water pump underdrive pulley

in a post i put up about three weeks ago i asked what is the most hp i could get out of an L36 and someone told me to check out the kit made by ZZP that would supposedly put me into the mid 15's i did and now i need to know if i water pump underdrive pulley could possibly cause me to over heat when i am driving 400 miles back and fourth to school. any help would be appreciated thanks.

if you could also tell me what exactly a 5 % underdrive alternator pulley will do. sorry for these more than likely stupid questions.

I have no problems w/ overheating w/ my wp pulley from zoomzoom. Alttle slower water pump can actaully help with heat transfer.

The 5% underdrive pulley is going to spin the alt. slower, which is supposed to free up alittle power.

I use a 10% overdrive (i think thats the right number, been awhile) on my alt. Helps keep the battery charged and volts up with my system. I also get no headlight dimming that you would experience when the bass hits hard.

kick ass thats what i need to know ripn12's thanks
