i was trying to figure out how you determine when shifting to the next gear how much the rpms will drop in between shifts. im trying to pick the best tranny for my application so the revs dont drop to much, but at the same time not for the gears to be short.

gt4294
full boost @7000rpm
redline 9500rpm
25.1''tire

current tranny is a ls and it falls out of full boost on the 3-4shift pretty bad.

yea i was looking at that and plugging in a few different trannies, but how do i figure out how far the rpm's drop between shifts with each of the trannies?

 

GSR is he the the best tranny i would think so im having the same problem i was running out of gear before the qauter mile i had a b16 trans i recently switched the ring gearto a 4.266 final ls and kept all the b16 gear im revvin to 10,000 24x5 i recently put up 146 mile an hour i almost sure gsr is the way to go bro thats where im heading

 

The rpm drops are shown in the calculator as "Shift Points".

If you want to know the rpm at different speeds, move your mouse over the graph.

 

yea i was thinking about getting itr 3rd and 4th gears and keeping the ls final drive. I just dont want my revs in between gears dropping below 7000rpm.

 

where does your rpms drop between shifts?

 

i would tell u cant look down goin to fast lol i get full boost around 7400 i slightly fall out on the 2 -3 shift only made 1 full pass since i changed it trans set up
