Shifting into gear while moving???
 
I have noticed that when I try to shift into say, 1st or 2nd gear while moving at about 30mph, leaving the clutch pressed in till i make the turn, it is seems like there is a bigger gate to get through. Sitting at stand still shifting into any gear is like nothing, but leaving the clutch in shifting while moving seems more difficult.
Does this hurt the clutch or flywheel?

kenchan 07-27-2012 09:20 AM

why are you clutch-ing in till you make the turn going 30mph? get into 2nd BEFORE the turn.

your gate will be stubborn into 1st gear even if the SRM is turned on as you need to time the entry just right. you can, however, tap the throttle to assist the blip (SRM turned on) making your entry window a tad longer.

honestly you need to learn MT on a non-SRM car (or turn it off on the Z) and practice blipping the throttle while you brake.

edub370 07-27-2012 09:38 AM

no need to ever shift into first unless fully stopped. i dont even go into first if i slow down to like 5mph. and as kenchan said no need to press in the clutch to turn. always wanna have a the car in a gear going thru a corner.

i believe every trans has some kind of half locking mechanism thingy of some type to not let u throw it into first gear easily unless almost fully stopped

Be in gear through the turn. Down shift in a straight line, like braking.

TerribleONE 07-27-2012 09:40 AM

:iagree: also.. as others said above 1st is to get you moving.. even if going 5-10mph I am going to go to 2nd. The syncros dont take kindly to slamming it into first at any speed..

houkouonchi 07-27-2012 09:44 AM

if I think I am gonna start accelerating again or in traffic I use 1st all the time. Even with SRM turned off I have no problems downshifting into first.. just gotta sync the rpms' manually. No biggy.

Davey 07-27-2012 09:58 AM

It's harder on the synchros if you shift into a very low gear when moving at a high speed. The resistance you feel is the synchros trying to do their job.

So for example if you are on the highway going 60 mph and you take an off ramp with a sharp turn at the end and you say "OK, I will need to be in 2nd for that turn, so I will just push the clutch in now and shift to 2nd at 60 mph" you are going to feel significant resustance and doing this often will cause a lot of wear on your synchros.

I have been driving MT cars all my life... plenty of experience with heel-toeing and dont have the SRM... You really feel it goes into first with ease as it does when down shifting into other gears? I am not saying it wont go into the gate.. but I have always found ALL MT trans hate it

elmz 07-27-2012 10:04 AM

Agreed. You should be in gear before you turn your wheel. Also, down shifting into 1st at 30mph is a bit excessive - yikes!

As long as you bleep the throttel and match the RPM speed to wheel speed then you are ok. You can be in 1st gear at 30 if you really wanted to LOL. The max gear speeds are below. But like people mentioned earlier, you MUST be in gear through a corner to keep the wheels locked to the engine. Engange the clutch either before the corner or as you exit the apex.

1st - 40

2nd - 65

3rd - 90

4th - 115

Please dont lol

if you are rolling, stick in second.

a) wont make u look like a "because race car" driver. (noob with a mt)

b) first gear on ALL transmissions is not easily activated at speed. will it? Sure! will your trans enjoy it? no

c) refere to a)

elmz 07-27-2012 10:34 AM

^This. There is no need to downshift into 1st, ever. Maybe on a track, maybe...:rolleyes:

dP3NGU1N 07-27-2012 11:34 AM

^If you're in first gear on the track I think the term is "You're doing it wrong" :p

Yes, if you double clutch and rev match so the synchros don't have to be overworked, you can downshift into 1st at 30, but if you did that then you won't feel any additional resistance and you wouldn't be posting this thread.

The point was that he shouldn't be cramming the trans into any gear at any mph because yes, it's hurting the car. :tiphat:

regarding 1st gear: LOL well I never said you should... I said if you "really wanted to you could" I wouldn't recommend it though as the the second gear has plenty of power band to get you up to speed quick :)

double clutching really hasnt been needed since like the 40's. the advent of synchros eliminated that from common practice. theory being, double clutching matched gear speeds. but now u got synchros to do that for u

Tward 07-27-2012 02:18 PM

What is SRM? Not familiar with that abreviation.
To give you guys the exact scenario i go through every day driving home; my street is off of a highway at which i am going 55 to 60 mph, before i get to the turn, i engage the clutch, put it in 3rd, start braking and when i make the turn begin to release the clutch and continue on my way. Well when i shift into 3rd it feels like there is a massive wall

Correct, the synchros do that. And in doing that, they wear out. Especially if you are trying to cram the car into 1st gear at 30 mph, or 2nd gear at 60 mph. The more they have to synchronize the speed due to different rotational speeds, the more they have to work, which is why it's difficult to push the shifter into 2nd at 60 mph, etc.

