ALB posted:When fully warmed up, how high does the engine go with power when accelerating in 3rd gear?
On the street, I have never paid attention at what RPM the engine stops making power in third gear - I'm not sure if I trust the Chinese or Brazilian tachometer on the Vintage because the movement is not smooth. I'll make note the next time I'm on a spirited drive and will report back. Going by memory, when the engine was on the chassis dyno, it made HP power to 5700 RPM (max 128 HP at 5400 RPM), but I'm shifting around 4800 RPM because the torque is down low. I can break the tires loose when I shift into 3rd gear with a passenger. There is only 20 ft. lbs of torque difference between 2300 - 5400 RPM and max torque was 138 ft. lbs. All numbers at the wheels. The curves are very flat. But the torque curve has definitely shifted to the left 
I can feel the acceleration slow around 5K in 1st and 2nd hence I shift at 4800 RPM when driving spirtedly. In the city, I can shift between 2200 - 2400 RPMs and still be able to keep up with traffic.
ALB posted:And I know the oe Lemmerz wheels are heavy, but at 20 lbs each axle that's 40 lbs, right?
Yes, I meant 40 lbs total. One 6x15 Deep Six Fuch with a 185/70 Pirelli Cinturato CN36 tire weighs approx 21 lbs. The steel Lemmerz weighed the same but with no tire. I mounted a larger and inexpensive 195/65 tires on the steelies at an approx which weigh approx 20 lbs.
