Thumbs up The Mountain

Well Folks I've done it.
I have climbed the mountain and made it back again.
I didn't meet Moses but I did visit a very earnest young gentleman who was keen to show off his latest offering to the aviation world.

Yep, I stood there and watched the third start up of the new Autoflight 140N engine.
She fired almost as soon as the starter engaged and ran sweet and smooth.
I am really looking forward to seeing this engine in greater numbers, doing what the Sub 4 engine did/does only better.
You heard it here first.

Cheers,
Gordon Gibson.

Is this a new engine from the SoobMeister?

Sure is Scott.
Double overhead cam (special cam grind), custom cylinder heads with vastly improved porting like the Sub4, dual electronic ignition coupled to a LINK engine management computer, EFI, beautiful light & quiet exhaust, overall low profile which will be excellent for a tractor config on any aircraft, integrated engine mount system, custom pre-rotator if used in a pusher gyro, very attractive overall weight when matched to an Autoflight reduction gearbox....and there are probably other features I have missed out.

To be fair it should be pointed out I have ben a friend of the Soobmeister for years and I only live 80 miles away.
And I will own one of these engines before very long.
Nothing like a bit of bias!

Cheers,
Gordon Gibson

Production engine will have 50mm lower inlet manifold and slightly smaller. May also lose the distributor off the end of the cam ( for fixed wing applications).

Neil, I LIKE IT !

I have 2 spare EA82 engines & one in the car that I drive. The 2 spares are both turbo engines with MPFI. The one that I drive is a SPFI.

What FI system are you using on it ?

Which engine would be better for your heads ?

Is this lighter than an EA81/Sub4 ?

Do you feel the belt cover is a necessity ?

What type of prerotator ?

Thanks

The only part of the EA82 I use is the short block ( 32kg ), all else is in the bin. I use Link EFI ( local system ) . Projected weight of this engine is 85kg ( dry ) but this development engine is around 92kg. Lots of small changes to be made yet. Yes I would think a cover is nessasary as the cam drive is quite important, will be carbon. My prerotator system is a direct drive unit using a cone clutch in oil with an angle drive, small CV joint and sliding spline. It is not fitted in these pictures.

Thanks Neil. How does that compare to the Sub4? I don't quite understand the "at the prop flange" bit.

Well, most engine manufactures will refer to their HP at the crankshaft. There is a loss in the reduction drive ( friction ) so the power at the prop flange will be less that loss ( ? ) in the gearbox. Power at the prop flange is whats most useful. this Autoflight engine could be delivering 152 at the crank, but who cares because we want to know whats happening at the part that actually twists the prop!
SUB4 was 118 with carbs and 125 ( on a cold day at sea level ) with EFI.
SUB4 ended up about 95 / 96 kg's in the end.
