full throttle shift = powershift?
 

wtf. well powershift whatever it is, i have come to the conclusion that it is a fullthrottle shift, is this efficient in drag racing, sorr im just a bit intoxiacated. btw fuckthe backspace key

Re:full throttle shift = powershift?
 

Damn that backspace key...

Re:full throttle shift = powershift?
 

that bastard :(

Re:full throttle shift = powershift?
 

congratuatlions on becoming a post -----, join the club buddy, you'll have a while before youre at where i am

Re:full throttle shift = powershift?
 

Ive seen crankshafts break cause of powershifting... that being said, when you do it get some video ;)

Re:full throttle shift = powershift?
 

honda's dont break cranks powershifting.. lol.. ask ANY pro import drag racer if they have broken a crank while powershifting (they all do it if they are in sup 11's~

Re:full throttle shift = powershift?
 

rotaries dont have crank shafts. lol

Re:full throttle shift = powershift?
 

If rotories dont have crankshafts what spins the rotors?

Re:full throttle shift = powershift?
 

expanding gasses spin the rotars on rotaries. the eccentric shaft keeps them following the correct path.


---- power shifting, just double clutch, check out my thread from last year on double clutching, has some good information.

Re:full throttle shift = powershift?
 

a link would be nice...ay si ...check out my write up..muy chingon...

Re:full throttle shift = powershift?
 

Double clutching is used when your downshifting. Stop watching thr fast and the furious.

Re:full throttle shift = powershift?
 

just add a 100 shot and tune the map and you'll run 9s

Re:full throttle shift = powershift?
 

you're about a year too late on flaming me for that, but thanks anyways. and rev matching is for down shifting, double clutching is for driving ---- without syncromesh.

Re:full throttle shift = powershift?
 

um.. both "powershifting" and double-clutch is gay IMO... to each their own but if you have to do that ---- to win or keep up.. learn how to drive better. i used to double-clutch till i found out that its not worth the headache in the long run. thats just my $.02 if anyone cares... peace

Re:full throttle shift = powershift?
 

rev matching/double clutching... the same thing. Go drive an old ford/chevy truck with a manual tranny. You will have to double clutch if you want to shift from 2nd to 1st gear (you will probably have to do this in your honda too).

Double clutching/rev matching... clutch in, put it in neutral, clutch out, rev the engine, clutch in, then shift down.



Oh and to stay on topic I power/speed shift all the time and your right it's just full throttle shifting. Leave the gas to the floor and shift like normal.

Re:full throttle shift = powershift?
 

I use a switch on the clutch pedal to engage a 2-step limiter, that way I can shift quick without having clutch problems (clutch goes up in smoke if the engine is at 15psi boost and 6500rpm, and the drivetrain tries to force it down to 4500rpm or so...)

Re:full throttle shift = powershift?
 

Powershifting is not gay!! For NA it can considerably lower your quarter mile times, its not hype. Ask any muscle car drag racer if he power shifts.

Re:full throttle shift = powershift?
 

Re:full throttle shift = powershift?
 

I just rev match, one clutch throw, simple, easy. in second, push clutch, rev match, put in first, let clutch out.

Re:full throttle shift = powershift?
 

Yeah dude that is double clutching... same thing...

Re:full throttle shift = powershift?
 

it's not double clutching because I only push the clutch in once. if that's double clutching then I double clutch everytime I drive anything because I always rev match even when up shifting if I shift slow.

Re:full throttle shift = powershift?
 

who said anything about rotaries?

Re:full throttle shift = powershift?
 

kain did.

Re:full throttle shift = powershift?
 

WTF? you rev match when you upshift? What the hell is that going to do? Just ------- leave it at WOT or shift like normal.

Double clutching = when your downshifting in an old truck... end of story.

I ------- hate stupid topics like these...

Re:full throttle shift = powershift?
 

I rev match when I'm upshifting and I sit there for a while trying to put the piece of ---- tranny in gear. I like it when other people get frustrated and I don't.

Re:full throttle shift = powershift?
 

