Rallycross Downshifting

[Wh33lhop]

are you revmatching? just forcing it into gear isn't going to work because the synchros and input shaft will have a big difference in speed.

rev matching alone won't help too much since you're clutched in as you're entering the next gear. there is still a tiny bit of friction there but it won't make that much of a difference in input shaft speed. double clutching will but that's a bit harder to learn.

you should be rev matching anyway, but in theory it won't make much of a difference. if he can't find a gear in rallycross my guess is he isn't clutching in all the way due to lack of muscle memory from performance oriented driving (or it could be his synchros just suck). if you can learn to double clutch that will definitely help, but that takes time.

Clutchless shifting on a transmission with syncros is bad juju. I do it sometimes just to show off, but I know how to unload the drivetrain properly so it's not too rough. You need a trans with dogleg engagement to do that all the time(NOT dogleg shift pattern).

Revmatching is second nature to me as well. I always get dirty looks from bystanders thinking that I'm revving it up to show off. Sheeple.

heel toe isn't that tough, it just takes practice. I can't dance for shit either, but I heel toe on every downshift. after a while you don't even think about it.

with the way the pedal is anchored in the e30 though, its more of a toe/side of foot thing lol

Elva yes rev shifting is clutchless shifting. Used most commonly in nascar for faster shifting. I'm a nascar nerd cause I've grown up around it.

Got it!
I'll give this tecnique a try,

1. Clutch in
2. Lever to neutral
3. Blip throttle
4. Engage lower gear
5. Release clutch

Thanks everyone,
Ian

don't need to move the lever to neutral. clutch in/blip throttle happens at basically the same time, and you also have your right foot on the brake with the toes on the gas (you can do it without braking too, but typically you do this while entering a corner and scrubbing speed). at this moment you move the lever to the gear you want and release the clutch.

if you time it right it'll slip right into gear at the exact RPM to match the transmission, clutch, and road speed together, and it reduces shock on the clutch/trans/drivetrain.

Okay yea that's what I visualizing. And yea rev shifting is what I gave up on. I'll pick it up when I start racing forsure.

As another tip, don't blip the throttle until AFTER you've disengaged the first gear or shifted into neutral in other words. If you blip as soon as you disengage the first gear, chances are the RPM will drop too far by the time you engage the lower gear. So:

1. Clutch in
2. Lever to neutral
3. Blip throttle
4. Engage lower gear
5. Release clutch

If this doesn't work after you've ensured your technique is correct, there's always double-declutching....


What's rev shifting? Clutchless rev-matched shifts?

[ForcedFirebird]

There's a few other techniques, but the video should give you an idea. I use the ball of my foot to brake, then roll my foot over and tap the gas with the other side of my foot.

Rev shifting. What's heel toe I got an idea of what it is but probably just need explained

^+1 to that, seems natural now, even though i have huge feet it's easy for me

However, if you're heel-toeing and still having trouble getting into 2nd it could be a different problem

[jalopi]

rev shift or heel toe? i gave up on heel toeing years ago, that shit is way too complicated for a guy who can't dance worth two fucks.

rev shifting really just takes practice with the car you're doing it with, everything's got different gear ratios & throttle responses.

but yeah, OP, clutch in -> blip throttle (maybe for a 1/2 second or so) -> move down a gear. you will notice an immediate difference, guaranteed. try practicing by getting off the highway onto slow offramps, you'll get the hang of if pretty quick that way

[ThatOneEuroE30]

I remember the first time I drove a standard.... lol.

The worst part is that kids these days won't even know about rev shifting; I figure it won't take too many more years for every stick sporty car to have that automatic rev shifter.

I've been trying to teach my self to rev shift. It's not that easy.
