Power shifting is just like regular shifting in a manual transmission, but you never lift your foot off the gas pedal - clutch goes in and out, while your right foot remains planted and the gear shift is executed. The problem is if you keep the gas pedal down while shifting, your engine RPM goes up, but your transmission wants a lower RPM, so this discrepancy is handled by the clutch, creating a shock load within the system. But you can design your way out of this, watch to learn more!

why do we accomodate fools? we already had flat foot shifting, it was called a shitty automatic.
Make video about clutch boosters and electronic clutch actuators etc.
That’s not how you power shift….. power shifting is when you let off the gas slam the next gear and back on the gas without using the clutch….
power shifting is shifting while feathering the throttle, you never touch the clutch. study before you make a video
No lift shift, not power shift, and this isn’t the best way to do it.
The best way to do it is to go very close to the rev limiter, clutch in and slam the shifter to the next gear, release clutch slightly slower than usual for traction(if needed). This way, nothing is really working wrong.
i have never thought power shifting was a good idea lol
Fast and furious kids... They have ideas that are like nails on chalkboards to anyone with mechanical sympathy.
It works okay if you're drag racing old American V8 hot rods, but those tend to have much heavier rotating assemblies and flywheels than modern sports cars, so the rpms don't jump up too much, at least not if you jam the shifter into the next gear quickly enough. Rev hang is still a problem, though. Your engine will still be spinning faster than your transmission's input shaft wants to go, and you'll still cause shock loading through your clutch plate(s).
@@saccaed 💯💯💯💯💯
If you have a 2 step system that can temporarily lower your rev limit, you can hook it to the clutch switch and achieve a similar effect.
@@saccaed No, they're good ideas for racing when you've got the money and knowledge to work on your car daily (because you'll have to, considering you're wearing your parts out a LOT sooner).
Wait, are you saying it's not normal to have to replace my clutch plate every six months?
Damn 😂
Depends, if you're travelling to the moon and back, you'll probably have to replace it anyway :D
Apple here: it's normal. Keep on going!
depends on if you’re racing your car or not

@@TheWITE-FOX That power shifting is better? That means people around you give proper use to their car. If you mean my joke well is the same.
@@ElTrolldeYoutubii I mean I’ve never heard of power shifting and I like your comment
Some motorcycle owners install a switch that cuts the ignition when you stomp a gear, for similar reasons. On my dirt bikes, if I'm climbing or really hauling ass, I just stomp the gear without clutching or letting off. They survived years of that.
I definitely believe you, but having worked on both I can say the mechanisms DO the same thing, but ARE not exactly the same machine design and the forces are a ⅕ of in a car because the weight is so low. Much of the shock load is from momentum/inertia too because the wheels are still turning.
2 stroke dirtbikes that are older not so much as the coils are unlimited. But on 4 strokes and modern most bikes made since 1980 you can do the same thing by preloading the shift lever well in advance. As you climb up to recline you increase pressure on the shifter and once you bang limiter you pop into the next gear. Done that dragracing my xv1100 tons of times.
Big rigs float gears, clutch only for starting and stopping. Use rpms to shift/float gears... very nice...😊
Exactly. I used my clutch to stop and start only.
I call it the Start Pedal, the Stop Pedal, and the Passing Pedal, because I did everything else with cruise control and Jake lol
Also a very slow way to shift if not automated.
Big rigs don’t have fragile synchronizers in their transmissions. They have dog gear engagement so they have to float gears if they ever want it to pop in.
If you float gears in a regular car, you’re just wearing out your synchronizers for no reason.
“Don’t shift like a noob”
Sounds like something a Honda civic owner would say at 3AM
Best thing about fast n' furious, is that it convinces me that my japo eco box beater is a race car.
Probably shouldn't take people seriously who use the word "noob"

In low power cars where there is no risk of loosing traction, power shifting is valid way to get you out of trouble. For example if you miscalculate overtaking distance.
How would they know? Shifting from Park to Drive isn’t shifting.
If you told me 15 years ago that one of the last manual transmission cars you could buy was a Cadillac I'd call you insane.
It will probably be a Suzuki built in India in 2065.
BMW still makes Manuals, Kia does too. Koenigsegg recently made a Manual+Automatic car. And there's still plenty of other cars out there that are manual
Nissan z hyundai elantra N come in manuals too
@@semi.gKoenigsegg light speed transmission is an automatic that also has a pretty good manual emulator. It is not a manual.
@@johnhunter7244 I know it's not a true manual, but as you said, it emulates a manual pretty well and it's fcking cool !
You should keep the foot on your gas, during shifting, but you must regulate it to keep the RPM same. Then you dont even notice that transition shock 😊its easy and comfortable
Yeah idk why he didn't mention that? Like ofc keeping the foot completely on the gas and running the rpm into the 7000+ will destroy the flywheel
This is how I run my dumptruck, if I can't keep my foot in the same position I shifted too early
That looks like a stooker. That is an excellent shifter. I never power shift on my manual. But dual-clutch is the way to go. I do miss double clutching with the introduction of synchros, although I still do it.
My old diesel needs to be power shifted or else you'll lose all momentum up a hill. Fortunately it doesn't rev much between gears lol.
Probably because of the huge flywheel haha
Power shifting you let off the gas a little and drop your revs to do it right
Just lug it
@dj jay sky yeah I drop the revs by about 700rpm and it usually snaps into gear near instantly. I can shift it without the clutch too I but the clutch is a job I can and have done at home but a gearbox rebuild is expensive. It's a heavy duty off road clutch with a heavy flywheel and the stock one lasted almost 300 000Ks (about 180 000ish miles).
@snjert I replaced the flywheel with a 20ish KG single mass flywheel and heavy duty off road clutch lol. The clutch is the cheapest and easiest thing to replace if broken by hard driving I find not power shifting causes way more clutch shudder than keeping my foot on the go pedal.
Granny shifting, not double-clutching like you should
Double clutching is only needed in gearboxes with bad or no snychros
Every car I've ever driven had synchronizers. I just waited for the rpm to drop enough that the gear would fall in with little effort. Is that not enough, even with hard driving? Or are you talking about cars without synchronizers?
Double clutching? U wot m8?
Now you and the mad scientist are gonna have to rip the block apart to replace the piston rings you fried.
Family!
Key hack for new drivers: When you start your car and you wanna take over someone start on 6th gear immediately for extra power on launch
Drop the clutch when you hear it roar and listen for the crunch, then you know you did it right
I drive all sorts of cars for nearly 2 decades and what I do is rev match with the gas pedal. After few minutes of driving I know what the ideal range is and whenever I up or downshift I keep my foot for the gas pedal down just a bit. It costs a bit more gas but the car is happy, no engine or transmission issues.
You only need to tap the clutch, not fully disengage it.
It really helps if it's not your car as well.
My boss had a diesel Renault that loved flat shifting, it also needed new engine mounts every year.
Every work van I've ever been given to drive was like that.....!
"Not my clutch?
NOT MY PROBLEM !!!! "
You legend 🤣😂
Evil af XD
Work van crunches in 4th gear, not my problem im not double clutching to stop it🤣
Suddenly I understand those "How is my driving?" stickers a LOT better...
Real men don’t need clutches to shift, just exceptional timing

Wars are best left to the pros, but unfortunately the world is full of rank amateurs.
Actually my dad did this with old soviet trucks back in the days. He was a truck driver in his early 20s in the Eastern Block
Floating gears isn't hard
It shortens the life of synchronizers by not using the clutch. BTW it's not that difficult to shift without the clutch.
Porsche 991.2 GT3 manual allows power shifting. It’s very odd to get used to. Porsche has it worked out. Between shifts the revs stay flat. I rarely use it unless I think about it.

Great video but please make more of ones to enlighten people. I stumbled upon someone complaining in your comment section about loosing job and seeking for help. Having multiple income sources is very crucial to financial growth.
Ideal words. Investments have always been the best alternative; having multiple investments increases your benefits and provides you with other revenue streams.
I realized the benefits of investing. My source of income had previously been my job. But I lost my job when the pandemic started and I had to live with the little I had in my savings which really affected my plans.
This is exactly what I'm talking about. For the past four years, my income has never been dependent on any firm or work place, because I chose to invest and the more money I get the more I seek for new investment opportunities.
Unfortunately having a job doesn't mean security. So I really appreciate John Joseph's transparency and help on my trades.
I came across this name John Joseph when I was really looking to start up some investments. But I wasn't given much information about him.

Turbo lag reduction is a thing
@@JohnWiku true. I never heard someone put it that way is all. He's right. I'd say most of the energy going out the exhaust is heat, but I get what he was saying.
I used to power shift a lot with my beater micra when I tried to kill it. Other times I just didn't use the clutch at all, just rev matched and let the engine stall when coming to a red light, then used the starter to get going again..
It eventually went to the scrapyard after the inspector pushed the floormat to the ground through the floor. May she rust in peace.
Shifting with no clutch is no big deal. I can shift with no clutch all day. Just need to find the correct rpm for your car. Usually around 2k rpm

The voice of Optimus Prime once said, "be strong enough to be gentle." When working with any machine, I keep that in mind. It can rip itself apart, so learn what it needs, use the lightest touch possible for it, and it'll do whatever you want. The bigger the machine, the more true this becomes.
Yep, you're the softest thing in the room.
Yes power shifting is hard on the clutch and shocks the driveline, but it keeps the engine and turbo spooled up and some of that screaming engine energy also gets dumped into the driveline, further accelerating you when you dump the clutch.
If you want the fastest 1/4 mile times, want the quickest acceleration or want to beat your buddy driving an identical car, then power shifting will get you there.
The downside is you'll be replacing clutches and rebuilding the gearbox and driveline components far more often (but many will argue that's the price you pay for racing).
Best practices regarding racing and parts longevity being totally at odds of course.
I personally think that this short is ment to teach about street/lighter track driving and taking care about your car. A drag project is just something you know will explode eventually, so there's almost no point in being gentle with it, just replace parts as needed to keep it running.

my neighbors son always shift like that , redline just in gear one , i love my life
With the sticks I've had, I'd take my foot off the gas when pressing the clutch, but I wouldn't completely release the gas. I'd ease up just enough where the engine RPMs were close to matching up with the next gear. Or, giving it enough gas to rev slightly on a down shift. The general rule I followed was to try to match engine RPM to the needed RPM for the gear I was shifting to. That produced the smoothest shifts, which seemed to be the best way to extend engine and transmission life.
I’ve experienced this, and gotta say that’s the best way to drive, ‘Cause now the vehicle would drive like an automatic transmission 😊
If you do that properly, you don’t even need to use the clutch. Thats how you shift in most tractor trailers. You only use the clutch when you stop and take off. Beside that, rev match to the next gear and send it. You can do it with smaller vehicles too but just a little harder to do and get used to.
I've never owned a car with a light enough flywheel to drop enough RPMs to match when shifting. They drop enough to keep it smooth but not enough to truly match.
My 2005 stick shift Kia Rio had no tachometer had to do it all by sound. That being said I feel like this guy in the video was shifting extremely slow. Also I could get my FWD Rio to drift and burn out from 1st gear through second gear and chirp going into 3rd. Good times 👍
Except it's faster. Or maybe my automatic is just slow. It Akes like 0.5 seconds of no power per shift.
Once your clutch is a bit shaven Powershifting is super smooth, trust me bro

Right. Just gotta break it in and it’s fine

I knew of cars that ignore throttle input when you pushed the pedal lightly and shift gears. Pretty convinient
I might be crazy but I love those Caddy V cars.
The abusive stuff I see people do with their cars! I have a rare Mercedes Cosworth that I use for the track, I’m not saying I don’t run it hard, but I’m respectful to the machine. No dumping the clutch for burnouts, no doing donuts, and certainly no power shifts. If you want your stuff to last, treat it with respect. Treat it like it’s a sentient being, and it will love you back.

