I don't see why this engine shouldn't produce over 400 bhp.
2.4 bar gauge with good intercooling will get around 465bhp at 8200 rpm by my estimate. The turbo is too big lower down the rev range - I don't think you would get much over 2.2 bar at 5000 rpm, giving maximum torque of about 340 ft/lb. Still a useful 320ish bhp at that engine speed.
But if you only want 380 bhp, 1.7 bar should do it - so the turbo has much more capability than you require and a smaller housing would have spool up quicker and be less laggy.
