    SN93 Troubles

    Hey guys, this site has been a great resource. Pavement pounders how to rebuild was great as well.

    I have an 83 GT that has a built 306 8.5 to 1 compression, edelbrock heads, weiand xcellerator intake and a holley 750 carb with a SN-93. Everything is great with the head unit, I have (2) upgraded impellers, one that is ceramic coated and one that is not and the blower with a cog setup totalling 10.25" only produces 5 lbs of boost @ 5000 rpm. Does anyone have any ideas. Also does anyone know what I should be running for fuel pressure. I have a boost referenced regulator as well. I was hoping to see atleast 7-8 lbs :(. Any help would be appreciated.

    Not sure what 10.25" cog means as in reference to how fast your spinning the blower. What inlb torque do you have the pressure against the balls and the impeller shaft set at?
