The suspense was killing me; so working on the front brakes were pushed off and the car was weighed first. Left out of the total are several aluminum panels, which aren’t much, though the missing stainless firewall is probably 20 lbs easy. Then there’s the windscreen but heck, I’m happy. First picture is the setup, second is the weight of the car alone, with oil and coolant but no gas. Third is with me in the car – note how the weight distribution changed very little, due to the seat being near the CG. The rear weight bias is at the upper limit of what I wanted to see and it remains to be seen how steering will be under throttle; will it understeer like crazy or not?
A couple things are affecting the weights: two of the scales are half on the carpet that’s under the car so aren’t evenly loaded, and the garage floor is tipped toward the door by about 2 deg. It’s hard to say how much the final reading will differ, but I’m extremely happy with the weight! Use a slightly smaller normally-aspirated engine with smaller 15″ tires and racing wheels, and the dry weight could easily be in the 1300s. Don’t worry about the variations in corner weight; the spring seats haven’t be adjusted at all, it’s the weight total and weight distribution that’s important right now.
The power-to-weight ratio, which is always calculated without driver or gas (totally unrealistic, but it’s how it’s always done) and it works out to 3.6 lbs / hp. A real-world ratio is the car with driver and half a tank of gas, adding a bit more for parts left out, it works out to about 4 lbs / hp. That’ll do!
Also shown is the rear with (finally) all four taillights. Still don’t like the screen…
