Yes. Unless somehow they are getting to a top speed of 370mph and seem to be engine rpm limited at that.

Absolutely no possibility it’s 370mph, so yeah, it’s in kilometers. That’s 230mph for the imperial measurement folks (still very damn fast, especially for that section. While mostly straight, it is deceptively hard to do in many cars, aka ones not from a professional racing team, at even 150mph, speaking from experience).
