I was watching a TV show and they mentioned adding a vacuum pump to increase horsepower. I have a bone stock L98 in my 89 6 spd. I have watched a few videos. But, they are running high horsepower engines at high RPM. I am wondering. With a stock engine does a vacuum pump generate any horsepower? Or is it just for high compression and high horsepower engines. Thank you