I rev match when downshifting, just quickly blip the throttle open and close it again before letting the clutch out, makes much smoother downshifts and less clutch wear.
There is a benefit to revmatching on every shift, that benefit is that the clutch has a slightly bigger chance of surviving. I really hate the feeling of doing a hard launch, then shift into second and the engine stays at 6000rpm but the wheels are sticking.

Re:full throttle shift = powershift?
 

wow, rev match upshifting, thats about as stupid as pissing into the wind.

I've full throttle shifted a few times, 1st to 2nd it lights my freakin tires up tho.

Re:full throttle shift = powershift?
 

i am gonna agree with kyle.
rev matching is pretty much used for down shifting
double clutching is pretty much for up shifting (you let the clutch out and in twice ((double clutching)) unlike rev matching where is only once)

there really isn't a point for double clutching, it was only really used when trannys didn't have syncros.

Re:full throttle shift = powershift?
 

the funny part about that guy agreeing with me is that that's not what I said.

when your revs drop down to idle because you take your sweet ass time up shifting you too can benfit from rev matching that bitch.

Re:full throttle shift = powershift?
 

ok.

double clutching is something that is almost always done only when downshifting. it's a method of spinning up the intermediate shaft to match the gear to save wear on the synchros. This doesn't make sense upshifting because the intermediate shaft slows down on it's own when you shift from 2-N-3.

Most people don't dbl clutch any more and just let the synchros spin up the intermediate shaft. Rather they just clutch once and match the speed of the engine (as opposed to matching the engine+intermediate shaft when dbl clutching).

However, usu. the synchros are not good enough to spin up a dead intermediate shaft to match first gear going 30mph. The shifter usu. only slips into first nicely once the car has slowed to about 5mph (slow enough for the synchros to work). If you really want to downshift to first going 30mph, AND the car has been in neutral a while (dead intermediate shaft), you have to double clutch to spin the shaft up. Well, actually you'd only be doing the last "clutch" of the dbl clutch since it's in neutral already. That's probably the only time you'd use it in real life. Other than that, heel-toe downshifting is adequate for modern synchros.

Re:full throttle shift = powershift?
 

double clutching is for tractor trailers. Our Hondas have Syncros, therefore there is no need to double clutch. ::)


End of story.

Re:full throttle shift = powershift?
 

Exactly.

We already have had a few threads about this. It's for dump trucks and ---- like that. Seriously stop watching the fast and the furious.

Re:full throttle shift = powershift?
 

the only dump truck I've driven didn't require double clutching, it must have been some hot ---- racer dump truck. yes, I really have driven a dump truck so I really can say that.

Re:full throttle shift = powershift?
 

so this thread went from full throttle powershift to double clutching? wtf

Re:full throttle shift = powershift?
 

so anyways, back when my b16a actually hauled some balls before I blew it up I did a little bit of power shifting, it was pretty fun spinning those bitches on a first-second shift. now the engine can't spin ---- and my transmission doesn't like to let me into second once I redline first.

Re:full throttle shift = powershift?
 

---- double clutching. Everybody knows its not how you shift your car, its how you stand by your car. You better learn that.

Re:full throttle shift = powershift?
 

I know right? but whitey is right though :-\

Re:full throttle shift = powershift?
 

this must be that granny shifter from that night when we talked some ---- to that pizza boy, good one new guy.

Re:full throttle shift = powershift?
 

Alright forget all the ricer terminology, listen up and let whitey tech you how to shift.


1. apply gas
2. keep petal to the floor
3. push in clutch while pulling back (or pushing foreward) on the shifter
4. let out clutch
5. repeat this process and practice until desired effect is reached.
6. if you can't get it right, put some balls into your shifting you -----.



There, nice and simple and no JDM/fast and furious buzz words. There's no magic thing to do but shift like your beating a stripper and the way I ----, fast and hard.




lol

Re:full throttle shift = powershift?
 

Not really a "new guy." If regestering 26 days after you makes me a new guy then yea, I'm a noob ::)
