Bill, I tried this with both wastegates hook to a common line from a regulator. The longer spring seemed to crack the valve open about 1.5 psi over the shorter spring/wastgate, so .9 bar. I also measured the wastegates to see if the cap and compressed length of the spring were the same, and everything was identical. Perhaps it's a .9 bar spring, just seems like an odd increment.
That's how I would have done it. I'd say you have a .9 bar spring there. Is kinda odd, but this test doesn't lie. I wonder if these are the same psi numbers a 1 bar gets so it's really a .9 they just call it a 1 bar cause that's the next incement. I've never heard of a .9 bar spring either. The performance catalog I have right here says the 1bar is 20% over stock and the 1.2bar is 33% over stock.
