Details on the RUF SCR?

[rdane]

Anyone have more info on these cars?

This is the majority I have pulled off the Internet.

I have the original salescontract from Pfaffenhausen (for a '76 car done in '86 ). It says the car has a RUF-Motor SCR made from a 200HP Carrera engine, Ruf short shifter-transmission and dual exhaust...

(anyone care to translate)

This translated from a German wed site:
http://translate.google.com/translate?hl=en&sl=pt&u=http://www.mundoporsche.hpg.ig.com.br/911src.htm&prev=/search%3Fq%3Druf%2B911%2Bscr%26start%3D10%26hl%3De n%26lr%3D%26sa%3DN

The necessity to reduce the fuel consumption and if to adapt the new laws of emissions of pollutants in the end of the decade of 70 forced the Porsche to reduce the power of its cars. Inhaled 911SC 3,0 was with only 180 horses, the Turbo was vendido aside remark, this opened an opening in the scale of models while the customers who had desired more harness would have that to go for comfortable the 928.

The RUF then extended the piston displacement and retrabalhou some parts of the engine of the 911 SC, what rpm resulted in a the 6000 power of 215hp, what resulted more in 35hp than of manufactures. The manual transmission of five marches of the RUF still contributed for a good set and a good fuel consumption. The performance of the SCR(como was called after) was very similar to the one of the Turbo and if it incases perfectly in the vacant left for the Turbo at the time of the crisis of the oil.

Introduced in 1978 together one to the RUF Turbo 3,3, the SCR was plus one of the possibilities to optimize the Porsche engines.

Then I found this which has a entire list of goodies available for the SCR .

Anyone have more details on this early RUF car they would like to share?nyone

I believe the SC Ruf cars pre-dated what the Porsche factory did when they went from 3.0 to 3.2 liters.

RUF essentially went to a 3.2 liter displacement ( can't recall if it was closer to the 98mm/short stroke combo...likely...or the long stroke that the factory ultimately went with).

These early cars put Ruf "on the map" long before he went to modify Porsche's turbos....as I recall.

Thanks Will. I had thought Ruf was doing the 3.2 short stroke aka Max Moritz 98s as Bruce Anderson mentions in his book. Looks like he started offering the SCR conversion in '78. The date on the converison mentioned above (info from the engine building forum) was done in 1986 and would have the light Carrera 3.0 crank I would think making it a 3.2 short stroke.

Does anyone else have info about the Ruf SCR?

Ruf used to have some information on their web site. Thanks to the Wayback Machine we get this:

911 SCR



The need to reduce fuel consumption along with stricter emission laws had become one of the automotive industry´s most urgent issues in the 1970s. To adapt to these new standards, Porsche reduced its normally aspirated 3.0 litre flat six to 180 hp. Apart from the expensive Turbo, this opened a gap in the model range as customers who desired more power now had to go for the comfortable 928.

Consequently, the 911 SCR conversion´s centerpiece is the SC engine enlarged to 3,185 cm³ with a peak power of 215 bhp at 6,000 rpm. The RUF five-speed manual transmission contributes to significantly improved fuel efficiency. Along with better tractability, the SCR´s road performance nearly matches the Turbo and perfectly closes the gap Porsche left open for political reasons.

Introduced in 1978, the 911 SCR, together with the RUF Turbo 3.3, completed Ruf´s model range of optimized conversions of both the Carrera and Turbo.
