At idle in 120 degree temp? I bet it would be the same with or without the UR pulley in those conditions...DanTheMan said:Underdriven means not as large aside from light-weight.
The accessory "rumor" does apply to my a/c (when I run it in summer) here in AZ. It's fine while rolling but if you stop and idle it warms up and is useless.
The compressor is fine, I had it checked.
The charge level is perfect.
Like I said only at idle and only in this desert (120F).
So much for "myths"
The pulley that is "experimental" is prob. too underdriven and may drain your batt.
But they are great for more horse/accell and wouldn't trade mine for a nos kit. (just don't like nos, engines are expensive, I know "if you do it right" it might last 100k mi and some will say "oh that's great mi for nos" but just try to trade it in now! haha)
