Need some street tips

Just wondering wat all this talk about double clutching and powershifting. are people watching F&F too many times? or could i actually learn the tricks of the trade and improve on street drag acceleration. also my friend and i have this arguement about downshifting ie: going 40 but need to slow down to 20 mph for a turn and still keep the rpms up to race out of the turn. sorry if i sound dumb. just wanted some imput.:bandit:

Powershifting:

Shifting without lifting off of the gas pedal. This is accomplished by stepping on the clutch while keeping your right foot on the gas pedal, in extremes floored, even. You must be VERY quick with this so you don't compromise your engine by bouncing-off the rev-limiter. This technique allows you to keep you're RPMs at your power-peak, but at the same time "slams" your clutch like you would in a drag take off...ouch. Use with caution.

Double-clutching:

The same principle as the powershift, except you are just basically "slamming" the clutch down but are NOT upshifting or downshifting. Useful for when you are in a top-speed race and have reached the limits of your top-end due to air-drag, but still have some RPMs left in your motor. Accomplished by stepping on the clutch AFTER it has engaged in gear, while keeping your right foot firmly planted on the gas pedal, then releasing the clutch, effectively "dropping" your clutch while your RPM's are high. This produces a slight "take-off" effect just like when you launch by dropping the clutch. Be warned, if you are slow, this motion WILL slow you down instead, because for a brief moment, the clutch will not be engaged, and you will be effectively coasting for this brief period. Use THIS with caution also...IF and WHEN your particular car needs it.

Keeping the revs up while turning a corner:

WILL make you exit the corner faster. This is called rev-matching. You are basically keeping your revs up in anticipation of releasing the clutch when you come out of the corner. This maneuver will keep your engine on the good side of the powerband, allowing for a quicker corner exit, as opposed to allowing your engine to rev down, and having to climb your powerband again. Be careful with this move on RWD, high-TQ cars...a spin-out is not fun when you weren't looking for one. One of the more popular and easiest ways of accomplishing this is with heel-toe shifting. This is done by stepping on the clutch as you brake for the turn, which is normal...what is different is you step on the brake pedal with the heel of your foot while keeping the upper part of your right foot on the gas pedal...not flooring it, which will just make your tires spin, but just keeping the revs up enough so you neither bog the engine or spin the tires. Takes some practicing, because you need to be able to do all this while concentrating on a turn. Do NOT practice this on city streets with traffic around. Also, if you crack any part of your car while doing this, it's not my fault...I warned you. Also, this maneuver is only mostly effective in sharp turns. On wide sweepers, you can just stay in second/third and lay on the gas, relying on your traction to hold you through.

There you go...enough info for ya?

thats the last time i listen to talk to my friend about car driving techniques ........ O so thats what double clutchin is :D

Actually, double-clutching is the proper technique you use to downshift the car at speed...Example...
You're in fourth gear and want to downshift into second gear. You press the clutch in and shift into neutral, at which point you let off of the clutch. You then use the accelerator to bring the engine speed up to where it needs to be for the lower gear. The clutch is then reengaged and you shift into the lower gear. What this does is reduce excessive wear on the transmissions synchronizers and also allows you to downshift without the car "jumping" like I'm sure most of you are used to.

That's also the way you shift without using the clutch...Hit the gas, ease it out, rev-match, ease it in...Very difficult, you have to be perfect, or your synchro's aren't going to be very happy...And neither will your pocketbook:D

so guess powershifting if not nessesary nor good for the stock clutch tht i have. does double cluthing also induce excessive wear on my car?

NO! Read MY description of what double-clutching is...It's GOOD for your car and reduces wear. It's the way you're SUPPOSED to downshift your vehicle ALL of the time. As for powershifting, heck yes it's bad for the car. Don't do it often, lol.

Basically all you need to do is shift fast. The traditional method works just fine and can be done as effectively as power shifting without the catastrophic impact on the clutch and trans. Just practice.

no wonder my clutch is acting funny.
:cry:

Okay. I've always heard of the maneuver you described as just simply rev-matching. What then would the manuever I described be called, then?

