horsepower hill

Any large, hillclimb that requires skill and brute hosrepower to successfully negotiate.

We went to Dove Springs and saw many riders attempting to climb Horsepower Hill.

Just about every motorcycle riding area has its own 'horsepower hill'.

Mental Horsepower 

When you personally have made a repair to a machine and feel that it works better just because you worked on it. Even if the part of the machine you worked on would not make it work any better.

Jim: "I replaced the heater core in my car, now it seems faster..."
Sam: "I've heard of that before."
Jim: "Seems to run smoother too!?"
Sam: "That's Mental Horsepower!"

Don't leave horsepower in the showroom 

A metaphorical rule to live by: don't make the mistake of choosing the cheaper option to save a buck in the short run, when you'll curse yourself later for not getting the better-grade product/service in the long run.

Eric: "What was I thinking buying that Porsche with the V-4 instead of the V-6 -- it handled like a Formula 1 car but is a total slug in a straight line!"
Tim: "Dude, you broke rule number 1 -- don't leave horsepower in the showroom."
And so --
Maddie: "This well Margarita sucks -- why didn't I get the Cadillac for two bucks more?"
Amy: "Exactly. Don't leave horsepower in the showroom, sweetie."

Horsepower

Horsepower is directly related to torque. With a low torque output, you will have a low horsepower output. Torque will start higher in the low RPM's but will always cross with horsepower at 5252.

Horsepower = (Torque x RPM) / 5252

Check out that car, it has so much horsepower.

No. It has a lot of torque.
