Value of a 1976 2.7 Carrera

[rsnodgrass]

I've done quite a bit of research on the 1976 Carrera 2.7 and haven't come up with anything that indicates these were for racing homologation. This includes looking at all FIA paperwork I could find, discussing with folks at the Porsche factory archives, discussing with Porsche engineers who worked at factory in 1970s, digging into any paperwork I could find, studying photos of almost half of the 1976 Carrera 2.7 production, etc.

Note that manufacturers had to homologate cares for road use as well as racing. I believe what George K saw from Switzerland was the road going paperwork. Racing homologation was always done through the FIA which was the international sanctioning body. There would be FIA homologation paperwork or extensions filed if there was truly for racing reasons. I've found no extensions to the FIA #3062 homologation paperwork which was used to homologate the Carrera 2.7 and the later 911 SC/RS in the 80s. I have contacted the Swiss homologation authority and AMAG (the importer) several times and have never been able to get any paperwork from them. I did find a copy of the Swiss Carrera 3.0 homologation somewhere. Also, from what I understand all 1976 Carrera 2.7 were delivered through German dealers only. While a Swiss person could have purchased them through a German dealer I don't know how that would Swiss road homologation would work in that case.

The 1976 Carrera 2.7 is unique from the previous two years in that it is actually a type "911" instead of a "911 SC". This can be noted on the aluminum chassis tag. The 1976 "911 SC" was the Carrera 3.0 (and the 1973 Carrera RS was also a type "911 SC"). This important distinction means that the standard options were based off the 1976 base model 911 which for the German market included only a single mirror, clear class, non-luxury interior including both the rougher style carpets and simpler door trim without stitching or carpeting, manual windows, reverting to chrome trim as standard per base 911, etc. In a way I think this makes the 1976 even more interesting and rare than previous models as it was a more stripped down version of the 911 which was then built up with Bilstein suspension, engine, LSD, 5-speed 915 with mechanical speedo (also used on RoW base 911 in 1976), plus adding flares on a base 911, etc.

Now they could have been built to somehow homologate the MFI engine for the base type "911" model which was under a different FIA homologation #3060, but I don't know why that would be necessary given the "911 SC" itself was homologated with the 911/83 engine.

That's a quick summary of what I've discovered thus far in my research. I welcome ANY additional information, original documents, etc. as it hasn't been easy (or very cost effective for me!) to track down the info that I do have.

I hope this sparks some new conversations and discussions around this very unique model.

We now have another theory from Elferfan that supplies of the Carrera 3 engine ran out which is plausible as the 2.7s were all registered around July at the end of the 1976 model year. The same series of MFI engines were used in the Belgian Gendarmerie Targas, does anyone know exactly when these were supplied?

Thank you for your answers and comments.

My mechanic also told me that Porsche used spare parts to build the 1976 Carrera 2.7 model. Even if this is true, it does not explain the reason why they did it. The extra cost of defining a special model with a dedicated VIN range should be higher than the benefit of using some spare parts. I don’t know any other example in Porsche’s history where they did something similar. A reason for the 76 series could have been customers requesting a more “sportive” Carrera model as the ordinary Carrera became more and more comfort oriented.

I have never seen any sales brochure or original purchase document about these cars. I am wondering how they were officialy called.

Could be, that the 76 Carrera was based on the normal 911 2.7 of 1976, but even the base model of 1976 came with the more elaborated door panels.

Regarding the differences between the ordinary Carrera 3.0 and the 2.7 already mentioned in this thread, I can confirm:

- engine 911/83
- mechanical speedometer (max. 300 km/h)
- simple door panels like 74 standard version without carpet
- manual windows
- simple non-luxury carpet
- no electric heating system
- special steering wheel
- no Carrera badge

I haven’t checked until now:

- LSD
- less sound prooving
- Bilstein sport suspension
- roll bar mounting plates

The car has only a left side mirror and non tinted glass, but this was also the standard for the Carrera 3.0. The interior seems to be equal to Freisinger’s car.

Head light washers (standard for Carrera 3.0), the left side antenna, front speakers and the chrome trim are options. As far as I know, the Cibie lights were never a factory option, but often installed by the dealer before delivery to the final customer.

The car has a 2 grill tail and the way how it is mentioned in the original title makes me believe it was there from the beginning.

My car is equipped with A-caliper front brakes like the Carrera 3.0.

Interestingly, the car has an official max. speed of 245 km/h mentioned in the title. This is higher than the Carrera 3.0 (230 km/h) and even the Carrera 2.7 from 74/75 (240 km/h).

A strange thing on my car is the design of the Fuchs wheels. I have never seen this black on white layout before. Does anybody know something about it?

I hope this information is useful.

[rsnodgrass]

elferfan,

Your theory on the "sportive" version sounds plausible.

By special steering wheel I assume you mean the Sport steering wheel? Also I think the Carrera badge was available to delete...I haven't noticed any other 1976 Carrera without the Carrera badge (but I should go back and check!). I think the whale tail was standard, but could be deleted by the customer.

