yes thats true... i don't understand how stupid people are... powershifting... u dont lost to many rpm but you can kill the gearbox with that fucking shit... und das ganze auf deutsch... powershifting is beschissen der Vorteil ist zwar das man weniger Drehzahl verliert (klar Kupplung öffnet das zusätzlich noch gas weg verliert man leistung und die Drehzahl sinkt im nächsten Gang) aber dadurch leidet das Getriebe und man kann echt viel Scheiße mit machen zudem isn Getriebe samt anderer Teile richtig teuer und aufwändig wenn man das alte reparieren möchte sofern das noch möglich ist
I disagree, man. I drive manuals ever since I got my driver's license and I don't see how powershifting saves time, since you can release and go back on the throttle at the same time you press and let go of the clutch.
Power shifting can deliver slightly more power to the wheels. If your clutch is tight and you spend as little time possible in between gears, its fine for racing.
Shifting fast hurts nothing, I've logged 100k miles on stock transmissions "quick shifting'' pretty regularly with no problems ..... Power shifting DOES, on the other hand, indeed DESTROY stuff.
Donovan T. In this car the revs haven’t even dropped from 8k quickshifting, it’s still shocking the gearbox and most importantly clutch... it’s just what happens
quick shifting is not possible with every car(depends on the transmission) power shifting is invented by guys who dont know how a clutch works and just destroy the flywheel at the same time (nice blue colour if you take out the transmission) yes you win some time and stay a bit higher in revs but still it will be expensive later on
Find a stay at home mechanic and it's not too bad. Cost me $300 to get my clutch replaced and that includes the price of a new clutch lol. Local shops quoted me $685-$1200
There is absolutely no reason to powershift in a N/A car. The reason people do it is to keep the turbo spooled between shifts. All your doing in an N/A car is furthering the belief you are a ricer.
***** I have no idea what you're talking about. Why are you talking to me about powerbands? Does flatfoot shifting result in the engine being at a higher rpm once you've shifted in the next gear? No, you'll end up at the same rpm as you would shifting normally therefore you'll be in the same area of the powerband. There is one reason and one reason only for flat shifting. You keep the turbo spooled and that's it. I would advise you to go and buy a boosted car, sit in neutral and give it a rev and tell me whether or not your turbo spools up.
***** no it doesn't stops dead but it stops forcing air into the engine while the bov releases the compressed air in side of the pipe, which would starve the motor, creating vacuum in the pipe for a split second which is called "boost lag"... He's right about power shifting. Its really only efective to keep the turbo spooled to prevent the lost power from lag
Power shifts are stupid. I can shift faster with a "quick shift" than a car can catch up with a "power shift." All your doing when your power shifting is slowly tearing your clutch up. A clutch works something like disk brakes just opposite operation. What I mean by "works opposite is brakes clamp to slow you down, a clutch clamps to speed you up. What you stomp the clutch to the floor without letting off the throttle is like putting on the brakes gently with the throttle still on. All your doing is making two surfaces touch in ways they are not really suppose to. A metal disk and a fiber metal in both cases are rubbing and slowly tearing down the fiber disk faster but still the metal disk also. Just shift fast and practice on shifting fast and in no time you will be able to shift faster than a person that is using "speed shifting" and having the car catch up from the lag.
Capp2015 so is the ground you walk on but it wears much faster with metal cleats. Power shifting is for people who cant drive. If you have to power shift your car...they make automatics for people like that.
The owners manual for my 1990 Honda CRX Si, which I purchased in 1991 and still drive as my daily driver, specifically states not to "speed shift" but to give the synchronizers time to work. So I've never shifted like demonstrated in the video and I'm still driving with the original gearbox internals. :-)
ijustinw I simply do not slam the shift lever into the next gear. I can actually feel the synchronization occurring through the lever. It's like this: When you shift, you'll feel a resistance in the lever after you pass "neutral" like a physical notch before the actual end of the lever travel during a shift. That "notch" is the synchronizer and it's important to not rush shifting through that notch. If you just rest the lever against the notch while shifting, it will eventually just fall into gear easily when things are synchronized. It's more noticeable when shifting at high RPM when the RPM mismatch between gears is greater thus putting more load on the synchronizers; not as much at low RPM. More effort/force against the notch creates a faster synchronization (if the synchros can handle it) with "speed" shifting being the extreme case. But like brakes, the harder/faster you shift, the faster it will wear out. On a new gearbox, the synchros are so new that the notch may not be really noticeable and shifts are easy and fast with little resistance or notch. But things will get more notchy as the synchros age and lose effectiveness, especially if "speed" shifting is a normal occurrence. Eventually you get grinding when shifting due to the synchros being too worn to work properly. But shifting gently as described above slows down this wear considerably. My 24 year old CRX above will not shift quite as quickly as when new. It takes just a tiny bit more time for the lever to "fall" into gear than when it was new. But the gearbox's internals are still original and it will not grind when shifting even at high RPM unless I force the lever through the notch faster than the synchros can work. Transmission oil also plays a role in synchro performance. Some oils allow smoother, easier shifting than others. Proper double clutching of up or down shifts is "self-synchronizing" and also prolongs synchros to insane amounts, but that's not practical for many if not most drivers. I used to do all the time which I'm sure has led to my gearbox longevity. I still do it when I want to do a fast downshift at high RPM. It's simply kinder to the synchros. Does that make sense?
