I'm still learning, and love every minute of it, can someone give me an easy explaination: What is the difference between crank and wheel HP? If we have 225HP is that crank or wheel?

225 is crank. 225 - 20% or so is then your wheel HP.

Default hp numbers are almost always given at the crank...

unless you are looking at dyno sheets. those are at the wheels because that is where they are measured. The loss from the crank to the wheels is due to the parasitic loss of the transmission and drivetrain.

I wondered about the loss, that's what I figured but wasn't sure, thanks.
