Well, I can't answer this. I'm pretty new to the MT world.
The only way to check the difference between the 3200mah orion and the trakpower is to use the eagletree bywhich you can measure the amp rates, watts and voltage.

Also, if you have a radar, you can check the speed of your truck with both the trakpower and orion's cf cased 3200mah pack.

Ofcourse, according to the specs of both packs, the trakpower has the upper hand easily and you'll surely feel a difference in power and speed.
