I use this app all the time! It's quite useful to calculate estimated drag times based on weight & horsepower. There are loads of car math that this app can do.

Way cool App This is so cool Rob! One way it's useful for me is that to compete with my S2000 in the Porsche Owners Club I have to class my car based on power to weight ratio using SAE correction. The Dino operator mistakenly gave me a printout with STD correction. Now I can convert it!

Works very well The only thing I've found that's off is the flywheel HP from wheel HP calculation. For example if you put 80 in as whp and 20% drivetrain loss it gives you 96 flywheel HP while it should be 100.

Adding 200# to the curb weight the app is very accurate for most IC cars. More expensive German brands often show more hp than advertised, maybe to hide it from the Green Party as US hot cars' sis before 1973. EV s usually calculate much more than advertised, so may need revisions for EVs.

You may want to reconfigure the HP calculator. The HP calculator from ET and MPH tries to give Flywheel HP but without knowing the exact % of drivetrain loss that's an arbitrary number. 5 other online calculators show me 270HP at the tires, which is correct but this app shows 270 at the flywheel? I think not. What's even stranger. . . Your website shows the correct Wheel HP.

How can you calculate all the stuff, like Horsepower, without knowing the weight??

Calculates CFM using the engine size in cm^3 instead of in^3. No option to change units. No GPS functions.

Major scaling bug Using a nexus 6 with Cyanogen with the default dpi. Unfortunately when I open this app, everything is so big it doesn't fit on the screen.
