I've got the 3" on my 6.0 with now making right at 6.5-7lbs.

I'd like to get the boost back up to 10-11lbs.

I'm thinking i'll need the 2.7x?

But will i need a new belt to prevent any slipping?

Please confirm the pulley size i need and about the belt size.

thanks,
chris

check with whitt1, BLOWN364 or BigTex, they are all running small pulleys.

I now have a 2.8" pulley and am using a gatorback 110.75" belt. I saw no increase of boost going to a 2.8 from the 2.9 on MY SET-UP (6.0L LQ9). I am sitting at around 8 to a little over 8psi. Keep in mind I have a cam and a full exhaust which hampered my peak boost levels.

I have heard of people with the LQ9 using a 2.9 and getting 10psi.

sounds to me like there might be too much overlap on the cam.

what are the specs on your cam?

I'd be surprised by 10 psi... Perhaps nine or a little over?

cam specs for me 214 / 222 .559 / .566 on 115LSA. (not the ideal blower cam, however not the worst).

On the 10 PSI thing from a 2.9 (on a LQ9), that is just what I heard from some people...I have not had the same experience.
