how much hp do u think this supra is running?

1994 TOYOTA SUPRA Turbo - 6cyl Rare Silver 2DR Coupe, 8k Miles on new engine and new turbos, Automatic Transmission, RWD, 6 Cylinders, Excellent Condition. Greddy catback exhaust, HKS evcIII booster controller, K&N air filter, Cusco Sway Bars Front & Rear, factory chrome wheels with new tires, Hwy miles 149k other extras include brand new front/rear brake pads and caliper rebuild kit

350whp-375whp depending on boost.

im guessing 380-385, all depends on boost.

320 stock, openned up exhaust, maybe 10 extra horse. I'm going to be more conservative about 330 - 340 horse at the crank if running stock boost.

340-355 rwhp, unless he has the rubos boosting to much. I am against huge PSI with the stock turbos, also a little power is lost since there are so many miles, and the auto tranny looses more power than the manual.
