Thought I would build a new challenger for the 2.5 inline class.

Put together a BSRT chassis for the Super tire truck. After some tuning it was giving the Inline class winner

some close races. They ran side by side for 2 runs with close results splitting wins.

2.5 match race]

2.5 match race 2

The truck has the better 60' but the 55 has a little more power catching up on the big end. 2 super close races.

I always find that kind of stuff interesting. If you watch the actual race it looks just like the times show. The truck takes the early lead and the 55
starts to close the gap at the stripe. Cars are identically prepared except for the rear tires. Both use silifoams, nothing else will stay on the rims, but the truck has the taller tire. It would seem that the truck should have the higher trap speed but it is not the case. Don't know why, logic does not always apply when racing.
