What is dumping the clutch

it really depends on what you want to wear out
if you let out the clutch slowly, you are waering out the clutch becasue the engine is spinning at one speed and the transmission is spinning at another speed and you are slwoly mating them together..so by slowly letting out the clutch you are alowing some friction to burn the clutch a little..wear out the clutch
if you let it out fast, you reduce that clutch burning and immediately mash the engine and tranny together thus forcing the tranny and engine to spin at the same speed. usually that means a shocking jolting type of force onto the gears of the transmission and axles...so then you would wear those out faster

the key is finding the perfect balance between the two extremes to manage what you want to wear and how you want to drive

this sounds like something to be done in a rental car :Q

In that case, wouldn't it be better off to wear out the clutch than the engine/tranny?

A few years back a friend of mine had a Cadilac (one of the 300 hp northstar ones) for a few days for a job he was doing. (not his car basically) We went to drive it around one night. We're in a parking lot in nuteral (auto transmition) He starts reving the engine. He revs it about as high as it could go then he shifted into drive. I was in complete disbelief that he did this. Before I could even get out a WTF! the car lunged forward and made a horrible noise. He quickly stopped and the smell of burnt metal flooded the car. It still ran so we went home. I couldn't believe he was this dumb. I bitched him out some and he said "I didn't know that was bad. I just wanted to see how fast it was"

Even though the car was an auto, this seems to be a similar thing to clutch dumping.

As long as you're shifting at the proper RMP and you're pushing the gas pedal properly, it doesn't matter how quickly or slowly you do it. Just don't touch the clutch unless you're shifting. Riding the clutch and glazing the clutch plate is a bad thing, mkay?

so are neutral drops at redline

I know :evil:

Ok, would this be considered dumping the clutch, normal upshifting, from like 3rd to 4th at around 3000 rpm and releasing the clutch really fast?

well, what i usually do with my car is (its an audi a4 quattro=all wheel drive), i usually use my left foot for both the clutch and brake pedal and right foot for gas pedal only. i only do this at 3rd and upper gears. lets say i am cornering, i keep my right food on the gas pedal (i dont release it at all), then use my left foot to touch the brake pedal. you have to be very careful with this though, or else you'll probably stall the car or hit something lol. well anyways, after touching the brake pedal and 3/4 done through cornering, i release my foot from the brake pedal and wooooooshhh, it flies

Hard on tranny, driveline, etc.

you forgot to mention .... with the windows rolled down, and some badass rap music blasting from a 500W RMS system

It'll do more than chirp if you have any decent pressure on the gas pedal...or should, anyways. Depends on the car.
