I'm too wussy to push any of my rides all the way out.
Neither 2 wheel or 4 wheel.
I correspond on the GTO forum, there's a guy who regularly posts street race videos,
to test your pucker factor, you might watch his clip filming a bike race between two demons, a turbo hyabusa and a prepped gsx1000
In discussions about the race, the GTO driver says
...if you look closely when the camera pans over my speedo needle is indicating 180mph but it was already slowing down.
This 6 liter GTO has dyno sheets showing 800 hp and runs top end races every week. I've seen several clips of him above 185.

the second clip is an old one, shows how quickly he can jump up by 100mph, starting at 70...

I've got the same car, and even the same twin turbo kit to install,
but way lacking the stones.
