    Hey,
    Go to www.4lo.com. He has the downloadable calculators that he says you can use on your website. Hope this helps.

    I have looked at all there calculators. I still want to make my own. Just to do it I guess. I'm working in visual basic 6.0 and just need to know what the equation is. Thanks anyway.

    MPH = (RPM X Tire Diameter)/(Gear Ratio * 336)

    RPM = (MPH X Gear Ratio X 336)/Tire Diameter

    Gear Ratio = (RPM X Tire Diameter)/(MPH X 336)

    Tire Diameter = (MPH X Gear Ratio x 336)/ RPM

    OK got a program finished. It takes tire diam and converts to circumference. It takes transfer case ratios and multiplies them if you have crawl boxes or a doubler and then you tell it trans ratio, axle ratio and RPM and it calculates MPH and crawl ratio. Now if somebody has a full copy of visual basic 6 I can compile it. otherwise I guess i will have to wait until Monday. I only have a student copy. Anyway, when I get it done I will post a link and you all can test it for me and give me some feedback. My first venture into programming. So fricking bored, waiting for parts.
