Zero.  Lifetime. 

If everything seems under control, you're just not going fast enough. - Mario Andretti

well, you're certainly not past the vehicle's limit

maybe right there, but.........

Exactly.  If you take a car to its top speed, that’s a limit.  If you corner it to the point it swings out either the front or back end, that’s at or past the limit.  If you brake from 100 mph to measure the braking distance- that’s the limit.  If you launch it repeatedly from a standstill until you have maxed out the 0-60 or 1/4 mile time, that’s the limit.

if you use your cars lap timer and hit a curvy road, time it, and push the car until you can’t improve the time, all with traction control turned all the way off, that’s the limit. 

you know quickly what the cars limits are. 

So, for example, the BMW M440i I just got for my wife, has already been tested for 0-60 and 1/4 mile, as well as top speed.  And - tested in different DAs ( density altitude - which has a major impact on a vehicle’s performance - especially a forced induction car).

Now we are going to get it tuned with a high flow downpipe.  That should add roughly 100 WHP and WTQ.  Then we will run it again see what gains are had in real driving.    I will post a video   

Haven't pushed it near limits on the curves— YET.

We take our Jeep offroading fairly frequently.  I'm not sure we're exploring the limits of the car, but I've definitely explored my limits as a driver.  The vehicle is far more capable than I am.

I miss my Jeep so much.

Every clean truck/jeep is a tragedy.  USE THEM!  Otherwise, get a go-cart, lol.

I used to do all of that. I don't even take my current car to its limit, mostly due to how people drive around here, to be honest.

I've had

Cutlass with a 455
Formula with a 400
Regal T-Type 231 turbo (couldn't afford a Grand National, or even find one)
Porsche 944 Turbo 2.5L turbo
Porsche 928 S (don't remember the power)
Volvo 850 turbo (don't remember the power - inline 5)
M-B E350 AMG enhanced - 3.5L (current car)

I've maxed them all except the latest. I suspect it would top out around 150 or so?? Don't know.

The Porsche 944 Turbo was the fastest of all of the above. I had her up to 160 on I-90.

Since 1997 I'd had exactly two cars. Heh.

I was curious and gonna ask if you were at the track or not but didn't know if you wanted to reveal the answer

The tracks here are too crowded. I used to go to Milan or Lapeer and get 5-7 runs in, during a 2 hour visit.    

At the track here in Florida ( Palm Beach- now closed anyway ) you could wait 3 hours just for one pass down the track.  No thanks.  The one good thing about going to the track is they put the sticky glue around the start area so you get a much better launch because your tires stick

never had a car on a track or the strip
tried the dragstrip a few times on bikes back in my 20s

don't feel it needed with a bone stock C8
if I was doing mods looking for more and more performance it would be a good gauge 

did a few seasons of 2-wheel dr pickup pulling back in my 20s - pullin wheelies with a pickup is good clean fun