pgong this actually was very informative and helpful. I have one question, today when I was waiting for someone, car turned off, I played a little bit with the gear shifter, I went over gears 1 to 2, 3 to 4 and so very fast. Did I make any damage to the synchros?
ijustinw No. Because the engine was off, nothing was spinning inside of the gearbox so no damage can happen. If the the "teeth" on the synchros and collars were not lined up, the lever might not go into gear fully but no problem. The same is true with the engine on and the clutch fully depressed.
ijustinw It should also be said that synchros are designed to be used assuming they're not abused. I don't ever recommend that anyone double clutch their shifts on a synchromesh gearbox per se, but wouldn't ever discourage it either. Shifting normally (single clutch) is normal, designed use. Double clutch shifting is being especially kind to the transmission and synchros and there's nothing wrong with prolonging the life of any machine. Plus, I can actually downshift, when at high RPM, faster with a double clutch so there is a performance advantage for me then.
The synchros in my poor little renault clio would explode if i tried to change gear that quick. Honestly the 1.2 clios have some of the worst and notchiest gearboxes in human history...still better than PRND though
+Paul Hojda Is it a Clio 2? Drove my Friend's Clio 2 very briefly and i felt what you described. I however remember driving my uncle's 94 Clio like 12 years ago and quick shifting wasn't a problem. A fun little car for how slow it actually was lol.
In general, speed shifting is pretty much like how you would shift normally, you're just doing it as fast as possible. Powershifting is when you keep the gas pedal floored and physically pull the transmission out of gear and quickly force it into the next gear. Usually you have to tap the clutch pedal, thus partly unloading the drive train from the engine's torque. This can be very hard on your car, especially if you have alot of horsepower. If done correctly it almost sounds like an automatic.
I have a Civic Si and I’m pretty glad Hondata did this, they basically let you power shift but when you push down the clutch, the ecu locks the rpm from when you pushed in the clutch, I have some videos of me doing it
Only a couple reasons to power shift I can think of: 1. You have massive turbo lag and no anti-lag system 2. You have bad gear ratios/power band and it bogs in one of the gears. The RPMs are gonna drop on the next upshift so why fight it?
Andrei Vlad I guess it would be if you're racing for pinks. Power shifting should be more clutch wear than anything, though you probably are pounding the synchros pretty hard.
davetek490 Expensive Racing Clutches are build for power shifting, if you drop the rpm lower than the matching rpm it can really hurt the flywheels and engine, because this clutches are build to handle and grip (at least)4x the torque a racing car can produce That's at least what i heard over the years^^
quick shifting isn't bad for your clutch at all. assuming you do it properly. yes, it might wear it a little faster than taking your time between gears, but it's negelable compared to powershifting.
Ik this is years later but for anyone wondering the clutch didn't engage faster or anything, u actually hear it slip slightly when power shifting... his quick shifts are crisp tho
I love the transmission on the rsx's, I drove one and it feels like it wants to go to next gear when upshifting, and its real easy to downshift too, the 1-2 shift and 2-3 shift are very smooth that it makes it almost impossible to miss shift even at high RPMs, now imagine if you had a short throw shifter would be even quicker
Powershifting most likely is faster since the throttle is open 100% all the time you shift which means maximum power all the time. Yes even though quick shifting is pretty fast you still let off the throttle so at one point your engine is not making full power. Even though these could be like 0.01 scale differences if you look at the time it took to change each gear and then add them up you will see that powershifting is faster, but at a massive cost of durabillity
powershifting is just for cars with a turbo because u lose the power u need of a turbo in a drag race if u don't stay on the throttle while shifting... in my opinion powershifting is just for cars with a turbo in a dragrace.
Marshall Morton I agree with that general concept, however this is just not true in all terms. Most nowadays turbo reach there high end line way bore the end of the ref limiter. Only a few cars have linear power lines. So this really doesn't matter. Some cars you can even go back to 4000 rpm and still have max power from the spool instead of going to the 7000'ish... And what I am saying is even more true with twin scroll turbos.
***** Whenever you get off gas on a turbo car the airflow will drop thus not "driving" the turbo...it loses inertia as well. Keeping on throttle mitigates this...at least to the best of my understanding. And no one said anything about rev limiters...why even bring it up? Some philosopher once said: Best to be considered an idiot than open mouth and remove all doubt!
