Not knowing what you consider as "regular shifting", this question can't be answered.
"Blipping" the throttle is a quick application of gas to increase the engine rpm to a point that it "matches" the speed of the spinning parts of the tranny that are connected to the drive wheels.

I rev match downshift as follows:

Begin to apply the clutch and move the shifter ALL AT THE SAME TIME. By the time your clutch hits the floor, your shifter should be just entering the next gear's slot. Now you blip the gas and release the clutch quickly. If you've match the revs right, this transition should be smooth. This can all be achieved in a split second. Timing of all these things is key.

 

Upshifting = shifting UP to the next gear, so yes, that's the normal thing

Blip = increasing engine speed while clutch is in, so once the clutch is let out and the car is in a lower gear the downshift will be smooth.

 

I made an assumption.
You know what that makes me...

 

i noticed that i have to blip on the throttle when i vtec to get the smooth shifts..if i don't..i always get the jerk. Does it mean that i'm shifting too slow and the rpm are dropping too low?

but then if i shift fast...the delay valve kind of kicks in and the clutch slips...so how are we suppose to shift smoothly on the AP2s when driving aggressively?

 

If you have to blip the throttle on an upshift, then yes, you are shifting WAY too slow. I don't know the correct technique on an AP2 to solve the delay-valve problem other than fixing the root of the problem (remove it).

 

I notice that if I add some extra gas to an upshift it becomes really smooth. But depending on how fast you upshift you will not feel anything. For downshifting will just take practice I'm still practicing how to downshift but I pretty much got it down. Pay attention to your RPM but after a while you know by instinct how much to blip your throttle.

 

1. clutch
2. next gear lower
3. gas
4. clutch out


is it wrong that i select the gear first and then give it blip?

 

This shows a good example of Heel/Toe shifting.

Uhhh... I don't really agree with this. Yes, learning how to heel toe is nice to know how to do, but when you are downshifting you are not always on the brake. What if you are on the freeway and you want to pass someone and downshift from 6th to 5th, you don't hit the brake, so how is rev matching pointless. I think that it is the only way to drive a manual car smoothly. Even my grandma can drive a stick, but without rev matching the car will jerk like crazy when upshifting or pull way back on downshifting. I'm just trying to say that rev matching is a critical part of driving a manual car and it definitely cannot be replaced by heel toeing in my opinion. Also, what do you think you are doing when you heel toe, you are blipping the throttle and rev matching on downshifts .
Basically to revmatch upshifts it is pretty natuaral because if you shift quickly then the rpms will fall to basically where they need to be for the next gear by the time you let the clutch back out. For downshifts you need to kind of know where the rpms are going to be at a given speed when you select the next lowest gear and take the clutch out. For example if you are in 4th gear doing 33mph and you want to downshift to 3rd then you will put the clutch in, shift from 4th to 3rd gear, blip the throttle so your rpms will rise to about 3300rpm and let the clutch out. You can feel if you gave the car too much gas or not enough on your revmatch when the clutch grabs. Just give it some practice and observe your tach/ feel the car when you are shifting and you will get it.

 

I guess "blipping" takes practice.

I have never had driving lessons so I have a couple of questions. Usually if I am downshifting it is because i am entering a corner, therefore I am applying clutch and brake and the engine and vehicle speed is dropping anyway. Why would I need to blip the throtle.

While technically it may be correct, what is the advantage? I can drive my car pretty hard, but don't "heel-toe" or "blip". Would I drive faster if I did?

Also I have occaisonally on high RPM VTEC upshifts not fully let up on the throtle. This seems to keep the RPMs high when I disengage the clutch and the next gear doesn't bog. It seems to work. Now is probably where you tell my I am frying my clutch or something. The car doesn't seem to react negatively, so maybe someone could tell me if this is wrong.
