I'm not drag racing as this has been going since the car really got the motor broke in three years ago. With my wife driving the car full time again it finally just broke 10k. She hardly drives over 4500 rpm's. Some of the things that I read was that the trans can't handle high horse power. On low boost I should be putting about 450 on high somewhere around 650. This could be why I have a problem I'm just not sure. With symptoms that it has and my experience I have been going at this as a clutch issue. Maybe you got lucky.
