Default rev-matching question

hey guys, quick question. How did you guys get good at rev-matching? I've been practicing it for a week and a half and I find that I'm fairly inconsistent. Some days I'll be smooth, the other days I'm either overrevving or underrevving.

Is the best way to learn to rev-match by feel? I find myself staring at the tach everytime I rev match and thinking about what rpm I should be blipping the throttle to. I've read on standardshift.com that its better to learn to rev match by feel instead of thinking about what rpm to blip the throttle to in each gear. Is this correct? Sorry about the noob question guys, but I finally got my upshifts smooth (for the most part...1-2 still jerky when the cars cold) and I want to make sure I'm practicing how to rev match the right way. Thanks!

It depends. Sometimes if you're in a higher gear and not going as fast you don't need that big of a blip. I usually note that it's from 1000-2000 rpm blip.

for me, i go by what rpms i should be at at what speed and gear. then when i "blip", i shoot for a little above what i should be at, then by the time i shift it's at the right speed.

3rd gear is easiest, since it's pretty closely matched with MPH.

so if you are to go by my technique (and what you are currently doing), make sure you know how fast the engine should be spinning for the speed/gear you want!

First, practice by coming up to a turn at a speed that you'll not need to brake (ie slowly) before turning and downshifting. That will eliminate the braking part of the equation and allow you to get the throttle blip part down cold. Don't use the tach, use your ear. Maybe even start in a straight line at low speeds (an open parking lot?), just run up to say 2000rpm in 3rd then blip-shift (into second) and release the clutch for as smooth a transition as you can. The blip-shift-clutch release is a fast process in a car with a free revving motor like the S2000. In my 944 you have to really give the throttle a big stab to get the revs up, where the S2k is more like a motorcycle (a quick blip is all you need).
Once you can make the downshift a smooth transition, add the braking and turning part.
Learning to do this by ear will allow you to more readily transfer your newfound skills to other cars

i do it by feel. id be too affraid to sit there and stare at the tach while trying to slow down or make a turn. i am never 100% consistent either. it takes a while and a lot of practice to get perfect at it. it seems to me tho, in the s2k, that no matter what gear you are in as long as you are going from one gear down to the next lowest one (i.e. 6-5, 5-4, 4-3, etc) the F20 usuall only requires a small blip of the throttle. i wish i could use the heel-toe technique but my damn feet/legs are too big.

good luck tho.

These guys are right. Go by your hearing, never look down at the tach.

And if you're learning all this, just take the extra step and do it right, learn to double clutch in addition to the rev matching.

Practice, practice, practice. It helps to look at the tach in the beginning to see how much of a blip you need to get your revs matched properly, but don't rely on it every time. After a couple months, you should be a pro

I would recommend that before you practice a rev-match before entering a turn I would practice in a straight line.

Simply select a gear like 6th gear for starters. Cruising at 65mph at a little over 4K rpm. Practice putting the clutch in and blipping the throttle by itself. Don't shift. Every so often, clutch in and blip the throttle. Listen for the sound. Get it consistent.

Then when you are cruising in 6th gear. Blip the throttle and downshift to 5th. If you can do so without jerking the car but you are now cruising at a higher rpm...then you've done it correctly. Do it a couple more times from 6th to 5th.

Once you've got that down.... practice rev-matching from 6th to 5th....and then try it one more time from 5th to 4th and maintain the 65mph. The shift should be smooth with the only thing changing being the rpm.

Once you can do this... you will be able to rev-match at slower speeds, when engine braking and even before entering corners.
