I shouldn't encourage this, but here you go.
What are those anyway, Westbends?

I'm not the original poster, but find this really intriguing.

In the second video I watched, they seemed to be really preoccupied with the temps, like maybe they already knew that the air cooling setup was deficient. But it is still interesting to me, because I think I recall having seen a video or post about a scale version of the MoPar L-Head 6 someplace. (Probably on the P15-D25 forum. That is the flat-head in-line 6 they used from '37 to '59, and continued to manufacture for industrial use afterwards, maybe until the early 70's or so.) Anyway, I love the sound of the old flat-head sixes.

Fail from me!

Oh Dave..........where do you come up with this stuff????

He mentions in the videos that if you understand the basics of engines, you could figure the Crankshaft out...

I applaud him for not giving everything away.... Best way to stay original.

That is an incredibly cool build and it looks like a factory job, like an old Henderson 4 Cylinder

Cut it with and Axe, Beat it to Fit, Paint it to Match

Do it!

Look at the Multi-Engine Chain Drive Hill Climb Specials in England...

Those were Cyclecars...

Your are building a Cyclekart, smaller scale, smaller engines...

I agree with Rhys, This is the Custom Forum... Go For It

I would have to agree. The proof is there, that it CAN be done, it's up to you to figure precisely how. What's the fun in having the whole recipe in front of you?

Hello, there!
Of course that it is possible - that was tried and often finished with success from the early period of motorisation (automobiles or motorcycles, but boats and aeroplanes too). Anyway, all engines from the early days of motorisation - started as single-cylinder and later got brothers and sisters to become multi-cylinders (except Daimler - it had 2 cylinders from start?).

Combination of a few smaller engines to get a bigger one - must be more complicated and often more expensive way than to go and buy one big, well-proven and practical. However, sometimes it couldn't be found what we really need (better-said want), so many amateurs and professionals made and still make such combinations.

Sometimes, they are simply connected small engines (as Rev. Bow said - English specials) and sometimes are made bigger engines of the main components of smaller: a pair or more of a single cylinder, or two-cylinder or four-cylinder, even six, eight and twelve. Voisin made one extremely long engine connecting two straight-8 engines, but just as a prototype... Therefore, if you want to do it, have experience and knowledge, workshop and money - why not?

For my taste, technically and aesthetically it would look better if you constructed as a monobloc, even with separately visible cylinders - than as four engine connected in some way. Meaning: fixed blocks of small four ( to look as one big block), all of them keeping their own crankshaft, camshaft and valve mechanism, but with engines connected by chain/sprocket combination, or pulley/toothed belt combination or by gears - to simple straight propeller shaft "hidden" beside or under new engine and covered by formed plates to look as a part of engine block (crankshaft). Constructing own crankshaft could be a problem? As I know, the smallest four-cylinder engine was from FIAT 500 Topolino - 500cc, but using its crankshaft could bring more problems than benefits?

The cylinders could stay "naked", as in many old engines from the beginning of motorisation, no matter if water-cooled or air-cooled, or to be covered with some plates that would improve cooling and add to esthetic? (as on shown video).






Of course, all written is mentioned before in this topic, more-or-less in the same way, but I would like to expose my old ideas, more dreams than plans. I will follow your project with great interest, joy and amusement! Would your finished racer be a Cyclekart? Probably not, but you shall have great time designing, constructing and driving it. maybe it could be accepted as a pace car for official races?

Regards,
Zoran

A few years ago, I was going to motorize a bicycle and I considered a 2 stroke generator powering an AC electric motor. Lots of torque, speed and with a flip of a switch you could go 40 mph in reverse.

Ummm... this is probably the best idea ever.

I think this engine(s?) will sound AWESOME! I think a vee or opposed type arrangement would be great, and would look cool in a “kart”.

I hope you make this work, because I am in awe.

Peace,
Robert

Well that's impressive but I like straight sixers



And what could be better than a six...how about 8!

What if you did not time the engines but used a clutch/ratchet on each similar to a 10 speed bicycle.
Remember hearing the the rear wheel click as you coasted.
As the fastest running motor loaded up and slowed down the other engines would catch up and
engage there clutch/ratchet and pull together.
