Vac pumps???
This is kind of weird question. I went to a terminator this year and decided to go with a Moroso 4 vain vacuum pump. My reasoning was to get a little HP gain and keep the oil from milking as bad as it might without the pump. Yesterday a good friend that runs a blower and has been very successful in his racing career, was at my shop. His opinion was that the vacuum pump would only rob HP not increase and that a good Evac system with large enough ventilation would work just as well. I didnt really have an answer and Im not educated enough on the vac pump to argue. So hears my question to you:
Does the vac pump produce more HP over a good E vac system and Why? And does the vac pump keep the oil from milking as much on alcohol as a good E vc system and Why?
