Thought I'd start this thread for people to contribute their experiences in creating a successful auto engine conversion. Any engine brand.
I hope that it is the wrong way up!Almost finished installing an LS2 in my 3/4 replica 109 but "successful" remains to be seen.
Would love to here more . . .
Very interested to see that! Please feel free to share some information.Almost finished installing an LS2 in my 3/4 replica 109 but "successful" remains to be seen.
However unlikely, that would be so good..!I hope that it is the wrong way up!
Good idea. However, a two bladed prop turning 1000 RPM, equates to about 33 blade passes every second. Being a mechanical device, I doubt that an altimeter would do anything but average the pressure at each location. To detect pulses, a fast pressure transducer may be required for the job. Detecting reverse flow may require a tool that can sense quick direction changes … I have no idea what that would be.Should be a very easy experiment: plastic pitot tube, altimeter, slide it fore and aft behind a turning prop and see where highest pressure is found
Tracy Crook's original cooling setup for his carburetted Mazda 13B had radiators under the cowl of his RV-4, and I don't recall him having effectiveness issues after he solved a bit of trouble with the turbulence around the inlet lip. He was keeping up with O-320s. That's not to say his installation was as efficient as it could be, but it did seem to work.My original post was aimed at finding aircraft with water radiators mounted near the prop that are both effective and efficient. With effective cooling the plane should be able to taxi, run up and fly without cooling problems. Efficient cooling has taxi temps, climb rates and air speeds that match or better the same model plane as yours but has a Lyc or Cont engine.
Sorry, couldn't do the inversion. Not smart enough for that.Very interested to see that! Please feel free to share some information.

Got any pictures or info of yours or Russell's setup?Russell's ventral radiator success prompted me to finally get off my butt and ditch my "collection" of rads scattered all over my RV and replace them with a single ventral rad in a proper duct 6 years ago. Cooling was improved and drag and weight reduced at the same time. I was able to measure net thrust under some conditions.
Look at the Canadian Northstar cooling package. It has the radiator under the spinner up front.
