70K, no complaints here

 

i'm at about 60K and i have a feeling my clutch may be heading to greener pastures. I have a feeling the previous owner wore it out.

 

third post today about CDV.... i'm leaning more and more into removing this thing as i feel no one likes it here... i always here people removing it...

i always have in mind that if honda added it to later models... it's there to add more reliability to my car... i'm an advocate of staying stock as much as i can... honda put a lot of research and development to come up with these settings(suspension, gearing, motor, exhaust, etc) so i plan to take advantage of that(plus it's cheaper to keep it stock hehe) and enjoy it for what they intended it to be....

but you're saying that your clutch might have lasted longer without CDV...

what gives???

 

The CDV stands for "Clutch Delay Valve" and that is exactly what it does, it delays the engagement of the clutch. It is a little device inside the Slave Cylinder that restrics fluid flow to a slower speed. By doing this, it lives up to its name and "delays" the clutch. It is used in a lot of modern cars now. As you may have seen on s2ki, there have been reports of s2000's (especially earlier NON-CDV vehicles) damaging their rear differential or axles and other driveline components on hard launches. This is because the rapid engagement shocks the drivetrain and that can cause damage to components down the line on the way from the engine to the rear wheels. By delaying the clutch engagement, Honda's rationale is that it will minimize damage down to driveline components. Unfortunitly, the CDV causes the clutch to slip a bit (since the fluid in the clutch slave cylinder is delayed) in order to do this. Although it serves it's purpose, it does so at the expense of shorter clutch life. The clutch is a wear and tear item (meaning it's not replaced under warranty, much like brake pads) and the drivetrain components (such as the differential) are not . . . so it is better for Honda financially for your clutch to go out early than it is for you to blow a warranteed differential, axles, et cetera.

However, there are LOTS of AP1's out there running just fine without the CDV (it was implemented in late 2003 s2k's and up). The accepted reasoning on s2ki from the most respected members is that if you know how to drive and don't ask the car to do things that are in excess of the cars mechanic limits (or your driving limits) then you won't have drivetrain problems and the CDV is only going to limit clutch life. However, if you are driving very aggressively and spinning the tires purposely and don't have a good understanding of what you are doing . . . perhaps a clutch change (while expensive) much be cheaper than you blowing up something more expensive.

For the record, I removed mine a long time back (probably about 20k miles ago or so) and my car is running great. However, I don't launch the car. In my mind, it seemed the excessive slip on redline shifts was more of a burdon. I now have no CDV and the Hardtopguy Clutch Kit and is all grip and no slip

Hope it helps!

 

80k slipping a little bit so i changed it

 

50k and just upgraded to a ACT clutch n flywheel Not bad milage for a MY00

 

Just hit 47000 On my way to work . The clutch doesn't feel fantastic though if I must say. My engagement point is almost at the top of the pedal. It still grabs relatively hard though so it could very well just be my paranoia.

 

I bought the car new and my OEM clutch lasted for 18k miles.

That does not necessarily mean the clutch is dying. Perhaps a clutch bleed or a pedal adjustment could help? Just throwing it out there. If you search, there are various tests you can do to test the ability of your clutch.
