Default CDV= clutch delay valve help!

hey yes i have searched lol. is honestly removing the CDV in the slave cylinder gonna harm the car in anyway, or is it just gonna make the car engage the clutch harder.

i read somewhere on here that if you remove it, its gonna actually make the clutch wear faster and or could do damage to the diff.

im not a crazy hard driver or anything i dont track it i just wanna be able to shift quickly without having slippage.

im going to be buying an 04. is the CDV really that noticeable? what is it actually doing, is it making the clutch slip or what lol. lmk please thanks.

there are so many diff opinons on this

thanks guys

It delays the engagement of the clutch so what ends up happening is that you release the clutch with your foot then hit the gas, but the clutch isn't totally engaged so you get some slippage and once a clutch starts slipping it takes a lot more effort to get it to stop so you actually get quite a bit more slippage then just the small delay would imply. So the CDV doesn't directly cause slippage but indirectly it does. The way to fix this would be to delay hitting the gas a little or remove the CDV.

As far as breaking your diff goes, you won't have a problem unless you are doing 7k rpm launches while dropping the clutch.

^ Yes, it basically becomes an AP1 setup.
The problem people's been claiming was that even after the CDV removal, some slippage during quick upshifts were present.
It's due to the weak PP.
I haven't heard of CDV removal causing major issues.

You may get a better feel, but won't be exactly like the AP1 because it has a lighter flywheel than the ap2s.

let me tell you..........when i did the CDV mod, it was a night and day difference......it grabbed so well that it chirped going into second and sometimes 3rds. But the damage was already done from all the slipping on the stock clutch cuz of the CDV, taht i had to replace the damn clutch anyways.

I'm turbo charged and i dont have ANY problems. Your gonna be alright as long as you dont launch like an idiot.

Yeah it won't be like an AP1 because the clutch is 10 pounds heavier in an AP2. I think the heavy flywheel is one reason they put the CDV in because it leads to greater shock to have a heavier flywheel. So just be a little careful with your shifting.

Like what's already been said, the CDV delays engagement of the pressure plate over a set period of time, so you're not getting the PP's full force until after the delay. Because of that, there's room for slippage if you're gunning it.

If you remove it, and you're always sloppy with your shifts (like 1000rpm off or something), or your always speed shifting, then yeah, you'll wear the clutch down more. If you've got your shift points down, you should be fine.

Personally, I recommend removing it. I had it done a few months ago, and love it.

You won't damage the diff unless you're launching the car and dumping it at high rpm.

I've considered doing this but was heard it's such a trouble to remove and people were saying that I should do it in next clutch replacement, along with lighter flywheel. I doubt I'll ever need a clutch replacement soon though...
