what is the minimum turbo size I would need to light a GT55 in a compound setup? pretty sure i would need an S400, but am wondering if my silver 66 could light it and not be to laggy.
How much air needed to light a GT55

If I can get my hands on one, I will run it as a single. 
You need to know the RPM and boost range you want first, then pick the chargers second.

gt55 as a single? think that might work well with the 7.1L kit? read that the gt42 magnum from ppe may have been a little small for a single.
Don't be scared. A person could light a GT55 as a single. A .90 exhaust housing and a some RPM. 75 psi... oh, Hi!
As far as compound, a ~70mm S400 would do it easily.
