece that you can order the jacket only. Prices range from $50 to $400
