this question has been asked many times. Search. 15 would be pushing it and the most power would maybe be around 340 to 350 whp on a stock motor.

The stock twins will boost up to 18 psi or so and make up to 380 HP. They obviously won't last very long maintaining that level of boost for any length of time. I have run mine up to 15 psi at the drag strip and they seemed to hold up well. It really depends on how reliable you want them to be. Anything above the designed pressure (10 psi) will shorten the life. For street driving I wouldn't recommend going any higher than 13-14 psi.
