Ok, it took me a few days, but I've got it all up and running now. The calculator will figure out total gearing in a gear and maximum speed in a gear. It then plots all your ratios and shows in red where you will be if you redline each gear. Give it a try (S2000 ratios are built-in as sample data if you click the button at the bottom).

AWESOME WORK!!!!!!!!!!!

 

Thank you! I just realized I forgot to label the axes on the graph, so I'll do that now

 

Dude,

Nice Job. Looks much closer now. However your results could improve a little if there was a conversion from the theoretical tire radius size based on the tire size, and the actual rolling radius. I think you'll find that the tire actually rolls about 3-5% more times per mile than just going by the tire size. See the chart at http://www.bridgestonetire.com/products/s03pptec.htm
and see if you agree.

Also, isn't the redline of the S2000 8900 RPM?

You also might want to change "RPMs" (revolutions per minutes) to "RPM" (revolutions per minute).

Nice work! Sorry you have someone like me who can't do make an online calculator, but tries to help make it perfect.

great work!!

Thanks for the feedback. I will definitely take a look tomorrow at what is a good amount to factor in for tire deformation and I will add a checkbox to select that option.

Also, for those that haven't noticed, I caught a small bug that was throwing the measurements off a bit. It's fixed now. Tomorrow I will be separating the fields for axle ratio and final ratio.

 

thanx buddy

None of the default results jive with numbers I have been using. Does it comprehend the secondary reduction gear?

I do want to add a conversion for tire deformation, but I'm not sure what the best way is to go about that.
