Power Shifting and launching the z
 

i wanna learn how to launch the car properly and how to power shift so does any one have any tips for me?

i have launched the car a few times but i want to know whats the best way to do it. what i usually do is rev the car to 4.5k -5k and then dump the clutch and press the gas pedal all the way. what i want to know is am i supposed to take it easy on the gas at first and after the car starts rolling then press it all the way or press it all the way from the beginning while releasing the clutch? by the way when i do this i get a lot of wheel spin and i want to know how to stop that from happening. another thing that happens sometimes is the car starts jerking for 2 seconds then the car starts moving forward. i think that happens because i let out the clutch to early and i hit the gas to fast.



power shifting

well when i want to drive the car fast what i do is. take off the car slowly in first then press the gas all the way and once i hit 7.5k rpm i press the clutch let go of the gas shift then let go of the clutch and hit the gas. what i do is just dump the clutch like that on every gear. i use to think that thats power shifting but then i read another post and i got confused.

so is power shifting holding the gas the whole time while shifting from 1st gear to 6th? hold the gas then hit the clutch while holding the gas and shift then let go of the clutch while still holding the gas? am i understanding this right?

and which method is better the way i do it? as in let go of the gas or shift while holding the gas? can someone plz explain this to me so i can get this once and for all.

its so funny i can rev match and i can heal and toe and i do it really fast too but i have no idea on how to launch the car or power shift. :(

I'd be interested too.

I just did a 1/4 mile run this Tuesday - 14.022s @ 99.22mph. I let the clutch out at ~3500rpm and still spun for a good half second before gaining traction otherwise I could have hit mid 13's. 4.5k - 5k sounds way too high to me. You want the tire chirp. I have to experiment with it more.

Power shifting to me I thought was shifting at the proper time each gear to keep the RPM needle in the peak power band for maximum torque (not HP).

And dumping the clutch is bad unless you're planning on replacing it a lot sooner than you would normally. You can ease relatively slowly into 1st and still pull down a decent time. Dumping through 2,3,4 isn't as bad since the change in revs isn't as great as dumping from 4k

yeah ur right. dumping from 2nd 3rd 4rd 5th 6th isnt as bad as 1st but i still want someone to confirm if power shifting is changing gears while the gas pedal is fully pressed from 1st to 6th. and also if we dont dump the clutch and get back on the gas very fast our 1/4 mile time would be much slower then automatic because if you dont dump it then its going to take more time to get back on the gas while in automatic the gas pedal is always pressed down

Agreed. I have no problem dumping through 2,3,4 but dumping at 1st isn't worth it unless you're ready to pay for a new clutch a lot sooner. Or - get your time as low and consistent as possible easing into 1st, then dump 1st to shave it down. That way at least you're not tearing up your clutch while still trying to get the hang of shifting properly through to 3rd or 4th to keep your power up

As you've described, power shifting is a method of quicker manual transmission shifts executed by maintaining your throttle position in the engine's peak power band while depressing the clutch, shifting and then releasing the clutch (ie as opposed to lifting off the throttle during the shifting). While this may shave a few tenths of a second off your times, it will also turn your clutch into smoke faster as well.

Is power shifting 'better' than a normal shift with throttle lift? If you're going to the grocery store, no. If you're trying to set a land speed record for the 1/4 mile, perhaps.

i guess i need to practice this a little bit more
