Went to the dyno last week and it made 409rwhp & 503rwtq, with 383 cubic inches, GT40 heads, Cobra intake, S-trim with stock 3.33 blower pulley, 10-11lbs of boost on 91 octane, I would say the GT40 heads and Cobra Intake was holding the motor back, but it made 150+hp & 200+tq than a stock 95 Cobra R, so I guess it's ok.
