Dave, any news on the engine test in Idaho?

Yes it's true and very good news!! The engine performed as expected and was just beautiful to see, watch and hear. It's late and I'm tired, just got back. I'll post more this weekend.
Dave

Well, here are some of the pics from the engine test!

This is the Anderson Aeromotive Shop in Grangeville Idaho.


This is the test wagon with the new engine in tow.


The engine is mounted on the test stand with a Sky Raider mount.



Isn't it beautiful!! That prop is off a Howard 500. It makes alot of wind!!


This is Dan on startup! I got to run it too!!



This is the instrument panel where we both monitored the temps, pressures, flow rates and RPM.



Makin' noise!!


We checked the oil screen about every hour of running and it just kept getting cleaner and cleaner. After running 15 hours, they did a compression check.


This is Ray!


Dan's pulling the prop through for Ray to bring the pistons up to TDC for the compression tests.


One of the really cool things up here is that most all the tooling and equipment is old but made for this stuff and working. This is Jerry, testing the coils and mags.


Finally a pair of Rays horses, Pratt and Whitney!!


This is a portion of the parts for the next engine that have been cleaned, inspected and preped for assembly for Dan.

Fantastic

Congratulation for all the people involved...

Thanks for the pics.

A huge thanks. Very nice photos. Just good stuff.

Some questions.
15 hours, was that all consecutive? Same day.
Do they run it in that tunnel, and must be for cooling?
How many gallons of fuel for the test?
Are they on the airport?
It looks like Seattle weather wet.
So Dan does all the assembly or is it a team effort?
I bet it was loud with those short stacks, did it run at night? if so wish you would have got some pic's.
Hope you guys have them do the rest, well cept for the one at Abbot.
I bet they even have a real warranty.

My God man! Don't you sleep? So many questions, so little time!
15 hours was over a 4 day period. Yes it ran in the tunnel and the fuel consumption is based on what power setting we were running at. We ran at 1000 rpm,1200,1400,1600,1800,2000, 2400 and finally at 2850 with 51 inches to prove the blower. Fuel flow ran between 200 pph @ 1200rpm to 1800 pph @ 2850! Not on an Airport. Dan does most all the 3350 assy.

Dave

Congrats on the engine run. Hope the rest go as well

On the set of engines done by Garys favorite place, did they do that extensive of a test? We are guessing not, I bet they only ran a few hours if that. Well at least FiFi will have some quality engines now.

PPH ?? Pints Per Hour?

25 and 225 gallons per hour then.

Most shops don't run engines that long. Typically, it's four hours or so, give or take a little. Precision ran the old junk engine 8 hours, although I'd requested 15+. I don't know what Dave has requested, but the 15 hours that was run on the new engine is a good start.

Gary

Would the different propeller being used, change resonate points? You know restricted rpm areas? And what about the props used on FiFi, being compatable with the different dash engines as far as any restricted rpm region? Also out of curiosity was the crankshaft reground?

Dave, Very informative post and photos, After the engines are insalled on Fifi will you be using BMEP gauges and an engine analizer to mointer the health of those engines? Thanks Carl

Do Fi Fi's bombays open? In flight?
