I remember no too long ago someone posted a bitchen link to a mini V8 made from 2 hyabusa engines. It was a great idea, but out of the price and consideration range for probably all of us. This got me to thinking, though. The hard part is having to cast a block and a crank to fit the hyabusas together. While this engine is by far the bset choice for car applilcations due to its overwhelming power, there has to be another, easier alternative.
I was wondering how hard it would be to take 2 honda V4 1100 engines (pretty common and easy to get) and make the out put of one to the shaft of another. This would remove any need for a contiguous case/crank and yet serve the same purpose. The hondas came to mind because it is what I am familiar with in teh V4 configuration. They would be compact, easy to plumb, high rev, relatively low maitenance, and high in cool factor. Or, how about mating two large V engines together = more tq, lower reving, air cooled (or not). With the ponies that the motorcycle engines are pushing these days, adding 2 togather would give a light car like ours a nice boost and probably be lost of fun. Any thoughts? If I had it my way I would mate two BMW K1100 16V engines together in a flat opposed 8 configuration, but thats a bit out of my skills level. |

Didn't we have a thread on this? Where we bashed me for an entire night for saying that it was possible?
It's been done numerous times before. with many different types of engines. |

QUOTE(Dr Evil @ May 27 2007, 03:33 PM)  Any thoughts? Aside from the cool "Look what I did" factor, I am not sure that I would see the point of it. Depending on the person, though, the "Look what I did" factor can be one hell of a draw. It is the reason that many of us rebuild these cars. I know that 'Busa engines have been put into Minis (old body, not current) and Smart cars, to great effect. But bolting 2 engines together for a 914 would probably be more hassle then it was worth, with all the other good and "relatively" cheaper options. In the end though, all it takes is money and time.

just weld two type 4 cranks together and make a nice 3.4L out of two old 1.7s ... (IMG:style_emoticons/default/welder.gif)
nothing like a aircooled flat /8 !!! (IMG:style_emoticons/default/smilie_pokal.gif) Andy |

Did the 'factory' flat 8 914s have the trunk cut?

Hey man, dreaming in free!
Actually, with 2x 1100 V4 engines you could get 200hp and a 8-10K red line in a compact package. All I am thinking is a crdle to hold the two bolted together, and run the radiators in cool looking ducts in the side behind the doors. The engines are not much $$ at all. Who will do it? Maybe me some day, but by then I will likely be forced to mate two hydrogen cell engines together... |

Good question of the factory 8s, I have no idea how they fit that in there and had the transaxle not poking out.

I was just considering your welding of 2 1.7s together and it would only = about 140hp....but it would look neat (IMG:style_emoticons/default/wink.gif) At least the bike engines would put out more.
How the hell do ya get two cranks welded together? The engine would be very long (IMG:style_emoticons/default/biggrin.gif) |

Danke!
Ya, while Im in there (IMG:style_emoticons/default/dry.gif) Two mated TIV would be even longer. Sounds like the prefect engine for the 914 limo that I have been wanting to build. |

Add another rotor (3) and put yourself in the 350 hp range... Then you can turbo it...or add yet another rotor or both... ....if small lightweight, high HP, high revving engines is what you're after.... I've even seen the thread on putting a rotary in a 911..... |

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.
