The very first thing to remember is that as senior citizens neither I nor the car have anything left to prove. As the current custodian of this car, I serve no purpose by blowing the motor or going off road into some unmovable object. The second consideration is that with all the trophy gathering of late, it has become rather valuable. I would characterize my driving at Road America in August as about 7/10. Remember it was a wet track, and the old brakes were cold, and the tires are skinny.
My sense is that the motor is as strong and responsive as it was when I raced it in the sixties. It retains the performance characteristic of very little punch under about 3700 rpm when the cams "come on". The cam timing for the day was quite radical with open duration for intake
of 310° and exhaust of 306°, an exhaust/intake overlap period of 98°. Clearly a design for horsepower at higher revs. It is also a prescription for embarrassing stalls when attempting to get away from a stop. I recall quite clearly the first time I drove the car at a SCCA Drivers School at Cotati. On the back side of the course was a 180 degree turn. I entered it in too high a gear and about half way through the turn I spun out. It felt as though someone had hit me from behind, but when I looked around there was no one close. When the motor came on the cam it simply broke the rear end loose and away we went.
The power/weight ratio is somewhere between 9:1 to 10:1 which gives respectable get up and go. (172 bhp at 7000 and dry weight of 1584 pounds) The current final drive ratio is 4.54:1 which gives me about 126 mph at 7000 rpm. On that long uphill straight at Road America I was reaching a hair over 6000 in fifth which translates roughly to about 110 before I had to start my early early braking for turn one. Heavy throttle leaving turn 14 led to some fishtailing a couple of times but nothing worrisome.
Regarding sway, I have never been particularly conscious of sway in the car. There are many exciting sensory events occurring when you start to push it but lean or sway are not ones I recall. The car was one of the first with coil front spring independent suspension (previous cars had a transverse leaf suspension), and the tried and proven DeDion rear suspension provides a fairly balanced and nicely handling car. It clearly comes from a time when one needed to ensure your entry speed was slowed by the time you hit the apex.
By the way the car on the track at RA was the first time in fifty years it had been back to that track.
