[QUOTE="Ryushin, post: 6018910, member: 38551"] So according to whipple's web site, it seems that the supercharger is rated from 8-25 psi. So I would have to find a larger pulley then. My purpose of this thread was to try and find some information related to how efficient the twin screw is compared to a ported Eaton at lower boost. Maybe I'll just have to waste the extra $800 or so to get my Eaton ported and purchase a whipple on top of that. Then change it out. Maybe run 10 pounds of boost (though I'm only seeing 7.7 pounds at a mile high) and compare the two super chargers. From what I understand the Eaton is supposed to have to have a flatter torque curve and the twin screws make more up top but not down low. Also, since I'm being so protective of my engine, does anyone know of a knock sensor setup for the cobra motors that will retard the timing if it detects ping/knock? [/QUOTE]
