V12

[DannytheRadomski]

So I was just daydreaming about the WWU V8, and I was thinking about a V12. Now the proper thing to do would be to build an Aston Martin go-kart to house it. The pistons I'm thinking about using (if I ever do this) are either the same ones from the WWU V8 (250cc four cylinder Kawasaki ninja engine) or 50cc pistons. The diplacements for these engines. would be 750cc and 600cc, respectively. This is really just a pipe dream, but any input is helpful.

why not 20 cylinders?

[Cardriverx]

Should be easy, just a little JB weld and duct tape, maybe some zip ties.

Just the other day I took a couple rotary engines, stacked them up to make a 10 rotor, and JB welded them together. Most badass sounding engine I have ever herd. Too bad they don't allow rotaries at comp!

Honda made a 5 cylinder 125 road race motorbike back in the 60s. If you could find five of them, you could stitch them together you would have a bitchin 25 cylinder engine.You would use a turbocharger per bank of course.

PS.
Okay, I know it might be a few ccs over in capacity, but no tech inspector is going to measure all 25 cylinders.

[rjwoods77]

Well if you are assuming basing it off available cylinder heads then your capacity will be tied into that. That being said there is probably no better engine to do it with then a Honda CBX 6 cylinder and it has been done....

Nice that the cylinder heads are center chain driven as to avoid asymmetry like other engines that have used dual cylinder heads. I can't imagine what the thing would sound like in full boil on a track since the 6 cylinder with a 6 into 1 exhaust sounds like ICE sex...

[DannytheRadomski]

I like Cardriverx's idea. I had heard about a twelve rotors, but Ithen heard it was a myth.

[AxelRipper]

Well its simple... just take 2 of these and slap them together...

[DannytheRadomski]

Oh yeah, I have a few of those laying around. I kept forgetting why I kept them.

[rjwoods77]

Not a myth...

Honda CBR250RR engines might make a ‘good’ base to make a small v12 from. The cam drive gears are placed in between cylinder 1 and 2 (or 3 and 4, I’m not sure), so you could lop the outer cylinder off two engines and join them to make a straight six, then combine two of those to make a v12.

Suzuki made a 3 cylinder 50cc engine with a 14 speed gearbox for 1968. Unfortunately it never raced because the rules were changed to restrict the 50cc class to single cylinder engines before the start of the season.
If you could find 12 of them you could make a 36 cylinder 600cc engine, if the tech inspector asks why you’re running a 2-stroke just tell them it would be a prick to adjust the valve clearance on 36 cylinders.

Ah the joys of a 6 http://fsae.com/groupee_common/emoticons/icon_smile.gif

My straight six sounds more like a tractor...
I must be doing something wrong.

For this solid argument the team should be allowed to run.

[PatClarke]

Far easier to find model aero engines! 5cc engines would allow you to fettle 120 of them together, maybe run them through a CVT and call it 'Formula ridiculous'. Might need several turbos though.

Edit...and if you needed a bit more power, you could add two more and still be legal http://fsae.com/groupee_common/emoticons/icon_biggrin.gif

[AxelRipper]

Pat, do you think we could get a pass on the fuel type/ Cycle count regulations for something as ridiculous as that?

Following Mr. Clarke's suggestion of 5 cc model aero engines: 3.5 cc model car or marine engines were more powerful in my RC modeling days http://fsae.com/groupee_common/emoticons/icon_biggrin.gif
With 174 of these, you could make some 560+ hp (assuming the judges could be convinced that is is too difficult to route 174 inlets into one restrictor). Of course, you could always add some superchargers to improve on that (turbos on a 2 stroke? No! http://fsae.com/groupee_common/emoticons/icon_redface.gif ).

EDIT: Weight of that 174 engines would be about 60 kg, in the range of 600 cc 4-cyl bike engines... The only slight downside: Cost. 174 Rossi high performance 3.5 cc engines = about 72723€ (or $ 93216) - One might need a good sponsor...

[Will M]

Or you could JB Weld 12 of these together.

[2 cylinder, 50cc, 4.7 hp, 3.8 lbs] X12 = [24 cylinder, 600cc, 56.4 hp, 45 lbs]

Cost: ~$12,000

[AxelRipper]

40 of these:

(Single cylinder, 15cc, 1.6hp, 1.6 lb)x40 = 40 cylinder, 600 cc, 64 hp, 64 lbs.

A bit heavier, but more powerful, and only costs $9200.
