Mine is #2, which seems odd to me. That cylinder seems like it should get the most air flow since it’s sitting right in front of the air inlet on the cowl. #1 is the second hottest. The rest of the cylinders are in line with your temps.

That’s about on par with what I’ve heard from other 46 owners.

I have read on other forums that there is a known cooking issue with the Togas. Under your cowl are some cooking baffles. These have a tendency to crush / compact/ or otherwise get out of shape. When corrected owners have said they see their cooking return to expected levels.

Which cylinder is your hottest? Mine is usually #4.

Joe, I wish I still had my Mirage. For the money, there’s nothing that will do what a Mirage can do. It’s fast, efficient, and pressurized! I had a late 80s one with a great useful load. There is a ton of bad press about the engine and other incidents that are largely blown out of proportion. If you want to the real story, talk to an owner or better yet join MMOPA. The downside is the maintenance. Parts are EXPENSIVE, and it’s a 10K annual if nothing is broken (which never happens). I sold mine due to lack of good maintenance shop options where I live. It’s hard to fly hours away and have to find a ride back anytime something needs to be fixed. It’s definitely not an airplane to let just any A&P work on.

Back to the topic at hand. Your temps and fuel flow are what I expected to see, but aren’t even close to mine. I flew at 11K yesterday and I couldn’t keep #2 under 410 unless I was over 23g/hr. I was using 29/2400 and getting just over 170KTAS. I’m wondering if this a cowling issue on my airframe.

Hey Steve. I’m a new owner as well, but mine is a 1981 Turbo SP with the Intercooler (pretty close setup to the II TC model). I run a similar power setting to you, and that gets me about 74% HP in cruise. I’m seeing CHTs around 350 and EGTs around 1450. TAS is right at 162 and fuel flow right at 19.5-20.5 (depending on altitude) with the mixture down to the stop. Bump it up to 31in and fuel flow at 22 (80% HP) and I’m getting 170 TAS and temps are marginally higher (CHT 380ish and EGT 1500ish).

Out of curiosity, why did you move from the Mirage to the Toga? I’ve been considering whether I shouldn’t have gone to the Mirage.

I’m the proud new owner of a 2003 Saratoga II TC. I’ve put about 30 hours on it now and wanted a consensus from other owners. I just transitioned from a PA-46 Mirage and I’m disappointed by the fuel burn and CHTs I’m seeing. The Mirage cruised at 21.5 g/hr and the CHTs were always in the mid to low 300s, especially this time of year when it’s cold. So far I can’t get anything even reasonably close to book values for cruise fuel burn while keeping the CHTs in check. #2 cylinder is always over 400 degrees unless the fuel flow is north of 23 gal/hour, and #1 is not far behind. The rest of the cylinders are where I would expect them. I’m running at 29 in and 2400 rpm in cruise. Are other TC owners seeing the same issue? Drives me nuts buring this much fuel to go as slow as I am.

Thanks in advance for the input!
