The Ultimate T/R Thread...

Here are the ones I have on the ST. Magnesium and original from the period, and with a lip:

bump...please update! :)

This appears to be the same factory light weight rear seat back as seen in the Hamilton car.

It is laid up from GRP with black gel coat. The outside is sprayed in black flock similar to inside glove box texture, unlike the cloth covering seen on the Hamilton examples.

Tim thinks this may be a factory Group 3 bit for saloon car racing.

This looks like something that Bob could repro for the ltwt '68 crowd!

I have some details on the 911T (1968) rear seat backs which were offered in the 1968 Sports Purposes outline, under Kit No. 9553, this kit was for 911T for use in Group 3. The description of the back is listed as "simplified rear seat rests" no part number given. I assume the backs were part of the Kit only. The front side is black flocking, the frame inside is aluminum with steel rivets, and the inside or back i'm not sure, as the example i have, has a carpet meteral that was added later on. under this carpet the paper is black in color. Maybe original had no covering at all, like photo in above post. the seat back is made of paper, like paper mache. Yes same as glove box, door pockets ? The back is 597g. in weight, with no carpet/perlon. You can see several layers of paper in the edge photo.

This car for sale currently at elevenparts in Switzerland http://www.elevenparts.com/index2.php?f=cars has made me think about where you draw the line with early sports purpose cars that were not "official models" but rather cars that met homologation standards but could have been made that way by the factory or converted privately by a factory supplied kit of parts. The T/R and S/T fit squarely into this category and have generated lots of posts on this board.

This particular car is not described as a T/R, and the engine number is not provided, although one photo shows a stamping of "901/22" on the engine suggesting that it is the sort of engine that may have been in a T/R.

However the description "1968, Porsche 911 T Gr. 3 (4) " and the detailed description of it starting as a 1968 T but in 1969 taken back to the factory race department and converted into a full race spec Gp 3 car, and then successfully competing in that guise and category at the Targa Florio in 1969 and other places and then being upgraded to Gp4 standards later (but not by the factory). I think that I would categorize it as a T/R given the looseness of that classification and the clear intent of the car to be covered by the homologation to that level. However the chassis number, 118 2 5233, is interesting as it is the only Karmann built car (designated by the 5 as the fifth number) on my (very incomplete) list of T/R's and potential T/R's.I would be interested in others views on this, and even if it should be considered as a "factory constructed T/R".

Even if it was not born as a t/r from new, I would say that this car is as good as they get, and with a very important racing history!
10th OA and class winner at Targa Florio makes it very special IMO, and the later gr.4 history is interesting as well.

Great car.

Hi!

Can anyone help on Getting an exact description of the "Interior M471 Lightweight"?

Thanks in advance!

Hello,

I am new on this forum and I am looking for informations about the TR oil cooling system.


I can see two configurations for the 911 TR oil cooling system / oil lines and :

Page 6 : Hamilton TR is fitted with 911R oil filter housing, hard oil lines are insides the rocker panels. The 911 T/R "Out of Africa" is in the same configuration (Correction : no front oil cooler for T\R "Out of Africa")

page 9 : 911 TR "Hart Ski" is fitted with 911 S 69 - 71 console + thermostat, hard oil lines are outside the rocker panel.

What was the oil cooling system configuration of the 25 "Factory" TR ?

What was the outer diameter of the hard brass side oil lines : OD = 18mm or OD = 22mm ?

1 or 2 front oil coolers like the 911R with M26x1,5 connectors ?

Thank you for your help

The answer to your question is that the "factory" cars had any one of three alternatives depending on their intended use. Some left with a standard road set up, some with a single cooler in the RHS front wing and some with the double cooler 911R set up. These cars were not built to a standard factory spec but rather to the customer's instruction. I doubt there are two the same. The factory document "Information Regarding Porsche Vehicles Used For Sports Purposes" gives you a full explanation of the options that were available at the time. It even provides advice to customers as to which options were eligible for different FIA homologation categories (Group 2, 3, 5 etc). I'm sure the document has been posted on here before. Someone might be able to point you to it via a link.

I was at the gas station ('servo'/'garage'/fuel stop) this week in my 911 and a young guy pulled up to admire, and mentions he has a a T/R '68.

I am sure that car has been on this thread some where. The car is about 10 kms from here. http://passion.porsche.com/au/articl...on-1968-911-tr
