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

Seems very good. I don't know much about it's capabilities. Things like reverse calculations. We know very little when we see a race. Then we try to evaluate the vehicle. Years ago we would use a slide ruler. I feel like I'm back there with this. But I just need more information to get help from this. But thanks I appreciate the work to make this.

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.

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

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 more strange . . . Your website shows the correct Wheel HP.

Freaking love this app. I no longer need to have so many internet pages saved, most are all in this app. I do suggest a static compression ratio calculator, it would be nice. Other than that it think it's perfect.

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.

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 dyno operator mistakenly gave me a printout with STD correction. Now I can convert it!

While the layout isnt the best, its app provides ample information for me to improve. Thank you for creating it!
