With my Lightning I had a regular cheapie unit from Lightning Force Performance. I had to empty that thing about every 2-3 days. Depending on driving. I'm in boost a lot when I drive. It's too much fun! I finally switched to the L&S and never had to worry about it again. Great unit, not the cheapest but you get what you pay for. It works well and you never have to empty another oil catch can again. Vince's product is top notch! Now if he could just make it a little prettier.
