Smooth launch in 1st Gear?

6spd · 03-25-2010, 09:13 PM

like i said above, as the left rises the right lowers, if done correctly and with experience, the motion is seamless. you wont have to hold off from letting up as the car gets rolling.

If the clutch is brand new (ie, less than 1K on it) it'll be a bit grabby. Do a couple takeoffs in 3rd @ around 3-4K (just get the car rolling, then drop to 2nd) and it'll get some material transferred to the flywheel side and smooth things out.

My motorcycle (I know, wet clutch vs dry clutch, still same principals) had a very grabby clutch. I did that (in 2nd, 5 speed gearbox with 3 OD's), a fwe times, and that tamed it.

My (old) truck, I did a take off in 5th (of 5) and BURNED that clutch. Kind of overdid it, but it wasn't grabby, nice and smooth.

Thanks.

Don't try it in 2nd. You need more RPM's! It's just like a good woman.... you need to get the right feel.

yah, i found that you need to rev kinda high before engaging 1st from a standstill on the z compared to other cars. otherwise it does lurch forward/aft a few times while it picksup speed.

The 350Z had an adjustment behind the clutch pedal where you could adjust the contact point higher or lower. You could adjust it so launches from 1st gear were really smooth. Anyone notice the same thing on the 370Z? Check this out: http://www.350z-tech.com/zwiki/Clutch_Adjustment

I would like to lower my contact point... I think it is a bit too high...

I usually lift the clutch right before the engagement point, then give a little gas, and at the same time lift the clutch, the car usually start moving below 1500rpm...
