this is great, i was wondering about the exact same thing out on the autobahn yesterday.
the '40 has 201cui/ 3speed dry clutch and, if i measured correctly, a 4.22:1 rear end. wheels are 16" with 6.00x16" silvertowns.
i'm going 65 without a problem, cruise speed is 55-60 miles.
there's more to come above the 65mph mark, but i want to install a tachometer first and change to SAE 50 oil,
since the oil pressure is dropping when the engine tempgets past 180F.
then i'll know where i am and can try to go faster.
i was really impressed how well these cars handle, the ifs and telescope shocks work great,
so does the 3speed, and with the 6.00 bias plys the steering powers are really low and the car is very agile in city traffic.
back to topic:)
i couldn't open the link, it says "video not available in your country",
so i guess it's some kind of music video?
