[QUOTE="chad linkhart, post: 1031481, member: 73264"] the stock internals can handle about 450 rwhp give or take safely you can go up to around 500 but you are pushing the limits. this kit on a otherwise stock explorer can put out 600+ with a smaller pulley. remember i am talking power to the wheels here and the 450 is safe for a 2wd less drive train loss. a 4x4 or awd i would say the safe level is around 400. you can go higher but if you do i would recommend e85 to reduce chance of detenation and realy trust your tuner. i know one of our memebers here is at 508 to the wheels awd but he is running e85.
