Will timing advance effect engine temp.

i agree with the above, nothing like the load of a holeshot, increasing load on the engine after each gear change, etc. I think the drum on the dyno is about 2200lbs if i remember right. On a full size 'built-in' one atleast.

Dyno may get you 'max hp', however it wont tune your combo for a 1/4 mile pull.
