the only thing i tried was on the ice at a radar run. used 150 #6 sheet metal screws per rear tire. I got 65.7 mph wound out in fith long before end of track. Run was 1000'. thought with more traction i could get 70+. 2003 box stock raptor.

 

I had 1.8 60 ft. and 9.006 at like 69 mph. stock sprockets and tranny screwed up that race, was only second. I was way topped out at the 1/8.
