Default How many ap2's removed clutch delay valve

an1 running ap2 swapped slave for ap1 slave?

Clutch still feels strong and i have yet to actually feel it slip but doing a pull from 2-5th the other night got some strong clutch smells. Leads me to believe the clutch delay valve was letting it slip for a moment on each gear change.

edit: also, doing a pull in a single gear no smell so this also contributes to me thinking cdv. Still no slip at any time.





Derftuned remote etune really brightened up the mid range on this thing. Used to be like a light switch. Gotta Love that fresh tune smooth strong pull. Not even on the dyno yet :thumbup

The ap2 flywheel may be exasperating this issue. Maybe the clutch is getting tired. Figured id feel it slip first tho.

i had a friend with me. He was like s**ting his pants... i was like, 'meh. Lol.

I removed mine but still running OEM setup. Seems that OEM AP2 flywheel is very heavy. It has helped to remove it but its still possible to make it slip between shifts.

Soo you swapped to an ap1 slave? Or is it possible to remove the cdv from an ap2 slave?

Ya the more i thought about it, just seems like its never just one thing to make a cause / or "problem" more like the cdv + ap2 FW + plus added trq.

I simply removed the CDV from the AP2 slave.

On a ap1 flywheel I could see the clutch slip in the logs (could feel it a little as well) with the cdv still there. It did contribute to my clutch not being able to hold 4th/5th gear pulls (and eventually 3rd).

I have since removed the valve in my ap2 slave.

I removed mine as well but am thinking about going to a ap1 slave instead. If I push the clutch in slow it feels notchy.... if I slam it to the ground it shifts fine.

It feels like I'm not getting enough pressure and was thinking removing the cdv might have increased the volume of the slave cylinder and might be causing my problem. I also just replaced the clutch again, (2nd time in about 10k miles) OEM disk and bearings, act had pressure plate, and 10.5lbs flywheel both times.

The notchy feeling is probably due to the clutch fork contact points. The ball/socket at the slave connection, and the prongs at the throwout bearing connection.

The difference in volume should have no effect on the smoothness.

so how do I fix this. How can that connection change as the slave is bolted to the trans.
