A question for all you experienced stick drivers out there!

If one chooses to revmatch and shift without using the clutch, it won't wear out the clutch cause it will always be engaged and never slip. Also, if done correctly, it won't wear out the syncros cause the main and counter-shaft will be spinning at the same speed.

It is, however, slower to shift without a clutch, if you're just daily driving with a syncronized transmission.

In a HD truck with a non syncronized tranny, it's easier and faster to shift by revmatching, since you don't double clutch and pedal pressure is usually hard as fuck.

In a race application, sure, ripping through gears with total disregard for the syncros, is probably going to be faster but you'll go through trannies like a mofo.

I suspect Detox89 was referring to wearing out syncros, not the clutch.

^ yes thank you sorry bad with the whole mechanics of things lol the crews would always get pissed :S

The only reason i used it was for racing in the F2000 and the formula pacific race series were it was the only way to shift. Hope my input helped

I was going to call bs on you racing open wheel until I remembered who I think you are

Something good to know for situations like you have mentioned but it's not advised.

and for a video reference

WTF is this?

solution:
-just use your clutch
-buy an auto

i was forced to do it before when the master cylinder went on my old prelude

good times..

you're basically matching the revs and slamming it in gear, take the same principles but instead... step on the clutch. i think you'll find that its a lot smoother at the right revs and you use very little material regardless, its really the 1st gear moving from a dead stop that wears out the clutch... otherwise you're shifting incorrectly either letting the clutch out too slow or too quick

if u buy a dogbox you can shift without your clutch all day long, except its probably going to cost more than your car to buy the gearset.

it's definitely come in handy to KNOW how to clutchless shift. i've had my clutch slave cylinder and the hard pipe that goes into it at separate times in the past 2 years. i didn't know about clutchless shifting when the cylinder went, but i was able to drive my car to the shop after i learned about clutchless shifting when the piping went.

for most cars, there's a clutch switch right above the pedal that allows you to start the car. for my old celica, the switch is easily accessible by driving barefoot and your big toe just fits perfectly for the switch. at every stop light, coast to stop/turn off car, then go in gear+start car while holding down switch to start moving, then clutchless shift to get up to speed.

despite knowing it, i would never do it in regular driving.

Just use your clutch. If you use it properly, it lasts a long time. Better than risking a damaged tranny.
