Message	exhaust concept idea for years. What if a vacuum pump was installed in the exhaust to help reduce back pressure. This could be most beneficial to turbo applications because back pressure becomes critical at higher boost levels . You could eliminate reversion and increase power. Now how you would run the pump would most likely be electrical. It would be like a reverse turbo. ************************************************************ "It's better to be dead and cool than alive and uncool" Don Johnson in -Harley Davidson and the Marlboro Man "Yes, I know more then JWT.
