This doesn't belong in under the hood. Moving to S2000 Talk.

 

I'm curious about rev-matching a downshift via double clutching versus using the throttle and clutch simultaneously. At the moment I do the latter. I know that you can burn the clutch if you rev with the clutch pedal to the floor. Let's say you continuously rev in neutral with the clutch not depressed, then you immediately let off the gas and push the clutch in. Does that do the same kind of wear as opposed to revving while you're holding down the clutch?

 

I never double clutch upon downshifting, the S2000 isn't a big rig for pete sake, I just rev-match. Almost every slowdown I downshift as if it were my primary means of slowing down. 65,000 miles later (many supercharged) and I'm still on my OEM clutch (which has som mileage still left in it)...

With a tight throttle cable (which makes blipping the throttle much easier and accurate) and some practice, anyone can perform very smooth downshifts with minimal wear on the clutch.

I have tried double clutching, it just isn't for me and I dont find it neccesary for my conditions.

That's just me...

 

Not to be the jerk here, but I do not rev match ever. I've been driving stick since I was 15 and have never had any problems with just pushing in the clutch and going in to gear...at any speeds. Maybe one day I will, but I've seen too many amature drivers screw their cars up cause they thought they were rev-matching.

Nice write-up though

 

nice write up although i already know most of the information posted. good for the noobies that don't drive stick well =]

 

i think in some states you have to downshift and you can not be in neutral at a stop light.

 

The only thing it saves is your synchronizers and in the 5 years i've been on this board I can't seem to recall one thread where just the synchros need to be replaced from wear.

Also, 99.99% of these folks will never drive a gear box with straight cut gears so let's not make it seem like it's a required skill.

IMHO, no need to double clutch.

 

i revmatch on downshift all the time. but i had no idea you're not supposed to rev your engine while the clutch is depressed. =(


what if im downshifting? im supposed to go to neutral, let the clutch out then revmatch then clutch in and downshift?

 

All this talk on rev-matching and double clutching I have to ask a couple questions.
1) Do you rev match if you are slowing to a stop or only when coming to a corner and want to enjoying the cars benefits.
2) I typically rev match to downshift at a corner but will brake and downshift when coming to a stop ( taking my foot off the clutch to allow engine to assist) any probs with that?

Thanks,

Greg

 

pretty much all trannies now are constant synchromesh, anyways. still, when i do a 5-2, for instance, id rather not have to 1) wait for the synchros 2) have the synchros absorb the friction and wear

on my old car, double-clutching was really a necessary to get it in 1st when rolling


dbclutch...4 lyfe!
