He's just talking about kicking the clutch while climbing the revs, no shifting.

Kinda pointless, you're kinda just essentially braking the engine with the clutch back down to where you were. I'm sure you can apply some conservation of energy principles to show that it's not doing anything but I'm too lazy lol. Thinking about it though...

You're burning fuel to accelerate a spinning mass with no real load. That energy is basically stored as a rotational inertia and nothing more.

So when you engage the clutch back, the only energy you gain is the small amount from the increased inertia with a lot of loss of energy to heat via friction in the clutch assembly. Whereas if the clutch was engaged this whole time, you're sending the power from the gas directly to the wheels and not losing any energy to heat through the clutch.

this is a pointless thing to do, and it will only do damage to your vehicle.

ya our svts don't have the tq anyway so it'd prolly take a tenth or two of a second away and just be hard on your clutch

Yeah, something like that. I'm going to try it once or twice next week and see what happens.

By NOT accelerating if even for an instant the suspension as well as other key factors will "relax" and this is not a good thing when talking forward acceleration across a specific distance ie 1/4 mile. Anything that prohibits forward acceleration will show in your time slips, this includes lifting or clutching. Unless the power increase at the higher RPM that it "jumps" to after taping the clutch while accelerating under WOT is sufficient enough to cover the lack of power during the pedal depress duration as well as having the capability to produce more power than the original rpm curve, then NO this is not beneficial to your drag times.
You also might want to find out where your car makes the most power, at what rpm does it start and where does it end. If you go playing around in your power band area and don't know what your doing, then you will suffer tremendous losses while drag racing.
Nope I'm not talking about double clutching, and I could be wrong, but you are the first person that I heard that calls double clutching and powershifting the same thing (IIRC they are two very different driving techniques). And I would like to re-quote you on this;
" Anything that prohibits forward acceleration will show in your time slips, this includes lifting or clutching. Unless the power increase at the higher RPM that it "jumps" to after taping the clutch while accelerating under WOT is sufficient enough to cover the lack of power during the pedal depress duration as well as having the capability to produce more power than the original rpm curve, then NO this is not beneficial to your drag times."
^^^Your explanation is kind of what I was looking for. I'm going to PM to see if you can explain me this more in detail.

Thanks, that's the most helpful post so far. If you ever run for president, count with my vote
