Other shops have different criteria, but this works pretty darn well. After the engine is pre-oiled and gage pressure of minimum requirements (45 PSI) is met, the engine is started and operated at 1000-1200 rpm and 13-16 in MP for 5 minutes or until 100 degrees Oil temp. Then, 1500 rpm and 15 inches for 5 minutes, quick mag check, 1700/16-17 until 140 oil temp is achieved, then 2000 rpm and 19-20 inches and wait for vernathern to close (usually 189 F), perform a mag check then 65-75% which is usually 24/24 maintain 200 F oil temps, and 390-400 F HOTTEST CHT. Lean to .53-.54 BSFC or 1400 F EGT for 30-45 minutes, oil pressure is set at this time. This is when you start seeing your MP rise, thus rings are STARTING to seat. The CHT's are cooled down and a full power run is done for 3-5 minutes leaned to best power. This ensures the engine makes rated power. The engine is slowly cooled down and RPM reduced to 2000 and another mag check is done. The power is then reduced to 1000-1200 rpm and 13-15 MP, then slowed to 650-750 long enough to show hot oil pressure at idle. From this point the engine is properly shut down and a hot differential compression check is accomplished. If all systems are go, the engine is preserved and ready for post dyno inspection. At this time, the computer is downloading the test data that is delivered with the engine. We get a copy, and you get a copy. This in no way means the rings are seated. On nitrided cylinders, it usually requires approximately 10 hours for oil consumption to stabilize. When oil consumption stabilizes, the rings are seated the best they are going to. I don't think there are too many folks who want to pay the additional costs of 8-10 more hours of dyno time to get the rings seated. The best thing for you to do is once the engine is installed,(don't forget to add oil)! Start and run the engine on the ground to let the CHT's get up a LITTLE bit. The cylinders are still susceptible to glazing if the temps get to high. Shut the engine down, check for installation leaks, cowl it up and go fly for a minimum 1 hour at 24-25 Square. The whole key is consistent RPM/MP.

Our dynamometer is a water break system meaning we can simulate a prop load. The engine sits on a test bed and is fully enclosed, except for where our test lines(fuel metering, oil pressure, etc) are fed to the engine, and the exhaust is exited. Therefore we have a cooling tower to force air into and over the engine and cylinders to keep the engine in operating temps while we test the engine. We also have the capability of testing practically every perimeter of the engine, so technically, yes, there are a lot of special test equipment used during testing. When ground running an engine, there is not a way I know of to keep the cylinder head temps under control because of the lack of airflow to the engine. The CHT's would hit orbit before the oil temp could get to 189. Even aircraft taxiing tests can be detrimental to the engine if done for extended periods. I would not advise copying the test in the airframe. If you guys are interested, we would be more than happy to run your engines on the dyno. We run other engine shops engines here as well as a few owner assembled engines. We do have to cover labor and fuel costs, but it's well worth the costs involved. It's under a grand for an hours run. Good Insurance IMO. I know, maybe you guys are thinking 'here comes the sales pitch'. That's not it at all. But The first breath of a babies life is it's most important, and at the cost of engines these days, it really IS important to know there are no issues with the engine when it's installed in your plane, isn't it? You even get to sit side by side with the test operator and see your engine running. If you've never witnessed a dyno run, you will be intrigued, for sure. On a side note, if anyone is interested in an owner assist engine build seminar in Sept. (24) send me your address off line, and I'll get you a registration form mailed. We will be building an O-320 with Matt Brandes of K.C. for his RV-9 project. It will be a 1 day build that will explain the do's and don'ts of building your own engine and some of the pitfalls as well. The seminar will be at Lee's Summit MO. EAA chapter 91 hanger. All are welcome but space is limited so if you're interested, I need to get your form to you pretty fast. Email me at bpa@bpaengines.com and I'll snail mail you a form.

