I heard that having a CDV makes a diff in response time at the strip, and is not helpful to have while daily driving. The only thing I can think up is that the CDV does not let you chirp 2nd or 3rd gear, can someone explain to me what the purpose of the CDV is. Sorry I am pretty new to S2k's. Help me out guys.
I have an 07 by the way.
Thanks,

 

The CDV limits shock to the drivetrain, by slowing the clutch engagement (it's a clutch delay valve). The AP1s do not have a CDV.

In casual driving, many drivers wouldn't even notice it's there. Repeated hard launches and hard shifts, trying to "chirp the tires", will break the drivetrain (usually the diff). It's just a question of when. Removing the CDV help you to accelerate that process, if that's your goal.

 

CDV= nanny for those can't drive the car.

it's a delay valve honda put it so noob would break their diff(or whatever in the drivetrain) doing a noob launch

there's about 200 thread about CDV, so read up

 

The CDV makes shifting much more vague.

I took mine out, but I the clutch still slips a bit on fast shifts, though it's much better. I think the OEM pressure plate also allows some slippage, and the two work in tandem to reduce drivetrain shock on AP2s.

 

I had a Competition stage 2 clutch installed.

Left the CDV, but get no discernible slippage whatsoever. It will now bark the tires going into third @ 58 mph.

 

the oem pressure plate slips on a brand new car. Act ftw!

That's a good post. Thanks for the ref.

 

Chirping tires on gear changes is a sign of poor shifting. You're breaking traction and upsetting the car's balance.

 

wow, i had rs-2 in the rear and i could chirp mine pretty easily. and launch at the strip, i had consistent 1.9 60ft with my stock tires and stock clutch.
