Close to 145 in a 911 SC (with about 9 psi of boost).
Felt like a gazillion.

I went well over 120 mph in a 914 a few times, that was at around 7 psi boost. Felt like 2 gazillion.

I did 130 in a stink-bugged 69 GTX when I was 17, used the entire freeway. The Dumass (me) is lucky to be alive after that stunt. It did not handle well at that speed.

I did over 145 in a blown gas flatbottom drag boat. Darned near dropped a duece in my suit every time.

I've gone over 150 in drag cars many times over the years, most were set up decent so it wasn't that big of a deal.

It's all relative. If the car is designed to do it, it's not that big of a deal. If it's not designed or set up to do it, it'll scare the crapoutaya.
