Greddy type r bov - how to tell which spring it has?
So I just picked up a Greddy type r bov and the seller was unsure of which spring it has.. how can I tell whether it's a standard or stiff spring unit?
Google was worthless for what its worth

Well I disassembled it to check everything out and here's a picture of the spring
From what I can gather it looks like the standard spring given the coil thickness... however everything I read says pressure levels above 22-25psi require a stiffer spring.... any truth?

That's theinstructions and descriptions, you know its hard to gauge power levels based upon boost pressure, but the point is the the stiffer spring is for larger turbos with a lower vacuum.
I'm already at 25psi with this standard spring on 58lbs/min, and its fine. at 47mm valve size, it won't surge. Just use it already.
