90 mph. I do not know how you guys do it. I hit 90 and the recurrent thought is "How did those SOB's RACE this car, weekend in and weekend out?" You'd have to have a death wish.
Admittedly, I do not have the balls. Not in a Cobra, anyways (I drove my C5 Corvette at 130 a few times, then limited by the thought of my wife getting me out of jail
)
