I've broused through the forums and I have not found specific information relating pully size vs boost increase. Perhaps someone who knows could post this information.

I'm trying to figure out what is the biggest change I can make to the pulley and still use pump (93 octane) gas. I would also install a CAI.

Thanks

I only know of one aftermarket pulley available for the m62 (pre '96 SSEi'*) superchargers.

Go here http://www.scperformance.com/ then click "choose your vehicle" and then choose "Bonneville SSEi" and then choose "engine". It will be the last one on the list.

There was a post in the past that touched on this. http://www.bonnevilleclub.com/forum/...&highlight=m62

I don't have any specific pulley size vs hp gain stats but hopefully this will help.

Thanks for the reply. Looks like there is a significant difference between what is available for Series 1 vs Series 2 motors. Now I know what the guys with the older, non-intercooled Grand Nationals feel like. :(
