Depends on how long you want the clutch and drive to last.
My clutch is fully engaged my 11-1200 rpm for casual daily driving. If you new to manual try to practice.
Get the car rolling with no gas pedal at all, it's not hard.
Next find an incline, hill, driveway whatever and practice feeling where the clutch starts to engage and pull the car with your foot still on the brake, this way the car wont roll back even an inch when you released the brake to get going. Then hold the car there without using the brake, just clutch and little gas. Get good at this and your friends won't even know you have a manual because your shifts are so smoooooth.(thumb)
By the way once you master smooth launch and shifting technique, racing is much easier.
