In Reply to: Underdrive Pulley to add 9 HP? posted by Chris_P on March 09, 1999 at 11:32:32:

European Racing Technologies also offers an Underdrive Pulley and they claim (on M3, at least) 12 hp increase and torque increase of 23 ft-lbs. With Supercharger, M3/M Coupe will see 13-15 hp and torque 25-28 ft-lbs. ???? I am not sure about this...

They have product info on their site. Check out ERT web site.

Anyone actually use one of these on their M?


: Has anyone heard any feedback on this new accessory from Turner Motorsport? They claim 9 hp gain with no negatives... Any thoughts?

: Here is the link (About half way down on the page)
