or you can go into second before shifting into first
This is a great topic, i strongly recomend reading the highly acclaimed book "drive to win by carrol smith" it is a supurb read (cant stress enough) that anyone should read if you are into performance driving. Shifing is really covered in depth. its a great book, its made me realise that you never run out of things to work on your driving technique. Even the likes of schumarker (sp?) never stop trying to better their technique. Every time i get in my car i try and better my heel toeing, making my rev matching as accurate as i can, choosing the best lines, turn in points, shifting points, breaking points etc etc etc.......
I think most people learn how to drive decently, then just keep on doing it that same way, they dont put in an effort to improve their technique, when there is an unlimited amount of improving and refining that can be done.
Alot of my passengers comment on how smooth/seemless and flowing my driving is, which i take alot of pride in. I work on Smooth seemless braking and downshifting (the goal is to keep the deceleration as constant as possible through the hole range of deceleration), smooth cornering (its all about the smooth transition of lateral g forces), seemless upshifting (harder than seemless downshifting) etc. the list goes on.
I feel that this is an excelent way to improve your skills on the race track, as being as smooth and seemless as possible allows you to push closer to the limits of your tyres, without slightly stepping over the boundarys of grip. ie, you need less of a margin for the slight variations in lateral and lonitudinal g forces.
dont be confused that this requires to drive in a illegal manner, you can improve yourself completly obeying the speed limits.
My style of driving is very much like Dylanamus's
You obviously need to brake for corners where you need to slow down for a sharp turn etc, but alot of things, like coming up to a clear roundabout, requires using the brakes barly at all. Say you approach the roundabout at 70kph in 4th, take your foot off the accelerator, and blip the throttle and drop in down to 3rd about 50m or so away, just not having your foot on the accelerator is enough braking, by the time your at the round about youd be doing maby 50kph. If its a really tight roundabout, feather the brakes real slightly and drop it down to second. My brakes rarly get used when cruising around town, unless im required to slow below say 30kph.Quote:

Too low revs (or to higher gears) wont provide enough decelereration. Honda engines are made to be rev happy little creatures, it dosnt really use any extra fuel when not accelerating.
I totaly agree with what dylanamus feels about minimising the amount of breaks you use, can help you for when you get out on the track.
It has been showen that amature racing drivers, over used the brakes much more than need be, compared to a professional drivers. They need more cooling capacity for the brakes than a professional does. they downshift to late (at lower rpms) which requires more work from the brakes for an equal rate of deceleration. If you wanna know more, READ THE BOOK:thumbsup:
Cornflakes, if your engine is shuddering, your in the wrong gear for the speed your doing. youe engine is simply dropping out of the rev range that it should be working in.
If you need to slow to 10kph to take the corner, when the revs are getting low in second gear, drop down to 1st.
Droping down to first is more of an art than dropping down any other gear. It will take longer than any other shift aswell. its also harder to learn. There is absolutly no reason the gears should crunch, if they do your not doing the shift properly.
When your at the speed to downshift, clutch in, push the gear to neutral, blip the throttle to matching revs, at the same time having pressure on the gear leaver, it will fall into first itself from neutral, you dont push it as such into 1st like other gears, thats when you get crunches, you let it drop itself into first when the gears match speed from the sinchros.
The main thing when doing this though, is matching the revs as you release the clutch to keep the deceleration smooth, if you dont match revs, you will decelerate very quickly, and it will be extremly jerky! not nice.
It sound like alot of steps but its not, alot of practice makes it a quick smooth one step exercise. You learn how much is the perfect amount of pressure to apply to the leaver for it to drop quickly into 1st smoothly and without crunches.
good thing is, dropping down to 1st instead of clutching in 2nd, is youl have plenty of power for corner exit, which is good in an emergency where you need to get up to speed cus of an aproaching vechicle that you may have missed, or for sudden deceleration cus of unexpected pedestrians.
Riding the clutch, instead of dropping to first when it is necissary, would be worse on the clutch because as you engage it, you will need to accelerate slightly and slip the clutch till the car is traveling at a speed where you can completly let it go without the engine shuddering. And youve got very little power on tap to deal with emergency situations at such low rpms.
Using this method of staying in second and clutching to stop engine shudders, is for grannys and soccer mums IMO.
Coming up to a stop sign, i prefer to wait till the revs get low in 2nd, and just clutch it and break to a stop, put it in 1st, and take off.
Once again read that book, its great, its very technical. there are so many aspects to driving a car more efficiently and heathily in a racing situation that can also be applied to driving well on the street.
Professional drivers drive their cars on the absolute limit. That's why they are professional drivers. No one drives on the limit on public roads, it's common sense. You can't compare the two. The only common ground is the fact that they are both cars, and the drivers are using the same technique to control them in the most efficient manner. So the answer is yes, it is realistic. Or rather, i'd much rather be in the car with someone who understands these techniques than Joe Goat who drives his corolla from A to B every day, as even though it doesn't prove any knowledge of understanding how a car reacts to the road, it shows a genuine interest in driving which makes far more likely.Quote:

