Who's car is this?

Mike,

In the early 70's spoilers were controversial. In the Carrera RS book there is graphic that shows results of testing done by a German automotive magazine Sport-Auto to test the speed and handling of the RS in a number of combinations without and with the front and rear spoilers. Compared against a base line of no spoilers, just a rear spoiler gave a .5 KPH advantage, but made the handling quite poor, with just a front spoiler the advantage was 2.0 KPH, and with both front and rear spoilers it was an advantage of 5.0 KPH and the handling was far superior. They concluded that indeed Porsche was right in their claim of markedly improved top speed and handling.

Don,
I thought you already had a rust free 'T'. I know its white, but if you put the rear RS flares on you could then paint it red. Don't you need another project anyway?

I was at Ruff's exactly two years ago this month. He spent a couple hours with me showing me some cool stuff. That red car was there just sitting and he said it belonged to a customer and it wasn't for sale. (of course I had to ask!) Jens, do you know where that photo was taken?
Speaking of red with no spoilers, wait until Herr Schmidt rolls out his R Gruppe project next year! Jeff is a little sheepish when it comes to his body work, but his work is as good as it gets, believe me! I will attach a photo or two, but the only rear shot has the deck lid up. I saw it down, unbelievable.
he may not be happy with me posting pics of the project, but I am sure he will heal over time!

Jeff is into correct detail, note the seat sliders.

Rick, this was at RUF in Pfaffenhausen.

Did Schmidt go as far as to putting tar on the floorpan prior to painting?

Thanks for the stuff on handling and spoilers. I feel that my Targa "lifts" the front when I'm going 90 or over - no vibration whatsoever though. Not sure though if a Targa is the best car to test out handling questions

I guess this "take off" feeling is what was supposed to be stabilized primarily with the spoilers (apart from the speed gain)?

[Jens]

Yeah Mike, the spoilers reduce aerodynamic lift by keeping less air from getting under the front of the car and by "spoiling" the laminar airflow over the body. The early 911 was by accident a real good approximation of an airplane wing that makes the car lighter at speed and want to fly or lift off. Not good for control.

The IROC "tea tray" wings were designed more to apply downforce to counter-act lift (not just spoil it) giving much enhanced cornering and braking performance. The modern F-1 cars produce as much as 4000 pounds of downforce at speed on a 1400 pound car. It is said that at only 100 mph they could literally drive upside down in a tunnel stuck to the ceiling. I want to see that done!

However, every once in awhile I'll look at my stock deck lid and think... maybe I should put it back on for awhile.

I've toyed with the idea of installing spoilers along with the rest of the car's track equipment, but keeping it stock all other times. My guess is swapping the engine lid is easy, but the front spoiler would be a pain. Someone should develop a removable chin spoiler for the early cars.

OK guys educate me here: Is this an RS without the ducktail?

Now I know that the ducktail was actually an option, I just have not seen a pic of one without before.

Wow, I think it looks even better without - awesome car.

Hi Mike,
Ferry Porsche clearly had a taste for the outrageous.
No duck tail, body coloured headlight rings, wheels and bumper guards. Round mirror, black anodised window trim, hand painted Carrera script and blue pig skin high back seats. The colour is pearlescent metallic pale green.

The duck tail reduced rear-end lift at 152mph from 145kg to just 42kg. At that speed, crosswind stability is significantly improved, rear wheel grip increases by no less than 20%, and the aerodynamic front/rear lift ratio is almost exactly aligned with the car's weight distribution [45% front/55%rear] And these benifits can be experienced at far lower speed too.

If you want to have the aero advantage of a ducktail but without sacrificing the original silhouette, a 964 lid is a good alternative.
