I have really enjoyed the new car from the devs of BeamNG Drive. I believe I have set the speed record for it with unmodified tires. 380mph air speed and 399mph wheel speed. Not many other cars I have modded can go that fast without totally changing the engines and giving them 10,000hp+. This car uses a mix of mods all working together unison to work and still be driveable. The boost by gear allows for different boost levels in different gears so that you can tune the power for the available traction. I also use the boost scramble to tack on another 50psi of boost to get the total of 150 ('only' goes to 100). Horsepower level at 150 psi: 2600+- hp at 7500rpm, pretty stout for a 2.5L 5 cyl Mods used: ALS tubro and ECU mod from @gt02 (by far my favorite mod) Indestructible engine mod from @KaMiKaZeE443 (need to get that sound figured out) 7 speed sequential gearbox from @thatguy47 (really cool modpacks) Radiator from @HDR so the car doesn't overheat instantly as all the boost comes in About 1 second after I resumed the game, my tires went to the 4th dimension. They were shaking badly and expanding a lot with the centrifugal forces. I know other cars can go faster (like the V10 destroyer thing) but they are mostly either rocket cars or not of a BeamNG origin. This car has stock aerodynamics, stock tires, the 2.5L 5 cylinder engine of BeamNG origin, a GIGANTIC turbo, and mods based on using and maintaining the power. I mod most of the BeamNG cars like this and normally get good results. Except for the off road vehicles, they are very unstable at high power and speeds. If anyone has any questions on how I did this let me know. I do not see a whole lot of people going this fast on YouTube, how fast have you guys made a car go?
I managed to do two consecutive 420 mph runs using Meo's 454 mod and vanilla drag tires. Diesel 7-speed DCT, race AWD with 16/84% torque split. The last 10 mphs took more than 4 miles to accelerate and then stopping without brakes about the same.
I made the autobello piccolina go 1600 mph --- Post updated --- BUT using the jato mod although the fastest car in beamng goes 12000 mph but thats a mod