Your transmission hates you hahahaha
@@snjert8406 transmission, tyres, hubs, driveshafts/halfshafts, ect.
I had a mustang svt cobra that would do that simply by properly downshifting from third or fourth to second gear and then stomping the gas once the clutch was safely and properly re-engaged, unless you were going over forty, in which case it would just throw the whole back end out and go squirrelly until you let up on the gas or until you spun out.
... I got extremely good at keeping the frontend pointing forward and righting spin outs while driving that car. I have an almost supernatural muscle memory reflex now for turning out of spins on ice and snow now. I don't even know I'm doing it half the time, if the car loses traction it just happens. If I fishtail most of the time it only takes a short quick counter steer and lifting my foot off the gas, and I just don't even realize it when it happens unless a passenger freaks out or something, anymore.
My work dumptruck can start rolling in 3rd... "I think she's cold... Oh that wasn't 1st"

English driving instructors will scream at you if you even attempt that. Getting out of gear just gives a nasty reving noise if you leave power on.

Rev matching on the up shift is just as important as rev matching on the downshift. You see too many people banging the clutch up and wonder why it needs a flywheel and clutch every 10k miles
Exactly this.
If I go from 4th gear to 3rd... The RPM will naturally go up...
But.....if.... When the clutch is pressed...I Rev it up a little bit so that it matches the RPM of that gear...is that okay?
That's Rev matching right?
@@pathania3377 that’s what you are meant to do. Not only does it take the stress and shock out the clutch from engaging the flywheel at different speeds it also helps wait transfer as well.
@@pathania3377 but downshifting without “blipping the throttle” to match the rev a you can still downshift with just brining the clutch up slowly to match revvs. The issue lies when you get clowns that bang the clutch up when changing gears. All this will do is transfer massive amounts of shock through the clutch and flywheel and cause serious damage. Especially with cars having dual mass flywheels they are a weak point even when driving round town
@@RosskoPeeko rev matching is ment to make your clutch last longer, it's not necesary and mostly car people do it because we care about our cars and want that budget for our projects rather than maintenance. It's a small detail but if mastered you can make a clutch last twice as long

"Breath" the throttle for a moment on shifts...your clutch, transmission, and wallet will thank you...
For all the manual cars I’ve had, I wished the engine RPM would drop faster so I could smoothly shift faster. I suppose that’s partly what a lighter flywheel is for.
I love my Blackwing! Too scared to try no-lift shift on any public road 😅
Glad i got no lift Shift in the ZL1 so were good there
I always thought power shifting was shifting without the clutch but still modulating the throttle. Never lifting your foot off the throttle but using the clutch I thought was flat foot shifting.
There is a few names for it. WOT shifting is another. I call it flat foot shifting myself. But, flat foot shifting, WOT shifting, power shifting all mean the same thing.

The only time I’ve seen someone properly power shift was when F1 cars still hand manual transmissions, however those guys were slamming the shifter into each gear incredibly fast ( less than half a second ) but they’d only do it in qualifying because it destroyed their gearboxes, it’s almost always more efficient just to quickly upshift normally, easier on the gearbox and would usually take the same amount of time anyways. It’s not worth it unless you’re chasing a tenth on the track
yeah i shift so fast it is almost like i never actually shifted in the first place gear box is "lose" enough to not know the difference and the engine trans doesn't react fast enough for it to matter lol. no speed lost it really weird everyone that rides with me ask if i even press the clutch it so smooth half the time they don't even know its a manual lol.
@@userunknown1030 lol, you probably only have 3 gears out of your 6 left.
@@tarkitarker0815 yeah probably still gets the job done though lol.
There are aftermarket ecu's that allow flat shifting. You keep it pinned, when the clutch switch engages the computer lowers the rev limiter to whatever rpm you set and then goes away once the clutch is released.
@DriftNick for a sequential shifter yes. A lot of high performance bikes have them from the factory too. That cuts ignition for a few milliseconds to unload the transmission and allow the shifter to change gears. That works off a pressure switch on the shifter. The system I'm talking about, you actually set a target rpm for when the clutch is disengaged. It can cut fuel, ignition or both. Fuel cut cost me a motor one time though when it went lean under boost so I only use ignition cut now.
Oh, that clutch! 😬
I remember trying it once, and when the spike occured, my guts outright screamed at me that it wasn't a good thing to do. It's like that hunch you get where you get a sense that something wasn't supposed to be used that way.
I used to power shift 3-4 in my s2000 and it definitely loved it lol
Now it's interesting because I had to learn how to power shift, to keep one of my work's trucks from stalling on a hill. Granted you are still lower the rpm from 2100 to about 1500; but it's difficult to find the gear again, when you miss the mark.
Also you save lots of wear-and-tear on the clutch by float shifting instead of clutch shifting. There are a few automatic transmissions that are based entirely on float shifting.
Isn’t it better to stay in the lower gear until you are up the hill?
@@batman3698 it's better to not shift in general, when you are on a hill. If you can shift into a lower gear, do it at the base of a hill. But If you take the hill at speed, then there is no getting around having to shift, when you halfway up it. Now this one hill, coming out of a pit, is steep enough that if you stop on the hill, you'll never get going again; even trying to take off from low 1, which is a granny gear.
In a drag or a close pursuit, quick power shifting provides an extra forward thrust with each gear change, which loads and damages the clutch less than downshifting without hitting the gaz (without synchronizing the engine and the gearbox): in the first case, the clutch friction is reducing the engine rotation, in the second case it’s increasing it.

One weapon with a upgrade like the Lead Storms final one. 3 Sidearms.
The real G's know how to keep the revs just right through a shift. Powershifts are for idiots
It kinda makes sense to counter turbo lag.
If you keep a steady rpm, you can do it fine. On big trucks, I've seen people who were so used to diving them, they could shift without even using the clutch. Apparently, there's a sweet spot in the rpm where it'll just slide in and out.
Clutchless shifting. Usually easier to do on bikes. But sometimes I accidentally shift up without engaging the clutch.
My gf flipped when I did this in her car, thought the clutch was gone
The sprockets to shaft couplings in trucks gearboxes have a different construction than the ones in the cars manual gearboxes. Powershifting on regular manual gearbox cars is the best way to prematurely wear out or destroy the clutch and even the gears.
always thought that the shifting in fast and furious was goofy but now i understand why they always do it when they shift.
Downshifting with rpm matching is fun though
If you know your car perfectly, it feels smoother to match the rpm yourself, especially if you drive a shitterbox with dying synchronisators
Remember kids, only power shift if your car had sequential gearbox
Or it's a hire car 😂
no, most tuning software has an option cut ignition when clutch is pushed in for you to NLTS or “power shift”
New here, I looooove manual transmissions and I hate that they are going away in the states 😢
“Power shift” 2012 Ford Focus transmission PTSD intensifies
Had a friend back in the 70s power shift to win races, and he'd replace clutches like candy.
I’ve got flat foot shifting in my ST. It really does make a difference
Wait so with Cadillac, if sparks are delayed when clutch is depressed, is it still feasible to rev match?
Yes, this is referring to upshifts, not downshifts. For sure can still rev-match downshifts, and have the option to have the car rev-match for you.
@@EngineeringExplained ah okay thanks!
If you have a synchronized gearbox there's no need the RevMatch
@@djjaysky9071 not true; synchros do help a lot, but they're going to wear out and get torn off too. They leave a lot of extra room for mistakes and can help significantly, but if you're 3k off your gearbox will still be mad at you.
@@EngineeringExplained How does the car even know if you are going to upshift or unshift, or even do nothing?
I've never seen anyone do this.
The fastest manual upshift I've ever seen was from an ex shifter kart driver who started doing rallycross. He upshifted the dogbox transmission without clutching. Just, lifted, put the shift lever in neutral for a split second and slammed it into the next gear
That is how dogboxes are designed to be shifted so if you have never seen anyone do it you haven't looked very hard lol
Interesting, thanks . I didn't even know this was a thing. My old teacher always said to imagine what the metal is doing. Interesting power shifting can be tuned for 👍learn something everyday
Concise and straight to the point, love this
You have to feel the engine and clutch to have a maximum torque. You will tear your clutch smelling burns if you this power shift. Rev matching is very important!
Me using a sort of power shifting with my old car from 2003
not really related but this made me think of it. i was at a light and i had to turn left to go up a hill. i gunned it and accidentally spun tires in my wrx. i told my friend that also has a wrx. he said, oh you shouldn’t do that you’ll blow the trans. he clutch kicks on pavement all the time. and his clutch and trans are in way worse shape than mine. because tires breaking traction is worse than slamming the clutch in while holding the gas down and letting out, you know because transmissions really want to be at the wrong rpm
