Other than going through your gears while gunning it, how do you calculate the top speed for each gear.

 

it all depends on what size wheels and tires you are running...there are calculator around on the internet where you input each gear ratio, your final drive ratio, and tire size and it will spit out the speeds of each gear. I will look to see if I can find what I'm talking about.

 

Here is one calculator (have to calculate each gear indiv. though)

ok thanks. two more questions though. how do you find out the gear ratio for each gear? and what is the final drive for the 6mt....I pretty sure it is 3.5, I think.

 

Here you go...for both the 6MT and 5AT Guys

6-Speed Manual
1st: 3.794
2nd: 2.324
3rd: 1.624

6th: 0.794

Thanks again.

 

Anytime...

 

Better:

 

So it says I can hit 200.5 MPH with my wheels if I get the reflash......SWEET

 

It could be just wheel speed without any real life variables

 

Nice chart, but remember thats only good if you use the stock tire diameter.
