This May Be The Wrong Section, But This Is A Feeler Thread For Mrz To Make An Underdrive Pully For The Ecotec Motor, Lsj/lnf, 2.2, 2.4

Who Would Be Interested?

 

I think they had tried this previously (a while back) and no one liked the idea of an under drive pulley. Only lightweight OEM size.

see if you can search and find the thread and may be do a revival. lol.

 

Haha, I'll Look, But Hey, I'd Go For A Lighter Oem Replacement

I wouldn't buy an underdrive pulley for my car. If anything, I'd want an OVERdrive pulley, to push the supercharger faster.

A lightweight, but OEM-size crank pulley would help rev the motor faster, but you generally don't want to go smaller on a supercharged car, unless you're severely over-revving the blower.

 

changed the title, maybe they'll give some options

 

I would definately go for a lightweight replacement for the stock pulley.

 

yeah i like the idea of an oem lightweight crank and alternator pulley...

 

I'd recommend this company, and here's a GB:
