Anyone knows if replacing the standard rubber spoiler on 90 944 Turbo S with a 968 type spoiler what happens to cd drag figure - which one is more efficient as down force goes? You see I think the 968 spoiler has been designed rather for looks than efficiency?

In Canada the 1990 944 Turbos have the 968 type rear wing (basket handle.

They do look great, are easy to keep clean, no need for black polish.

As to efficiency, Porsche states " The new rear spoiler reduces rear end lift" and "Finally, the 944 Turbo is equipped with a new rear spoiler designed to reduce lift and therefore increase adhesion." ( 1990 Porsche sales brochures (Canada & UK)including pictures )

There is two surfaces for wind to pass over as well as the lip under the wing.

Do not know the coeffcient but the cars drag coeffecient is 0.33

SK</strong><hr></blockquote>Isn't it incorrect to call a 1990 944 Turbo a "Turbo S?" I thought all turbos produced after 1988 were just turbos, even the 1990 and 1991 models for the ROW.

That said, I'm in the process of changing my rear 944 hatch to a 968 version. If you are contemplating this the only practical way to do it is by getting a complete 968 hatch from a donor car. It's too much trouble, work, and expense to try and convert a standard 944 hatch because the individual pieces are very expensive.

I don't have any information on efficiency, but just by looking at the 968 version I'd say it's better because you have a true airfoil, not a spoiler.

The Canadian 1990 944 Turbos had no "S". The 1988 was the last "S" here.

The 1990 had few options available as it came with close to everything including wider rims up front.

The rear wing (basket handle), spoiler is 7 inches wide and the lip on the glas is 2.5 inches wide. The rear brake light is still at the top of the glass inside not under the spoiler as the 968s.

Oh and Hi Tom, your car looks great with the 968 door handles and mirror up grades. Are you going to Boise?

Hm, interesting point you make about my S fix. In the UK 944 turbos after 1988 were all called S. Silver Rose which is an 88 model was called SE. Before 88 they were just turbos.

Funny Porsche people ej?

No, only the 88 was the Turbo S. The Porsche S tradition has always been to offer a limited production run of cars with the next generation components. When these become standard, they are no longer S.

SimonK

Look... Porsche is an European car right? I am telling you all out there the way worked here in the UK - 1988 was called SE - special edition - Silver Rose)! Anything after then was called S. Anything before was just Turbo. Also, factory model designation for 88 and beyond is 952 and before 951.

That's the way it is on this side of the ocean. What happened to designations in USA is anybody's guess.

Do you really think Porsche would change the designation # just because it is on one side of the atlantic? Hmm, i don't think so, or we would have a part out there with a part # of 952-xxx-xxx-xx and I'd like to see it. The changes from the 944 and turbo were sustantial enough to warrant the new # 951. As for the SE part. I've heard of this but don't know about your passion in calling your car turbo S so I have no comment.

SimonK

Well, they changed your bumpers and repeaters...

Here in the US: we had both a "Turbo" and a "Turbo S" in 1988. The first set of the "Turbo S" cars were the Silver Rose, and only a few (1000?) were imported. Sales were so good that they started offering the same '88 car in other colors. In 1989 the original "Turbo" was dicontinued, and they only made the turbo's with the "Turbo S" trim and equipment. Since it was the only turbo 944 they offered that year, the S designation was dropped and simply called the "Turbo". Original "Turbo"s are referred to as a 951. The "Turbo S" I have heard referred to as both 951 S and 952 (applicable to the '89 model as well).

Hi guys, girls?..

Canada was lucky in some sense, We are not ROW ( rest of the world) but did have US equipment on some of our cars. The 1990 944 turbo was not inported by the Fadtory / dealers in 1990 to the US, Canada got 40 of the 47 made. Mine has the OBD required label but the car was never to be sent to California?.

Options were full with few extras available? Is it a S ? well it has larger rims than the 88 S and 89 ? , HP is listed 3hp highter??? via Porsche but it does not have the front Koni shocks, as this was an $200.00 option but the sway bars were upgraded?

I have been to the UK and seen some weird designations not in North America or the Rest of the World. My UK 1990 944 Turbo brochure has an option listed as no Cat? figure that in the US ?

Any way,

We continue to fill our heads with factory stuff.

Sorry for all the spelling mistakes,

Just got back from the Brier? Beer fest , Curling National fest.


I can not tell you how many guys put the "S" on their car in 89 to show they had the up grades.

No S in 89 , 90 , 91 in Europe I know of but the cars had the upgrades..

Now, Lets all go for a beer !!!!

Okay, I am in trouble again..
