Boost #'s... what does you gauges show?
Boost gauge is 0 to 25 with at what I would guess are: 0, 6.25, 12.5, 18.75 and 25 lbs. Those red number are a guess but seems right.
Mine is right below the 18.75 line. Owners manual supplement says it's SAE HP numbers are at 19.5lbs and up to 21lbs can be achieved depending on atmosphere conditions and gas.
Curious what others are seeing??????
