Hello,

I am practicing rev matching when downshifting and was wondering if anyone has a table with the different rev and speed for each gear. I am trying to figure this out but not not getting it right. I would like to know some common revs you guys use when downshifting into different gears. Thanks.

 

What are you having problem with? Either give it more gas or less gas.

 

He is having an issue with Rev matching and wants a chart for what revs he should be at when he shifts from gear to gear. I dont know if this is possible but I guess he needs help with rev matching

I would totally answer this question for you, but I have an AT, I still wish there were used MT's in my area at the time :O

 

You don't need a chart, just listen to your car...

 

haha ya, more or less gas settles it. practice and with time youll have smooth downshifts . or save up for a 370z...problem solved

 

yea...the chart wont really do anything for u. ur making downshifting more complicated then it needs to be. all u gotta do is practice and have a good memory. If ur car lurches then u rev'd too high, if ur car lugs then u didnt rev high enough. then next time do it right. simple as that.

 

You shouldn't look at the tach at all, once you get the hang of it, it's easy to do it by feel. Basically, it's far harder for the transmission to rev up the engine if you under-rev than it is for the transmission to slow down the engine when you over-rev. So, err on the side of too many revs. Eventually, you'll over-rev less and less until you get it perfect. I'm pretty good at rev matching, and I still occasionally miss one. Good luck.

 

Whats up with the Z? Slipper clutch or something

 

It automatically blips the throttle for you when downshifting.

 

u will never learn to rev-match by actually looking at the tach. Practice will make u actually "feel" the car and you will perfect it with any gear.

After having my car for 4 years, i recently drove the 370z 6MT and i the my revmatching was as good as the "synchrorev" feature on. The gear ratios and everything is different on the Z compared to my 2004 6MT but i was still able to revmatch like my own car. I know this sounds weird but u actually have to get a feel for the car and how the tranny/clutch works.

 

Uh yea...I read his first post, so I know what he wants. He should want to give it more gas or less gas when shifting into a lower gear.

Everyone else summed it up. Seems like he needs to work on his coordination.

true true... I looked at the tach at first just to know where my rpms are with thee sound of my car. Now I dont have to look. I have also found timing works, if I'm blasting my music and cant hear the car perfectly then I know about where and when to shift.

So basically what I do is
1. hear and feel the car
2. approximate time
3. if for some reason I cant do the two above I then look at the tach


hope this helped.

 

Try to learn the distance between the gears, its about 2500-3000 rpms when you up shift start to get a feel where the rpm drops to and when you down shift get a feel for how much it raises the rpm, after you are comfortable and get a feel for the rpm changes get on a highway and maintain a constant speed, then practice downshifting and keep blipping the throttle until you get a feel for how much throttle it takes to raise the rpm to match the distance between gears. Make sense? if the car lurches forward you gave it to much, dives. to little. and take your time initially. Its one of the joys of owning a close ratio gear box, learning how to keep you car in the sweetspot. one more tip and I will stop this ultra long post..run through the gears on a 0-60 run and get a feel for when you hit the sweet spot in each gear aroun 4000, thats where you will want to down shift to when you get on it.

 

The only true way to do this is just practice and a feel for the car... a chart, if one existed, would essentially be useless.

 

i wont really read other's post but..... just a rule of thumb...

everytime you downshift one gear (at the constant speed), it goes up roughly 1k rpms. so lets say your going 60mph at 5th gear@3000 rpm. soon as you downshift into 4th, you'll hit about 4k. it doesnt work out to 1k as each gear ratio is different, this is where you have to practice and learn your car. but this is a good rule of thumb to help you learn.
