ResinRick,
The short track is going to make it very hard to tell how fast a car is. I used a 16ft + stop section wooden track for several years to test/tune my cars on. There just isn't enough room for cars to "stretch" their legs. On my track a Modified car and a Pure Stock car would run very close times. I basically used it to see if the car was tracking right and as a big tuning board. Sounds like you have a good car set up. What com are you running ? Is the car a rail rider ?

com??? It is now a rail rider it was turning in to the raised wheel so I adj. and got it to turn to the down wheel lightly so I left it. the cog is alittle over 3/4". I was hopping the track was 2 short to tell and that it will tack off in the last 12 feet of track.

COM = Center of Mass or as you put it, COG.

Most rail riders steer into the rail with the front dominant wheel and keep the raised wheel off the rail.
