When C5 was introduced in 1997, GM claimed the stock car had a top speed of 175 MPH.

Has anybody here reached the top speed or his or her C5?

Of course, on a road that has no speed limit. We would never exceed it

I believe Montana has no speed limit at certain places.

I have heard the same, but have not verified that myself!

I've had mine up to mid 180s and pretty sure it would do over 200 if I had the room, not stock though... I might be wrong but I thought they were speed regulated from the factory and you can remove the speed limiter in the tune

There are a couple of races like the Mojave Mile and one on a runway in Texas where Vettes and other cars go very fast. Look them up!

Z06Berlin

I lived in Berlin back in 2003 and had a 2003 Z06 and would run it wide open on the autobahn (where allowed), I had it up to 165mph and backed off as I could feel the car lifting (started a close to 160). It was fun driving on the autobahn as the Germans thought that my vette was what they had there (coup and convertible) and soon found out it wasn't. My car was stock, never modified.

163 got scared an backed down

No, it was "drag limited" at that speed. The C6 was a bit faster - more power, and different 6th gearing.

OTT, but years ago I read the late Duncan Hamilton's book including descriptions of competing at Le Mans in the Jaguar "D" type. In the wet, at full speed he reported wheel spin as the rear end had lightened dramatically. As the D would hit 180, he was definitely a ballsy guy.

interesting... there is a speed limiter table in the tune though but I have no idea what a stock car is set at

92 and wife told me to slow down. We're old.

No desire for that stuff, you have 0 control at that speed; if something happens youre along for the ride.

0-120ish sure. When youre approaching 160, you get a good side gust, a coyote runs out in front of you reality sinks in quick.

I've had my 98 (905HP) up to 165 mph very quickly. I've had my 02 (damn near stock) up to 167 mph and like Z06BERLIN said, the front end started lifting and I felt very uneasy.
As far as a speed limiter, it might be true for an automatic but I'm pretty sure the manuals don't have one. The top speed is in 5th gear and is rev limited. In 6th gear, drag takes over horsepower. That's why I still wonder today what the top speed would have been in my 98 as I believe she had enough horsepower to over come the drag in 6th gear.

I have heard the same from many people but I have never experienced it in my car, do you have any idea what the cause is and what can be done to cure it?... I have read that pressure builds up in the engine bay which lifts the front end and a vented hood will let this pressure out to keep the front end down which makes total sense but I still have a stock hood lol... my car is lowered on coilovers and I have sway bars, that's about all that's really done to the suspension that I think could make any difference... I ran 171 in the half mile (and was probably doing 180 when I let out) a couple of months ago and it felt very stable at that speed and drove straight

Lingenfelter twin turbo C5. 226 mph at the TRC in Ohio. No mention of lift issues.

I had mine up to 179 but the shifter hung up between second and third.

Yep... I've had this exact same kit on my Z06 for 14 years. I haven't had it _that_ high, but have little doubt it would do that speed.

CQRT

I thought they were electronically limited at about 165 . . … between my C5s and C6's, I really havened pushed it much past 125 . . .

Nope, for a manual at least.
