Has anyone noticed that once you put an intake kit on your P5 that taking off from a stand still is smoother?

I'm still stock but was wondering if the engine smooths out with an aftermarket intake.

 

why do u propose an intake would smooth out take off?

 

I never noticed a jerky take off before or after installing the cold air
intake. I'm driving a P5 manual transmission.

 

Stop granny shifting and double clutch like the real street racers?!? I thoght the car was smooth anyway I just think that its a quicker response.

 

What does the term double clutch accually mean?

 

I am clueless it was in the movie Fast and fureous I didn't get it the movie either. I know that in a semi you clutch to get the gear out then clutch to go to the next gear (double clutch)in through 12 gears thats why the are so damm slow and fun to pass.

 

lol. Considering that double clutching has nothing to do with up-shifting. But I knew you were joking anyways.

 

When down shifting you use a double clutch technique. However you need to know your RPM shifts and feels very well. Example: You're in 4th gear. Instead of downshifting to 3rd and then to 2nd, you release the clutch rev to where you would normally change from 2nd to 3rd [ie: 6500RPM's] down-shift to second. Thus it allows you to skip having to downshift through the 3rd gear. It's a little complicated to explain when typing it out, but this is my shot at it.

EDIT: I'm gonna disclaimer this. I'm not gonna be held responsible when someone pops out to try this without doing more research and ends up blowing pistons through their hood .

 

You don't have to be skipping gears to rev match when downshifting. Double clutching doesn't really help in cars that have syncros ... you can do the same thing (blip throttle) without letting the clutch out in neutral between gears.

Basicially, you try to match the engine speed with the speed of the driveshaft so the car stays balanced when you put it back into gear (no nose diving).

This has been discussed more than a few times on here .. maybe it should be in the FAQ It's also discussed in Skip Barber's book (and probably many other driving books) for those who care to read in more detail.

 

Okay okay. I give up (laying on the floor face down)

The reason for my question is from a prior experience. A friend of mine had a 94 Legend 6spd coupe and we took the intake off to just see what type of intake volume this car had. The car smoothed out (accelleration wise) and drove like it had 20k mi on it (actual 101k mi).

My 5spd P5 bucks really easy. This is my first Mazda, all my Civics and my current Crx Si are smooth as buttah. But my P5 takes off like it is choking.

Thats all! Thanks for your time guys!!!

BTW: I autocross and ice race (i.e. I can drive). Basically my p5 is just harder to take off effortlessly

 

Damn that was a good way to put it. Thanks man.

 

Just wondering why are you guys talking about all these double-clutching, rev matching, gear skipping stuff when the problem that P5freak has is NOT about downshifting?

IMO, it has to do with the lack of power/torque when the RPMs are really low, like 1000-2000. Seems that the torque curve has a "notch" in it. So P5freak, you might wanna step on the gas pedal more before slipping the clutch in for smoother starts

 

Finally a response to my question! Thanks Douggie!

That is probably my subliminal problem. All my Hondas didn't need this extra blip of slippage.


Also to "theMan". I won last years 6 hour endurance ice race in my CRX Si. You don't lap 34 cars 7 times in 6 hours because you suck. I am simply asking an "educated" group of enthusiasts there opinion on experiences I have had with my P5 (in comparison with my Hondas).

 

I think what you might be refering to is the "bucking" that is described on page 2 and 3 of this topic.

It's the price you pay for short, aggressive gearing and a reletively torquey small-4.

 

It's just a matter of habit. My mothers 99 Civic has very light clutch and after driving her car I feel uneasy in my Pr5. You'll get used to it, Mazda clutch/transmission are not smoothest in the world.
OR, you can look at it from different side:
"Mazda Protege 5 is uncompromizing performance machine with minimum level of comfort. Huge amounts of torgue almost rip transmission out and make car jump ahead as frog on steroids which is followed by uncompromizingly modest acceleration"
