Mini Harley Davidson Panhead Engine (Sounds Like the Real Thing)

I set up and test run this miniature Harley-Davidson panhead engine, I handmade a custom set of tuned exhaust headers, I design them a certain way to see if I could get that very well known Harley-Davidson engine sound.. and to my surprise it came out absolutely amazing.
this thing sounds so similar to a real engine just scaled down.
this is a nearly exact scale replica of a Harley Davidson panhead engine it is very very impressive.

well when you think of it, Harleys use engines smaller than a Honda civic. for engines like this, the tune, intake, cam, crank, and configuration matter more than the actual size, while an American v8 makes its sound from displacement and overlapping exhaust in large pipes. its its truly a work of art, to make good sounding engines

it sounds faked. Listen to it the 2nd time he let it idle. It doesnt sound the same.

[@WarpedPerception]

@@FranBunnyFFXII that's because the first time it was running on gas and in the middle of the video I had to swap it over to nitromethane with glow plugs. But I cut the clips together because I needed to but they do sound a little bit different running on gas and nitro methane. Good ears though.

Great, but needs bigger bore exhaust pipes to really let that V twin noise out. I can't see how a quick blip of the throttle broke the crank, more likely to be a manufacturing issue. Another seriously great episode, man I love this!

[@WarpedPerception]

You're right that was one of the issues I had, I need to source some thinner wall larger OD material, but the issue is the way it threads into the head. I'm sure I can do it though and I'm positive it would sound much deeper

As for the crank, yes your right but I didn't want to say that.

The "back" cylinder fires first then the "front" fires. So both fire on the same cycle. Makes you wonder how it keeps running without power on each stroke but it does fine:)

[@BADHIGEEN]

flywheel

[@rubiconnn]

Single cylinder 4 stroke engines exist...

[@alberteinstein3078]

?

[@rustbeltflow3523]

They don't fire on the same "cycle." When the rear cylinder is at TDC on the compression stroke (firing) the front cylinder is approaching TDC on the exhaust stroke . Due to the 45 degree bank angle and 720 degrees making two complete revolutions that leaves 315 degrees between one firing event and 405 to the next. That's what gives the "potato potato" sound

[@rosiehawtrey]

On each power stroke the engine puts power into the inertia flywheel. The flywheel is heavy and maintains its movement pulling the engine into next firing stroke - this engine would never run without it because the of the time between firings. A 6 cylinder modern engine like my vitesse 2.0 can have a small flywheel because of the number of firings is enough alone to keep the engine spinning. The big old agricultural engines do have a flywheel with multiple cylinders not because of firing order but because of low speed, a Fairbanks-Morse 32E engine might idle at 75-100rpm, the Vitesse/Herald engine idles at 750.

Just a little FYI for those out there that are fans of miniature engines. The heating and cooling properties are not a linear relationship. It’s actually pretty complex set of engineering calculations. I only say this so you understand an air cooled engine like this could have massive heat dissipation issues. It could burn up in seconds. The oil cooling and lubrication has the same problem, it doesn’t scale in a linear fashion either. Even on something that started as a reliable large engine design may only last you a few hours in a scaled version.

That's why moped engines are impossible. They don't exist. Mopeds ride on pure magic. Everybody needs at least 10 inch diameter pistons. Not because of the valve size and the amount of fuel getting burned, no, because of the non-linear relations involved. Large is far easier. Nano scale is extremely complicated. There's a Nano Harley, but nobody sees it. You need a microscope and the thing gets lost in no time. And the cooling issues, off Corse. How complicated this world is. Pfew!

Very interesting comment

[@michaeljohnson9969]

That and you can’t shrink the oil and fuel molecules to scale. Heck, even the air molecules , and flame front would be a problem.

Need some good old non-steady state thermodynamic dimensionless analysis .... a classic Chemical Engineering design 'tool'.

Thanks.

What a sound! It is certainly a Harley and sounds great. Nice job of putting this video together.

My old '64 Panhead SN was FLH4646. Traded it away 50 years ago.

[@manuelestevez91]

this has to be one of the coolest things I've ever seen lol

[@CharlesManch]

Damn.....sounds way better than the real thing, i.m.o. Nicely done!!!

[@WarpedPerception]

Thanks!

[@hoopoo3721]

Even leaks oil like a real Harley :)

[@BNatoAk]

I hear it run, now I'm imagining the coolest r/c Harley Panhead bike!

[@RC-Heli835]

That sounds better than i expected!

[@haha_you_dead]

That Little Engine Looks So Good 😊 Sounds Great As Well But The Starting Method Doesn't Look Sustainable 😂🤣🤗

Not sure what inner diameter pipe you used for your exhaust but that dimension is critical if you're trying to duplicate the flow, scavenging & sound behavior of the full size system. Great projects & videos. It's time I hit the subscribe button.
