How to limit the speed of chaos vehicle?

My car suddenly exceeding the top speed to 280 and so on… I don’t know what cause this problem. Can somebody help me fix this?

This is the actual video of the speed.

Hey there @BeastNectus! Did you see my other post on your original one?

Is your nitrous thrusters or just increased torque? If torque the hacky way I showed off will work for that perfectly. However the engine RPM curve can already reduce power past a certain RPM though you’d have to do testing.

Thank you sir, I fix it already. I have another problem again. Could you assist me sir? Thank you in advance. Here is the thread I’ve created.
