Didn't mean to confuse ya Denny, old chassis guy stuff. After the car launches, the tires break loose... Could be many reasons for this... My first thought would be the chassis is for some reason unloading the tires,,,,,could be due to chassis flex, lack of movement on the rear at launch then when the front end settles down the tires get loose... Anyway, is this car on coilovers or leaf springs in the back????

((i did the trick were you put a plastic ty strap around the shock to see how far it travels and it didn't even move. the car doesn't go up or down on launch.)) That tells me he's not transfering enough load weight to the rear. The power over powers the load ratio.

Yup, and the usual reason for no rear end travel is the suspension is bound up someplace, or the shocks on the rear are completely wrong.... Good weight transfer that "stays" well out past the 60' timers, preferably all the way till just prior to the upshift is essential for keeping the tires planted. The science of a leaf spring sez it won't do that without housing floaters and ladder bars....a multi-leaf spring IMO only compounds the problem, hard enough to keep a mono leaf car planted, let alone the results of all those leafs in a multi leaf fighting against each other....