I think the factors are =
1.big balls ( IE confidence)
2.lots of experience of how a car will handle in most/all conditions / situations.
3.big balls.
that's right, if you think your balls are not big enuff, then consider doing some ball implants or ball enlargement...
quick question.., wat is the thrust bearing?
its another name for the "release" bearing inside the gearbox , that pushes against the pressure plate diaphragm , and disengages the clutchQuote:

i cant see a picture??
wat is deemed to be able to drive manual - if it is to get it moving then i can. but i got a question, wat does rev matching mean
I most agree with this as all you can do is just take out ur car and drive drive and drive. Not down a single street of course but many different situations and they all require different action. Of course a familiar road i.e. the road home will be useful for trying new tricks on as you know this road extremely well and can notice the subtle changes in ur car's reactions.Quote:

Best time to learn how to drive is when your still young and willing. Back in the day when I was young and ahem... may have been a bit too young, I loved driving so much every moment I breathed in and treated like a learning experience. I appreciated everything i did and learned and because i was so into it and I was young with my MEGA BALLS and blase attitude to my own life I had done many things that I would never dare do anymore but just I had done it I had gained the experience and skill to do it again and again till it was a science.
Anyways long story short, some things you just gotta take a chance, some things you obviously can't. Use your common sense. But you'll never be a great driver by just reading about pro techniques and never taking a chance.
another noob question with the manual
how can u tell if the clutch is burnt?
and how to test it?

Rev matching means blipping the throttle to get the revs up to match the correct RPM before releasing the clutch when you downshift. It makes downshifting much smoother.Quote:

instead of like heel, toe and gota use the brake as well

but yeh, when u go around a corner for example, and u've gone from 3rd or 4th down to 2nd on the way out...rev matching helps a lot with getting a smooth exit, specially for us FWDers...
Yeah, you could clutch in and blip but whats the point? Why use your transmission to slow you down when you have breaks.Quote:

engine brake is a beautiful thing brother...
dont shift back to reverse while moving forward?
Heel toe is ONLY for braking and downshifing at the same time. If all you wanted was to downshift for more acceleration, then you would just blip the throttle to rev match.Quote:

umm different car, different clutch, different engineQuote:

It shouldn't if you are doing it correctly. Its all about having the feel for the clutch.Quote:

question, are there any adverse affects from shifting to neutral without the clutch?
sometimes i take a little pressure off the gas, and a little pressure on the gear stick and it just slides into neutral, and then i clutch in to gear up.
yeah i use to somestime drive without the clutch
but yeah as the revs drop you can slide it in gear or back to neutral
I've only just started to drive manual 5 months ago and rev matching is one of the first things i learnt. Knowing the gear ratios really help. Being in gear during a turn (with enough torque/rev) is MUST, I learnt this the scary way. I once did a 90deg turn from a 70kph street and did not bother to down shift and turned the car in 4th gear. My car understeered and I almost smacked onto the side gutter.
From then on, I forced myself to be in the right gear when taking corners. I usually brake till ~40kph drop it to 2nd, rev match to 3000rpm then enter the corner while feathering the throttle.
Now I need to take some corners more efficiently and learn to rev match into 1st gear. I haven't been brave enough to try that yet.
So is it safe to drop it to 1st gear as long as my car is moving slow enough and enter a corner in 1st gear? I only rev match btw, I don't double clutch. I find it hard to move the car to 1st unless it's travelling really slow.
If you learn to double clutch, you can put it into 1st while moving (as long as it is below the max speed of 1st gear). Using double clutch, I have put it into 1st without any resistance while moving at 50km/h (max is 60km/h in my car).Quote:

Its probably safer if you have mastered heel-toe technique because it is a better/safer method of taking corners fast because your foot is on the brake into the corner and gets u into a safe speed to take the corner.
If you're going to practice heel-toe then i suggest you drive with your right foot bare because it is easier to maneuver.
So basically heel-toe technique involves:
-approaching corner
-toe on the brake and brake accordingly to a safe cornering speed
-depress clutch peddle & shift to neutral
-release clutch peddle & angle your foot thats still on the brake like this \ then blip on the accelerator with your heel to rev match
-depress clutch peddle & shift to 2nd
-release clutch peddle and corner
To know that you've successfully heel-toed it, it should feel like your driving an auto car thats braking and turning into a corner, should not jerk after you've shifted to 2nd, the only difference is that you can slingshot out of the corner cuz there was no engine braking when you rev matched it.
"release clutch peddle & angle your foot thats still on the brake like this \ then blip on the accelerator with your heel to rev match"
i thought u dun need to release clutch for that part? just keep the clutch depress
^^ Yeah, for some reason he's been heel-toe double clutching instead of just doing heel-toe.
Figured that was the correct way of doing it because it puts less wear on the clutch by not burning it? I donno thats how i learned it and it just stuck to me :)
Rev matching puts less wear on the clutch. But what you are doing will put less wear on the synchros as well. No harm doing it if you have mastered it.Quote:

coz when u put it to 2.. u can feel the car pull... dont like dat feeling..
hawhaw
^^^if it's pulling then ur revs are too low. thats u rev match. or in other words rev UP ur engine so when the rpm needle falls down, it matches the desired rpm needed for that particular gear for smooth/stronger acceleration (and no engine breaking).
and yea, about the 1st gear i did it today. yea sure it works. can't see any reason i would need to use it though. but coooool.
I never put my car in first unless im stopped, or moving at snail pace, she doesnt like to be put in first.
At 50km/h, it's about 5500-6500rpm. Try putting your gear in neutral, releasing the clutch and blipping to about 2500rpm and then putting it into 1st. It should go in without much resistance.Quote:
