underdrive pulley

[rhinojohn]

just curious about the gain from going with the 25% underdrive pulley i see available?

Less than 10 rwhp and some better gas mileage most likely.

not sure but i can say its a good mod. i have LTs, CAI, exhaust and UD pulley and put down 370 rwtq and 365 rwhp with an m6......usually CAI lts and exhaust get you around 345-355 so im going to venture and say 10rwhp is a good estimate.....also easy to do yourself if you have the right tools, should only take about an hour nd a half

I have the asp set with the alt pulley since I have a A4 gives you about 10 HP and took my friend about 30 min to install. G

U/D pully should only take about 30 minutes lol (with a puller.)

normally the U/D pulleys are good for 10 HP on the dyno if that is the kinda thign your lookin for!
