NHRA rules for 1/8th mile
The class I am running in next year only runs the 1/8th. My question is what are the rules as far as the NHRA and the 1/8th. The rulebook states everything through the 1/4.
I mean a 5 second car in the 1/8th is a 8-9 second car in the quarter are those the rules you HAVE to follow? I can get out of the throttle at the 1/8th in a 5 sec car and coast across the 1/4 in 12 seconds.
Get what I am getting at here?
Again I WILL be getting all the safety stuff to save my *** just wondering what is REQUIRED.
Thanks
MIke

Yes, if you run the 1/8 equivalent of a full 1/4 mile pass then you need the required safety that goes with it, regardless if you let off after the 1/8 5 second pass. You car has the potential of running a 9 second pass, this is for your safety, and possibly others as well.
Here is a brief list:
Here is a brief list:
- SFI Approved Balancer
- SFI Approved Flexplate/Flywheel
- SFI Approved Trans Shield
- SFI Approved Bellhousing
- SFI Approved Flexplate/Flywheel Cover
- 10-point cage (cross bar behind the dash if firewall is not unmodified OEM)
- Battery cutoff switch (even if the battery is in the OEM location)
- NHRA License
- SFI Approved (3.2A/5) Clothing
- Window Net
- 5-point harness

Thanks guys
Thanks guys
Ex. 7.52 X 1.57 = 11.81
Ex. 6.70 X 1.57 = 10.52
At Irwindale if you run a 6.399 or faster your car is considred a 9 second 1/4 mile car, and at 6.999 your car is considred a 10 second 1/4 mile car.

Quicker than 6.40 in the 1/8 will grant you the 9s in the 1/4 requirements.
George, you forgot the fun stuff.
When running 9s or quicker, you'll need an NHRA license as well. This requires:
-a physical exam (**** probe not optional)
-licensing runs (6 total if done right on each run, must have 2 current licensed drivers to witness and sign off on your form). If the car does run 9s on your 2 full passes, you must keep making runs until it does. This can be done in more than one visit, but within a limited time frame.

technically, you need to be legal for the 9s then...but 1/4 tracks rarely check your 1/8 ets. if you pull a 6.39 at an 1/8 track...they'll check for sure I bet
