I found this website withv teh quy posting this speed per each gear calculator. http://www.forums.maxima.org/p...70049
i adopted it to a m2b4 transmission with one of my sets of tires. my question is, what is the 168 that he's using in his calculator. i copied and pated my excel cells into here so you can't see all the calculation, but does it look right? I've heard people saying they've been up to 140+ in their 4g's so this make sme really skeptical unless they got on 20" rims

and on teh maxima site thing, the guy says his tire radius is 12.75" can that be right? he's rolling on 25.5" of tire?

 

i know someone wants to help me...

153mph at redline
or 167 at 8200 sum people take it that high

thats with a 205/55/r15

I think that this is off a bit because I remeber 177mph the top speed at 8200/8100. used to be on h22a.org. A guy ran his car on the dyno.

and I remeber using a different calculator at one time and getting 176.something

also I know I will get flamed for speeding but just chill.
Vtec hits at I believe 105mph in my car. so this calculator might be a tad off.

does anyone here read sport compact car? there was a technobabble a while ago about figuring this out. maybe someone could scan it or summarize it?

 

those numbers seem close i think.. i distinctly remember 2nd being around 60mph at least in my car...

 

check technobabble on sport compact cars website about 2nd gear conspiracy or 0-60 conspiracy.. good read

or maybe someone coudl figure out which issue it was and let me know?.. it's pissing me off not knowing if this is right or not.

 

I found this site from an old post: http://www.turnzero.com/techni...lator
