Anyone test top speed safely in controlled environment?

I will say that above 150 MPH things get a bit weird. The eye is trained to process at 18MPH (max).
at 150 mph you are moving 220ft/s
at 17 mph = 249.3 ft/s
at 200 mph = 293.3 ft/s

Good luck and let me know what you find out on where to test, I'm curious.

Texas mile is probably the closest. Maybe an airstrip private rental event.

My experience with the 150 mile an hour statement you made is correct.
Simply put; it’s a different world above 150 mph.

Also, don’t forget; you also need better brakes… Lol

The next Texas Mile is October 28-30, I'll check it out and see if it's possible.

The stock V3 brakes were used when Cadillac verified the car goes 200mph. Plus there are only pad upgrades for V3s, rotors are factory only. Did you have something different in mind?

DOT 4 fluid and SS brake lines all around, PFC pads 08 compound if they make them for the V.

When I tracked my wagon the stock brakes were gone after 2 laps. Went to the floor in T1 at Palmer with x3 students in the car. I almost shit myself.

Upgrading the brakes is a must in my book.

There was an event, like the Texas mile, they do/did in Florida. I'd like to do it too.

thanks that's really helpful and I'll plan for that if I do it. But considering what I've just spent on recent upgrades I'll most likely have to wait until next year. Maybe we can plan a CTSV Owners 200mph national meetup? 😎

I didn't realize there is a track racing forum. @Karch can you please move this post over there? tx

Happy wife - happy life! At least that's the word on the street.

I'm not sure it's the same "Palmer", but I flog my V2 Coupe around the Palmer Motorsports road course here in MA, and while the brakes do heat up after a few hard laps, I have yet to suffer any kind of significant fade. Just that "your brakes are cooking" smell that signals it's time to return to the pits. But I am very "conscious" of how heavy the car is. I am judicious in my application of the slow-down pedal specifically because I know I'll burn the brakes out if I'm overly aggressive.

Glad to see your sense of humor is intact!

It's the same mountain course. I assume you know Chris the track manager. He and I raced together and he a great dude.

I'm sure I've met him. But I'm just part of a group that gets together and rents the track for a day. Helmet required, max of 6 cars on the track at any one time, no wheel-to-wheel racing allowed, "F1 rules", and no timing of laps (but I record my laps so I can time them from the video when I get home). No other rules. I'm not the organizer, so I haven't had to interact with anyone at the track in any significant way.

When we run the track counter-clockwise, there's a big downhill run to the home stretch past the pits. If I stand on the V hard coming out of the turn leading to the downhill, I can get to around 155 before I need to let off and brake. Driving my (ex) blown 02 Z06, I could get to just a bit over 180 on the same stretch.

Palmer CW should be killed with fire. Those are some fast speeds.

Been near 200 on an airstrip
