A buddy of mine is the new owner of my 1975 US Carrera with bone stock 2.7MFI 8.5cr motor. A while back I had it dynoed at ~208hp to the rear wheels. The other day he did some 0-60 runs with my G-Tech, and the best run was a 5.07 sec blast. I am fairly certain that these G-Techs are somewhat accurate, so this confirms my thoughts that this car "gets it." The car is completely stock except that I yanked the AC. The car has the trans from my 911E, so has the 7:31 along with a factory LSD. Not sure what the car weighs, but I would guess in the 2300's.
Not too shabby for 30 year old technology.
Thought some might be interested.
This same friend is putting a 3.8varioram in a lightwt early 911, so a new 0-60 level with obviously be set with this car when it is completed in the next year.
