Default Rollout Companion

Here is a little app for calculating rollout...



Download

I compressed it with 7-zip so it does not give .exe warning for those using certain browsers like Chrome

You can uncompress with 7-zip, winrar, or winzip

If anyone needs help please let me know

Then just use .exe as usual

Enjoy

Am I doing something wrong, or does the decimal point not work in the app?

I'm guessing you mean the input decimal for tire diameter so tires that are 40.55, etc can be entered

Here is a new build fixing what you pointed out Thanks for testing Andrew



Download

You can uncompress with 7-zip, winrar, or winzip

If anyone needs help please let me know

Then just use .exe as usual

Enjoy

p.s. Everyone ditch the original one I posted and only use this one since it accommodates finer rear tire diameter size's for rollout calculation

Very cool tool. I hope I didn't sound ungrateful.

Not in the slightest, rather quite the contrary I'm grateful for I might not have noticed the decimal bug for a while

What I like about it is it self adjusts without having to start over or have the internet availability

Thanks for testing

Later Andrew

Fixed some other things...

* Fixed arrow key behaviour
* Fixed ctrl+v which would allow text to be pasted in

I'm assuming that the internal ratio is fixed? if so, what is it?

The Rollout Companion is for pancars only so the formula goes like this

Pinion X Pi (3.1416) X Tire Diameter (mm) / Spur = Rollout

Rearranging the equation to get spur is also a useful tool, especially for oval racers. You see it a lot in the pan car threads: people share what tire diameter works best, what spur works well, and a range of target roll out, but never which pinions work with that combination to get into that range!

When you go to a track or get a new car and have a known wheel diameter, known spur, and a known target roll out, you can plug in the constants and get your target spur without having to guess. That especially helps newbs get into the right range their first time out.

Rollout x Spur / Pi (3.14159) / Tire Diameter (mm) = Pinion

I guess there could be radio button's to select what output is desired!

Either Spur, Pinion, Rollout or Tire Diameter with the Pi variable being silent/constant of course

I will think about it but others tell me how much this is important as an overall tool for pan cars?

I will also think about putting it into inches if that would also be important i dunno

Thanks

You don't need to do anything to put it in inches other than take the "mm" out. If you input your tire size in inches your output will be in inches. If you input your tire size in mm, your output will be in mm.
