Since I made the post this morning, I have recieved PM's from several people that have had the same issue with their SP motors on the track (under load).
The lesson I did learn is: There is a reason why the used Tekin motorset snatched up in minutes on the classifieds board and the SP stuff sits on the board for days.
Your posts are a little suspect. First why in world are having to pin a boosted 13.5 in a truck. Are you really having to try and raise the nose that much. If so check that truck setup it sucks. Second. I seriously doubt your receiving a bunch of pm's about exploded rotors. Where are all the other posts on this thread talking about it? It seems to me you just a tekin guy by what your posting. Post a picture of that rotor please.
