No track time but I do hammer it through the gears on a regular basis, that is when the coast is clear. :D The car`s running a 500 c.i. stroker with ported heads but has been detuned for the street. Now with a smaller cam and six pack induction vs. tunnel ram, it is still in the upper 500 hp range with nearly as much torque. Hooking up is a problem but this has probably helped alot to preserve the trans.. Keisler offers about 7 levels of clutch as well and I`m running the middle rated one. So far I haven`t destroyed anything, it`s fun trying though.