Steve Smythe You sir, have won the crown... You obviously didn't read my comment. This whole video was made to show that if you don't ship fast enough you might lose ''Power''. This is bullshit in most cars! And that is why I talked about the rev limiter. If you go on a dyno you will see the power curve. Most cars, and I bet most of the people here have a power curve that will be constant at around 4000 to 7000 so it really does not matter how you shift. As long as you are above those 4000 your turbo will create it max possible HP. You will never go faster then that. FACT!
power shifting trashes gear synchro's which is the reason I got my s10 so cheap previous owner power shifted while hauling struff with trailer synchros in 4th are gone with reverse and 2nd on there way out. basically just use the damn clutch because it is cheaper than a transmission.
forgot to add replacing transmission I am not driving it like this not even mobile because the clutch looked like shredded jerky guy couldn't drive stick currently fixing it.
Not bad but you don't have to fully depress the clutch pedal when doing this. This will increase your speed further. I can tell he is by the gain in rpm between gears. I started out in a Datsun 280zx w/5 speed and now have a Camaro w/6 speed. Those t-56 6 speeds are much harder to gate than most.
despite the rice, this is actually a good video. Not that many people know what power shifting really is, and the guy here can actually shift really well
@TCreatorO Type rsx misshift on youtube and you'll see what happens when you put it in the wrong gear... a mistake that may cost quite alot to repair ! As for confidence, well it comes with time and practice, like any other activity. When I shift like that, I don't think about it twice. I just kick the clutch hard and slam the shifter into gear, not caring about what could happen if it doesn't go in. If you hesitate, chances are that you will miss the shift.
My only concern with these shifting styles are that I don't want to visit the auto repair centre the next day asking to have my clutch / gearbox replaced lol.
(clears throat) But as Alex from Car Throttle said: "If you abuse the Multipla like that it will punish you back. For example, if you shift it quickly, in the next second you will see the gear stick pop out of the gearbox."
you mean downshifting to get into the powerband on the fly? Blip the throttle (take into account your throttle respone and adjust your timing accordingly), when blipping, do it heavily, don't kiss the throttle, press it completely and realease it quickly, as you do so, step into the clutch and precisely yank the shifter into the gear you want to go into. Do it in this order so that the engine will rev suddenly and the synchros won't have to work so hard, the shifter will move easier.
I hate that crunching sound when you shift. I'm reading down the comments and there seems to be a better way called synchronizing shifts. Sounds like you wouldn't be hurting her if you tried that technique.
+Marvy Marv I usually rev it all the way to the red line then slam it into the next gear without any clutch. it makes a huge grinding sounds and smoke comes out the floor board but i get an extra .02 at the local parking lot.
I have a stock Acura Rsx Type S 05, I've gone close to 150 down hill so cal so 120 ain't a big deal although this guy "power shifting" is going to fuck up his gear box
Lol I don't know what you're thinking but the K20Z1 at 212 Hp isn't a little joke. Even if you go on here you will see Rsx -s hitting 145 running 6.5 rpm, or do you want to see that same engine K20Z1 @1200 HP, 1/4 Mile 7.8 hitting 186, with turbo, cams, cold air, dog box tranny? And that's without shooting nitro. That's my mechanics set up and exact same engine as mine I'd like to hear your engine pull that off. (Although in the bad side he did fuck his engine in Vegas in December drag racing dog box tranny caught 1st instead of going 3rd blew his engine)
Power shift is just driving wrong dude, you are fucking your clutch.... Btw, i never uderstood how to properly downshift on a stick... I mean, when i do it with my car, the car makes a punch, i mean, like if it stalls, (it doesnt) but idk it sounds and looks weird... How do i know at what speed should i change the gear down without passing the redline and fucking everything? I do know that i can do 0-40 in first, 40-90 in second, 90-130 in third, 130-150 in fourth and 150-180 in fifth... (Km/h) Sadly i have a 120 hp car haha
powershifting is used by people who race hence the name power shifting makes you go a little quicker at the cost of more wear on ur transmission doing it all the time is dumb but if you wanna race its pretty reasonable
Slow down before down shifting the reason you feel a punch is because the engine is taking the punch by slowing down your vehicle. To downshift slow the car down first maybe to between 1500 to 2000RPM Another thing could be rev matching many tutorials out there. Always match the engine with the transmission.
So when ur engine is going too hard for the current speed your clutch is spinning, it yanks the car forward when the clutch connects to the fly wheel... except it's not just connecting when u do it, it's getting slammed together when there not even close to matching. Sounds to me like u really hate ur clutch. I'm sure it hates you too
Had to put my 2 cents in.I'm old as dust and grew up in the muscle car era.Won many a street race because of good power shifting. Automatics have come a long way but nothing is like a manual if you can drive it and this guy can.
And if you read the entire comment you would have noticed I said, "Usually you have to tap the clutch pedal, thus partly unloading the drive train from the engine's torque." To answer your question: This was done on a 69 Camaro with a 500HP L88, an M22 with a short throw Hurst shifter, solid lifters, 4:88 gears, no rev limiter, big forearms, and maybe a little luck back before trans breaks and huge stalls.
