Snygga sidepipes

Riktigt FET! Men varför bygger man om en A6:a när det finns A4:or?? I mitt tycke är nya A4:an riktigt snygg!

Kanske ett riktigt långskott, men jag tror att det handlar om racing och inte styling. Reglementet tillåter antagligen inte motorbyte.

Erik: Hur många hästar har skakat fram ur dessa motorer i raceskick?

En trolig anledning kan också vara marknadsföring...

De ligger på c:a 470-480 hk mot 450 original. Det är ett strikt reglemente som talar om vilka mods man får göra.

Tydligen var RS6:orna snabbast ut ur och i rakorna, men höll upp folk i kurvorna - ungefär som motorcyklar.

I år kör S60R i samma race...

Måste vara väldigt strikt. Det är ju knappt chiptrimmat. Annat luftfilter och lite coola sponsordekaler så har man ju 20-30hk extra.

Nära 500 hk är ju snuskigt mycket effekt oavsett hur mycket det är vässat på maskinen..

Hur pass får man modifiera chassit? Det ser ju ut att vara väldigt bred spårvidd jämfört med original om man tittar på bilderna.

om man får ned vikten på bilen (den är väl ohyggligt tung i standardskick om jag inte kommer ihåg fel) och får modifiera fritt i chassiväg, då borde det gå undan på banan..

Mer fakta:

"The first round of the 2004 SPEED GT World Challenge is held on Friday as part of the Sebring 12 Hour race support programme. Title holder Champion Racing goes to the grid under the new entry of "Audi Certified Champion RS 6 Team". The outfit of the Audi RS 6 Competition, re-worked technically in many details, is also new: The defending SPEED GT champion Randy Pobst and his team colleague Michael Galati now line up with silver and red cars. The two Audi A4 STCC cars of Team KMS Motorsport that race this season in the Swedish Touring Car Championship (STCC) will be painted in a similar colour scheme."

Mao blir det liknande STCC-bilar, fast A4.

REGLERNA
SPEED GT - the rules

The Sports Car Club of America (SCCA) organises the SPEED World Challenge that consists of two separate race series for touring cars and production car similar GT cars. Champion Racing competes in the GT class with the Audi RS6.

The key elements of the SPEED GT regulations:

Cars: The SPEED World Challenge GT cars are based on production models that may be modified for racing. A datasheet detailing all modifications and components allowed is issued by the SCCA for every car. Only cars built between 1997 and 2003 are permitted.

Engines: Normally aspirated or turbo engines based on the production car versions. Minor modifications compared to the series engine are allowed.
Tyres: A maximum diameter of 18 inches, one make tyre from Toyo. A minimum of three of the four tyres used in qualifying must also be used in the race. The quantity of rain tyres is free.

Weight: A minimum weight for every car is determined by the SCCA.

Handicap system: Handicap regulations are valid for cars registered for the manufacturers' championship: The first three cars in every race receive additional weight. In addition, the SCCA reserves the right to adapt the basic weight and tyre width to guarantee parity of equipment.

Schedule: Every SPEED World Challenge event is comprised of practice, qualifying and race.

Speed limit in the pit lane: 45 mph.

Qualifying: A qualifying session at every race decides the starting grid. Refuelling during qualifying is prohibited.

Start: Standing start.

Race duration: A maximum of 50 minutes.

Drivers' championship: At every race, points are awarded to the first 25 finishers as follows, 30-27-25-23-21-20-19-18-17-16-15-14-13-12-11-10-9-8-7-6-5-4-3-2-1. Bonus points are awarded to the fastest five drivers in qualifying, the fastest driver in practice, for every driver who led a lap and for the driver who led the most laps during the race. No scores are dropped; in the event of a tie at the end of the season, the best single results determine the winner.

Manufacturers' championship: The best-placed car of every registered manufacturer is classified. Points are awarded for the best six position as follows, 9-7-5-3-2-1.

Haha, KMS har väl inte bekräftat att de kommer till start än?

LYFTER denna gamla tråd,
då jag precis fick se en film från ett race med dessa två RS6:or och sökte mer info om bilarna så hittade jag denna tråd med info här på rejsa

Men ni har missat film i tråden så här kommer ett häftigt race:




Synd att den är nerkortad, skulle vilja sätt vad som hände i mitten av racet..

Någon som vet vad som hände med dessa bilar sen?


Här en kort film där ena föraren pratar samtidigt:
