There ya go, hope you like it I enjoyed reading it, very easy to understand |
pretty interesting, but very long.............I got to about half way and I gave up.....................will finish it some other time:D

nice execellent source now i just have to go and pratice, the heel and toe, ill try it in a dead parking lot, abandoned with no cops.:D

I took the time to read this article last week. I was taught how to drive stardard in the early 90's from my father before I had my permit. After getting my permit, I drove a 5 speed from them on except for when I had my park avenue for a short time period.
I pretty much knew the mechanics of the engine/clutch/transmission set up and knew about abusing them vs. driving hard vs. babying them. When I drove my saab 900 turbo in HS, my friend taught me the double clutch technique for initial cold weather driving, to make the shifting easy in older transmissions. It worked well, but I only had to do it on the saab. I feel as though I drive my cars hard now, but are not abusing them. I loved my '01 ES 2.0 which I drove for 18 months before getting my '03 Protege5 one month ago. I just turned 2500 miles on her allready and have to get her oil changed soon. Then I can start driving her a little harder and seeing how she will handle. I imagine that the Protege5 will handle like my ES 2.0 (maybe a little better)? I am looking forward for the spring so I can put the Dunlops back on, which I think are great tires for the dry pavement. Have to use snow tires in Mass, especially since I do a lot of driving for work in all conditions and can't afford to get stuck. I also think the Dunlops suck in the snow...... Well, getting off track here.....just wanted to say that that article was good and I enjoyed reading it. I hope others have, too. |
I get an error getting to the page. :(

works well
i read this yesterday so i figured i would try it out today and i can tell a big difference in how smooth the shifts are when u do what it says.

Great info!!!!!!! thanks much, IM sure that its gonna help my driving

Nice Article
Pretty cool article. I had discussed this before with a car enthusiast who used to race SCCA type races. He used to talk about "clutchless" shifts. If you match revs just right, you need almost no clutch to go from one gear to the next. I've only been able to do it at very low speeds, but it is an interesting concept. The idea is that you better understand your car and where the gears mesh up and master the smooth shift. It's a bit of an art.

Shifting without the clutch isn't that hard...it just takes practice. I don't have it down 100% yet (3rd to 4th gives me trouble sometimes).
You just have to figure out how much pressure to put on the shifter at the right time...and it just slides in. The first time you do it without touching the clutch pedal it feels awesome. I don't do it regularly, just to impress friends, and if I'm stuck in traffic constantly switching from 2nd to 3rd and back. (Yes you can downshift without the clutch too by blipping the throttle). |
broken link
anyone seen the acticle elsewhere , link seem broken again

heres the same site for those of you that cant get the other one to work cause i cant either

double clutching with modern synchro mesh yields little to no results...however heel and toe shifting can be helpful in accelerating out of a turn, but until you master it yeilds very little too....keep in mind most of these techniques apply to older transmissions
|
Yes, older transmissions indeed. The heel and toe shifting is used for drifting and racing. I'd advise against people using this outside of these situations if they have synchros. I have a couple of slight weight shifts when I do shift once in a while, but mastering a transmission with just your left foot and hand is good. By doing this you'll get a sense of knowing your car better and even mastering a part of it. Even the pros use the clutch when they shift. Just do it quickly and smoothly. I shift without letting my foot completely leave the gas pedal, but I am not applying gas. It is all in letting the gas off slowly and then cutting down the time you have the clutch disengaged so the tires and engine don't have time to be going faster than the each other. Work on it and get better. There is nothing like a clear day with the windows down and a manual transmission.

wow back from the dead !
no posts on this since 2004 ... :chomper: |
Haha. Well, here's my .02 anyway, since it's been resurrected.
I have never been able to heel & toe, I guess I'm too clumsy or something. I kind of have my own technique of downshifting while braking. When I'm ready to shift I place my right foot so that it rests on the brake and throttle at the same time, then brake with the ball of my foot and rev-match as I shift by 'flicking' the right part of my foot on the throttle. |

The synchros in your transmission are what allow clutchless shifting (I couldn't see that article, so I don't know what it said). Basically, as long as the revs are matched to your speed, you can shift without the clutch.
For example, if your engine revs 500 rpm less in 4th than in 3rd at a given speed, that is how many rpms you need to DECREASE on the upshift, or INCREASE for the downshift - when the rpms are correct for the vehicle speed, you will be able to push the shifter into gear. Of course when you are learning, you will grind gears, so it's not for the faint of heart. What jersey is saying is to blip the throttle to increase the revs the appropriate amount for the dwonshift, so the shifter will slide in when you downshift. It is a neat thing when you get it. you do have to apply some pressure to get it to happen, but as long as you don't force it, it won't go into gear if the rpms are not matched to the speed. I have a P5, and I don't shift without the clutch as I have a hard time matching the revs consistently. I had an 87 VW, which I only ever used the clutch from 1st to 2nd, and from 3rd to 2nd (never downshift to 1st unless you are pretty much stopped and have the clutch in...). Hope this helps :) |
I have seen people talking about heel and toeing using their heel on the brake and toe on the gas. I can't understand how this will work. I can't recall where I originally read about the technique, but you use your toes on the brake (to allow for the best feel) and your heel on the gas to blip the throttle, increasing revs enough to match engine speed to road speed on the downshift (with most cars you will be rolling your ankle and using the side of your foot on the gas pedal). Anyone who rides a motorcycle should know about this. What you are trying for is to minimize the changes to the car's chassis while cornering, and getting the engine into the meat of the powerband in order to maximize exit speed. It really isn't a difficult skill to learn, and once you do it you will never think twice about it. If you ride with someone who doesn't use it you will cringe (like when I was with my brother-in-law in his Honda S2000. The man has no clue about matching revs, it really sucks).
Oh yeah, and this has the added benefit of reducing wear and tear on your drivetrain. I have never upshifted a car without the clutch (have done so on a bike), can't really see the benefit. |
rev-matching every single shift (especially downshifts) is ftw
I heel-toe .. but not with my heel and toe. With the Mazdaspeed pedals on my 3rd gen Protege, there is a lip on the brake and accelerator pedals bringing them very close together.. I just put my foot in the middle and tilt to vary the pressure to each pedal. |