I wish Miata transmissions were awesome enough to do this. Not even an unsprung clutch disk will let you get through a gearshift that fast. Maybe I need a Honda transmission... Sounds good btw.
he's right cars usually 11sec or quicker the majority of the time you will ONLY see automatics, because the difference a car loses when letting off the gas is greater than
With automatics, their performance is going to vary a lot. Most people today discount automatics as a performance option, because most cars today are tuned for economy and smoothness. But the old school autos from the '60s tended to aim for performance, so you got shifts matched to your power curve, and much faster shifts. Full-manual valve bodies also exist, so that the transmission stays in whatever gear you tell it, except you still get the torque converter and all its goodness.
If power shifting is NOT lifting off the gas as you said, so why do we not hear the engine reving up a bit when you shift? I don't think you are doing it right..........
lemme explain some things, power shifting may damage your car but at some cars it can save you time on the quarter mile or straightways, it is only helpful when you drive a turbocharged car so that in between shifts boost won't go down as much as it normally does (power shifting is useless in naturally aspirated engines). Don't wanna kill your clutch? then kill your turbo with an anti lag system.
Simple: Automatic is designed for ease of use and efficiency. It keeps the engine and low revs most of the time which means you use less petrol, however, manual shifting means that you can keep the car at high revs. The max amount of power from the engine comes at the upper range of revs, and thus it means that in a manual you will have more control of when you have max amount of power. I'm not sure about drag racing though, it seems that a tuned-auto gearbox and manual power shifting are equal.
quick shifting means pulling the gear out without depressing the clutch in the moment when u letting of the gas and only pressing the clutch when u are about to throw into next gear...
Sure, to shave a couple tenths off, but you'll be replacing your transmission every 5 runs before the metals chunks start slowing you down more than the powershifting speeds you up.
I have been driving a manual transmission for years. I recently bought a new honda si and have been looking at videos online like crazy. I learned on my own and have never really utilized downshifting. It is a new concept to me. So far, to my understanding , it is bad to coast on neutral at a high speed into a complete stop. Is this something most of you here would agree on? And if so, why?
Coasting at high speed in neutral isnt bad, people would say coasting in neutral is bad and danger because they dont know much....slowing do while in gear or engine braking actually put some stress on your engine, you could say you eats your engine everytime you doing it...thats why drag racer will always coasting in neutral after finish, because they trying to last their engine....it does burn more brake pads but it doesnt really hurt..
Joel Davila another reason for downshifting is if you need to get out of the way of something you can kick the gas and get out of its way, if you're in neutral there's no way to accelerate if there happens to be a problem. Even if I'm not using engine braking, I hold the clutch and go down the gears as my speed comes down so if there is a problem I can let off the clutch and be in the right gear.
Power shifting is strictly for drag racing. It's not stupid. It's a drag racing shifting technique. You don't see pro stock motorcycles or ps cars disengaging the engine.
I never said they were. But trans breaks and huge stalls in automatic transmissions are most often used today in place of manual transmissions at that level of drag racing because back then automatics weren't like what we have today. If you'd ever even been to a dragstrip and raced a car you'd know that already. Any more questions, kido?
Hi there. I'm not a woman ;) I have a BMW with automatic transmissoin from GM and it works like a charm. I guess I wasn't clear enough. All I ment was, that this is not useful daily, because it's stressing the transmission, but it' is a very good demonstration of skill. Peace.
I learned manual on old transmissions made before the car would help you shift. Had to wait for rpms to drop before shifting for a smooth, non-damaging shift (which takes way longer than it does for tuners). It hurts to see shifting done this way :'(
As an avid drag racer, my observation of powershifting is that it's something done by kids who think they're going to beat me by redlining and ruining their transmission. People that don't have mommy and daddy to pay for a new clutch assembly or transmission generally don't do that unless they drag race on a forced induction motor and have invested a lot of time and money into beefing up their clutch and tranny. My Ford Performance TKO 600 is rated at 'extra heavy duty', mated to a B&M shifter and a Centerforce clutch, and yet I still don't see any gains from powershifting or floating the gears. My advice is to take your car to the track, and compare your lap times between powershifting and normal, quick shifting and see if there's any difference. If you're one of the very tiny percentage of people that see an increase in performance from powershifting, then start throwing money at your car because you're going to burn up a lot of gears and clutches figuring out how to do it correctly.
Power shifting is terrible, you can tell that from the unpleasant jerks during power shifting, these jerks are the transmission absorbing the impact of the poorly synchronized revs. Plus, you may even lose grip if the jerk is too violent.
I am no speed driver, just a regular city driver with manual experience. Daily driving focuses on smoothness to make the passengers comfortable, and I've heard that smoothness is also important in racing because violent jerks may upset the car. You may lose grip in a corner.
