I've got a '94 GT with a 347 (Victor Jr. heads, carb style intake) with a Procharger F1-R and a 83 tooth crank pulley/54 tooth blower pulley combo. Pretty similar to an NMRA drag radial setup, just a little more mild.

Has anyone run a similar pulley ratio to this, and if so, what was your boost level? I haven't run the car yet, but I'm just curious as to what I should expect, as the old serpentine belt pulleys were about this size, but I only saw 12 lbs. of boost.
