stock t45, yeah about, 6200rpms @ 111mph


How high you willing to rev in 4th?

I would do a 4.88 and that leaves the option for a slightly taller tire if the MPH starts creeping up there. Jeff Stafford just did this and went to a 27" tire he found (its rated as a 28") Its much more consistent now too which is what he needed.

i want to rev it to about 7200,(i think im going to put some good retainers it it firts tho) and take it to a better tuner!

i was planning to go with 4:56's i thought 4:88's would be a little high but, they maybe be perfect if i rev it to 7200...

the gear ratio calculator says... 4.88', 26" tire, would be 7186rpms @ 114mph :shrug:, so i could always go to a 27, or 28in tire.
