I try to keep my revs >1000 when I'm engaging in 1st.

So here is my process say at stop light flat surface:
1. Disengage clutch (press in clutch pedal) & lift foot off brakes
2. Start to release clutch and about a little before the engagement point I rev up to around 1200-1500 rpm.
3. Once I feel the clutch start engage, I continue maintatin the revs to keep from stalling/chattering
4. as the clutch engages more I start to apply more throttle (the key here is smoothness).

Thanks Arnold K. That's the kind of info I'm curious about.

You'll know if you're cooking the clutch...burned clutch smells like tire smoke + garbage. But again, it takes quite a bit of stupidity to cook a clutch during normal driving.
Yeah, I know the smell from being around others doing stupid things in manual cars. Out of curiosity, what actually makes the smell? Just the friction material of the clutch being overheated/burned?

You can even do that in 3rd gear if the clutch is in good condition.

My friend study auto-mechanic in college here, his instructor told him this is one of the method to test the clutch.

Of course, don't do that always!! :driving:

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.
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.

Most people that do that test are looking for the car to stall, by releasing the clutch in 3rd.

LOL, seriously, I tried it on a manual car, it won't stall, you have to release the clutch very slowly, it determines is your clutch still give enough friction.

But since you have to release the clutch so slowly in 3rd, that's why it shouldn't perform often.

:icon17:

kenchan 02-21-2012 04:44 PM
there was some stupid contest in japan some time ago where you take your highest gear and see if you can get the car going without stalling... without throttle input.

Yeah, similar to cooked brake pads - it's the copper and ceramic bits of the clutch that smell so bad when mixed together.

LMBmikeZ 02-21-2012 06:31 PM
I have been reading a lot of peoples posts saying that the SRM (Syncro Rev Matching) blips the throttle on up shifts. But it is my my understanding even from before I bought my Z34 and was looking into them, that the SRM is actually only on the down shifts. While driving the car I only notice the down shifts being affected. Then with it off I obviously notice no blip on downshifts.

Any way on topic. My bad habit for my Z's which have all been MT. Is I always tend to rev 2nd, 3rd and some times 4th pretty high before I shift, I just love hearing the car roar. Before I know it I'm going to fast......lol. :driving:

kenchan 02-21-2012 06:45 PM
Mike SRM will hold rev on up shifts. Its less noticeable since lower rpm on higher gear but without engaging clutch, hold in higher gear gate entry and let car coast. It will maintain rev. :)

LMBmikeZ 02-21-2012 06:51 PM
Interesting........ Now if only it was spring do I had my Z out to go at around with!!!:shakes head:

NickBaragona 02-21-2012 09:59 PM
For those that say it's bad to put it in neutral and coast to a stop sign. Isn't it just as bad to have to downshift at every stop sign?

Here's my take on this...

A) When you're in gear but off the gas & decelerating, the fuel injectors supposedly close - so you're not using any gas. Coasting in neutral, you're still using gas to keep the engine running. At least, that's what I've always heard with modern engines.

B) Safety. The "real" reason. If you're coasting in neutral, you've lost the ability to quickly accelerate. Of course, hit the clutch, put it in gear, and take-off. But you would need a second or two to do this, and this could be the difference between an accident and just a close call. Put another way, by coasting in neutral, you're needlessly removing an option from your available escape routes should a situation arise.

To be honest, I don't see what extra information this would give you.

The stall-out third gear test isn't really needed to start with(you should be able to tell), but being able to start in third gear by slipping the clutch...that will happen whether your clutch is slipping already or not.

That's always my fear as well, especially if you have a planter or another car in front of you!

wdkwang 02-23-2012 09:54 AM
Well i stalled this morning cause I forgot about it being in first. That woke me up alright

:eek: It's ok . I would advise you shift/ check it's in neutral before everytime you start up. I have a habit in both of my cars to wiggle the shifter left and right to make sure it's in neutral before I fire it up.

Nick911sc 02-23-2012 09:57 AM
I've always been taught to keep my car in gear when parked. It'll become second nature eventually lol. Or you can just pull it out of 1st gear as you're starting the car to ensure you don't accidentally stall.

EDIT: Zman8 beat me to it

ZMan8 02-23-2012 09:58 AM
I think for many cars the manual actually says to shift to neutral before starting the car...I don't do it but does anybody know if there is a danger in starting in 1st.

Nick911sc 02-23-2012 10:01 AM
I've never heard of it being dangerous other than stalling and jolting into a car in front of you. But with the way cars are today I wouldn't be surprised... When I first bought my car I had it in neutral and went to start it without putting the clutch in until I realized it had to be clutched in to start (all the older cars I was around prior to getting my Z would start in neutral without clutching in first, hence why I always made it a habit to check what gear I was in before starting the car lol)

My very worst habit is driving an automatic and instinctually pushing the clutch to the floor, only to find an extended brake pedal instead.

When I drive my gals car I must plant my left foot flat on the floor to avoid this.

Ha I'm guilty of doing the opposite. I got my z for Christmas and hadn't driven a m/t in 5 years. I had just finished about an hour of hwy driving and when I exited I was zoned out and came to a stop with the car still in 6th. Wondered wtf happened... Then I realized. Luckily I was the only one in the car and no one was around to hear my engine restart. Sooo embarrassing

These things happen.

RE: Sooo embarrassing. Locking up the brakes at a crosswalk :icon14: is far from a pat on the back from pedestrians.

Mai-z 02-23-2012 10:59 AM
Back on to topic. Here's something a little funny to think about. I have warranty up to 75k miles. Should I have fun with my z and have the clutch go out at 50k and then baby it from then? Or baby it now and risk natural wear having it go out at 80?

Not saying I dog my Z or that i'll even have it till my warranty run out. But with that kind of warranty is all of the meticulous driving worth it?

I dont think the warranty covers the clutch

Clutches are covered by warranty? :driving:
