    I have been reading this thread on Ryan Baileys C18 which I have found really amazing. In the dirt track world we used to say Horsepower is how fast you hit the wall and Torque is how far you go through it. Now the question. Wouldn't the Torque of the C18 offer better drivability than the higher horsepower C15? I read once a very long time ago that it takes 262 hp to pull 80,000lbs. 55 mph. Now for theory's sake say 550 hp would get you to 110 mph. Which do we really want 110 mph capability of the ability through Torque to maybe run 75 all day long? I know there are many factors that change in this theory and I know which I want but not sure how to get there.

    Torque gets you there and horsepower keeps you there, 262hp might be what it takes to maintain 55mph on flat land but there are many hills across North America, its a juggling act between torque and horsepower and we have to combine this with mpg.... so what im saying is i have no clue

    I thought IMHO; that torque was the pulling force at take off, and HP was the power to reach top speed ?
    so HP would equate to wheels spinning at take off while torque takes the lead ?

    The lower gear= horsepower and lower torque
    Higher Gear= higher torque

    Google horsepower,torque, and horsepower vs torque. I just did. You should find helpful info there.

    Torque is the pulling force, HP is how fast you get there. In other words, torque= How much force it takes to break off a bolt. Horsepower = How fast you do it.

    Wow that's the best explanation I've ever heard. Something my brain can wrap around.
