sorry, I read that to mean there was no clutch on a bike too... :p

Powershifting has no bearing whatsoever on GT3, since the manual transmission is sequential like a motorcyle transmission, and there's no clutch.

that concave cylindrical gear system certainly sounds like the future. isn't it already employed on things like electric trains or something? there was a time when auto gearboxes couldn't handle large torque, now look at the SL55...

anyway i've powershifted my car before, but not ever tried shifting without the clutch. though if i understand correctly, if u have to wait for the revs to fall, surely you can't powershift without using a clutch right?

and if u need to wait for the revs to fall, isn't it quicker to use the clutch and just shift without waiting for anything?

i saw this thing at a motorshow where the gearbox automatically engaged the clutch when u had the leaver in neutral and were about to move it to the next gear...

Yes, that is the way a clutchless manual system works, it is also the way sequential transmissions work(though they clutch when you press the paddle).

The CVT is the way of the future, unfortounatly, as of yet they cannot handle large amounts of power, no torque would be transfered once you gassed the engine to much, so sequential transmissions are the way to go right now. The most advanced of which is the new audi sequential, however it also suffers from high torque problems, but that can be fixed more easily than a CVT can i think.
















There are clutches in gt3, that is why one of the upgrades is a clutch upgrade.
 
You can clutchless shift fine in manual road cars, by matching revs between gears. Funnily enough, its just like driving a crash-box (no synchromesh) which are still used in modern trucks. Match revs, lift, shift.

Racing drivers use it when they are left foot braking. Having both feet busy coming into a corner requires you to shift without a clutch. It happens in V8 supercars (australian thing.. the GT3 tickford falcon is one). Some drivers use left foot braking to give them more control into a corner, whilst others still clutch, and brake with their right foot.

I've driven my own car for thousands of km without using the clutch to change between gears and its still fine. All the synchro's are present and there's no pulsing, which means i haven't spat teeth around the gearbox.

Shifting down requires a blip to push the revs up to the right range (Shifting down causes the engine to speed up, which is why people do heel-toe). The downshift is much faster this way than a standard shift, unless you jump off the clutch fast and jolt the hell out of the car. This would cause the brakes on the driving wheels to lock under hard decceleration.
 
Well the best example I can give right now to a clutchless car with a clutch..IE..electronicly activated...
is the new MR-S..it has a sequential gearbox with an electronicly controlled clutch..So just like the automatics with "tiptronic" shifting..you can go through all of your gears with more control than a tiptronic, but without having to depress the clutch pedle...Although it DOES have a clutch pedle you can use

Huh?

You blew the clutch, and you didn't fix it, but the transmission "ran just fine" without the clutch? Did you have someone push it for you until you got up to 15-20 MPH and could put it into first gear? And what does any of that have to do with power shifting? It doesn't sound like you even know what power shifting is. Go read the explanation that's already been given in this thread.

BBM, just because I used the term "blow" dosen't mean the cluth totally disintergrated, just that it had weakened to a point where it was not very effective. The more intelligent thread readers picked up on this. Pressing in the clutch still allowed the flywheel to be released and separated from the transmission, but it wasn't functioning properly. Through time I got used to the fact the clutch was failing and just got along without it and yes, there were many times when I needed a jump start, and the clutch would slip occasionally going upgrade or with items in the back. The fact that the transmission still functioned I used the term "fine" to describe it.

Changing gears without using the clutch is speed shifting, along with other factors, and explaning this wasn't necessary since neon already did with enough explanation for anyone to get the gist of it, so why should I bother?

Threads often start conversations with stories or information that is either related or not directly related to the thread topic so get use to it.

Next time show a little more restraint before mouthing off, maybe you will make more friends here.

Shinez, you might be playing nice at the moment, but nobody's forgotten your little tantrum last time. It took vat_man a lot of time to clean that up.

You are not welcome here any longer.

Because in his first account, he was very argumentative and showed zero respect for other members. After repeated warnings and requests to behave, he was banned. He then chose to come back with a series of new accounts and pitch a little temper tantrum all over the boards, posting polls asking if the mods were gay, etc. etc. and generally acting like a four-year-old. So he's no longer welcome here no matter how nice he pretends to be at the beginning. We've been down that road with at least 3 accounts for him, and it's not going to happen again.

there an even stronger power shift........oh well if u guys dont know forget its.

What is it that you do? That's the whole question. How do you powershift when there is already no need to lift throttle even for a millisecond when you upshift?

And when I say there is no clutch in GT3, I mean there is no clutch you can control. No way to slip it, no way to do anything with it, no way to modify your launch except with the throttle.
 
power shifting is more commonly referred to as "flat-shifting".

This pearl of wisdom is brought to you by: Omo Brand washing powder - "whiter, brighter."
 
I think the term 'power shifting' is a bit mis-leading. Shifting under power with a standard manual transmission makes really nasty noises - trust me. ;)

I taught myself to shift my WRX clutch-less, but I'm pretty quick with a pedal so I don't do it very often.
