My little brother got a LEGO F1 ferrari car from a garrage sale yesterday and made a LEGO V-12 engine that goes in the car and that got me thinking... Would this type of thing be possible if one used 12 cox .049 cylinder and piston sets with a custom made crankcase, crankshaft and some way for fuel injection
Could you guys help me here with this one, i also saw a inline cox 4 cylinder engine on youtube in this video link... https://www.youtube.com/watch?v=HG8F-wQYeK0
i did the math and 12 .049s equal a displacement of 0.588 or 9.828cc
thanks

Yes it could be done. Easily? No but, it's possible. My advice is to stay in school and get an engineering degree and dabble in machine work on the side!

It would cost quite a bit of money Mitch unless you knew an accomplished machinist that is willing to work for free or has an interest.

It need not be fuel injected as a carb would work fine as long as you can create a vacuum.

Keep in mind it would probably only be a showpiece as it would weigh a ton and the power output wouldn't be adequate for a plane big enough to carry it.

+1 to what Ron said. The machining equipment required is not cheap.

If it was built light enough, it would make a nice boat engine.

Well I've always had a 'how can I blow it up' mentality....
My last big stroker was an RD500lc (RZ for you Canadians) which those of a 'hairyarsed' biker slant will
remember was the last Hurrah of Jap 2 strokes and a very clever V4 formation.
I seem to remember it red lining at about 11000 and after much butchery (sorry tuning) we got it to about
13.5 before it went BANG
This was with a very efficient water cooling system and the financial might of Yamaha behind it.
Point I would make is Yes it is possible but an aircooled V12 spinning at 15000 rpm isn't going
to run very long.

Hmmm,

Come to think of it, if you welded 12 babe bee cranks together inline with smartly spaced main bearing journals and crankpins placed at 30 degree offsets...... lol!

Who knows I am sure it's possible where's Jason?

Here's hoping you're not a lefty John.
I butchered the palm side of my left index
finger about 3 months ago. From the tip
to the second joint, down to the tendon.
Did it with a bench grinder-wire wheel.
Being a lefty myselfe, writing was out of the
question for weeks. Still wating for the nerves to heal.
Didn't cry when it happened, but I'm crying now.
Waa waa waa. Sorry. Embarassed
My DNA is all over that wheel.
As a consolation prize, you win Small Cox Logo engine scar of the month. cheers

Thanks for the prize Bob.
I wonder what I'd get if I was stupid enough to fire it up
One last time and stick my right thumb in just for
Good measure.....
