Anybody know the equation. I want to make my own program and don't know the calculation
Go to www.4lo.com. He has the downloadable calculators that he says you can use on your website. Hope this helps.
They have one here to http://www.ring-pinion.com/home.shtml
do you have Exel?
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.
