How does cid make power?

You missed one Rob. Horsepower is NOT the result of torque. It never is. It is the result of torque and RPM. You can have all the torque in the world and without RPM you have zero horsepower.
Crap! Missed that one? I thought I made some sort of mention or something. Tiring day. I’m done driving in the car today.
Thanks to the wife I could reply as I was the passenger for 4+ of the 8 hour trip. My eyes had enough after a bunch of rain and early traffic.

I got one for you….

How does one measure engine torque without the piston moving?