This dude is like a human DCT

Holy crap you're right

+ryvoltz yep I can smell the clutch pad burning
yes thats true... i don't understand how stupid people are... powershifting... u dont lost to many rpm but you can kill the gearbox with that fucking shit...
und das ganze auf deutsch... powershifting is beschissen der Vorteil ist zwar das man weniger Drehzahl verliert (klar Kupplung öffnet das zusätzlich noch gas weg verliert man leistung und die Drehzahl sinkt im nächsten Gang) aber dadurch leidet das Getriebe und man kann echt viel Scheiße mit machen zudem isn Getriebe samt anderer Teile richtig teuer und aufwändig wenn man das alte reparieren möchte sofern das noch möglich ist
In case of a drag race, that technique is a good way to cut some decimals if you can't keep up the car next to you.
I disagree, man. I drive manuals ever since I got my driver's license and I don't see how powershifting saves time, since you can release and go back on the throttle at the same time you press and let go of the clutch.
Power shifting can deliver slightly more power to the wheels. If your clutch is tight and you spend as little time possible in between gears, its fine for racing.

Plus, I can actually downshift, when at high RPM, faster with a double clutch so there is a performance advantage for me then.
The synchros in my poor little renault clio would explode if i tried to change gear that quick. Honestly the 1.2 clios have some of the worst and notchiest gearboxes in human history...still better than PRND though
Paul Hojda Really? I drive a 1.2 myself and I can slam the gears in. Although I usually do not do this because it hurts...:D
+Paul Hojda Is it a Clio 2? Drove my Friend's Clio 2 very briefly and i felt what you described. I however remember driving my uncle's 94 Clio like 12 years ago and quick shifting wasn't a problem. A fun little car for how slow it actually was lol.
French cars are shitty
Powershifting is for drag racing
Quick shifts is for drag racing
In general, speed shifting is pretty much like how you would shift normally, you're just doing it as fast as possible. Powershifting is when you keep the gas pedal floored and physically pull the transmission out of gear and quickly force it into the next gear. Usually you have to tap the clutch pedal, thus partly unloading the drive train from the engine's torque. This can be very hard on your car, especially if you have alot of horsepower. If done correctly it almost sounds like an automatic.
Good for you. Glad to see someone working in their shifting skills for once.
i love how it struggles to get to 100km/h lol
As bad as powershifting may be, you pull them off so seamlessly! Most enthusiasts wouldn't be able to tell you weren't lifting!
I have a Civic Si and I’m pretty glad Hondata did this, they basically let you power shift but when you push down the clutch, the ecu locks the rpm from when you pushed in the clutch, I have some videos of me doing it
Lmfao the quick shifting killed me for some reason i cant stop laughing
My man shifting, driving and filming all at the same time
Only a couple reasons to power shift I can think of:
1. You have massive turbo lag and no anti-lag system
2. You have bad gear ratios/power band and it bogs in one of the gears.
The RPMs are gonna drop on the next upshift so why fight it?
actually power shifting is about half a car length difference between normal shifting and power shifting
iLLinFiniTiG35
Assuming your clutch hooks up properly. And you don't spin the tires.
davetek490 That's not a reason to trash your transmission.
Andrei Vlad I guess it would be if you're racing for pinks.
Power shifting should be more clutch wear than anything, though you probably are pounding the synchros pretty hard.
davetek490 Expensive Racing Clutches are build for power shifting, if you drop the rpm lower than the matching rpm it can really hurt the flywheels and engine, because this clutches are build to handle and grip (at least)4x the torque a racing car can produce
That's at least what i heard over the years^^
That left hand tho. lol
Quick shifting? It's just called shifting lol
but quickly
yepp! with the ill will to destroy your clutch!
quick shifting isn't bad for your clutch at all. assuming you do it properly. yes, it might wear it a little faster than taking your time between gears, but it's negelable compared to powershifting.
You have fucked up synchros don’t you lol
OMG STOP IT. I cant stop cringing, OMG THE CLUTCH, THE TRANSMISSION. OMGGG
Ik this is years later but for anyone wondering the clutch didn't engage faster or anything, u actually hear it slip slightly when power shifting... his quick shifts are crisp tho
Wow. Nobody reads descriptions anymore, do they?
they're too lazy
+Masayoshi "this is so stupid..."
I love the transmission on the rsx's, I drove one and it feels like it wants to go to next gear when upshifting, and its real easy to downshift too, the 1-2 shift and 2-3 shift are very smooth that it makes it almost impossible to miss shift even at high RPMs, now imagine if you had a short throw shifter would be even quicker
Cool name
Powershifting most likely is faster since the throttle is open 100% all the time you shift which means maximum power all the time. Yes even though quick shifting is pretty fast you still let off the throttle so at one point your engine is not making full power. Even though these could be like 0.01 scale differences if you look at the time it took to change each gear and then add them up you will see that powershifting is faster, but at a massive cost of durabillity
I've destroyed many transmissions powershifting. And I'd do it all over again. Getting it "right" is very satisfying.
powershifting is just for cars with a turbo because u lose the power u need of a turbo in a drag race if u don't stay on the throttle while shifting...
in my opinion powershifting is just for cars with a turbo in a dragrace.
Ahmo Bandolero Please explain how the turbo loses power?
+Paul theuns the turbo will unspool when you get off power, so it has to respool a little bit if you are quick shifting.
Marshall Morton I agree with that general concept, however this is just not true in all terms. Most nowadays turbo reach there high end line way bore the end of the ref limiter. Only a few cars have linear power lines. So this really doesn't matter. Some cars you can even go back to 4000 rpm and still have max power from the spool instead of going to the 7000'ish... And what I am saying is even more true with twin scroll turbos.
***** Whenever you get off gas on a turbo car the airflow will drop thus not "driving" the turbo...it loses inertia as well. Keeping on throttle mitigates this...at least to the best of my understanding. And no one said anything about rev limiters...why even bring it up? Some philosopher once said: Best to be considered an idiot than open mouth and remove all doubt!
Steve Smythe You sir, have won the crown... You obviously didn't read my comment. This whole video was made to show that if you don't ship fast enough you might lose ''Power''. This is bullshit in most cars! And that is why I talked about the rev limiter. If you go on a dyno you will see the power curve. Most cars, and I bet most of the people here have a power curve that will be constant at around 4000 to 7000 so it really does not matter how you shift. As long as you are above those 4000 your turbo will create it max possible HP. You will never go faster then that. FACT!
power shifting trashes gear synchro's which is the reason I got my s10 so cheap previous owner power shifted while hauling struff with trailer synchros in 4th are gone with reverse and 2nd on there way out. basically just use the damn clutch because it is cheaper than a transmission.
forgot to add replacing transmission I am not driving it like this not even mobile because the clutch looked like shredded jerky guy couldn't drive stick currently fixing it.
It trashes your synchro's... what? (What thing or things belonging to a synchro did you mean to be referring to but left out?)
Wow, a video of a Honda NOT money shifting. Nice work!
smart and easy move - just film it outside to understand how fast this shift
Not bad but you don't have to fully depress the clutch pedal when doing this. This will increase your speed further. I can tell he is by the gain in rpm between gears. I started out in a Datsun 280zx w/5 speed and now have a Camaro w/6 speed. Those t-56 6 speeds are much harder to gate than most.
Great shifting man, almost sounds like an auto lol!
i didnt realize how cool u look with your hand at 12 o clock like they teach u in driving school
despite the rice, this is actually a good video. Not that many people know what power shifting really is, and the guy here can actually shift really well
@TCreatorO Type rsx misshift on youtube and you'll see what happens when you put it in the wrong gear... a mistake that may cost quite alot to repair !
As for confidence, well it comes with time and practice, like any other activity. When I shift like that, I don't think about it twice. I just kick the clutch hard and slam the shifter into gear, not caring about what could happen if it doesn't go in. If you hesitate, chances are that you will miss the shift.
i do both of this in my saxo
Gonna try this in my Jeep Compass! Thanks!
@plefrancois perfect shifting sounds! BTW, during the quick shifting, will you lift the right foot completely or just partially?
Or learn to drive a stick with a 18 speed Eaton then get in these little 6 speeds
It sounds nothing like a Subaru lmao +Craig Reeves good one troll
Congrats you now have an automatic you shifted so fast.
My only concern with these shifting styles are that I don't want to visit the auto repair centre the next day asking to have my clutch / gearbox replaced lol.
R Ahmed and flyweel
Can I do this in a Fiat Multipla?
yes!
(clears throat) But as Alex from Car Throttle said: "If you abuse the Multipla like that it will punish you back. For example, if you shift it quickly, in the next second you will see the gear stick pop out of the gearbox."
Or buy a car that has No Lift shirting previsions.
[ECU keeps revves at red-line between shifts]
They have that??
BunnyBUNGALO Lotta factory cars have it now.
Stephen Bagnell its called over rev and its a negative aspect of drive by wire systems. It can be tuned out.
nizmojoeblows
What ?
nizmojoeblows So over rev is different than rev matching feature? Please explain the difference. I want to know :D
finally someone on youtube that knows what their talking about.
you mean downshifting to get into the powerband on the fly? Blip the throttle (take into account your throttle respone and adjust your timing accordingly), when blipping, do it heavily, don't kiss the throttle, press it completely and realease it quickly, as you do so, step into the clutch and precisely yank the shifter into the gear you want to go into. Do it in this order so that the engine will rev suddenly and the synchros won't have to work so hard, the shifter will move easier.
Good way to destroy gearbox and clutch. ......thanks for the tip.
yes powerlifting is good. nice biceps.
Loved the VTEC kick.
this is really an awesome video! your shift is really good and fast! please make more videos like this :)
Maybe should learn how to hold the steering wheel correctly...
I hate that crunching sound when you shift. I'm reading down the comments and there seems to be a better way called synchronizing shifts. Sounds like you wouldn't be hurting her if you tried that technique.
Just grinding down the gears. No big deal.
