Default Re: Super Stock classification

My cheat sheet.

SuperStock GT Classification Worksheet

1. SHIPPING WEIGHT

Find the shipping weight of the body you want to run in the NHRA Stock Car Classification Guide. Use the heaviest weight with the same transmission you want to run.

WEIGHT____________________________________

2. ENGINE

Find the engine you want to use in the same Guide. Find the GT Factor box at the top of the page and enter it here.

HORSEPOWER_______________________________

3. WEIGHT TO HORSEPOWER FACTOR

Divide the weight by the HP numbers you listed above. This is the Factor used to determine the GT class of your combo.

WEIGHT/HP = (_WT__________ / __HP________ = __________)

--------------------------------------------------------------------------------------
EXAMPLE 68 Mustang Coupe running a 2007 330.
(A 2008 or later 330/500 is Factory GT)

WEIGHT: 3241 (68 Coupe 428 auto)
ENGINE HP: 330/500 HP
FACTOR: 3241/500 = 6.48

NATURAL CLASS: GT/AA (Add 49 lbs to move to the top of GT/BA)
--------------------------------------------------------------------------------------

WEIGHT CHANGES

You may add or subtract up to 250 pounds to change classes in GT.
After class is determined, 170 lbs is added for “driver weight”. This is your Scale Weight. You can’t be lighter than your Scale Weight.
