car moving too slow?

#pragma strict
var WheelFL : WheelCollider;
var WheelFR : WheelCollider;
var WheelBL : WheelCollider;
var WheelBR : WheelCollider;
var maxTorque : float = 5000;
function Start () {
GetComponent.().centerOfMass.y = -0.9;
}

function FixedUpdate () {
WheelBR.motorTorque = maxTorque * Input.GetAxis(“Vertical”);
WheelBL.motorTorque = maxTorque * Input.GetAxis(“Vertical”);
WheelFL.steerAngle = 10 * Input.GetAxis(“Horizontal”);
WheelFR.steerAngle = 10 * Input.GetAxis(“Horizontal”);
}
This is the script i have so far its purely just to make the car move but its going at a snails pace, i tried re-scaling the world but that only made things worse, although the car moved slightly faster, any help would be greatly appreciated. thank you

Add something along the lines of:

float MyTorque = 0f;
float TorqueMultiplier = 5f;

Update()
{
MyTorque += Input.GetAxis("Vertical") * TorqueMultiplier;
}

And then on motorTorque use: myTorque.
