How to increase the speed in this car chassis?

Hi, I have a car chassis but, I don’t know how I increase the speed:

Change the Horsepower. The horsepower should change the speed of it with it.

Yes, I also experienced the same problem with free advanced models but
the way its arranged should be self explanatory. try changing the value of
the Tune.Horsepower maybe like… 250+? and PeakRPM to 10k? IDk
Edit: Oh right when I typed this, Jry already replied hehe, ignore this reply

Okay, I’m testing the PeakRPM i changed it

Increasing the PeakRPM decreases the speed! what do I do now lol

Horse power above 500 do it, if not then tune back the PeakRPM to 600?

Nope not working at all O_O im gonna try mess around with properties

Mess around the Engine properties, increase it value, lower the value

All you need to do is increase horsepower, maybe revacc as well for acceleration
