Just for fun, as it can go to 50 m/s, it isn't a real dragster, but that's already a lot.
Just hold UP to accelerate, the thrusters and the springs will get 10 times the force they already had, and this will get shot. If you brake and accelerate at the same time, the clutch will be off, but the gearbox will get max gear, and when you release the brake... !
Upd1: 4wd now. Low drive with L (engage in 1st, 2nd or 3rd gear)
END to turn on thrusters (toggle).
Upd2: Fixed thrusters orientation. Lowered force of engine.
