Fastest Speed You Reached In Vanilla Game. (No Mods)

I got the rear rims of a moonhawk to move at 1045 km/h:

 

Those weren't even rims at that point... ^^

Also, 522 × 2 = 1044.

 

Actually the rims were intact just before I took the screenshot at ~1040km/h (I was in 100x slow motion so I could see this)

Also, I was looking at the wheelspeed debug app because the speedometer tracks all wheels not just the rear wheels. The RL wheel is moving at 1045.47 km/h.

 

So this is my new top speed.
Thank you for the tip with the Race LSD. That worked.
But now, engine overheating is the new problem. Even the superradiator mod overheats at that speed. For some reason I get better cooling with the High performace radiator than the modded super radiator..
Any tips on better cooling?

 

Strange, I've never ever had any issues with that Super Radiators-mod, it has always worked on every single car flawlessly. Perhaps the turbo got too hot and it boiled the engine.

 

I see your NON-VANILLA top speed and raise it with my new VANILLA top speed:



EDIT: Yeah, it's just the wheelspeed... My point is we should use the airspeed.