Thanks for all the info on your car!! This has been great. I too have never seen the unusual Fuchs pattern before. It looks like your car has 7 and 8s, is that correct?

There are NO roll bar mounting points on any of the cars I've inspected in person (at least six, perhaps one more that I've forgotten). Further none of the photos of restorations that I've seen indicate any roll bar mounting point or reinforcements were in place. Also it seems like there are a large number of metallic cars produced...if you were producing cars for racing it wouldn't make sense to produce cars with paint that would be difficult to match (and more expensive) for inevitable bodywork.

Ryan,

the car has 6x15 and 7x15 rims with practically "new" Pirelli P7 tyres. Unfortunately the rubber got hard during the years.

I am not sure whether I will keep the 6/7x15 or switch to 7x15 and 8x15 combination which is also allowed.

For the 6/7x15 combination Pirelli offers the P6000 N2 with 195/65 front and 215/60 rear. The 7/8x15 combination requires 205/50 front and 225/50 rear. I couldn't find any real good tyre for this size. The P-Zero is available for 225/50 but not for 205/50. Any recommendations?

[rsnodgrass]

What are the tire sizes for your existing P7s? Do you have any photos of your wheels facing on? Would be neat to see them!

[elferfan]

I cannot tell you right now the actual size, but I will check it tomorrow.

[GWhite]

Elferfan,

The 195/65 and 215/60 combination can also be used on the 7&8 inch wheels. Pirelli also produce the P6000 N2 in a 185/70 size. The original fitment for the Carrera 2.7 and Carrera 3 was 185/70x15 front and 215/60x15 rear on 6&7 or 7&8 rims. The 205/50x15 and 225/50x15 P7s were an option (M395) on the 1976 Carrera 3 but with an adapted speedometer to allow for the lower rolling circumference.

Guy

[elferfan]

Guy,

do you know how this adaption of the speedometer can be verified? Is it a different speedometer with a specific part number?

In the title of my car there is mentioned "Tachoangl. NT. 9116+1 53000". This could refer to an adaption of the speedometer.

[rsnodgrass]

Supposedly on the tachometer itself (when removed) is a sticker on the bottom side that indicates the calibration of the tachometer. I don't have a sticker on mine, so don't know if this was only done when they were calibrated differently.

[GWhite]

Elferfan,

The 1976 Carrera 3 had a different speedometer (Part no 911 641 501 00) when the 50 series P7s were fitted. The C3 though had an electronic speedo whereas the '76 C2.7 has a mechanical one. If the 50 series tyres were fitted to your car then I guess the original speedo would have had to be adapted but I don't know what the normal practice is to specify calibration.

Ryan,

Thanks for sharing your extensive research on this model. Seems it was not homologated for racing then. Seems unlikely though these were just a small group of coupes produced to use up parts or they ran out of 3L engines . I too think a 'Club Sport' type model makes sense. These may have been the first type of 911 like the CS or the 964 C4 lightweight that Porsche produced.

Do you know what these sold for when new and how they compared in cost to the other '76 models?

Another tire you should look at is the Avon CR6ZZ. They come in 185/70 and 215/60 for 15" wheels. I plan to put a set on the RS this year.

I'm still hoping someone uncovers a holy grail document that shows racing homologation, but I've exhausted where to look! The "Sportive" or Club Sport theory is a really interesting one that bears more research and thought. The '73 Carrera RS was, IMO, the original Club Sport type model...marketing didn't think it would sell, too stripped down, etc.

[fryardds]

Ryan,

Do you know what these cars cost when new and how they compared in price to the other models?

Can you tell me how the flares were put on these cars? Are they welded on quarters like the early '73 Carreras? Thanks.

[rsnodgrass]

The flares were not welded on like the 73 RS and early 1974 Carreras. I'm assuming the rear body panels were shared with the current Carrera 3.0 production as they were now making them as a single piece.

GWhite,

The 911 641 501 00 speedo you note is for the 250kph speedo 1972-1973 MY (...501 29 for 911 & 911S models / 1974MY - 1977MY *except for Japan market*).

The correct C3 (elect.) speedo for fitment with 50 series tyre (M395 option) is '930' 641 501 00

There was a specific mech. speedo built & calibrated for factory fitment if M395 option was ordered on a 76MY C2.7.

The unit that would be fitted by the factory 'IF' a 76 MY C2.7 was M395 optioned , would be no. 911...641 530 00

[rsnodgrass]

FYI, one of the 911 641 530 00 speedometers just sold on eBay yesterday. Porsche 911 Tachometer Tacho 300km/h mechanisch 2.7 RS, 3.0 Turbo 91164153000 | eBay

You are correct Ratbox force of habit of putting 911 as first digits of part number.

I note the 911 641 530 00 is shown in the '73 parts catalogue as for 50 series tyres but does not appear in the '74 to '77 version.

[elferfan]

For completeness I post 2 pictures of the interior of my car, which I took this morning. The condition is still how I got the car without any cleaning or cosmetic. It seems to be very original. Also the speakers seem to be from the 70's.

@Ryan:
the size of the P7 is 205/50 VR15 front and 225/50 VR 15 rear.
