[QUOTE="03LCalgaryAB, post: 7724678, member: 48338"] So I did a little more research. I cracked open a Truckin issue back from OCT 02 and they did some pulley swaps on a L with a KB. (Wow, looking back, the Truckin issues are so much thinner now) 7.5" lower & 3.0" upper = 13.2psi 9.0" lower & 3.0" upper = 15.8psi 9.0" lower & 2.75" upper = 20.6psi 9.0" lower & 2.57" upper = 21.6psi There is also a boost conversion chart. Potential boost = Blower displacement x drive ratio ----------divided by------------ X 14.7 - 14.7 1/2 of Engine displacement The ex. provided is a Eaton M112 (112ci = 1.84L), 7.5" lower & 3.0" upper Pot Boost = 1.84 (7.5/3.0) -------------- x 14.7 - 14.7 1/2 x 5.4 = 4.6 ---- x 14.7 - 14.7 2.7 = (1.70 x 14.7) - 14.7 = 25.04 - 14.7 = 10.34 psi* *The difference can be attributed to inlet restrictions. "It also states that this equation can be used for any positive-displacement supercharger, including the Autorotor from Kenne Bell, a Whipple Charger, a Magnacharger, and even an old GMC Roots-style 6-71 blower."
