Thread: DISPLACEMENT OF A ROOTS BLOWER

I suggest you get a text book quality manual and read and absorb thoroughly before starting. If you are going to use boost levels much above 6-8 psi over atmospheric, then you are in for an interesting ride both in the car and on the tools.

Thought it was 6-8 psi Brian, there is a whole host of posts from yourself about how difficult it is, I hope to see a very concise build up thread
