I have a 2001 mustang bullitt that I plan on supercharging. The car is stock except for the xpipe and dynomax exhaust. Can I run 6-9 pounds of boost on the stock motor or am I looking at motor failure? I will be using the torkteck kit with a stock cobra supercharger and injectors and all the other stuff that is needed. Trying to get 390 to the ground. I don't really want to put on longtubes until later. Will the car run fine wiith a good tune on 9lbs?