+Marvy Marv I usually rev it all the way to the red line then slam it into the next gear without any clutch. it makes a huge grinding sounds and smoke comes out the floor board but i get an extra .02 at the local parking lot.
that’s just limiter lol
Sounds ballsy. Love the induction sound of vtec.
Great shifting period! Great gear box too! Just a fan of all motors
LOL at the acura.. top of 5th and hes going like 80 lmfao...honda power baby
Lol top 5th is closer to 120 more than anything 6th is pushing 145 stock on type s
Julian Avila 0:30. i doubt it can even hit 120 mph
I have a stock Acura Rsx Type S 05, I've gone close to 150 down hill so cal so 120 ain't a big deal although this guy "power shifting" is going to fuck up his gear box
Julian Avila I really doubt it lol sorry. a shitbox honda 4banger non turbo going 150? no way mate
Lol I don't know what you're thinking but the K20Z1 at 212 Hp isn't a little joke. Even if you go on here you will see Rsx -s hitting 145 running 6.5 rpm, or do you want to see that same engine K20Z1 @1200 HP, 1/4 Mile 7.8 hitting 186, with turbo, cams, cold air, dog box tranny? And that's without shooting nitro. That's my mechanics set up and exact same engine as mine I'd like to hear your engine pull that off. (Although in the bad side he did fuck his engine in Vegas in December drag racing dog box tranny caught 1st instead of going 3rd blew his engine)
Power shift is just driving wrong dude, you are fucking your clutch.... Btw, i never uderstood how to properly downshift on a stick... I mean, when i do it with my car, the car makes a punch, i mean, like if it stalls, (it doesnt) but idk it sounds and looks weird... How do i know at what speed should i change the gear down without passing the redline and fucking everything? I do know that i can do 0-40 in first, 40-90 in second, 90-130 in third, 130-150 in fourth and 150-180 in fifth... (Km/h) Sadly i have a 120 hp car haha
learn to rev match and you'll make downshifting much easier.
powershifting is used by people who race hence the name power shifting makes you go a little quicker at the cost of more wear on ur transmission doing it all the time is dumb but if you wanna race its pretty reasonable
Slow down before down shifting the reason you feel a punch is because the engine is taking the punch by slowing down your vehicle.
To downshift slow the car down first maybe to between 1500 to 2000RPM Another thing could be rev matching many tutorials out there. Always match the engine with the transmission.
lol wut I only know like two people who power shift. That wear accumulates. Wear is definitely not worth the extra .0005 seconds down the road.
granny shiftin not double clutchin like youre supposed to
Can i learn to shift like you when im older ^.^
All I know is that everytime I shift I hear a big tssss!!! ;)
Still slow as hell
loud as fuck but doesn't go anywhere in a hurry. bit like my ex.
So when ur engine is going too hard for the current speed your clutch is spinning, it yanks the car forward when the clutch connects to the fly wheel... except it's not just connecting when u do it, it's getting slammed together when there not even close to matching. Sounds to me like u really hate ur clutch. I'm sure it hates you too
This video should be called, Im a ricer in Honda who thinks destroying my transmission makes me faster lmao
Had to put my 2 cents in.I'm old as dust and grew up in the muscle car era.Won many a street race because of good power shifting. Automatics have come a long way but nothing is like a manual if you can drive it and this guy can.
Nice shifting , very quick. Good work
Damn you've got a racer's left foot. Fast as hell
wow it sounds like a dual clutch transmission you're shifting so fast. how long have you been driving stick?
And if you read the entire comment you would have noticed I said, "Usually you have to tap the clutch pedal, thus partly unloading the drive train from the engine's torque."
To answer your question: This was done on a 69 Camaro with a 500HP L88, an M22 with a short throw Hurst shifter, solid lifters, 4:88 gears, no rev limiter, big forearms, and maybe a little luck back before trans breaks and huge stalls.
I give his mom props for driving standard.
You are 100% correct, and I do believe its the type-s.
I wish Miata transmissions were awesome enough to do this. Not even an unsprung clutch disk will let you get through a gearshift that fast. Maybe I need a Honda transmission... Sounds good btw.
he's right cars usually 11sec or quicker the majority of the time you will ONLY see automatics, because the difference a car loses when letting off the gas is greater than
With automatics, their performance is going to vary a lot. Most people today discount automatics as a performance option, because most cars today are tuned for economy and smoothness. But the old school autos from the '60s tended to aim for performance, so you got shifts matched to your power curve, and much faster shifts. Full-manual valve bodies also exist, so that the transmission stays in whatever gear you tell it, except you still get the torque converter and all its goodness.
The latter is called a no lift shift. If your gear box isn't built for it, you're playing with fire
If power shifting is NOT lifting off the gas as you said, so why do we not hear the engine reving up a bit when you shift? I don't think you are doing it right..........
Seems fun, when in a safe controlled environment.
