Byron, Indeed I heard that the LASAR ignition raises the CHT by 40 degrees... and that I should actually install such a device you mentioned in your email...but if I were to do so, the benefits of the ignition disappear. Now, the question comes up is it worth keeping the LASAR or should I revert to the normal magnetos...? Oscar

Thank you for this great post. I have am overhauled engine on my M20C with a LASAR ignition, about 20 hours total time, and I am experiencing very similar temperatures in my engine... Last Friday I landed inmediately when the CHT reached 500... It was scary. I took off the cowling and reviewed the baffles and the dog house. I have not flown since then, but I hope to do it on Monday to check everything out. Oscar Quote: pmccand My ramblings and notes about high engine temperatures... I have also had FRUSTRATINGLY high temperatures for which I have requested assistance on this and other web sites after a recent o'haul on my O360. In my case, I tore the engine down a SECOND time in less than 50 hours, after I found two rebuilt cylinders delaminating nickle from the walls! I suspect very high temperatures were partly to blame. I couldn't get temperatures down after 25-30 hours. I'd start up and make the taxi and pre-flight as short as I possibly can, rolling as soon as CHT's reach 250 deg F. Upon climb and just after retracting the gear, I find the temperatures at or near 450-480 degrees, and on a really hot day I push red line. Climb out is at 120 + MPH with full power, full rich and cowl flaps wide open. I drop the nose to cool the engine as much as possible until I get 420 degrees or less. At this setting, I can climb only at about 800 feet/min with a light load. Gauges and probes are checked for accuracy. Carb modded with the ancient service bulletin for the early 61 engines which richened the mixture, and timing re-rechecked. What's really scary about this is the temperature would SCREAM above 500 degrees if I came in for a landing with a hot engine and tried to do a go-around. I made a call to Don Maxwell and asked him what his temp experiences were with the M20B O360 engine. To my surprise, (and without telling him what temperatures I was getting) he said that #3 is ALWAYS the hottest, 390-420 degrees in cruise is "typical" and upper 400's are not uncommon on climb out. "That's the way they are", he said. So, based on his report of normal behavior, I decided to fly it as-is. In my quest to further lower the temperature, I did the unthinkable...I installed a LASAR cowl enclosure mod, just to see what would happen...and what do you know...CHT DROPPED on climb and cruise by 10-15 degrees with a SMALLER opening! At least, it didn't hurt to install the mod which suprised the heck out of me. The biggest improvent was a modification to my flying procedure... Nose down and climb slower. Contrary to what most people are doing (as they descend with full power), I make SURE my engine is cooled and leaned properly when descending; just in case I need to make a go-around and want full power. I shoot for 250-300 degrees just before landing with leaner mixture setting to prevent lead fouling. Just my unsolicited ramblings, but perhaps my notes help somewhere. Phil Mc Ca nD.Less

Well after about three months of hard work my panel upgrade is finished... I also redid the interior.... Although I have to say I am a little bit concerned about information overload. Any recommendations... Oscar

Great

Happy to contribute.

Thank you for your tips...

Yes, what happened?

I read the article... very nice bikes, although a little bit on the expensive side...

She just took a pinch hitter course... so who knows may be she will be ready to fly again. Any suggestions...

Yes, I had her there...but then we had a complicated trip with icing etc in the Northeast and she got scared...since then I have not been able to convince her.

Really nice! I have been trying to convince my wife to use our mooney to travel... but until now to no avail.. she believes that you can only travel savely in jets...

have a great flight back!

I would be interested in purchasing three at that price.

Really nice!

I would be interested... with the caveats expressed by others...

Lucky you..losing your grandfather in law's airplane key sounds like big trouble

My NEXRAD and my wx900 worked well together while I was flying int he northeast. However now I feel that my wx900 is not enough and I am installing a wx500 with longer range and better software.

Really nice...congratulations

Congratulations! Wy to go

I have been using a LASAR ignition for several yes. It works great. In the past I had difficulties starting the engine. After installing the LASAR it starts much easier. I also like the fact that I now have the LASAR plus two magnetos as a backup. Does it make a difference in terms if mpg, I really don't know...

Many "maybes" but the reallity is that many times you don't get a second chance if you are not careful and fly by the numbers. So let us be careful out there.

I have many times too. However, now that I am flying more and more in Central America I have to trust my WX 500 and my eyes. So if I can not see it... I don't fly through it.

Wow... really scary... Mooney speeds have to be managed VERY CAREFULLY

I know, I tried to find the discussion but to no avail. However, I went ahead and replaced the nav and strobe lights with aeroleds. They look great and work just fine. For the landing light I have the Lo presti Boom Beam installed since 2004. The light is really wonderful. However, I would like to have some wingtip taxi LED lights installed too. Well, may be later.
