Re: Question the church !
I will try to address all the comments, in a row, here.
1 In my mind 12.9 or 12.1 to 12.5 are the same. Everything is moving around and any reading is a function of the instrument used to measure it and the point in time that you look at it. They are so close to ideal that they would defy improvement without an inordinate amount of work. ie not cost effective to me.
1A Do not know about boost codes, I got it off the car before I got that condition, May find out soon enough as I wanna run stacked with the present boost modified fuel pressure to get a chart recording.
2 After I get reliable operation a dyno is next, yes. The Egt I believe is another way to see the A/F and I have both a gauge and zeitronic d/l now, so trying to record and evaluate egt or 6 egts in not in my budget at this point.
3 My boost readings come with an elevation of about 500', baro pressure typically normal I believe 29.92 "Hg.
4 The stacked pulleys run up the s/c about 3 to 1 versis the 2.56 to 1 of a 185 set-up. Heating is a function of the efficiency ( fixed in our s/c ) and the adiabatic heating, of compression.
More boost is more heat, but I dont feel that my I/C is a limiting factor yet as the air temp especially now is very moderate, below 120F to date. My H/E is 3x the stock size , and is measured to flow 2x the water GPM of the LET unit I had. THe H/E is also positioned directly in front of the Main engine fan/radiator shroud. With my 180 degree thermostat, it keeps the temp gauge below 1/2 scale in the summer while driving.
