Stillen Crank Pulley
no word on official performance increases?
I'm surprised UR or STILLEN haven't specified anything yet especially since all the testing has already been done since the product is already in production.

UR pulley
UR's site gives 1 to 2 mpg for the crank pulley and 2 to 3 mpg for the whole set. They also state roughly 2.7 hp for each lb. removed. Their pulley's roughly 3lbs. lighter than ours the math looks good but I doubt that much. There dyno for a Maxima 3.5 shows 9whp and 11lb.s of torque. Just throwing that out there for fun. The Maxima is the closest thing currently listed on their dyno's

For those who already have or have had this kit on other applications, did you ever experience any electrical power loss, or electrical current fluctuations? ie. dimming interior lights. Any detrimental impact on A/C etc?

If the diameter remains the same on the accessory pulleys you shouldn't loose any A/C or power performance. If they are smaller diameter, like some of their kits, then yes you'll notice a difference. I already order over a month ago from UR and they told be they should start shipping this week. Plus they are $10 cheaper then Stillen for the same pulley
