pocracr Posted September 21, 2009 Share Posted September 21, 2009 Delete: The hp and torque of each dynamometer run will be averaged and then the dynamometer run with the highest average will be used in the weight to power ratio calculation: ADD: Highest HP and Torque numbers of 3 Dyno Runs will be used to calculate weight to horsepower ratio.

cosm3os Posted September 22, 2009 Share Posted September 22, 2009 Wouldn't you (or doesn't most everyone) use the highest of the three anyways to make sure you have a cushion? Link to comment Share on other sites More sharing options...
JSirota Posted September 22, 2009 Share Posted September 22, 2009 I have never understood this rule at all. Why not just declare a class? No need to declare horsepower based on anything. Should there be a compliance check, all three factors would be checked: weight, horsepower, torque. The resulting class would be calculated. If the car is in the right class, great, if the wrong one, well, big penalty! I mean, I've done way more than 3 dyno runs for my car. I can find peak HP from 159 to 191 depending on what was going on that day. Which one should I use? Does it matter, as long as the weight I race with is legal for the horsepower/torque that I race with? Link to comment Share on other sites More sharing options...
911.racer Posted October 1, 2009 Share Posted October 1, 2009 I agree with JSirota. Except for the regions that do not bring dynos to the event for fact checking. In my 944, I can change the Hp with chips and have a 15 Hp effect on the dyno run. So, I have dyno sheets showing everything from 115 Hp to 138 Hp from this year depending on the motor and chip that I had in the car (yes, I have had 3 different motors in the car) Why not just go to picking your class based on your dyno resluts and your weight without actually turning in the results.
