New Tire/Wheel/Spped Calculator, Avoids previous issues with web-based apps Options

[pvollma]

I originally wrote a calculator back in the 80's when I was autocrossing and fitting different size tires while driving the car on the street. This was a PC-DOS application that printed out a chart of MPH for each 200 RPM between 1000 and 8000. This app also allowed you to enter your torque curve (stock curves were available in the owner's manuals of the time) and the program would calculate optimum shift points, and, if you entered the car's cross-section (amount of square feet presented to the oncoming air and also given in the owner's manual), it would even calculate your theoretical top speed.

I then rewrote it in Java as an exercise in learning that language, and so it would be accessible on a web page. I never included the shift point and top speed calculations in the web-based app. Now, of course, Java apps are either forbidden (Chrome) or tough to get to run, so I needed something else to use, and to possibly share with other enthusiasts.

Here's my first attempt at a working app:

Gear Charting Application

For now, if you don't have a 914-4 or 914-6, you'll have to enter the Porsche gear sets manually, as they're not included in the selection listing. I hope to add many other Porsches as standard selections in the future. If you have a suggestion, especially on common standard gearsets, PM or email me. Also, let me know of problems you might encounter. The "Help" button will bring up a fairly detailed explanation of the program.

This app is written to be "mobile-friendly" so it will look fine on a smartphone or tablet.