So you can either not shift into 2nd at 60/1st at 30, or you can double clutch and rev match to assist the synchros and avoid excessive wear, or you can wear out your synchros, it's up to you. :tup:

srm = synchro rev match. the system that blips the throttle for u on downshifts on the sport models. wait so 3rd is difficult to get in? i thought it was 1st at speed?

Tward 07-27-2012 02:24 PM

I have the nav model, not sport, sorry i didnt clarify that. So i dont have SRM.
In my first post i wasnt really thinking, and was just generalizing, i never use first unless i am starting off.
To make it clear i am basically just asking if down shifting hurts the clutch and flywheel?

not if you blip and rev match

robones 07-27-2012 03:26 PM

The worst thing you can do for your clutch is depressing it slowly to go into gear. You want the clutch and fly wheel to have a quick and almost immidiate contact at the lowest possible RPM to avoid added wear. The more practice the better you become and the feeling will almost replicate the smoothness of an automatic. :)

High RPMs shifting and downshifting will prematurely wear the clutch regardless whether or not you rev match.

Footloose301 07-27-2012 03:31 PM

Granny shifting. Not double clutching like you should. http://becauseracecar.org/wp-content...NG-650x432.jpg

Can you explain "depressing it slowly to go into gear"? Are you saying it's bad to depress the clutch slowly while in gear?

kenchan 07-27-2012 04:33 PM

perhaps he means riding the clutch

So what would be the best way? Turn, then downshift to 2nd and accelerate?

This is what I usually do on sharp turns. The thing I don't like about it is I can't accelerate right away after that.

kenchan 07-27-2012 04:36 PM

brake and rev-match downshift to 2nd while straight (setting up for the turn), turn with partial throttle open, once you're through of the apex, open it up.

guys, you are scaring me... you dont know how to drive MT and bought a sports car?!!! :facepalm:

Lol I'd like to take turns at 40+mph if possible :D

But yeah, I learned to drive MT on this car so there are lots of things I still need to learn.

watch best motoring videos on youtube and you will see how the race car drivers are setting up for the turn. they have camera shots of tach and feet (and audio) so it should give you an idea wat you should be doing.

if you have SRM, it's very easy to do, obviously, but even if you dont it's not too difficult to rev-match while braking if you practice. GL.

No, you downshift to the correct gear for the speed you will take the turn at before you get to the turn... But not too far before the turn.

But never double-clutch. That's for pre-1940's trucks. :tiphat:

Why does my z stall when I come to a stop. I have to keep pressing the clutch and starting the car at every red light.

:roflpuke2:

You would think for $40,000 they would keep the car from stalling like that, right? :confused:

Jsolo 07-27-2012 08:11 PM

If you're letting the clutch out after you've already turned (or through the turn), it helps to blip the throttle slightly to get the rpm near where they should be. Otherwise being in the correct gear before the turn is a good idea too.

ChrisSlicks 07-27-2012 09:01 PM

Teach yourself heal-toe so that you can blip the throttle while braking and downshifting. It will go into 3rd easily, probably no need for 2nd unless the corner is tight or you're really looking to rocket through.

Tward 07-30-2012 08:51 AM

How are you guys heal toeing with our car. All the videos i have seen have a different gas pedal set up. I am only 19, first manual car, so trying to learn everything the right way so its not difficult to break a bad habbit

If you guys dont want to help us out dont bother posting anything. Trying to learn the best way to shift a manual car, most 19 year olds these days dont even know what a manual car is. Just looking for help to be a better driver.

The easiest way in this car and most modern cars: brake with your foot mostly on the right hand side of the brake pedal, then while still applying pressure to the brakes, roll the ankle so the side of your foot blips the throttle as you down shift.

The hard part is 2 things (that will take lots of practice), keeping the brake pressure even, and getting the correct target RPM. The latter isn't critical, but the closer you are the smoother it will be. Also your clutch action will be much faster, you can essentially treat the clutch as an on-off switch.

Practice by coming down sequentially through the gears while braking from moderate speed, and once you've mastered that you can try skipping gears.

You can also practice your throttle modulation by downshifting while travelling at constant speed, e.g. cruise along at 55-60 and do a blip downshift from 5th to 4th and from 4th to 3rd. Once you get it right it should feel completely smooth and seamless.
