Cant seem to find the answers im looking for.. so maybe i will get them here.

Im getting a UDP as soon as i can, my question is is it worth buyign the whole kit or just the underdrive pulley? I live in canada and it doesnt get too hot here where i am, the only time my engine may stand any chance of overheating would be when im in the bush for hours on end. I dont have a system in my truck, just an aftermarket cd player.. which shouldnt be a problem.

Any opinions from people with JUST the UDP?? how has your truck held up offroading as far as overheating goes because you dont have the water pump pulley too?

Thanks

 

if you get the water pump pulley, it will slow it down even more.

crank pulley is where the main power comes from. Thats all you need.

 

yea thats what i figured, just didnt wanna have overheating issues like alot of the people in the threads i have read have.
