Multiple Bypass Valves
 

At what point do you need to run 2 bypass valves? I currently have a Vortech MONDO Bypass, but am wondering if I need to invest in a second. Blower will be a YSi.

Yeah, I'm thinkin I only need one, but I've seen several cars now with two and it got me wonderin. Guess I'll see how well it likes having one, shouldn't be a problem. :)
