930 Turbo Carrera

In the seventies, definitely not. I don't know about later cars, but I have never seen it on cars built between 1974 and 1979.

 

It sure is. I have two ultra low mileage original ones (under 5,000 miles '79 in my garage with it.) I have a friend who has a '79 with 40 original miles that has it. This was discussed on a old thread before with several pictures of several different cars of different years. It was also confirmed by Jurgen Barth.

Here is from the PCA website from John Paterek a top Porsche restorer and longtime National level PCA judge:

WE wse SKS grey then paint body color. Only early 91',s 65 -71 had satin black undercarriage. 930 turbos and some wide body cars had the wheelwells coated in matt black. John Paterek - Website - 4 /02

Here is a '77 that shows it:

Thanks for the info. So a body color painted underside would be correct for a 3.0 turbo?

 

Thank you for your kind offer John. Yes, I would love to accompany you for drive one day in the future. If you ever make your way downunder to Western Australia, let me know in advance and we can do a drive down my way.
Rgds,
Sean.

 

Hi Chris,

Great to hear from another UK '75 owner! We should get the cars together sometime.

I must admit to liking the Toyos on the car, but I will struggle not to go "authentic" when it is time to replace them. Plus, I am not sure I have the right size tyres to begin with since I believe there were two choices in 1975 on ordering and the one you go for now is determined by how your gearbox was set up then.

Standard was 930/30 transmission set to a final drive 4.222:1 for 15" 185/70VR front and 215/60VR rear. I know Dunlops were a period tyre (NLA) but according to Peter Morgan book Pirelli CN36 was a favourite with Uk cars. Longstone do them here

PIRELLI CINTURATO ™ CN36 | Longstone Tyres

But if your car was optioned with P7 for 15" wheels sizes it had a 930/32 gearbox with a final drive of 4000:1 and you had more grip and 18mm lower ride height.

It looks like you are in luck and those tyres are also available here if the size of the P7 option tyre was indeed 205/50 and 225/50

PIRELLI CINTURATO ™ P7 | Longstone Tyres.

The P7 only became standard with the 16" wheels, I believe.

I suspect, with no threads like this around, that this wrinkle about there being two different transmission set-ups on early cars got lost, somewhere in the last 41 years, and my car is in fact sitting on a size of tyre, chosen by a previous owner, that were not intended for the final drive installed.

That would explain why, tracking previous owner's posts on IB and PP, I see him asking the community about tacho running "fast". Lower profile tyre like the P7 and the Toyo presumably give a smaller diameter therefore a smaller circumference and that means, if my car was calibrated for the CN36s, my distances and speeds are being overstated?

So the job for this winter is to have the gearbox out, check the final drive, check what the car was ordered with from factory (if possible) set up to match tyres and, while we are at it, find out how much of the low-speed chatter coming from the transmission is simply a function of the raw, early homologation nature of the clutch (this was a problem that Porsche acknowledged when they added rubber to the plates in 1978, adding 30mm to the bell-housing to accommodate, moving the whole, 30kg heavier, engine back 3cm over the wheels and contributing to a deterioration in handling) and how much might be about wear. 4th whines like politician who has just lost a vote. That needs addressing, even though you have to be going crazy fast to need it!

Caveat - This is not first hand knowledge. I was 10 in 1975. All the info. above comes from books. If the books are wrong, so am I!

 

Body color would be correct but in the wheel wells it would be a black finish over the body color. This was done by the factory to give the flared fenders a sense of depth. Black cars did not need it.

Idart posted these pictures in post 6676 of a '75 turbo and a '76 turbo at the factory where you can clearly see the black finish in the fender wells.

As these cars are getting repainted and restored this is often times overlooked.

Phil, sent photos of my car to a UK Porsche expert. His opinion is that the "black" stuff in the wheel arches and overlaying the red paint is a dark brown wax that was sprayed onto the car at origin. May have been a Tectyl product but it has been there from day one. It is correct and over time wears away and takes on the black look you see now. The blobs on the floor pans are probably not original and would have been put there later. I will probably get those detailed out. The brown look on the trailing arms is a lighter factory protective coating. That stays.

 

There are a lot of knowledgeable early turbo folks on here and I'm hoping someone can help me.

I'm reassembling a non-intercooled 1976 911 Turbo Carrera wing. The car was originally optioned with a rear wiper that someone removed for some reason. I have some of the parts (motor, bracket, early wiper arm, blade) but not all.

Does anyone have:

#4 - 'Wiper Mounting Complete' It consists of the 6 bracketed parts
#7 - 'Linkage' This is the rod that goes from the motor to the linkage

I have complete assembly from a 3.3 intercooled turbo and the parts do not work on the 3.0. Porsche must have beefed up the mount rod as it will not fit through the hole in the wing.

If you have any of these parts (or the whole assembly) please let me know. Thanks!

Good luck

 

Mine has big reds not the later 930 style brakes. Car was a track rat when purchased and I am spending a ton of money to get car correct so big brakes gotta go ;(

Phil

 

Money well spent Phil! There are a lot of cars being brought back to like new. That's exciting! These cars deserve it...

 

I agree, been a labor of love, can't wait to get car back and beat the piss out of it.

 

I just purchased a factory turbo carrera work shop manual. Based on pictures in manual it would appear that the different years may have different surface finish in fenders wells. the picture Sloan posted clearly show a satin black finish with Cosmoline sprayed over that. I am thinking that the earlier car wheel wells had a different finish. This was Joe's original question- seem like we still do not have a definitive answer.
Phil

 

Phil,

My original 1977 has satin black in the wheel wells. I have 3 1976's and all three have or had satin in the wheel wells. That includes both Euro and US versions.

 

Phil,

This is a factory photo of a '75. You can see the black in the fender wells.

My 76 also has cosmoline / black in the wheel wells and the paint and car is original. I have also seen original cars without the black wheel wells. I don't know that there is a definitive answer to this one.

As for the underside, I have only seen it painted in similar colors to body paint, but with a more dull finish. I have yet to see an underside with just the grey finish.

 

Great data points- seems like materials and where exactly it was applied may have not be 100 % consistent.
Phil

 

I have a black 76 930.
It has exactly this type of black/gray'ish coating covering the entire bottom of the car including the wheel wells.
It is without a doubt the factory application.
It has a rubber-skin-like quality to it (my guess is it is a Würth product)
I have never seen an original 76 930 with any other type of factory underbody coating. And I have seen a few.
