Spot on. When I was younger & sillier I used to do forwards to reverse burnouts and reverse to forwards burnouts on a Komatsu forklift with a 2 speed crashbox. On a wet concrete floor or on dirt & gravel. Kids, don't try this at home - The trick is to stomp on the clutch & the brake pedal at the same time by twisting your foot sideways. You need to lock the brakes up & skid, this stops the gearbox internals from spinning. Now you can shift gears from forward to reverse without crashing them, even without synchro. Then you floor the accelerator, dump the clutch, and listen to the applause. :thumbup: For extra fun, when the bosses weren't around we'd pour diesel over the wet floor. I could do a Knightrider / Bumblebee / Hollywood style reverse to forwards turn & burnout that way but if I slid past the edge of the wet patch it was a worry. With no seat belt to hold you in place you'd be flung off the side, gravel rash FTL I tried the same tricks in some cars that I didn't like much but the Forum guidelines prohibit any discussion of such foolish behaviour. :nono:
Reliability Yeah I've had a car like that too. It either runs for 10secs, or a 1/4 mile before it breaks down again.,
I only use the clutch in my Rolla to get started and sometimes into second if I need to get moving in a hurry. This is only cause the slave cylinder leaks when I put my foot on the clutch and I go through less fluid if I don't use it.
Just to be clear I am not saying that double clutching is a bad thing, each drives their own way. I am just saying that double clutching in a 1/4 mile race application is not the done thing because of the short amount of time involved. I am also saying that shifting without clutching in a 1/4 mile application probably wont be done by any real racer because where and when the box wants to shift is not within the rev range that a racer would want to shift in. This would mean that the statements made in the "Fast and the Furry-Assed" are wrong! . . . how could they lie to people in a hollywood film? that never happens.
"Now me and the mad scientist have got to rip apart the block, and replace the piston rings you fried!"
ofcourse on motor bike gearboxes and i believe sequntual gearbox, you can't do this because thier is no nuteral betwenn gears, well you could but the gearbox will not like this one bit. and not advised
It has nothing to do with where nuetral is and everything to do with not having syncros. Moto's, most sequential box's, older say pre 70's cars and most trucks have dog gears, so with the right timing you can shift without fear of damage, with bad timing you will still destroy them, last week I changed 3 engagement rings in an 18 speed Roadranger gearbox because the driver hasn't got the timing good enough on his shifts. You shift your normal box without a clutch and you ARE doing damage to it. But hey, Z32 boxes are only $1800us from coz so why not.
I used to think I was cool and heel-toe downshift while braking - without the clutch... around town... Then my gear shifter fell through the floor 200km from home! It was unrelated to the clutchless shifting (probably more due to the fact it was a Kia) but it made me realise it's just not worth the cost of fixing due to the extra wear and tear unless you're very well practised at it and do it peroperly.
heal and toe without clutch? am i missing something. I thought heal and toe was so that you could use all 3 pedals at the same time? http://www.youtube.com/watch?v=JliPGde8jMM Why would you need to heal and toe if your other foot is off on vacation? do you only have 1 leg?
Bejeebuss M8, being a driver, I'd have to try mighty hard to break a Bushranger...... If you had to do that repair to an 18 speed,then Id hope that particular driver was moved back to a more appropriate jigger with a synchro box.... better still an auto....... L8r E
i still suggest using the clutch regardless of what box you have, but its possible to change gears without the clutch.
