Bad Driving Habits (M/T)

The z can be started like that too I think...very very slow engage of clutch though.

And to Augustus, don't worry you can safely rev it up to 1500 rpm even and engage it at that point if you want a bit smoother shifts.

Thanks for the advice.

So at what RPM does excessive clutch slipping really start to cause damage to the Z's clutch?

kenchan

it can start even 1500 if you ride the clutch long enough.

ZMan8

That's tough to answer because you can damage the clutch by riding it at 1500 rpm and 5000 rpm. 5000 will put more of a load on there which leads to more damange. But say you slip the clutch for 5 seconds at 5000 rpm and slip it at 1500 rpm for 20 seconds. Then i'm not sure which one is worse.

Yeah, ZMan & kenchan, that's what I was wondering.

Like if there was sort of an optimal guideline for a normal speed, low-impact, standard start. I realize that every situation is a little different; desired 'launch' speed, uphill/downhill start, ambient temps, traffic conditions, vehicle loading, whether there's a hottie in the lane next to you, etc.

So engaging the clutch at 1,200 -1,500 RPM, do you allow the RPM's to fall a bit as the clutch engages and the car begins moving? Or do you modulate the throttle to keep the RPM's steady as you fully engage the clutch? Tough question, I realize.

With my near-bog technique/habit, I'm modulating the throttle to keep it around 1k, as I've got to to keep it from stalling.

kenchan

yep, rpm falls a little bit while engaging. i dont modulate the throttle and engage the clutch linearly if just a regular start. if over bumps, crawling, over r/r crossing, uphill, etc i modulate a little bit case by case.

Far more torque down low than a Z to allow either car to just get on up and go off the clutch.

Isn't that necessary in an S2K? In a 370Z you can coast at 5MPH without even a slight buck and comfortably accelerate - I do this a lot at yield, slow down, school bumps, and even stop signs - no qualms from the car. Again, that's because the Z has enough torque to maintain the momentum in 2nd gear at 5MPH.

I've driven an S2000 ages ago, and I recall it not liking being in 2nd gear at anything below 5MPH, you felt it as soon you slowed down past 10MPH in fact.
