Bruno, I don't know how much you want to spend but I called Jegs the other day to price a complete Aerospace Engineering vacuum pump set up for a friend. I was trying to find the racers dicount price for it. Anyway the price was $815 & there wasn't a racers discount. One thing I do recommend if you get one is an air-oil seperator. I had to put one on my car because I kept getting so much oil in the pump. It would cause the vanes to stick.
FYI- I also priced a Moroso 3 vane set up from Summit's Pro Shop & it was about $840 w/o air-oil sperator & about $925 with it.
Hey Bruno , a guy told me that one of the newer Lightning trucks uses a vacuum pump that sells for around $100 or so that pulls 14lbs of vacuum .He'd used them and they worked great. I'd say it's one of the supercharged ones?? Anybody know for sure?
