got an '09 S2k with 3800 miles. the clutch slip in this car is ridiculous when shifting in spirited driving at redline. i often get a good slip going into 3rd even after i wait a blip of a second after releasing the clutch before hammering the gas. is the clutch system in this car designed to slip? i am thinking i should get rid of the CDV right away, as it is nearly impossible to drive hard with a delay in the clutch system. does the clutch not grab well from the factory? i'm just not happy with it. been driving a stick for 25 years, and this is the first time i've just had something that seems wrong from the get go. any solutions after 10 years that make this problem go away? seems no cdv is the first best thing to do ... suggestions? thanks!!

 

Mine used to do that when I'd get on it hard back around 50k or so.
At the same time, that's when I used to be abusing it certain nights on a dark road off the beaten path.

Currently at 128k, and haven't experienced slip in a couple years.

 

Once the CDV is gone you should be golden.

 

i would say its a combination of the clutch delay valve and the drive by wire system

 

Just swap your AP2 slave cylinder with an AP1 slave. That's what I'm going to do when I get my stage 2 competition clutch with lightweight flywheel

 

^^^easiest way with proper fit and function, plug n play

 

i crossposted this to another forum, and was told that it's my driving style? after 12 manual transmission cars, i find that a bit suspect. now, i have also heard that it is the clutch and heavier flywheel that causes slippage. i happen to think it is the CDV, simply because it allows the plates to spin against each other right at the engagement point, like it would if you kept your foot a bit on the clutch, and then the power of the engine at higher rpm overcomes the potential clamping force of the clutch plates. in any case, i am trying to see what the next step should be ... change how i drive (ridiculous imho) or remove cdv ... ? i think i can disassemble the OEM valve and remove the delay mechanism .. ?

 

Replace your AP2 clutch slave, with an AP1 clutch slave. do not attempt to remove the CDV from your AP2 clutch slave

 

CDV was added to stop diffs exploding wasn't it? Should it be as noticeable as this though??

 

dont believe everything you read on s2ki...thats the same website that everyone swears by the 100 dollar ebay exhaust on

 

i have an extra AP1 slave lying around somewhere if you want to rebuild the seals lol

 

get a lighter flywheel and you should be fine.

 

You CAN remove the CDV from your AP2 clutch slave. You just need the right tools to get the snap ring out, then you are good to go.

I did it with much success. Made a very big difference.

ur ap2 flywheel is heavy as **** too i think like 22lb the ap1 is 14lb.

u could get used to it/adj the way u drive seems like u wont do that though.

i would suggest get rid of the cdv or get ap1 slave and get an ap1 flywheel and you should b a ok

 

I would love for you to bring up ANY post from s2ki backing up what you just said.

I read a lot there and on many other forums and have only come across a few posters there that have questionable tastes, but NONE of them talk about any generic exhaust from ebay.

 

im not going to dig through posts to prove it, because quite frankly, i dont give a **** if you believe me or not, but its there and its been mentioned on a few occasions...you can dig through all the **** if you want, but i have better **** to do than prove a point to a complete stranger over the internet...just saying

 

 

how does a clutch go bad at 38,000 miles? Mine was still good at 70,000 when I took it out and I had 100 horse over stock for 10,000 of those miles.

 

according to his original post, he only has 3800 miles...im certain its his CDV, DBW, and heavy *** flywheel that hes experiencing

 

consensus seems to be that basically it's the pressure plate and flywheel combo that prevents effective high rpm clamping with stimulating / smooth driving / shifting. oh well, expensive, but a solution is a solution.

 

Don't get rid of the CDV, it was designed to eliminate drive train damage. Replace the pressure plate with one that has more clamping pressure.

 

No.... it wasn't... lol

 

^yes. It was. But getting rid of it does improve clutch life. Id rather replace a diff than a clutch. Cheaper and easier.

 

OP, remove the CDV before you go and replace clutch components. That will take away the slip. The S2000 isnt the only Honda with a 8K RPM limit and a heavy flywheel/light clutch. H22s, K24s, and B18s don't have clutch slip from the factory. It's just the CDV that's making it slip.

Either go with an AP1 slave cylinder or remove the CDV by taking the slave cyl apart and taking out the restrictor.

 

Start with the CDV delete. If that doesn't fix it, get an AP1 or lightweight flywheel and a stronger clutch. I had the same exact issue and ended up getting an 11lb flywheel and Comp stage 2 clutch. I still have the CDV, but no slipping is present.

Doing the clutch yourself is not too bad if you have mechanical experience and tools.
