shifting at redline

when upshifting at the redline say from 1st to 2nd gear, what is the exact technique that should be used? are you supposed to start giving some gas as u release the clutch (with gear shifted into 2nd gear already) or are you supposed to just shift into 2nd gear and release the clutch, THEN gas?

rev matching will give you the smo0thest shifts. It should all be a fluid motion though ... gas pedal going down as clutch pedal is coming up.

I'm definitely a newb myself, but I think I can answer this one. The 'chirp' is when shifting from 1st to 2nd, the rear wheels peeling out such as in 1st gear, but only for a very short duration; making the sound of a slight 'chirp' instead of a long 'screeeeeech' in 1st. My first post btw

Getting G in March[fingers crossed]

^^ yup your right. A chirp is when your tires break traction for barely a second and makes a chirping noise.

You're not really needing to "rev match" when you're upshifting, persay.


Say we're going from first gear to second gear. For our scenario, your redline is 6k rpms, and at 30 mph, which is the fastest you can go in first gear, you shift to second, which driving at 30 mph in second is 4k rpms.

So if you were redlining first gear, as you clutch in to shift to 2nd, the rpms are dropping as you have stopped pressing the gas pedal, and ideally you should be clutching out so that the rpms don't fall below 4k rpms as that would be the rpm you will match as you're going at 30 mph.

i see, i usually chirp when i go from 1st to 2nd, but i wasn't sure if this is the quickest way to accelerate because you lose some traction when u chirp, which is why i asked my original question. so it seems like pressing down on gas as you're releasing the clutch is the correct way (what i've been doing).

Chirping isn't a good thing as you are essentially spinning the wheels, therefore temporarily stopping power from being transmitted from the engine to the ground.
