i know some of my friends don't step off the accelerator when they shift gears... is this good or bad? i tried it a couple time... you have to shift damn fast or you'll redline. will you run faster by doing this?

 

that sounds pretty complicated

 

Its called powershifting, if makes your runs faster, bu tits bad for your car

 

Incorrect, it is POSSIBLE that it MIGHT make your car faster. My brohter tried this on his Prelude and his times were slightly slwoer, taking into effect tha his reaction times and 60 foots were almost identical each time, the car still went slower while powershifting.

 

SLOWER !!! powershifting keeps the rpms on the powercurve alot more than grannyshifting as far as running slower he must not know how to do it yes POWERSHIFTING IS BETTER ASK ANYBODY THAT KNOWS HOW TO DRIVE A CAR if u granny shift u might as well have an automatic

 

it's only faster if you double-clutch like you should.

you've been watching too much fast and furious.



p.s. your rpm's drop regardless when you get into a higher gear.

 

ok, since my brothe is so horrible at driving his car, then suppoose the following scenario.

You are racing, you shift at say 59 mph (redline in 2nd gear), and your rpms go down to say 5000rpm (not trying to be realistic).

Then say you power shift and shift at 59mph again, excplain to be how your car is going to go to 5500 rpm instead of 5000rpm.

The millisecond that you gain in powershifting will not affect where your rpms fall. It will not have any affect (unless you are in a high horsepower car) while driving the CL in the qaurter mile.

Now put down the crack and go watch the fast and the furious

how the heck do u double clutch(it takes to longdumbass) a new 5 speed and u dont have to run a car to red line most cars put out their peek horses before redline and if u can actually drive the rpms dont go past redline WATCH PROSTOCK IM SURE THEY DOUBLE CLUTCH
new cars have a fully secronized tranny the only reason that u would have to double clutch is if ur an idiot BACK IN THE DAY U COULD DOUBLE SO THE TRANNY RPMS WOULD KEEP UP WITH THE ENGINE
oh im sorry ya'll know everything

 

Ask any luncher, any real luncher. It doesn't matter if you win by a fry or a whole burger, so long as you finish your meal first.

 

lol, I like that

 

it was a toungue-in-cheeck comment dipshit.

the problem of shifting at peak HP is that on our cars you run the risk of falling out of the powerband by the time you shift (wether you're on the gas or not)

double clutching is used on downshifts in autox and and racetracks. it causes a smoother transition to the lower gear and helps cut down on clutch wear.

trans RPM's hardly ever match engine RPM's becuase of gearing. only time they are close to identical is when you have a 1:1 ratio (3rd gear in most cars)


oh..... and by the way.... im not saying i know everything, so wise up and drop the hard-ass attitude. you're making yourself look like a moron.

 

too late.....

 

this is one of those threads that just makes me smile

 

how do you double clutch while shifting? basically you don't release the clutch all the way? so which one is right? powershifting or not? i only know that if you don't know how to powershift, you'll be messing up your clutch bigtime.

 

POWERSHIFTING IS BAD FOR YOUR CAR!!!! It does absolutely nothing with our cars, expecially because our peak horsepower is created so close to redline, all you would do is bounce off of the rev limiter!!!

 

A powershift, if properly done, will cause the clutch to slip. It is done on turbocharged cars to keep boost up while changing gears. When done on low-horsepower, small-powerband engines (like ours), it just causes the engine to bog because the engine cannot overcome the clutch except during a 1-2 shift. If you powershift, pay attention to the way the engine gathers itself after you let the clutch all the way back in. Chances are, it will waver around the initial RPM point of the gear you changed into before continuing to accelerate.

The best way I've found to shift in our cars is to have your arm follow the motion of your left foot on the clutch and your right foot the opposite. I.E., start rowing as soon as you begin to depress the clutch so you are in gear as soon as the clutch is depressed all the way, and the gas pedal should be all the way out at this point. Then switch the position of the gas and clutch. (That sounds much more complicated than it is) I can usually get half-second or quicker shifts this way and there's no worrying about bogging.

in other words, just shift very very quickly, no trick shit

 

how do you double clutch, and should i do it when im down shifting, at high rpms and/or low rpms?

