Porsche 908 and Related Research

[scootermcrad]

Hey everyone! LONG time lurker, but find myself posting today with some unique questions.

Although I know my way around early air cooled 911 topics, I have found myself doing some research on Porsche race cars, specifically the 907, 908, 910, and related mechanical components. After doing a few searches I'm coming up empty (no surprise). But then I could be doing it wrong. HA! So hopefully I can get a little help or at least maybe some contacts, links, or some other resources to help with my mission.

I'm looking for more information on suspension components, geometry, etc. It seems these handful of cars shared many of the same components; uprights, brakes, control arms, steering, etc. Seems even some of these driveline components may have carried into the later 934/935 platforms. Related to this, chassis details, specifically for front and rear clips would be helpful.

Any details, specs, pictures, cross-utilization between these series or others, would be very helpful. Any links to articles maybe not easily found in a Google search (done lots of those), maybe threads I couldn't find here, or even books or articles. Anything. I'm also wondering if Porsche developed any of these components with 3rd parties that may have found their way onto other makes (I'm guessing I know the answer to that). One of the hardest things I seem to have troubles with is finding pictures or details of just the suspension components themselves and I definitely don't have access to a car to look at, but may plan a trip to see one if possible.

I know I'm being a little vague in my asking. I'm not building a replica of any of these cars, but I have been researching an extremely unique car that may have used these components and I want to understand more about what they did when they built the car. it's just a little engineering research, if you will. But it could lead to semi-replicating a historic race car that seems to have disappeared.

Thanks for any help, everyone! It's appreciated!

Besides the two basic books, which you probably already have...

I'd give these two shops a call... See if they can set you in the right direction....

Thanks for the response, Chuck! I really appreciate it.

I'll reach out to Canepa and Gunnar. Gunnar has actually been on my "shops to visit" bucket list for a long time. May need to plan a visit. I know Rod Emory has had his hands dirty with the above mentioned cars and I'm planning a trip next year to chat with him while I'm out there.

What I've run into in the past when asking "race car questions", is less about the availability of information and more about the unwillingness to share. So I'm trying to be careful about how I approach this.

Well this includes yourself.
If you don’t give information why should others do? Post pics of the parts in question and I‘ll bet you‘d have an answer whether they are Porsche parts or not.
They way you‘re asking I would hesitate answering as well.

Yep. That's fair. I was trying to be a little vague because I don't have a lot to go off of except the story I have about the car which apparently (or most likely) used 908 suspension, wheels, and it appears maybe parts of the front and rear clip, or the geometry was replicated for this application.



The question is really less about the exact parts used on THIS particular car and what COULD be used to achieve the same geometry. Obviously 908 parts don't just grow on trees these days, so I'm trying to understand what comparable parts could be used if not specifically from a 908.

Hopefully it makes a little more sense why I'm asking, now. I don't want to focus so much on THIS car, (because I'm pretty sure those are 908 outer corners), but what else could be used to achieve the same geometry, rather it be a 910, something aftermarket, something new and available today, etc.

I'm actually considering doing a build inspired by this car for THIS era (mid 1970's) and I want to be faithful to what was done with this car. But I need to see what I'm up against and the availability of comparable parts to keep it faithful.

My comment regarding "the unwillingness to provide" was related to owners of historic race cars not wanting people around their cars. I'm just trying to understand what was being done by Porsche.

It's especially exciting when I see someone actually cut up two factory Porsches to build one race car from the two. But in the case above, I don't believe this car exists anymore or I most likely wouldn't ever see it. So understanding the geometry of what went IN TO the car is the objective.

The 906 etc. geometry is known. There are enough companies building replicas.
Simply checking the homologation forms shows pics of the suspension.

Now that's great information! Thank you!

Was the 906 geometry the same or similar to the 908/910? I was thinking the uprights were pretty different, but maybe not.

Yep! UAI above linked me to the same place. Thank you! I appreciate it.
