At start up it is just a 12 cylinder engine, but when the revs are up it becomes a Merlin. Beautifully maintained, runs like a dream, well done to you all, you have something very special there. All you need now is the tinwork to go round it, then get it up in the sky where it belongs......Tally Ho.
It's a balance of how much fuel primer is used. Have a look at this slow motion; just two blades of rotation before it fires! th-cam.com/video/bhOjcU2sPpk/w-d-xo.html
I wonder what RPM and throttle percentage was the engine running at 5:19. I'd like to know because I play a WWII air and ground combat game called War Thunder, and I am at least sure that their sound modeling of the Rolls-Royce and Packard Merlin engines are unrealistic. Thus, I'd like to know so I can make a sure comparison of ingame and the real engine sound.
2,500 rpm engine speed, or 1050 rpm propeller speed (42% reduction gearing). Throttle is barely open; the boost delivery is approx -3 psi at that speed giving about 500 hp (of the 1,620 hp available). As a guide, full power at sea level the throttle is open about 40 percent. The automatic boost control limits the actual throttle opening according to the power mapping of the boost performance against altitude, and works independently of the pilot's throttle position. As regards simulated Merlin sounds, I suspect some software have sounds at idle, mid and full, and mixes between them. I have been asked to provide sound for simulations, which I am happy to arrange. RR and Packard engines sound the same, although they differ depending on exhaust stubs they use. Hope this helps.
Pure. Joy.
Thank you ❤

Hello Oliver; thanks for your comment. There are lots of engines now in the HAE group and shown on our Facebook page. Thanks for watching.
That was 7minutes of pure joy to watch
Thank you Chris. You are welcome to follow the group on Facebook, where there are other engine projects ongoing.

Beautiful.
Nice sound- 2 thumbs up!
That keep you cool in the summer giant back yard fan👅
That baby chugs 2.5 gals of fuel per minute at full throttle
Came here after jays garage nov 7
Two thumbs up
Welcome to our channel. Jay has a Packard V1650-1 on a trailer, that was originally built by a friend of mine.
Pop know his stuff. Watching this was like sippin cognac. Grab me my goggles and clear the runway damnit !
Excellent video much appreciated
My pants got tighter listening to that
That didn’t take long to start

Historic Aero Engines that’s nice!
Historic Aero Engines it’s funny how this engine creates more power and toque than the w16
This version of Merlin develops 6250 ft/lbs of torque at the propeller :-)
Historic Aero Engines does it matter on propellers ? ;)
