What?!!
I don't think my car can do more than 170 km/h and I don't suppose there is any rev limiter !!!

It has a centrifugal spring limiter in the rotor which is located in the distributor.
Depend on the spring limiter, it cut off at 6.400rpm-6.600rpm

In a rotor whitout limiter, you could get to 7000rpm (if not damaged the engine)
but real speed is 175km/h (4gear or 5gear direct)

you're right for centrifugal spring limiter :mrgreen:

back then, 1.6 engine had carb from bmw 2002 with 4 speed gearbox and rev counter for 6cyl engine (readings must be multiplyed with 1,5 for true readings). tyres was 195/50/15
rev counter showed 5000rpm and vibrations from engine was so intensive I had feeling something would start falling of the car

i do not belive to speedometer because it was bouncing from 190 to behind 200kmh mark
speed calculator said that at 7500rpm in 4th gear (1.000) with 4.1 final gear ratio and 195/50/15 tyres speed was 199kmh
Understeer is when you hit the wall with the front of the car. Oversteer is when you hit the wall with the rear of the car.
Horsepower is how fast you hit the wall. Torque is how far you take the wall with you.

Well, my speedo is better than accurate at the moment!
It does not bounce (only a bit of bouncing at low speeds) and it shows some km/h LESS than what the GPS is counting!!!
(for example, when it shows 100km/h, gps says 103...So I guess that when I see 165, the gps speed should be around 170??)
