Algodoo

Wow! What a revolutionary discovery!
For me, that "engine" may be good for small cars that weight about less than 500kg because of its low rpm. But we can increase the torqe( torque > rpm ) by adding gearbox.

It just goes back and for bro.

So Pnvv you should attempt to measure how little the power this has xD
Also, how do you find out and measure the power in engines and such...?

I usually use this handy converter.

But when I don't have time (or my internet is down, or I'm too lazy) I do this - measure torque then pause scene when you get the highest reading, then take the angvel of your engine's flywheel and multiply it times 9.5 (the actual number for the rad/s - rpm conversion is much longer and uglier but 9.5 will give you a fairly accurate estimate. If you want to have a 100% accurate conversion, use this). If you don't want to convert NM to ft-lbs (which you can do here) then take your speed (In RPM) times your torque. If your torque is in NM then divide the resulting number by 7124, if it's in ft-lbs then you can use the calculator at the top, or just divide by 5252. I know that sounds a bit complicated, but I hope that helped anyway

rad/s * NM = Power in watts * 0,00136 = Power in HP is what i use to get around most conversions:p
