I glanced at your other post about the 90* turn and now this one, but why are you so hell-bent on mastering a 90* turn? You can practice these techniques (as explained thoroughly by xviper) at any turn, and not necessarily at high rates of speed. If you can become proficient at heel-toe braking (braking, downshifting smoothly), you'll have a leg-up when you head out to an event where you can practice all the turns you want at high rates of speed. Of course I refer to an auto-x or a HPDE (road course). Those are the places where you'll learn how to take a 90* turn among dozens of others, and it'll actually mean something.

I'm not trying to come off as a prick, but the streets aren't a place to learn proper corner entry and exit techniques. Have fun.

 

I believe if you double clutch to rev match, it's okay.

edit: Wait for his answer first, though. I'm no expert, he is.

 

not bend on trying to race on the streets. just found a situation in real life that i have a question about.

and you did kind of sound like a jerk. im just trying to learn. responsibly.

 

I have a question! *raises hand*


Lets say I'm driving 45mph in 4th gear and suddenly a kid runs out on the street. Without hestiation, I would stomp on the clutch and the brake till the car stops.

So now my foot is still on the clutch and I'm still in 4th gear at a standstill. To resume driving, do I just put it in 1st and drive off or do I first shift into 3rd-->2nd--> then 1st and then start driving? Is there a difference at all since I'm at a standstill?

 

dv...

Do you know how to rev-match?
Do you know how to heel toe?

If you don't then your going to have a problem executing the turn at the speeds you want and getting into the gear you want in a timely manner.

It's not necessary, but you can always practice the techniques on the straight with no turn.... over and over till you get the braking with rev and heel toe...

THEN you can practice the technique as you enter a turn.

This sounds like an accident waiting to happen... find an empty parking lot and take some cones or other non harmful objects and make your own 90 turn. first, practice turning as it seems you are having trouble doing that (j/k) next go throught the corner, assuming your starting from 4th, shift down to third and take the turn in 3rd gear, now that you can down shift to third, do it again but go third to second. i assume you cant heel toe since you dont know how to take a turn, so brake, clutch in, shitft from fourth to third to second ( keep in mind your not racing anyone, your practicing, take all the time you need to learn how to do this properly) then when you hit mid corner (apex) rev match and let the clutch out (meaning rev the car to the approximate speed you are going and pop the clutch) either two things will happen, your rev match too high and the car will jump forward, or you will under rev and rear will lock because your not at a decent rpm, and you may spin out. keep doing it till you get the rev match right so the car neither jump forward or locks. once you get this down search the tacing and competition board for some lessons on how to heel toe downshift. or since your local come to my house and ill show you how to do it

 

First of all, 40 mph is too slow for 4th gear for what you are trying to do. You should have downshifted long before this.
If memory serves me correctly, your last thread on this resulted in a bit of an argument and justification for you to do this type of manouver and this sort of driving. I can't remember exactly what the details are or whether it was you or others trying to justify it for you. This is why it would have been better to continue this in that original thread.

Well, now you say you can't get into 2nd easily. No matter how you want to justify doing what you do or how other try to justify it for you, it would seem there is a distinct possibility that you have broken something in your tranny that makes it difficult to engage 2nd. You (or others in that other thread) may have just justified you into a possible repair bill.

There's been a couple of these threads in which I've lately tried to explain the negatives of skip shifting. I hope you are not the latest example of this manifesting itself into a busted tranny. I'm not going to go into extreme details anymore about why or why not to skip shift. This has been beaten to death. If those of you still feel this is good practice, then I can't tell you any different, so I'm not going to continue hammering on this. I seem to recall I got a bit of flaming when I've attempted this before.

You? Flamed? Now why in the whole wide world would anyone want to do that?

Here's my two cents: dyhppy ought to find somewhere to get a (performance) driving lesson or two. For one thing, there's nothing like hands-on experience with a real instructor in your car to help you figure this out. For another, the quality of information available on forums such as this is highly variable (which can clearly be seen from reading through this and previous 90-degree thread), and without prior expertise it can be tough to sort it out.

I will say, though, that I've learned something from this and related threads: I'm more careful about my daily street driving downshift sequences now. HPH

 

Shouldn't you be in second before turn in (at least for street driving)? The effects of over- or underrevving before the turn are much less dangerous than doing so during the turn.