I've no clue...I've heard of what you mentioned as well...I was trying to think of what I heard it called earlier so I could add it to my post but couldn't think of it for the life of me. It's definately a real thing though, it like makes the car "skip" forward and bumps the rpms up a notch...I'm gonna check around, see if I can find out what it's called. It's really naggin' at me, hehe:)

man my friend was right ? no peeps we need to get this straight

From what i know isnt match reving part of down shifting? some people downshift simply by shifting to A lower gear then feathering the clutch to slow the car and the engine down, and yes its true that is u just shift to a lower gear and let the clutch out the car will jump forward and it can be kinda scary. but if you are going 40 for example. and want to slow down to 20 for a turn you should follow wat carnuttt says cause hes correct and thats the way i downshift. cruising in 3rd going 40 mph i shift to neutral "blip" the gas (hit the gas a little so rpms will be higher when you shift into second. then you can let go of the clutch faster and have much better acceleration out of the turn then without the blip on the gas peddle. if im wrong just correct me guys. remember im just a newbie and i am here to learn stuff from these post. not here to be a smart ass.

:devil:

Wait, it's always been my understanding that double clutching for acceleration died with the 70s. It used to be mandatory for a car to double clutch to shift gears. Now our engines are a little more advanced and we don't have to do that anymore. Am I correct? (lol, I'm confused now)

Forgive me if somebody already said that. I'm @work right now and only had time to fully read through the second or third post.

Yeap, you're exactly right. Now it's only used to DOWNshift. It's the correct way to downshift actually, and everyone should do it as a way of taking better care of their vehicle.

alright! I was right. And that line in F&F was complete bullshit like I thought... "not double clutching like you should" or w/e... I laughed out loud when I heard that. Well now that I think about it, unless they had turbos, in which double clutching would be good because it spools up the turbo. (lol, or at least that's my understanding) and doing 10s off of NOS alone I'm guessing would be a bit difficult but possible. But they never did mention anthing about turbos so i guess it's still bullshit.

They DID have turbo's in Fast and Furious...Supra's Rx7s, GSXs...Those are all turbocharged vehicles. And they also mention them, remember the line, "I see a cool air intake, a t-66 turbo, and a NAAWWSSS Fogger system, Dominic"...hehe, remember? But anyways, the turbo's are definately there in the movie. But double clutching still wouldn't be helpful...

OOOOOOOHHHHHHHHHHH YEAAAAAA.... that's right. Well I didn't pay much attention to the movie, really. I thought It was stupid in terms of REAL street racing and thre were so many stupid lines and pathetic mistakes and only succeeded in tossing us hundreds of ricers who saw the movie and 'they wanted to do that too!'. Gawd I HATE it when I talk to somebody and they mention F&F and were like 'oh yea I saw that movie and KNEW I was destined to do that. Then they get in their 89 civic fully equipped with the aftermarket colored emblems and kewl washer lights and roar off into the night. :finger:
...But yea you're right. They DID say that now that I remember. So you're saying double clutching is absolutely pointless (in accelerating)and it doesn't do w\e turbo crap I was rambling about? alright. I got it now. lol

I would think it would with a turbo car at high boost. Powershifting might be a bit too much in such a car, so a little bit of rev-matching in the form of double-clutching(to spool the turbos, like somebody mentioned), should be helpful.

Oh, and by the way...

From The Dictionary of Automotive Terms and Abbreviations:

double clutching:
Vehicles with manual transmission and no synchromesh have difficulty shifting from one gear to another. With synchromesh, shifting is accomplished by depressing the clutch pedal and moving the gearshift selector from one gear to the next. Without synchromesh, shifting is not smooth unless you double clutch. Here you depress the clutch pedal shift to neutral lift up on the clutch pedal blip the throttle (accelerator), then depress the clutch pedal again and shift to the next gear. While this action seems complicated, you can get used to doing it to avoid the grinding noise heard in non-synchromesh transmissions.

isnt double clutching the same as in Le Mans racing ''heel toe shifting" where you just keep the gas up and then when you slow down you uuse the brake and clutch at the same time or the gas and clutch @ the same time?

Somewhat, but not quite. Heel-toe implements part of the double clutch technique, but you can still double clutch without heel-toeing per se.

yeah f&f was only cool cause it was the first modern movie that people could "compare" with to real life. And they had nice cars. LOL and lucky me i found out F&F2 is coming out starring the supra some nsx's s2000 and some european and japanese only cars. Whooooopie fricking doo. anyways just wanted to thank you guys for replying with answers, now i know that i downshift correctly and my car aint from the 80's ora semi truck so i won be trying no double clutch while accelerating. :smoker2:

Actually, the "star car" in F&F2 is a "Blackbird" Skyline(designated by MotoRex, who modifies and sells the car as such for about $100,000). It runs low-to-mid 11's and tops out near 200MPH. All this with full warranty. It's a bargain as far as performance goes, considering the $200,000plus Ferrari 360 Modena runs "only" high 12's and tops out at 180-190MPH.
