i was wondering how do you "power shift" when racing? and i heard its bad for your engine? is it true?

do you mean clutch less shifting. I've never done it and don't recomend it but you just bring the rpms up high(6500) and slam into the next gear without ever letting go of the gas.

Im not sure but i know this some crazy way of shifting

I'd hate to see your tranny's synchros after doing some shyt like that

IMO, what you put the tranny through is not worth the time you save in a shift like that.

ur basically shifting without taking your foot off the gas.

better make sure your a dang good driver and can shift lightning fast. usually not recommended. I've seen it done in jdm drifting videos

I've done it at the track before...just once though.

MaxedOutOfCash

i can do it never done it in a max but in a 2002 passat (not mine)
i wouldn't recommend doing it on your car

Larrio

not recommended but an interesting concept

Someone's car that needed a tranny after you began your estimate??

God Damn mechanics......

DO NOT TRY THIS YOU WILL DESTROY YOUR TRANY!!

My friend told me that each gear has a certain RPM that when it hits, it opens up and you can engage with out the clutch. But it takes practice to do this,each car is different so it takes some time to get it down if you have a trany to spare go for it.

Drjmaxx88-That is true, but it helps if your syncros are in good shape. Takes some practice to find the 'happy' spots. For the most part, a good rule of thumb is about 1000-1200rpm less than what you were at when you pulled it out of gear, of course it depends on how slow/fast you are going. One thing is to take it easy.

Shifting wihtout clutch is doable at any RPM , but the engine RPM must match the tranny RPM in which gear you wanna go in. Which can't be obtain while WOT!

Power shifting for me, is Keeping it to the floor, but shifting with clutch as fast as you can! (some practice needed)
The principe is to get the shifter out while starting to depress the clutch(not fully depress) and enter in the upper gear while fully depress. So you throw on the shifter at the same paste as you depress the clutch (depend on your shifter travel: STS= is not the same as the clutch but OEM one, almost)

1-2 shifting is the most easy one!
2-3 really hard!
3-4 almost as easy as 1-2!!

Getting out the gear (to neutral) isn't armfull for your tranny without the clutch but at WOT you must do it really quick and not go too far!

Power Shifting without any clutch depressing will kill your tranny in less time that will need you to find a garage that's gonna change it!!

Don't forget, that while shifting your engine gonna redline all the time, that's why you want to make it as quick as possible!
Your clutch gonna be arm too, cause it slip somewhat every time!!

Shifting without the clutch is a terrible idea. My Max isn't a 5-Spd, but my dad's Civic Si is. And when I go out to take it for a spin, I powershift as what Maxpat stated, shifting as fast as you can while using the clutch.

In the Civic 1-2 shift results in some nasty barkage of the tires, and I have chirped 3rd on occasions. It all comes down to how fast your left foot, and your right hand is.

I love shifting, that's why this summer a 5-spd will be going inplace of the auto!

If you have an extra tranny go for it, see how fast you can blow out the one in the car!

isnt "power shifting" or double clutching for cars 8 cylinder and higher ...
such as trucks...
thats what i heard

Maxpat82

scopium: Power shifting and double is not the same thing at all!

Larrio

iTrader: (10)

i think that only applies to double clutching cause alot of trucks don't have synchros.

i doubt the power shifting

VQdriver

shifting up without the clutch isn't recommended. however, it's possible to downshift without the clutch. slight blip to the gas unloads the gears and lets you shift into neutral. a bigger blip to match rev to the lower gear lets you downshift without grinding. gotta get the timing right. perfected, one can use left foot braking in conjuction with clutchless downshifts for economy of motion (no need for heel and toe) and the fastest way around a corner! at least in theory.

this will kill you clutch very quickly.

Id recomend doing some regular shifting and just do it realy fast.
all that fast and furious stuff messes up your car!

all this powershifting talk as if we drive around in 500hp sports cars. i guess doing a powershift is wats gonna help u beat a vette, but if it does then go for it.

got rice?

iTrader: (2)

Group buys on new 4th and 5th gear synchros!

ChrisCheezer

if u wana do some impressive shifting try the heal-toe, im so good at it in my friends Mx-6, we just drive around looking for good turns to heal-toe shift out of, alot of fun. with out risking ur tranny/clutch.

Power shifting is simply this. Keeping your foot on the gas while still using the clutch to make your shifts. That's it! You must be lightning fast with your left foot and right hand to do this well. Maxpat82 was right on the money in his explaination. I've done it in my turbo SE-R and it takes about .2 seconds of my 1/4 mile time. If you are very serious about your drag times then do it otherwise just take your foot off the gas, depress the clutch pedal and shift the damn thing as fast as you can.

It appears that everyone seems to have their own idea of what power shifting is. I doubt that any of you have cars that will allow you to jam into the next gear without touching the clutch and without matching the correct RPM. Syncronizers simply aren't strong enough to do this.
I can and have been able to shift without using the clutch in every vehicle I have tried but it takes patience and perfect timing as well as preloading the syncro.

Now my idea of power shifting or speed shifting still requires the clutch however when I am staright line racing the car i do not let off the gas, ever. I just run the engine within 50 rpm of it's rev limiter, stab the clutch, shift tot he next gear and come back off the clutch leaving the engine just barely enough time to bounce off it's rev limiter once, and sometimes not.

The only vehicle that I have driven that absolutely hates the power shift is the turbo beetle. They make a loud kerchunck noise in the drivetrain when you do this and they still cut boost going into the next gear EVEN if you have the traction control off.

flashover

I thought that heel-toe shifting is for RWD cars only.
I dont see the point in a front wheel drive.

[maxi-overdose]

iTrader: (3)

i think the idea is to keep the rpm high while cornering. so you dont lose too much rpm when you upshift.

nismos14

heel toe is for keeping the car in the power band, rather than breaking into a turn and not having peak power to pull you through the turn, u heel toe to downshift as u slow down to turn using ur heel and toe all at once
