Porsche 993 Supercup car
Hi everyone,
I have several stupid questions. What is the chassis type of a Porsche 993 Supercup car? Is it a wide body or a narrow body? What are the dymentions for wide body and narrow body 993? <img src="confused.gif" border="0">

Since we're looking at the details of the 993 Cup car, anyone know what's different about the fuel tank? Say, compared to a regular 993, what makes the Cup car's fuel tank different, from a safety standpoint?

Mav,
They are based on a narrow bodied car.
DJ,
I would guess they have a fuel cell from the factory with 100L capacity. That is what I have seen in the 993 and 964 Cup Cars.

Hey Greg,
A real fuel cell (aluminum box type)? Hmm... I heard that it was just like the stock 993 fuel tank. Maybe I'm thinking of the 996 Cup?

DJ,
It could be that the ones I looked at were retrofitted with a fuel cell, I would think they would have a true fuel cell from the factory considering how they were used. Maybe Steve W can give us a better answer.

Greg, Mav and all:
The 993 Supercup is a narrow body car built on the stock 993 chassis. It has a plastic fuel tank just like the street car, albeit at a different capacity. Additionally, the 996 GT3-Cup also has a standard fuel tank, although it is installed from the bottom of the car and surrounded by a metal box. This may be just like the street car, but as I don't have one, I don't know how the street car is set up.

Hi JM
Having a supercup in the garage must be great. May I see the photo of your supercup? May I have the engine spec? What are the spce of the tires.
Thanks <img src="graemlins/yltype.gif" border="0" alt="[typing]" />

For the picture, look in the classifieds, it's blue and red. The engine is a 3.8l and develops 315HP and a about equal torque to a 996 cup engine.
The tires are Pirelli slicks 245/545/18 FR and 285/645/18 RR
When reading slicks dimensions, the rules are different than street tires. 285 means about 285mm of width, the 645mm stands for the overall diameter and the 18 is the rim size.
Hope this helps

Found this on the web: I have NOT read it but figured it may help you.

In the late eighties, Porsche developped an internal promotion based on a serie of races with the same car for each driver. It was called the 944 Cup and today, the 911replaced the 944 turbo. On the base of the new 911 type 993, Porsche developped the Cup 3.8.
The Cup is an evolution of the 993 RS CS, itself based on the 993 RS 3.8. Indeed, the Cup 3.8 has the same look than the RS CS with the GT2 style rear spoiler, side plastic protection, new three parts front spoiler featuring two lips and larger wings than the basis 993.
Nevertheless, differences are very important with the other models : the Cup has been designed for racing. 200 kg lighter, tubular body-arch for more protection and rigidity, liberated exhaust system (nevertheless, a catalysor is always present), racing tyres... The Cup is a racing car with all the preparation and the settings it requires.
Suspensions have been optimized while they are developed from the basis 993 and a lot of settings are available. The Cup also receives limited slip differential with 40% locking factor under acceleration and 65% under deceleration. Well, there's no place for hazard, just for racing efficiency.
The link between RS, RS CS and Cup is clear. That's the same body and the same engine. But the Cup 3.8 engine received some modifications to be a racing engine. The compression ratio raised up to 11.5:1 (a very high value allowed by a new anti clanking regulation ), twin spark ignition and a improved electronic control (Bosch Motronic M2.10). The exhaust system features two lambda sensor controlled catalytic converters. Unlike on the 993 RS engine, the Cup isn't equiped with Varioram system; as a result , the Cup isn't as performant as a 993 RS in retaking despite its light weight. With Superplus 98 fuel, Stuttgart annouced 310 hp @ 6200 rpm and a great torque of 370 Nm @ 5500 rpm; contact breaker operating at 6900 rpm.
The cockipt of the Cup 3.8 is functional : one single Recaro bucket seat with harness, three branches Momo handwheel, 4kg fire extinguisher on the right, no soundproofing elements, no carpets but door garnishing and instrument panel are conserved : maybe more weight could have been won.
The 6 gear speed box is very easy to use and like on the RS, there's no power steering. When you have a look on the external driving mirrors, you realize that the aileron is very present but it is not very ankward for rear visibility on the sides. Brakes are from turbo 3.6 with new pistons and brake calipers. With electro-hydraulic power assistance, the system keeps progressive and flexible. The last ABS standard make sure that the wheels can't lock but Porsche engineers said that condition to burst in the brake pedal lvery hard, wheels can be locked. The Speedline rims are looking like the RS one, but these three-piece light alloy wheels have a central locking system. With 8.5Jx18 front and 10J18 rear, the Cup receive 245 tyres front and 285 rear.
The behaviour od the Cup 3.8 is real excitement. You can only estimate it on circuit because the road isn't certified for road usage, as the 993 RS CS. The Cup behaviour is as much wild as the 993 turbo one is easy to understand. Indeed, beyond the awkward layout on the engine, Porsche engineers manage a real feat of skill with the 993 turbo : the excellent chassis combined with large tyres, integral transmission and engine flexibility have made this car one of the best handling one with a great facility. On the contrary, the Cup, which is a true rear wheel drive, despite optimized suspensions, is representative of the old 911 behaviour : the nose is very light compared to the rear that gives a big tendency to understeer at the entrance of a corner and to oversteer when removing your foot from the accelerator. The driver has to be very experienced because at the first hesitation, the race is finished !
The Cup 3.8 is engaged in the Carrera Cup : a internal championship with one type of car : the 993 Cup 3.8. In some countries ( like France or Germany ), there's an national Carrera Cup. But the best races come with the international Carrera Cup, where races are in prelude of Formula One championship on the best circuits in the worls. To promote this philosophy and to avoid any cheating, the factory deliver the Motronic electric control sytems after a balloting before each race. Of course, Motronic are the same and unmodifiable. The only settings are the choice of slick or rain tyres and geometry modifications.

Hi JM,
Thanks for your info!! A lot of info!! Do you know where can I find supercup speedline rims? Are they lighter than the RS ones?
BTW anybody know where can I get video tapes of European supercup racing around 1994 to 1997?

If you want the Supercup Speedlines for your street car, look at Gert's web site: <a href="http://www.carnewal.com" target="_blank">www.carnewal.com</a> This is where I got mine. There is an online bookstore in England <a href="http://www.chaters.com" target="_blank">www.chaters.com</a> I don't know if they sell movies, but they do sell books dedicated to Porsche Racing. They are titled Porsche Sport '94 or Porsche Sport '95, etc. I have several of them and they do a good job of photo documenting the season and cars not only in Supercup, but also in all venues where Porsches race.
Hank
PS. If you are looking for center lock Speedlines such as those found on a Cup car, Gert can probably help with that as well. You can also purchase them from Porsche Motorsport here in the US.
