I think to lose the wheel hop would be to re-due your suspension and get some good motor mounts. I 'm boosting and have very little wheel hop.
Using a Torque Dampiner but I did everything at once so I wouldn't know how much the Torque Dampiner it self would help?
I have heard from a few people that have them on the car that they help. Exactly how much I don't know. I would think that they would work ( at least a little ) why else would manufatures put them on cars. ie the 5speed dodge neons 94-99.
