Scottie-GNZ Posted August 1, 2002 Share Posted August 1, 2002 Mark, I forgot the weight I used so I worked backwards and got 2790lbs w/driver. The 12.69 equates to 266.4rwhp. Not much change in the HP since the MPH was the same. More MPH is the real indicator of HP increase. The quicker ET was probably mostly from a better 60' with the DR. I would probably guess your 60' improvement was about .14. BTW, here is the formula: Sqaure the MPH then divide it by the ET, then multiply that number by the weight with driver divided by 1000, then divide that number by 9.1. Once again, that is rwhp. In your case it would be: (((105*105)/12.69)*2.79)/9.1 Quote Link to comment Share on other sites More sharing options...
