Well the engine is huge, so it's not so simple, but it has more than 60 or 70 hp for sure. It is 4x11 mts size xD
I've tested it at 100 Hz, scene.my.power=6; in s_noonan's "Torque vs rad/s" scene (or whatever) but the Nm limit was too low, so it couldn't measure the total torque/power

But I like the scene. I still think that you should make everything 11 times smaller (literally) because everything looks like in slomo, and you should use easier controls, for example, the ' key is quite weird in my keyboard (i guess it's some generic Spanish model).
9/10

ah yea you are right although i do have a reason for my insanity. for example the size is just so i can easily see m/s as mph and the ' key is right next to my enter key on my keyboard so when i start the engine i essentially press both keys at the same time which is easy to do since they are so close together. ive been thinking alot about changing the size tho especially since now ive started using my own speedometers instead of the velocities tab u get by right clicking. Thanks for the comment!

If you make the car 10 times bigger than in reality, then you'll have 10 times more speed than in reality, you know

yea its so m/s looks like mph without having to convert it

Its not very difficult to convert the Speed...
Just use this website...

Also, 1 m/s = about 2.2 mph, so if you wanted speed in mph than why didn't you just make it 2.2 times bigger than normal?
