BNB Conekillers Autocross Index System
The indexed time is a measure of how well you did relative to the other drivers. It is similar to a golfer's handicap. The indexed time will be your elapsed time multiplied by the following factors:
Tire Multiplier
Stock Tires = 0.993
Street Tires = 1.00
Sport tires = 1.013
Race Tires = 1.025
Horsepower Multiplier
125 HP or less = 0.99
126 to 175 HP = 1.00
176 to 215 HP = 1.01
216 to 250 HP = 1.02
251 to 325 HP = 1.03
Over 325 HP = 1.04
Weight Multiplier
Vehicle Weight < 1,800 lbs = 1.03
Vehicle Weight 1,801 to 2,150 lbs = 1.02
Vehicle Weight 2,151 to 2,500 lbs = 1.01
Vehicle Weight 2,501 to 3,000 = 1.00
Vehicle Weight 3,001 to 3,500 lbs = 0.99
Vehicle Weight > 3,500 lbs = 0.98
(Your Recorded time) x (Your Tire Compound) x (Your HP) x (Your Weight) = Your Indexed Time

[You must be registered and logged in to see this link.]Take a look at all the car's original stats, particularly the PI ratings. Its a pretty good mix. You want to build your car to take advantage of the multipliers as best you can, without putting it at too much of a disadvantage at the same time. Should get pretty interesting. These times are just examples so you can see how the actual "Raw" time gets affected by the indexing, your "Indexed" time is what will determine the winners for each event.
