Does anyone know the exact set up for the CTR? A friend who had one said they ran stinking rich to cope with all the boost and heat, so they could cope with mile upon mile of Autobahn abuse.
Thought maybe their system might now be easy to replicate?

"For the CTR Ruf uses his own intake manifold similar in design to the Carrera manifold, but larger in capacity with the special Digital Motronic Electronic (DME) fuel injection and ignition system that was originally developed for the Porsche 962 race cars used to control the fuel mixture and ignition timing. Instead of measuring the air flow like most electronic engine management systems do this system is a pressure sensing type system which uses throttle position, rpm, engine temperature and manifold pressure as input signals. This was the first of these high powered 911 turbo engines that really ran right and made a lot of horsepower"
