okay. this is a long post. I will try to explain this the best I can without trying to confuse you people. sorry if i'm not clear enough. but please try to understand and help me out.

i do perfect launches. i feather my clutch about 3.5-4k and have a good launch. after my tires get grip and starts to pull, it's time to shift to 2nd. now in 1st, my gas is ALL the way down. I pull the clutch in, let off the gas, switch to 2nd, SLAM the gas, then pop the clutch and chirp in second. after i do my launch, i basically keep doing the same technique. BUT LATELY, i've been trying something else. i'm sure everybody else does it but it was my first time. after i launch, my foot is on the gas all the way, i pull in the clutch, leave my foot on the gas all the way down, shift to 2nd, then pop the clutch and i just go. i've been tryin this through all my gears. everytime i get off the freeway, i smell the burnt clutch smell. something is burning everytime i leave my foot on the gas and shift. is that normal? i never smelled this while letting off the gas. is keeping the gas pedal all the way down at ALL times much quicker? can someone please help me? i'm lost.

 

It is quicker if u do it right but its a lot of stress on the car. Dont do it whenever u feel like it. Just do it when there is special occassion like beating a car that is as fast as u or faster than urs.

 

thanks for the reply. yeah i dont do it often. just the past couple days to learn it really good. so it is quicker. interesting. you have put my mind at ease, lol. thanks.

 

The gains from powershifting are negligible in most cases. We're talking hundredths of a second here. I do it at the track, but even then, I don't do it all the time.

 

In my last MT car, powershifting was worth between 1-3 tenths in the quarter.

It isn't the kindest way to treat your clutch/syncros.

 

Sure. It's a much quicker way to send you clutch, flywheel, fork, TB, and entire tranny to the graveyard. Like Trey, said powershifting results in neglible gains unless you're a really slow shifter. Is that .03-.07 seconds in the 1/4 mile worth a $1000 clutch or $2500 tranny?

 

so thats what powershifting is? i didn't know that. i always heard of that term but never knew what it meant. also, one more question. is double clutching worth it? i've read its not worth it in the newer engines.
is what i'm thinking of called double clutching?
example: launch in 1st. clutch in, shift to nuetral, clutch out, clutch in, shift to 2nd, then pop the clutch.
is that double clutching? i really appreciate all the info given. thank you again.

Double clutching is a superflous activity in a syncro-equipped transmission.

If anyone thinks powershifting is worth less than a tenth, go talk to Alberto on My350z.com.

 

I can shift almost as fast as powershifting, I have tested it many times in our 12 sec allmotor car. all runs with and without powershifting were almost exactly the same ET, and we let other so called pro drivers give the car a go and they all ran 2-3 tenths slower then my times powershifting.

 

thanks man. that link did help me. i understand exactly what double clutching is.

 

I would not recommend you powershift unless you want to be replacing your clutch and flywheel sooner. The burn smell you speak of is the clutch disk slipping on the flywheel and not able to hold the power. I have yet to powershift in my car and don't plan to any time soon.

special occsions only....

 

Exactly. I powershifted my Maxima a handful of times and saw absolutely no change. Same goes for when I was driving my friends various 5.0s on strip. The Mustang and F-body crowd always seem to be in agreement that if you're a quick shifter, powershifting really won't net you much of anything (ie less than a .1). I don' see why an FM car would be any different especially considering the throws are far shorter than the OEM shifters found in F-Bodies and Stangs.

 

On a purely technical note, there might be some advantage in powershifting these cars, though it's only speculation. Some of the AT cars have been observed to have timing pulled by significant amounts when shifting. I would assume that the ecu would do something similar for the manual cars, but that's just a guess. So the question would be, would the ecu pull as much timing with full throttle position when the clutch is engaged, or not.

That would be an interesting experiment with something like the techtom or the cipher...
