etec-II underdrive pulley development

[y2dgone]

I dont know if or when I'll start making them again, if they are bought individually of course the price will be more but I can't give you a quote right now because I don't know material prices, it'd take about a week to get one done, if I do decide to start this again it won't be before August, right now powder coating will not be available because the guy I used is no longer doing it

[thehunterooo]

august eh, sounds good, group buy time!

[reddemonx92]

Im in too for the group buy it gives me enough time to rack up some more mileage to get closer to the 60k mark for my timing belt change. might as well do it at the same time. less hassel that way

**** you have to change the timing belt at 60k My 2007 has 92k on the stocker. I did change my serpetine at 87k and that was trashed. I have xiagarys crank pulley and along with power I get like 2-3 mpg increase during normal driving. The stock crank pulley is so heavy. Its easy to remove. I used a regular socket wrench and socket along with a 2 foot metal pipe that I slipped over the handle of the socket wrench in the 12 o clock spot posistion and rested the pipe against the motor mount. I then cranked the car as if I were to start it for like a split second not long enough to start the car and that got the bolt off. The pulley is probably one of my favorite mods I have done with my car along with the 225 pounds of weight reduction.

oh, cool... bunch of lines... how bout a legend or an explanation? I take it the one above the rest of them (blue one or something) is the one with the pulley?

Oh sorry, lol

In the top box is the horsepower and torque, but I'll be honest I forget which set is which lol. Bottom box is my a/f ratio, yes the top blue line is with the pulley. If I had some sort of a/f management at the time a lot more power could have been had.

The best thing I liked about the pulley actually wasn't the power gains, it was the fact that it tightened up the steering some, I always thought the Aveo's steering was a little loose for my taste