Quick Shift = well, you are shifting gears quickly
Power Shift = You don't let go of the gas. The gas pedal is floored.
in my prius it has a r does that mean really quick shifting
+Steffen AMMANN its bad, the only time you should do it is when you're racing.
lemme explain some things, power shifting may damage your car but at some cars it can save you time on the quarter mile or straightways, it is only helpful when you drive a turbocharged car so that in between shifts boost won't go down as much as it normally does (power shifting is useless in naturally aspirated engines). Don't wanna kill your clutch? then kill your turbo with an anti lag system.
YOUR CAR LOOKS SO SICK AT NIGHT BRO REALLY
Simple: Automatic is designed for ease of use and efficiency. It keeps the engine and low revs most of the time which means you use less petrol, however, manual shifting means that you can keep the car at high revs. The max amount of power from the engine comes at the upper range of revs, and thus it means that in a manual you will have more control of when you have max amount of power. I'm not sure about drag racing though, it seems that a tuned-auto gearbox and manual power shifting are equal.
thats some dope ass shifting dude
quick shifting means pulling the gear out without depressing the clutch in the moment when u letting of the gas and only pressing the clutch when u are about to throw into next gear...
yea seriously dude this video is great.
awesome shifting, i want you to post more videos
Isn't powershifting helpful in drag racing? 🤔
Sure, to shave a couple tenths off, but you'll be replacing your transmission every 5 runs before the metals chunks start slowing you down more than the powershifting speeds you up.
Shifts like an automatic! That is badass!
I have been driving a manual transmission for years. I recently bought a new honda si and have been looking at videos online like crazy. I learned on my own and have never really utilized downshifting. It is a new concept to me. So far, to my understanding , it is bad to coast on neutral at a high speed into a complete stop. Is this something most of you here would agree on? And if so, why?
Coasting at high speed in neutral isnt bad, people would say coasting in neutral is bad and danger because they dont know much....slowing do while in gear or engine braking actually put some stress on your engine, you could say you eats your engine everytime you doing it...thats why drag racer will always coasting in neutral after finish, because they trying to last their engine....it does burn more brake pads but it doesnt really hurt..
Joel Davila another reason for downshifting is if you need to get out of the way of something you can kick the gas and get out of its way, if you're in neutral there's no way to accelerate if there happens to be a problem. Even if I'm not using engine braking, I hold the clutch and go down the gears as my speed comes down so if there is a problem I can let off the clutch and be in the right gear.
That fucking VTEC crossover tho 🤤🤤🤤🤤🤤🤤🤤
Power shifting is strictly for drag racing. It's not stupid. It's a drag racing shifting technique. You don't see pro stock motorcycles or ps cars disengaging the engine.
The owners manual for my CRX specifically says to NOT do this, LOL. Says something along the lines of "allow the synchros some time to work."
I never said they were. But trans breaks and huge stalls in automatic transmissions are most often used today in place of manual transmissions at that level of drag racing because back then automatics weren't like what we have today.
If you'd ever even been to a dragstrip and raced a car you'd know that already. Any more questions, kido?
that is some badass shifting! good work!
thats just awesome shifting skills dude - respect
nice bro, have u ever try both on 1/4 mile just 2 see which one is faster?
Listen to that clutch grind
Hi there. I'm not a woman ;) I have a BMW with automatic transmissoin from GM and it works like a charm. I guess I wasn't clear enough. All I ment was, that this is not useful daily, because it's stressing the transmission, but it' is a very good demonstration of skill. Peace.
I learned manual on old transmissions made before the car would help you shift. Had to wait for rpms to drop before shifting for a smooth, non-damaging shift (which takes way longer than it does for tuners). It hurts to see shifting done this way :'(
I always Quick Shift, because Power shifting shorten the life of the clutch , nice clip by the way.
These are the clutch and gearbox destroyers.
so crisp, i applaude your shifting skillz :)
As an avid drag racer, my observation of powershifting is that it's something done by kids who think they're going to beat me by redlining and ruining their transmission. People that don't have mommy and daddy to pay for a new clutch assembly or transmission generally don't do that unless they drag race on a forced induction motor and have invested a lot of time and money into beefing up their clutch and tranny. My Ford Performance TKO 600 is rated at 'extra heavy duty', mated to a B&M shifter and a Centerforce clutch, and yet I still don't see any gains from powershifting or floating the gears.
My advice is to take your car to the track, and compare your lap times between powershifting and normal, quick shifting and see if there's any difference. If you're one of the very tiny percentage of people that see an increase in performance from powershifting, then start throwing money at your car because you're going to burn up a lot of gears and clutches figuring out how to do it correctly.
Power shifting is terrible, you can tell that from the unpleasant jerks during power shifting, these jerks are the transmission absorbing the impact of the poorly synchronized revs. Plus, you may even lose grip if the jerk is too violent.
I am no speed driver, just a regular city driver with manual experience. Daily driving focuses on smoothness to make the passengers comfortable, and I've heard that smoothness is also important in racing because violent jerks may upset the car. You may lose grip in a corner.
