or does anyone have it already, if so how does it work? BTW click on the cobalt for vehicle and the pulley will be on that page.

I've heard they offer so little extra power it's generally not worth it

what about the price to gain ratio..i bought the B&M for 44$ and its not an incredibly huge gain but its damn fun.

BLK SS/SC

contact them and see what gains you should see
**** if you get 2 hp for 40 id say well worth it

i dont bealive theres much of a hp gain...i bealive its sposed to help you rev up quicker due to the lighter weight

07BluBalt

yes they say quick revs, but quicker reving leads to quicker acceleration, so they claim. i have a friend who owns a beamer and he has heard that upgrading crank pulleys is like one of the first mods that most people do to there cars. wasnt sure myself so just looking for the real knowledge.

what engine is that pulley for?

07BluBalt

id assume 2.2/2.4. i know ive seen someone on this forum link that pulley before and i know he has it installed.

do a lightweight crank pulley does lightened the load on the crank for better revs....but it would do alot better if u also added a lightweight flywheel at the same time u would see the full gains from the quicker revs this way....as the crank pulley itself wont help that much...the flywheel is a different story

wisemanonice

I think it is a good buy. do you know where I can get one for myself?

Considering the price of this one: http://www.crateenginedepot.com/stor...leys-C135.aspx


I would look into it. On the other hand the price difference may be something to worry about? IDK

i remember when this first came out from CED and everyone said the price to power ratio was dumb, $40 seems really cheap, maybe too cheap..

They aren't the same thing though. Then one on CED is billet to be stronger, the other one is a lightened aluminum pully. One is ligher one is stronger. The price difference is alot though, but they also don't do the same thing......
