Heyall. I have the prototype 1.6L Ecotec Underdrive Pulley that we acquired backin 2008. I haven't been on here in forever and we were cleaning out the shopand found it. Back in 2008-2009 we ran a limited quantity of these and theysold really well. It actually took me a few days to remember what it was for,but we have both the pulley and the matching belt.
It's machined from aluminum, so you not only getthe underdrive characteristics, but also the weight savings.
Looking for $90 plus $10 shipping.
I thought I had pics, will take some tonight.
