any concencus on what is the optimum rpm for launching a stock auto? this is assuming a launch from a brake stand or break torque i think some of you call it. i have tried up to 1800 which was ideal for my old 5.0 and she (my 03gt) lopes casually off the line. i am thinking that since this 4.6 likes the higher rpms that i may not even be making power yet at 1800. how high can i go and not break the tranny? i have it in my head to try a launch at 4000 but havent done it yet because auto trannys aint cheap and i do NOT want to break this one.
