Ive been tossing around the idea of running a vacuum pump. I have been looking at the pumps made by gz motorsports and they are just ford smog pumps that are modified. they improve ring seal and basically stop all oil leaks. is there any cons to running one? i have heard you can gain as much as 30 horsepower with one. is this true? and does anyone know anything else about them because i have never seen one ran on a 5.0?
thx in advance
