The CDV was specifically designed so that Hyundai Santa Fe's will beat your ass whilst you shift into second hard and are greeted with this nice, prolonged slip, instantly wearing 100 regular starts from your clutch.

 

i absolutely disagree.

i do NOT drive hard (25k miles on original rear tires and 35k on front) but the CDV was an absolute annoyance. driving like a granny maybe one does not notice it but with ANY moderately quick clutch takeup and you feel the slugginess and lag in engagement.

my opinion, the cdv was an over protective nanny response to people thinking their AP1 were drag racers.

for a normal driver, the cdv is not a necessity

 

smurf2k,

Actually, I tend to agree with what you're saying. I'm truly not a fan of the cdv, and I'm glad my car doesn't have one.

My point was really to the OP - based on his stated use in drag racing. Removing the cdv will definitely increase shock on the drivetrain, a known failure point when subjected to that kind of use.

 

And stating a car *will* chirp/bark the tires when shifting is not.

 

The action of CDV must vary from car to car because I rarely notice anything funky about my shifts, even in spirited driving.

I had an AP1 before and I can and have ripped off similar spinning-wheel clutch drops from a stop. Once in a while I get a vague 2-3 powershift but I attribute that to a stock pressure plate and a little clumsiness. I've raced plenty of 1/4 mile and auto-x so I'd know if MY car was shifting funky.

[QUOTE=Saki GT,Aug 27 2009, 10:17 AM]Having driven CDV S2000s and BMWs, and listened to people complain about the CDV in both, I've come to the conclusion that the CDV isn't the main culprit - it seems to be deficiencies elsewhere, like a weak PP in the S2000 or just a driver that can't shift well in general or who can't adapt to the car.

 

meh too brahhhh

 

ou818, Clutch slip after enagement (like mashing the gas while rolling along in 5th gear) is not the fault of the CDV. All that does is slow down the release of hydraulic pressure, like a one-way line restriction, when you let the clutch pedal up. It doesn't change the absolute pressure or spring clamping force, just the rate of engagement. It doesn't come into play at all after the clutch is fully engaged.

 

I know this. That's why I never suggested it was the CDV. My best guess was, since my clutch still had some life in it and my pedal had some resistance up top, the slave cylinder was damaged/faulty.

I left my CDV in and installed a new slave with my Competition stage 2 clutch kit. My clutch now grabs fast and holds hard.

Before it was broken in, it was more like an on and off switch. Killed the motor and unintenionally squealed the tires a few times after I first got it
