I finally got this procharger D1SC running on my 502. However, although it sounds good after a dozen setbacks, my boost gauge is reading about 12.5 at idle......I dare not gun the thing as I don't want "ka-boom". However, just slightly revving it, the boost remains fairly constant at 12-13 pounds. The problem is that I specfied to ATI that I want to run only 8 pounds of boost. Is this a problem? I have my boost gauge hooked up to the large vacuum port on the rear of the carb. I'm going to call them tomorrow, but their tech support is less than great. The diameter of the D1SC pulley is approximately 4 inches.
