I was going to wait until tomorrow, but I couldn't stand the suspense any longer. I got home at 4:30, and had everything in at 8:30. Tank pressure was 60 lbs. I cranked the needle valve one turn, and took a quick run to see where the Hobbs switch was set to come on. It was activating at 9 psi. I think 5psi is reccomended, but I decided to go ahead see how 15 psi boost would be. It was fine, no knock. 20psi, no knock. 23 psi, no knock! 24 psi, got a little knock, no transitional knock though, but egt's were @ 1625. The last blast I did I turned the alchy system on, and turned the pump speed as low as possible. 24 psi, no knock. That was enough for tonight. Tomorrow I'll change the oil, and friday (took the day off work) I'll start tuning. first thing I'll do is change the activation point to 5 psi. I'm already thinking of going to much smaller alchy jets, so I can keep the pump speed up, and atomize well. I suspect that alchy injection is still needed both as insurance, and as a way to keep the temps down, and increase boost even more. A word of advice to anyone doing this, watch your egt's! The 1625 egt reading was at 85mph, I'm sure a few more seconds into the throttle, and bad things would have started happening... Another thing, the propane is taking the place of oxygen in the exhaust, and the 0-2's were all over the place. I read anything from .810 to .430! The .430 was on the 'hot egt's run', so at least it is tracking somewhat. So far things are looking very good.
