I just want to know if they are worth it. I put them in my old maxima and it did nothing. I read that they slow down the water pump so it run's hot is this true?
get ASP alluminum, extremely light weight and you'll feel the difference.
The only prob. might be the alt. not charging fully, if that happens, just swap the alt. pulley back to the original....for the price, they cant be beat
I have run u/drives from day one...I have had neither cooling or charging issues in over 5 yrs...charging, the voltmeter drops at idle, otherwise its fine
Dyno results in most mags will tell you its cheap HP....8-15 is common, not alot,but none the less...its more sack...
