During fuel check, a competitor must identify the brand of gasoline being used. The sample will be considered illegal if it does not match the baseline results (ex. color, dielectric reading +or-.2, and chemical tests) logged by SCSN Failure to pass fuel check is grounds for disallowance of the run during competition and disqualification from the event during eliminations.

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...
