top speed on 4.56 gears
#21
ok. here is my dyno graph. i based my gear selection on thinking that my power band would pull to about 67 to 6800 like everyone on tech preached it would lol...but, i peak at 6400 rpm. now im thinking 4.56 would put me past peak power on the nitrous. these pulls are in 3rd locked. my current converter is a 3600. based on the graph im debating on getting a 4200 converter and 4.30 gears instead of the 4.56....or just doing the 4200 converter and spraying more out of the hole. what do you guys think? i trapped 118mph on a 125 shot and plan a 250 shot to blow it up lol. that was before the added exhaust flow (the lower numbers on this graph) my math shows that with a 28" slick on a 4.30 gear would put my peak power at 126mph. hopefully another 175 shot on top can get me from 118 to 126mph.
