Until a few weeks ago the fastest I had ever driven was 130 in my 81 Z when we took a road trip to TJ from IL ... with a detour for the Bonneville salt flats on the way home. I was 18 at the time and my rear end didn't unclench until I turned 19.
Like 170bcuda, there was floating, violently fluttering wipers, and rocks for tires. Unlike 170bcuda I didn't have anymore pedal and my window trim remained intact .... my wipers and passenger side wiper arm not so much.
Then a few weeks ago I hooked up with a guy north of Chicago to get some input on a 6 speed auto from TCI and we took his Yenko mod clone out for a spin. Then we took his supercharged C5 out ... I didn't drive, but we hit 155 for about 4 consecutive miles on a completely open 90/94 going into IN. I'm still clenching I think.
