hardly any warm up time needed,i think with my 735 hp it tells the story,launching from dead stop no problem, remember i also have 850 rwtq,call luke at tirerack, he will set you up. even if you break halh shafts its only about 1700 bucks, you still havent told me what year car you have, the newer vipers have better halfshafts. lots of luck,ps i not crazy about racelogic holding back on acceleration with stock tires, may be ok for racecourse,but im a drag racer.