Big fans running for cooling? These are nice simple steps below and I have a first run coming this month on my plane and plan to print this and have it in the cockpit with me during the first runs. I wondered if I could keep cht's down enough on the ground to get the oil temp to 189 while getting these run times.

Other shops have different criteria, but this works pretty darn well. After the engine is pre-oiled and gage pressure of minimum requirements (45 PSI) is met, the engine is started and operated at 1000-1200 rpm and 13-16 in MP for 5 minutes or until 100 degrees Oil temp. Then, 1500 rpm and 15 inches for 5 minutes, quick mag check, 1700/16-17 until 140 oil temp is achieved, then 2000 rpm and 19-20 inches and wait for vernathern to close (usually 189 F), perform a mag check then 65-75% which is usually 24/24 maintain 200 F oil temps, and 390-400 F HOTTEST CHT. Lean to .53-.54 BSFC or 1400 F EGT for 30-45 minutes, oil pressure is set at this time. This is when you start seeing your MP rise, thus rings are STARTING to seat. The CHT's are cooled down and a full power run is done for 3-5 minutes leaned to best power. This ensures the engine makes rated power. The engine is slowly cooled down and RPM reduced to 2000 and another mag check is done. The power is then reduced to 1000-1200 rpm and 13-15 MP, then slowed to 650-750 long enough to show hot oil pressure at idle. From this point the engine is properly shut down and a hot differential compression check is accomplished. If all systems are go, the engine is preserved and ready for post dyno inspection. At this time, the computer is downloading the test data that is delivered with the engine. We get a copy, and you get a copy. This in no way means the rings are seated. On nitrided cylinders, it usually requires approximately 10 hours for oil consumption to stabilize. When oil consumption stabilizes, the rings are seated the best they are going to. I don't think there are too many folks who want to pay the additional costs of 8-10 more hours of dyno time to get the rings seated. The best thing for you to do is once the engine is installed,(don't forget to add oil)! Start and run the engine on the ground to let the CHT's get up a LITTLE bit. The cylinders are still susceptible to glazing if the temps get to high. Shut the engine down, check for installation leaks, cowl it up and go fly for a minimum 1 hour at 24-25 Square. The whole key is consistent RPM/MP.

It is a Chevy V-6 4.3 liter engine with it's stock electronic ignition. He lost all electrical power during cruise, thereby losing engine power. He put it into a wheat field with NO damage. Last I talked to him he was planning on pulling the plane over to the farmer's brn, figuring out what broke, fix it and flying it out of the field. The sad part is he had bought it just one hour before up in Walla Walla.

The aircraft had been purchased 2 weeks ago from a friend of mine (not the builder) and the new owner was receiving training due to his lack of confidence in his abilities with his new aircraft. In this accident, I loss a good friend of mine, the passenger, Robert Riendeau, a true gentleman and RV builder. Robert, was in the final preparation toward a flight next year in his RV-4. In the mean time, he was flying a KR-1, which he bought a few years ago and totally refurbished. The RV-6 (Mazda Powered) had been very well maintained and had been worked on extensively last winter. From initial reports, the aircraft appeared to have suffered an engine failure and crashed almost strait in the river (most likely stalled). We should know a little more in the next few days.

I agree that Lycomings seem to quit frequently also, but there are thousands and thousand flying while there are reality few auto powered aircraft. Condolences to the family and friends.

Heating from air friction doesn't become significant until you're well over 200mph, as I recall. It might be detectable in a very energetic RV-8. Simplest is to just put the probe behind some obstruction so it doesn't get the direct blast. My RV-6A has a Lift Reserve Indicator probe which is a pretty stout piece of aluminum sticking down from the underside of the wing. I mounted the OAT probe just aft of that. At least it won't contribute much drag there (I assume). sportav8r@aol.com wrote: >--> RV-List message posted by: sportav8r@aol.com > > I think I'm following you, here, but is that warming effect from friction, a-la spaceship re-entry fireball stuff, or compression of the air, as in ideal gas laws (Boyle's?).
