Getting past 145 mph is difficult as I see from others who tried. There comes a point at which there seems to be an end of the fulminating acceleration and any gain in speed is dependent on aerodynamics.
Anyway, after that trip out to test top speed something has given, because my 427 SO is burning lots of
oil, as the sidepipes tell. I must check the headgasket, maybe it has got a leak.
With a Lambo you probably hit over 180mph with ease, but the Cobra gets to the 140mph mark so fast and with so little drama that makes you feel at the helm of the most powerfull machine on earth. I would not worry about what happens beyond 145mph, which is a not legal speed anywhere bar German Autobahns.
The brutal acceleration and 145mph is enough for me.
