Re: [DMCForum] Re: Dave Stragand's HP



There you go again *sigh*.

What you mean is that an engine that produces 200hp at 2000rpm is doing
it by putting out a hell of a lot more torque (50% more in fact) than a
300hp engine that produces 300hp at 4000rpm But what engine that
produces 200hp at 2000rpm isn't capable of more at higher HP?

At the end of the day, it's all about energy transfer. To go faster, you
need to transfer kinetic energy. Horsepower is a measure of how quickly
you can transfer a given amount of energy - therefore, higher HP
*measured at the wheels*  = better accelleration.

Bill, look up the "Venturi" - French supercar using a 3 litre twin-turbo
PRV with 24 valve heads. Nearly 500hp
