For a 3-speed Automatic Transmission (This Deduct does apply towards a Pro Trans, A-1, Scott
McClay or similar light-weight
Torque-Flight,
TH200, TH350, etc...) Figuring
out your Weight:
This might seem to be complicated, but it really makes for very competitive
racing!!! First of all, you need to know how many cubic inches your engine is and a calculator to
make it easier... For example you have a 550ci Big Block(3200lbs) with
Sheet Metal Intake(+10%), Dry Sump(+10%) and a Power-Glide
Transmission(-15%) Total up your weights adds and subtract your weight
deducts....You would take your Cubic Inch multiply by the amount Adds or
Deducts and come up with your PSCA Race Weight......Example for above...
Add 10% + 10% - 15% which equals a total of 5%.. Take that 5%x 550 which equals
27.5lbs, add that to your 3200 Base Weight (27.5 + 3200 ='s 3,227.5lbs) Your
SCSN RACE WEIGHT WILL BE 3,228....We will round up all figures to the nearest
pound.. If anyone has any trouble figuring out your weight for
your combo, you can contact Mel at 661-609-9486 and I will assist you...
