Based on my site searches, no one appears to be using the Vortech YS-trim, except me. And, yes, it will fit under hood.

 

YS w/cog here.

 

We're still running the 8-rib belt and haven't found anyone with cogs for the LS-1. Where did you buy your cog pullies?

yea, they responded in an email that they had nothing for an LS1. We're running a hydraulic cam around 6500 rpm so slippage has not yet become an issue.

 

Might try Vortech-the C5/Z06 kit comes with a cog.

I too am running a Y/S-trim, it is by far the quietest of the superchargers I have run/heard in the past. I am running a 50mm cog setup from ASP, they can custom make just about anything. You just have to take the appropriate measurements for them to work with.

 

could someone explain to me about the trim...im new to that kind of stuf...it might sound stupid but i really dont know

I am also running a YS-Trim
ran a 9.49@144 first time out on a ribbed belt 12lbs.
Now running the cogs waiting for warm weather.

 

I spoke with auto specialties and they can make us a cog setup. We hope to make the 8-rib work by shifting at 6,500 with an
8-inch crank pulley and 3.12 blower pulley. If not, we have plenty of room for the cog.

It turns out that all I had to do was ask, and the "YS" guys came out of hiding! If you guys can run mid-9's on just the YS, we may have shot at 8's with the nitrous express setup. Whattya think?
