Vintage Calipers from 914-6 #11, ...the very first 914-6 to leave the factory Options

[Eric_Shea]

Well, we received the calipers to restore for #11. This is the very first 914-6 to leave the assembly line. The car was used by the factory as a demonstrator car. They loaded it with all sorts of go fast and stop fast goodies.

In the go fast department this car received a 2.0 twin plug motor.

In the stop fast department we will see some odd things. I noticed a bunch of "little stuff" that you don't see every day on your standard 914-6.

Let's start with the rear. These are the real deal. These are real factory 914-6/GT calipers and I would dare say the very first set. Here's some of the standout differences from your standard 914-6 or even later GT calipers.

#1 - These have the 911 M-Caliper hardware for sure. The first thing I noticed was the Ribe head cap screws with the R6 head. This differs from the rounded shoulder Ribe R5 hardware used on the 914-4 and 914-6 calipers of that era.



#2 The next thing I noticed was the spacers. These are the round shouldered spacers from an early rear M-Caliper of that era. Later GT and Ferrari calipers have sharp or squared off spacers that better match the caliper mating surfaces.



#3 The final note (of distinction) for the rears would be the color. It seems as though these are definitely "yellow" cad plated. On other 914-6 calipers it was difficult to tell because they were so light. When we tear into them we can usually see some yellow on the mating surfaces but, again, it's very light in color. These look to be 914-4 yellow in color, meaning; very obvious.

Thanks for the little items that make the difference.

Now for the fronts...

S-Calipers. Early S-Calipers.

Most S-Calipers have the rounded off bull nose. These S-Calipers have a more squared off nose with little casting wings on them.



Here's a shot of a bull nose S-Caliper side-by-side for comparison:



Notice anything else? How about the color? Again, most S-Calipers have a greenish gold tint from a sealer used in the anodizing process. These early calipers are simply anodized aluminum. Here's another side-by-side for comparison. 914-6 #11 on the left, later model S-Caliper on the right.



Here's some wierd notches that I'm still scratching my head over. These are just on the left caliper... anybody? (IMG:style_emoticons/default/confused24.gif)



One more showing both...

Maybe they were a prototype that got changed along the way? Maybe they were borrowed from some other European car model on short notice?

I can look for those notches on my Dad's 911 this weekend if I can make it home . . . his 911 seems to have early S calipers like those. They are even the same color (atleast thats what I remember them looking like when we rebuilt them).

Are you talking the S-Calipers? I don't think so. They should have had S-Calipers as standard equipment the previous year on all 911S's. Only the left caliper has those notches... (IMG:style_emoticons/default/wacko.gif)

Guess I've been sleeping. What/where's the story on the restoration of #11? A thread here? Somewhere? I wanna know more. Please!

[Eric_Shea]

#11 was recently purchased. It was in storage in a barn in Pennsylvania. The factory commissioned it off the line as a demonstrator car. It was then given to a friend of the family here in the states. Gary Wigglesworth bought it off that individual and stored it for nearly 20 years (maybe more).

It was recently purchased from the Wigglesworth estate, along with a bunch of GT goodies, by an associate who had us do his original GT calipers.

I've been trying to get Pete in touch with him to do a full story on the car as I feel it's one of the coolest, one off 914's in existence.

This is wonderful stuff Eric.

Working with original pieces like this must be a real treat.

Precious cargo i would say.

And the precursors of what was to come. Very Kewl.

Very solid pics and descriptions.

Thanks,

Clayton

A member here has #12. you should contact him and see if his has the same or different calipers. (GMS)

[Eric_Shea]

Yeah... I don't know too much about Glenns' car. (IMG:style_emoticons/default/confused24.gif)

Eric,

Would this have been the Stunden car?

Pat,

I'm not sure. (IMG:style_emoticons/default/confused24.gif)

Probably someone like the Dr. or Wolfgang might have more historical info on this car.

[Eric_Shea]

I found some pics of the Stunden car lately... this isn't it.

I dug into the first S-Caliper this evening... man, talk about bad shape. Don't leave your cool historic Porsche sitting in a barn. Everything came apart OK though. It was a task. Pics tomorrow.

Thanks for sharing the pics!

I'd be curious if the brakes from 914114 are the same... (IMG:style_emoticons/default/idea.gif)

I wonder if Sam is around to take some pictures.

I would doubt it. I think it depends on the engine. Others here could tell us what engine that car has.

The strange things about #11 are:

1. It was the first "production 914-6" listed off the line.
2. The factory grabbed it as a demonstrator car.
3. It was a factory hot-rod (2.0 twin plug)

I think because it was a factory demonstrator car and a hot-rod, so to speak, they decided to put the best brakes they had on it.

A little shop research last night:

I found another S-Caliper with the casting wings "but" it was post 1971. If you look at the second picture in post #3 you'll notice two circles on the top of the later caliper on the left. Inside those circles is stamped an "X". While looking at the factory manual this denotes a new piston and a date range later than 1971 (I believe... manual not in front of me at the time of this writing). I found one of the early style calipers (wings) with the circles cast in it and the X's... (IMG:style_emoticons/default/idea.gif)

Here's some wierd notches that I'm still scratching my head over. These are just on the left caliper... anybody?

A pockect for the keeper. so the pad can retract further. 1.5 extra pad for endurance racing. or as stated protype , fittment issues

[davep]

here is my oddball caliper

908?
