Ungoverned top speeds

Steeda has a video of an S650 hitting 176 at Daytona after a Palm Beach Dyno tune with the speed limiter removed and rpm limits raised.

Auto DH/PP is 155 and normal auto GT is 145. I have all three tune files sitting here for all three as 2026 modes. Also this is 10 speed cars. I have a manual DH as well, and that one shows 166mph.

this is interesting, because i recall going 163 in my auto DH once before letting off. scary as hell and never doing that again, but it was definitely more than 155

It'd be interesting to see the CDa number for a stock GT. That's a bigger jump than I guessed.

Really interesting to learn about the fuel system!

Specifically, I think it was this one:

Which is also what Ford put into its track experience Dark Horse cars.

And I do not know that it was topped out as against air resistance. That is just the speed they hit before they had to brake to make the turn. Maybe watching the video again we could figure out if there was more, or not.

EDIT: Nevermind, the speed is not displayed on the video, so no way to know.
