After reading on another forum, "don't floor it in first if you want your clutch to last etc." It got me thinking I also though the clutch was between the engine and the gearbox. Thus the same forces are on the clutch which ever gear you're in? (unless you slip it)

Is that right or does the clutch fix between the gearbox and wheels? (not that i think it does)

Any other reason flooring it in first (with the clutch up) would cause strain on my car? (aside from tire wear obviously)

So 1st gear makes the same demands of the clutch/engine as 5th gear? Think about it, read the link. You have much to learn, young padawan. You sound as if you have heard it all, and dismissed it.
 
I'm really sorry you're going to have to spell it out for me. As I though the artical clearly shows the clutch between the gears and engine. Thus the input to the gearbox will always be the same speed as the engine. Thus the gear selected is irrelvent?

The more I think about it the more I think i'm right. Do set me straight.
 
1st gear is the forward gear with the lowest gear ratio, so it provides the greatest acceleration. The issue is not the rotating speed of the engine but the speed at which the torque is applied. i.e. assuming you are flooring it through all the gears, the engines peak torque will be achieved much more quickly in 1st than any other gear and some clutches are not strong enough to cope with the sudden influx of power.

You mean first can provide abit too much of a "jerk" for the clutch? That makes sence to me.
 
Sorry this is completely incorrect. In first gear the clutch is under less stress than in taller gears. I guess none of you have experienced a worn clutch yet, but you will find that it starts slipping in higher gears, the reason being that that weight of the car is offering more resistance to the engine, i.e. the engine has to put a high sustained torque through the clutch to accelerate the car. In first gear the peak 'load' presented to the engine (and clutch) is much lower and of shorter duration.

Drag starts where you are slipping the clutch to maintain RPM whilst preventing wheelspin is very hard on clutches, but this is not the same as simply "flooring it" in first.

What he said.


And there is no fun in driving with out flooring it in first:p
