So I was doing just over 90 in 10th gear and noticed my car wasn’t even doing 2,000 rpm (see pic below),. If my math is correct that means the car is geared to do over 300 mph in a vacuum! However, according to member breplica in the sticky differential swap thread (see quote below) the car is indirectly governed to 268 kph (167 mph) by virtue of the computer preventing the car from going beyond 6,000 rpm in 7th gear.
What would be the top speed without that governor? (Asking for a friend )

Once you hit 6000rpm/7th gear/245km/h the car goes into a soft limiter mode where with the throttle pinned the car just maintains that rpm/speed…
well it doesn't actually work like that, its not direct math - 2000RPM at 90MPH does not mean that at red line you will be over 300MPH. if that were true we could break the sound barrier with some creative gearing! Too much physics involved.

LOL - yeah that’s why I said “in a vacuum” If I had to guesstimate though I think the LC Coupe would do about 190 mph in the real world if left ungoverned and the Vert would do about 180.