 

ahahhahahahahaahahahahahahaahha

 

I do that when i had my Civic Si.....i call it full throttle shifting...i was watching speed vision one time and that's what they call it too...u have to do it real quick or u slipe...that's a reason some people dont do it....u only tap the clutch like a inch only. Its faster and better for ur car cuz u dont have that pull back from holding the clutch and letting the rpm drop. u just get a constant pull forward. JMO

 

you dont need to double clutch, that is meant for old manual cars, in most modern cars the tranies have syncros that match the rpm of the gears in the transmission, sometime you will notice when shifting from 4th to 1st or 2nd that the shifter feels its locked out and wont go in, thats because the gears in the tranny arent spinning at a speed where they can engage, to get around this you can double clutch, for example shifting from 3rd to 2nd you stop in neutral, tap the gas while the clutch is engaged then press the clutch and shift down to 2nd, that will make a smooth transition sometimes when the rpm are way out of range.... but this is unlikely that you will need to do this

 

oh and as for taking your foot of the gas when you shift, you DO NOT need to remove your foot from the gas when shifting your car, you just can not be accelerating at all, keep your foot on the petal so that you can keep it there with no force and the rpm will stay where is is while you shift, then as you release the clutch you can ease on the gas a little and catch the rpm as it falls into the next gear

 

also because when you do this the rpms dont fall as fast you can do what ib_jimmy said and only press the clutch in a little bit and the shifter will pop right out of gear and if u shift quickly u can get it into the next gear but you have to be quick and smooth

 

First off use the button

Second double clutching or atleast rev matching is needed in any racing besides 1/4 mile. And all of you feel free to power shift or what ever you want to call it, but be prepared to have your clutch last 1/4 the life of everyone elses, just for that alleged .01 second you gain in the quarter mile.

 

yes indeed sir! Even if you would gain that .01 (which we have pretty well decided you wont) would it be worth burning your clutch? Because it does do that.

 

who even uses the clutch these days ... i just mash it into gear

 

yeah I swapped out my shifter for half a straw, cuts shifting completely out. just flick the straw and it shifts anyway you want it too. Try it sometime, when you're trying to be a real luncher.

 

Double clutching is only useful on cars without syncros or with singles. With duals, double clutching is pointless.

 

thankyou!!!

and rev matching is just proper driving, it has nothing to do with racing

 

Thankyou auto tranny for doing all the work for me

 

hahaha automatic represent.

 

fuck automatics and your 3.0 engine

 

j/k

 

ba...

bah...



BAHAHAHAHAAHAHAHAHAHAHA




:noob:

 

I missed driving a 5 speed.....i wanna do my 6speed conversion soo bad!

 

see if u gonna down shift its better if u hold the clutch in and spear a sec to rev up ur motor then drop the clutch. this way ur car doesn't pull back..that right there is what fuck up clutch and tranny....if u rev it up and dump it....u'll just pull forward.

 

 

really? I do that all the time to slow down....

that hurts the tranny? I thought it just hurt the clutch... or flywheel or something like that, but not the tranny.

 

my friend double clutches,,,but he's practice it for months. Of course he needed a new clutch, but fucking eh, every time i race him, i'm beating him all untill he double clutches that shit. For some reason, he just gains on my ass like nothing when he does it.

 

This is a funny thread. I have spent a long time at the track and i have the trophies to prove it (only in the midwest, you so-cal racers could probably show me some fun). The powershifting thing, yeah, don't do it you won't gain anything but a repair bill. Double clutching is only for downshifts, i used to use it in my GSR all the time on slow corners when you have to downshift to above 7000rpm.

on a rant...
I used to drag that GSR all day long at red-rock in St-Paul (perhaps you guys heard about the bust with 15 cop cars and two helicopters, my car doing about 135 down the lane when the heli's came!) Point is, i tried everything, just row through the gears as fast as you can, if you even have enough time to think about matching RPM's or whatnot THEN YOUR CAR IS TOO SLOW for any kind of shifting to matter. When I dragged my teggy it would be at 8000 before i could do anything but drag the stick down.
