Technical specification book.. what is it?
 

Can someone tell me what this is for? And if it is worth the ~$45 USD??

If you have the Official Porsche work shop manual, you already have the specs that are in the Tec Spec book. The Tec Spec book is a pocket book that has all the specs in one place. Everything like torque specs, alignment specs, engine tolerances etc.

Probably a good addition to Bentley or Haynes.

I would keep that, no longer available.

It's just a neat little addition to your other manuals, etc. I would pay $45 for one if I didn't already have one.

Did they make a book for the 87-89 Model years?

The one you showed at the top does cover '87. It's written on the cover...

Which doesn't makes sense... because there were major changes to transmission in '87.
I don't want to get this book to find out it 'assumes' that what worked in '85 applies to '87, which sometimes doesn't.

hi it make sense...911 1984-87 Carrera is the book for your 911.No they did not made any other books until 1990 for C2-C4...

I would think they would not have forgotten the G-50.

Would be nice if someone that had one would take a peek.

Bob, the 87 is already with the info for G50 trany

Thanks for the confirmation. Not like Porsche to forget this sort of thing.

I did search around a little bit to see if there was an extension for 88-89 and 82-83. Found nothing.

I do think I saw that the 964 starts in 89 for the C4.

Enjoy your weekend.

yes ,October 1989 was 1st C2 made ........as of any 911 years anything October plus is already next year production ;-)

I use these two books the most for helping people here if I can. I hardly need the other pile with info contained in this forum.

That is an original Redbook. They are expensive.

If I ever sell I will describe the coffee stains and grease as "patina"

I reference mine a lot, definitely worth $45 in value, although should just be a $5.00 phamplet! Supply and demand

The book references G50 stuff in the table of contents.

EDIT: I guess I should have read all the way to the end before posting a duplicate to Matt's...

Any self respecting DIY should have one for their car SmileWavy.

Just kidding.

It's packed with technical goodies worth the price. If you don't mind the grease, fingerprints and stains, you can find them cheaper used.

They have a lot of cool stuff in them. Every spec, in one place, and then some. Essential if you are going to take an engine apart, certainly. Fascinating book for engineers.

Anecdotally, there has been at least one robust discussion on this site about the claimed volume of air moved by the cooling fan. From my Spec Book: 1500 l/s at 6000 rpm. Yeah, that's liters per second.


7000 rpm (+/- 200) is my rev limiter. That's interesting to me right now. Thanks for making me get out my Spec Book.
