I can tell you. The engine runs at 2500 rpm and wont go any higher. You level off at 400 ft, do a quick return to the field, cut off a Cherokee on downwind, turn a tight base and dump her back down. No problem. Underware intact. Gotta get a better fit for those turbo pipes!John Slade (turbo runs just fine when connected. Thanks, Rusty).
