discovered the solid argument for SC's as far as performance goes. The G-50 transmission was a solid improvement over the 915 but at the cost of about 100lbs of weight which would equal about 2-3% reduction in power to weight ratio.
Have to say I lucked out with my car. It is a 77 911 S with a 82 sc motor with larger pistons and cylinders with 3.2 liters. The car below 3,000 is fun to drive but nothing really overly exciting but start flogging it over 3,000 k like you have gone temporally insane and the car is a screaming beast. Once you get it to redline in first the engine stays in the meat of the engine like a switch has been thrown and never really comes down. Each shift of the gear you find the engine going 3k rpm after hitting redline.
The car also feels light and nimble like my old 1969 E but with a much more robust engine. The steering is more accurate and the suspension is better than my 2009 335I, the only time you feel the weight of the steering is under 5 mph. At speed the car is planted and with a quick drama free flick you can be in another lane if you like, snap your fingers quick.
And my AC works amazingly well in all kinds of heat, after I completed my garage floor mod on it
