Ways to reduce friction

[newyorker_79]

I noticed a huge difference in rolling resistance this winter, just adding ice scratchers. It didn't seem to have near the harsh decel, when letting off the throttle. Obviously reduced friction. Plus, my slides lasted longer.

These Slidekick scratchers have been the bomb for my on my Attak!!!!!!!!

Horsepower isn't lost. Horsepower is simply a measure of how fast a system can do work. Mathematically, at a constant speed and load there is no horsepower output because the rate of work is constant - its derivative is zero.

As the mass (inertia) and friction of a system increases the rate at which work can be done decreases - given a finite energy source – thus the lower horsepower rating. Reducing friction between moving parts and inefficiencies in torque transmission will help, but only marginally, maybe a few percent. My earlier point about the track was that it requires a great deal of energy to move, but as long as we want a snowmobile there’s not a lot that can be done to make it more efficient.

Reducing the overall mass of the system is the where the biggest gains are to found. Consider that 25 pounds moving parts in the motor must propel 700+ pounds of sled and rider. Obviously the rate (work as a function of time) at which this can be done must be less and thus the lower hp numbers.

Doesn't Arteeex surely believe he is pure genious!!!!!!!!!

And as my fiance always reminds me...... Friction = Bad

You neglected a term in your equation.

Friction + Mike = Bad

I think I need to keep my fiance and you apart, Mr. Arteeex!!!!!!!!
