Turbos are rated in mass flow not hp. Looks like about 37-38lbs/min. For a simple hp calculation you can multiply the max mass flow times 10 to get a fairly close hp number for an engine that peaks power around 5500. If it peaks lower the hp will be less and if it peaks higher the hp potential will be more even though the mass flow stays the same. You wont see too many getting 380hp on an LC2 with one because the engine wont flow enough at 2.2-2.3:1 pressure ratio where the wheel is working its best for peak mass flow. It would take really good air to do it or at least a clean up of the factory heads and a good valve job. 280-300whp was fairly common. So about 340hp.
