Motor math made easy!

[Bowtie]

I have found myself fiddling with paper and pen or searching the web for a calculator or spreadsheet several times lately. I am usually trying to calculate the preferred final drive ratio, tyre size or throttle body flow.

I have also seen several similar questions on the forum. I then start to search the web again only to find that the site has disappeared from cyber space or that I can’t find my way back to something I found useful in the past!

That’s when I thought that I should combine my computer skills with my Cobra building needs. Why not make a handy calculator and collect all useful formulas and also add some other nifty bells and whistles to support me?

Said and done! I have now made a first, so-called beta version, of the Motor Math calculator. I have added functions for wheels/tyres, transmission and induction. I am planning to add additional functions as soon as I stumble over useful formulas or if I get any specific requests.

The program is primarily written for my own usage but I will share it as freeware with you all (usage at your own risk). You might therefore, from now on, run or download the latest version from the following link: http://hem.passagen.se/robert.palmqv.../MotorMath.exe

There is no installation needed, just download and double-click the file to execute it. I find that handy so it might be carried around on a floppy to be used on any Windows PC without the need for an installation. Just click and run!

I would be really happy if you could provide me with feedback, is the calculations right? What could be made better? What additional formulas could be added? Etc.

I especially need information from users with overloaded engines (turbo or super charged), how do you usually specify the degree of overloading? Boost (PSI or Bar?) or percent? How would you like it to be specified in the application?

Feedback might be sent to me at the following mail address: robert.palmqvist@home.se or click on the mail address in the applications about window.
