I got a chance to run my sled on the track dyno. The stock clutching wasnt real bad, its much better than what a stock Mach Z came from the factory but still not to its potential. Stock with D&D Y pipe and bullseyes 82hp at the track and my kit put 89hp to the track with a ton more bottom end and mid range. This was with a 15" track and 170 studs, sled now has 30 miles on it with dyno time. These numbers will be very close to a properly set up Mach Z so it should bring the two closer together. I also found that the sled will gain more power by adding fuel in the mid range. These numbers do not reflect that but I did back that up on 2 pulls. These are also with a heat soaked engine as I did not have a cool down cart hooked up to keep it at near perfect condidtions so this would resemble trail power! These dyno sheets will be posted on our web site soon........
