Was finally able to get the sled out.
Saturday at Mid Michigan Motorplex
Michigan Snowmobile Asphalt Drag Racing Association
Thunder Products Clutching Bracket Series Sponsor

Race # 3 1/8 mile racing
Everything went pretty well.
First pass was 6.44 @ 103.71 mph. Right off the trailer, first pass since setup in the shop. Rpm’s were 200 low but AFR was a little lean but ok to race. With only being able to run 2 passes before racing I decided not to make any changes and run it.
Second pass was 6.49 @ 103mph. Close enough to race.
Round 1. Dial 6.44. Ran 6.50 @ 103 mph. Won reaction time .050
Round 2. Dial 6.44. Ran 6.49 @ 103 mph. Won reaction time .070
Round 3. Dial 6.46. Ran 6.49 @ 103 mph. Loss reaction time .135. Loss due to poor light by me. Lost race by .020.

Overall I had a great day. New sled just setup running constantly is a great thing. With adjustments I see 6.20’s next time out, with a goal to get below 6.10 by our last race.

We had 56 entries in this bracket group for this race. We also average over 50 sled per event.

By the way this sled ran the fastest times of all stock motor 800 and 850 sleds racing this series on its first time out. Without any testing or dyno time.

I would like to thank everyone that helped out with this sled.

Basically it's in the setup. Our clutching coupled with suspension setup so that you do not spin. How the sled sits and reacts after the hit is key. no/very little ski lift so that you get good weight transfer and move forward not up with front of sled.
