Hello Craig,

Do you have the GAMI injectors or was your engine set up in a special = way?

I thought that LOP operations are approved up to 28 inHG. I would = like to run mine with 32 inHg but I am afraid to damage = something.

Here is what I see so far:

Climb – full power – full rich (this gives me the coolest = temps) – 160…170 IAS – CHT 380 – 390 – = results in 1600 ft/min (beginning) 800 ft/min = (end)

Level off at FL22, FL23 – full power – full rich – = TAS 292…297 (on the bezel – I know this reads high) – = #3+4 CHT 380 - 390

After this LOP at FL22, FL23 at 28 inHG, 16.1 gph – TAS = 270…275 (on the bezel) – #1 CHT 360…375 =

Like I said I would like to run it at 32 inHg LOP but I am afraid I = damage something.

Ralf

Going to Oshkosh:

25,000 ft

ISA +36 degF

2500 RPM

32 inHg

16.9 gph LOP

276 kts TAS (Chelton)

374 degF, #2 CHT

5.1 psi cabin pressure

In my limited IV-P time, I see about 3 kts per 1000 ft altitude = increase. CHT’s at 18,000 ft are very low (345 degF) and = CHT’s at 25,000 ft are as above when LOP. I don’t fly = ROP except for climb. OAT significantly affects fuel flow and = therefore speed when LOP. The IV-P is a fantastic traveling = machine.

Hello guys

So today I was happy flying with my 4p going from Daytona to Raleigh = and was wondering what cruise numbers you are = using.

For example I was cruising with a MAP of 29, FF=3D16.7, 2500rpm and did = 234kts at 17500ft.

So what are your numbers? LOP? ROP? Ron Stevens
