Power Shifting

[izwar]

My friend and i had an argument over what it was, so what is it? and do you really need to do it in a straight away race?

power shifting is the art of shifting a manual transmission withouth liftinig the throttle. it isnt necessary and can be damaging to the the clutch pad. unless you are running heavy duty clamping pressure plates and upgraded discs it is really more harmful than helpful. an uprgaded clutch assembly will be able to handle the power transfer of the power shift with ease and can save you some precious time when shifting.

Isnt it simply not touching the clutch and slamming the shifter into the next gear...??

No clutch just slammed it into gears? what the heazy!

Actually you can probably do that if you match engine/wheel speed EXACTLY ( like within 10rpm) so that your gears will mesh without one rotating faster than the other. It sounds possible. But I doubt nobody is that coordinated, especially in full throttle action where +10rpm happens in <0.01s.

The clutch is just an instrument that slips purposely to match engine/wheel speed. If you are enough of a badass you don't even need the clutch man, unless for starting off in 1st.

in a non synchromesh transmission with straight cut gears(racing transmission) you can do this without clutch. i would advise against in a synchromesh car. People in racing cars do it frequently when up shifting with a racing transmission. Also FNinjaP90 a clutch is what transmits the power from the cranshaft/flywheel to the transmission.It isnt an instruments which splips purposely, It only slips when you let it. Unless your clutch has sustained heat damage or isnt clamping properly it should never slip once it is fully engaged. Which is why manual transmissions are more efficient than automatics because the torque converter isnt always locked up and has slippage.

Yes I know it is not supposed to purposely slip, but it is allowed to slip when you don't match rpms right(etc 2700 & 2900 or something). I know it is to transfer energy but its engaging and disengaging mechanism is for matching revs if you don't get it perfectly.

Does anyone know about the new CVT? Continuously variable transmission? That would be so awesome for racing since you can just continuosly alter your gear ratio while always staying in your engine's sweet spot.

Damn.........no clutch huh........shiet I'm still a rookie I guess or I'm too poor don't wanna break N E thang....these darn cars cost an arm or leg to fix shit...oh they're fun though..
