Are there any underdrive pully kits available for our engines? Idk if it makes a difference(I cant justify one) but I have an 06 2.2. I have seen them for other cars with adjustable cam timing pullies for less than $100 and they seem to give(free up) over 10 hp depending on the application. I had a set on my Z and they worked wonders with throttle response...

 

Not that I know of. Mrz makes a crankshaft pulley but it hasn't been dynoed yet.

 

Thanks for the answer, that is pretty gay though, I wonder if there are any pulleys for cavaliers we could steal...

 

check the vendors, if its not out yet it will be very soon. there was a recent post about it

 

Woo! https://www.cobaltss.net/forums/show...=1#post2841304

 

for search!!

 

You can't use UD pullies on boosted cars. On boosted cars they make a lower (crank pully) and and upper (supercharger pully) changing any of the others will lower boost.

 

Those are only for 2.2's and 2.4's.

 

We now carry them crank pulleys for 2.0 2.2 and 2.4
