It seems that there is a lot of friction in my track and drive system. 
I have replace the wheels and bearings. 
The friction eases when I loosen the track, but I get a ratcheting problem if I loosen it from the present tension. 
I get a ratcheting problem only when I am doing rainbows at full throttle. 
The track makes a noise when I come back down on the road hard with the throttle on hard. 
The lugs on the track and the drivers are not broken and I would like them to stay that way. 
What do I check next?

Sounds to me like you need a dual drive setup, internal&external, involute&clog setup
or (whatever they are called ?)

Are you talking about anti-ratchet drivers like the bottom of the following link?
http://www.hartmaninc.com/tracks.html.
I look at the tracks on that page and wonder how to fit one in the 86 vmax tunnel.

Joe,   Link does not work ?   Anti ratchet sounds right but I'm not sure.   There are drive clogs(?) that use the internal lugs and the track windows like older sleds.
