twin screw, 6 psi, non intercooled, black or polished finish, claims 442/525 $3950
Some of those you can get for different prices depending upon where you shop. I listed the lowest prices I could find. Most of the lowest prices came from here. After looking at the choices it will come down to an intercooled Vortech or the Whipple. I'm leaning towards the Vortech. I think I could up the boost on the Vortech and get huge gains where on the Whipple you are pretty much stuck under 10psi.
