I was wondering if torque for speed for track is better for powder I have a 146 wondering which would be best to be able to push the snow especially in sticky snow
better for powder? speed or torque?

If clutched correctly you should have both.
Make your clutch settings so the engine achieves rated rpms.

Concise - The sole purpose of clutch tuning is to clutch tune in such a way that the engine is held at its power peak all the way from low ratio to high ratio.
An engine has a range of maximum torque spread through a small range of engine speed. Common for example a stock 800R engine has a rated engine speed of 8150. Torque point is 7750.
Here is another issue. The more time you spend at full throttle, that heats up the exhaust pipe to its equilibrium point. The pipe temperature will "move the hp peak" from 7750 to 8150. The clutches will perform best at 8150 while at full throttle. Now when there is a load variation seen at the drive axle, the engine can pull down speed to say its 7700~7750 peak (still at full throttle) and have the ability to recover engine speed back to 8150.
If you were to clutch for peak torque at 7750 and now encountered a load that forced the engine to lower speed, the torque will reduce in amount quickly while engine speed reduces, the rave valves will close. The engine speed will be low enough it cannot move the cylinder charge fast enough. You'll never recover the engine speed back until the load seen at the drive axle lowers, hence slowing the sled down, reducing throttle or turning out. The load has to be reduced to an amount where the engine can overcome it at the speed it's running at.
