Mini V8? Could it be done, easily?, Thinking outside the box again Options

[alpha434]

you guys are funny. You wouldn't double the horsepower and maintain the same redline just by sticking two engines together. You now have twice as much rotating mass and more strength deficiencies in the case. You don't even have roughly the same characteristics of 2x one engine. Period.

geez guys!!!!!!!!!

how can you just ignore him like this?


such prime flaming fodder!

THAT NEW ALPHY MATH! 100+100= 70 is that right alphy?

100+100 not= 200, that's right.

I was thinking something along the lines of an 83 1100 Honda Saber at 118hp per engine. The magna (of which I owned one) had the fastest produciton bike speed record with this engine. I am pretty sure the V-max took its place, I wonder what two of them put side to side would do? (IMG:style_emoticons/default/idea.gif)

[Dr Evil]

Yup, now coveting the V-max engine. 1200cc, 145hp, 9k redline. Small (fits between your legs), light (whole bike wet is 651#), cool, powerfull and relatively unchanged since its inception in the 80s = proven (IMG:style_emoticons/default/biggrin.gif)

Why not just save the weight and go for a single 1300 cc turbo Hayabusa. They can easily make over 300 HP. Lots of cars are using this powerplant. I have even seen a VW Golf with one.

here is a site that shows some cool conversion work.

Yup, that was the kind of stuff that spurned the idea, but it violates the one tenet of cost. To get the busa, hop it up, etc = $$$. Two V-max engines form a salvage yard, some welding of a cradle, a coupler and some inventinve engineering and presto! I realy need to live in a place with a barn for my crazy experaments some day. Every evil genious needs a layer.

What is the tq out of the busa engine sup up to 350bhp?

[PinetreePorsche]

Seems a lot easier just to do the Subie thing--a 4 like the one in Excellence or like Ed Hunziger's. Highrer revs, almost unlimited power, if you add the blower ;like the WRX. OK--it's been done--but done enough to be very reliable and pretty easy, and relatively cheap. No one is going to mate to mc motor cases and cranks for less than 30 or 40 Grand.

[Dr Evil]

Clayton, thanks man. You said it, and enough said about that. (IMG:style_emoticons/default/thumb3d.gif)

PinetreePorsche, dude you are missing the point. And 30-40 grand?! Better come with a happyending of the oral kind.

Box, meet your company, now feel free to think outside it if ya want to (IMG:style_emoticons/default/rolleyes.gif)

I love this crazy stuff. (IMG:style_emoticons/default/aktion035.gif)

I'm not sure your concept would be best served in a 914 though. I would build a mid engine light weight tube chassis and skin it in aluminum. There are tons of cheap wrecked 1100 cc bike engines out there. Most bikes have great hp but lack torque to get a heavy (by go cart standards) 914 moving. The clutches are not designed for the severe duty required to move a car and passangers.

I would mount the engines sideways, remove the alternator and clutch covers, add double or triple row sprockets and chain the ends of the cranks together. Then the second engine in line you could connect to a drive shaft like the Legend cars do.

[messix]

i think putting some thing like 10 chain saw engines together would be awesome!

[grantsfo]

How about two Harleys?

[messix]

that could be timed to sound soooooo wicked!!

[grantsfo]

I like this site. Good potos of engine build, diagrams, sounds, etc

[Dr Evil]

Now yer talkin! Thats cool.

I was figuring the hardest part would be keeping the tq required to move the car from snapping any clutch/plate combo. I just need to feed them into a diff like the twin Harley thing (IMG:style_emoticons/default/biggrin.gif)

[spare time toys]

Check zcars.org they have kits to stick a suzuki engine into a mini as well as honda r series ones (IMG:style_emoticons/default/piratenanner.gif)

Hayabusa and Honda Fireblade engines are pretty common in tube-framed and aluminum skinned Lotus Seven replicas too:

And why stop with an 8? A flat aircooled sixteen, now THAT'S impressive!!

[huh? Why isn't that image showing up?]

But Doctor, the original question was if making a V8 out of two fours could be done "easily". I think the answer is no. Machining a new driveshaft and block to use the motorcycle heads? Sounds a bit like that Yamaha built Taurus SHO engine, but for some of us to do? Not easy. Then in the V engines there's one flanged or splined crank drive output, and generally the other end of the crank only drives an alternator. That end isn't strong enough to drive or be connected to another engine end-to-end and still transmit any amount of torque that would be fun. You could configure the engines side-by-side and gather the torque with a belt drive to a common shaft, I suppose, but then you've got a real big engine package and are again pretty much out of the "easy" category.

Yea, now if they would just make a Boxer-8 version of that engine! That thing is sweet.

I like the idea of the Honda V4's coupled together though. Those are some wicked engines, never fully appreciated.
Or how 'bout a couple of CBX engines tied together? V (or flat?) twelve??? (IMG:style_emoticons/default/blink.gif)

[i love porsche]

heres a mini V8, 548 CC displacement, using Ninja 250 Heads...not exactly what youre looking for, but pretty cool, used in WWU's FSAE car a little while ago.

[DBCooper]

OMG, that's absolutely incredible. Did YOU do that? Amazing.
