I know it is a long shot.
I have started to model up a 4.5 liter 12 cylinder 917 engine. I am using a few drawings I have found online and pictures. For scaling purposes I have used some known dimensions like the stroke (66mm in this case) There are some components that would be nice to get better dimensions from such as bearings which if they shared 911 bearings that wouldn't be too difficult to obtain the numbers needed. The final goal is to have a 3D model so that anyone could print or machine a scale version of this engine for their own enjoyment! |

Well shit, why didn't you just ask. Got two 917s sitting in the garage right here next to the teener (IMG:style_emoticons/default/lol-2.gif)

From what I remember reading the 908 flat 8 and the 917 flat 12 were both 911 flat 6 based…

Just weld together two 2.2L /6 engines. That should get you close ...

I think Towle has one in his barn behind a few 911's, Beatles, and 356's.

Mueller,
Honestly though I am really serious about one day buying one of the 917 replica cars from RCR (look them up). Mostly, people put 911 flat 6 in them, but how awesome would it be to make a flat 12. Let us know what you find! |

One of the attendees of the old MUSR had a 917 crankcase sitting in his garage... I'm pretty sure he was able to clean the drool off of it after I left...

Canepa has a few of those engines in the shop, at least 2-3 in cars, and I think they'll be building/rebuilding one soon...

You could talk to Rich or Jerry at Jerry Wood's Enterprise in Campbell CA.
Last time I was there (15 yrs ago) they had at least 2 917 Engines and a 917 undergoing restoration. Jim |

Thanks Pete and Jim.
I would think with the brain power and resources Canapa has they would have a solid model of one of their motors already. (theirs or a customers) And if they did I highly doubt they'd share since it would been done on the clock! I'm not really anyone important to let into a shop to grab those numbers so I am not sure how I'd approach such an outfit, I'm just a guy in a garage with a small dream (IMG:style_emoticons/default/smile.gif) Maybe I'll scan my Type IV motor 1st, then I might be taken a little more seriously. I did scan this suspension part a few years back, pretty crude but the technology has gotten better and cheaper....hmmm, maybe I need some "investors", haha https://www.youtube.com/watch?v=FuTcyWqfqvI |

Small world, turns out a fellow Volvo nut works at Canepa, I'm going to see if he can snap some detailed pictures for me. Worse case is no, we'll see.

I phone Alfing Crankshafts in Germany, the original manufacturer of the 917 crank. They told me they would consider making new cranks but they would need to be ordered directly from Porsche. I asked for a drawing of the crank, to which they answered once again I'd need to talk to Porsche....

Are there improvements to be made such as material change or bearing size? (Smaller 2" SBC or Honda bearings?) |

Are there improvements to be made such as material change or bearing size? (Smaller 2" SBC or Honda bearings?) Yeah it was quite a hunt. Somone posted a pic of a crank with this symbol on it, really grainy, finally started googling the letters until I found ALFING. Like hitting gold! I don't think bearings are an issue. You can always have them made, and at the end of the day if you are making a repro 917 engine it's a one off anyways.... |
