no cdv in evox 2010?

I was @ Akuma Motorsports today getting some parts installed. The owner drives a 2010 X (and they are now getting into the evo scene hardcore) and he already put in a lot of work on his ride. I figured that since I'm at the shop, my minus will would be to get that clutch delay valve thing removed. After getting into a conversation with John... he mentioned that when he went to do this on his 2010 X, there was no CDV. Then he mentioned how funny it was that the 08/09 models had it. Meh?

I noticed a huge improvement in shifting after I got those under-hoods put in today...
It feels more precise than just running the works SS & console bushings & a 490 counter-weight knob.
Can't wait to redline in up when getting the piping installed & tune.

Maybe some 2010 owners can chime in about that pill removal. I know half of you guys already have a new master and clutch so this only is a question for the stockers haha

that would be quite a difference considering they used them as far back as DSM's. why start with 2010s?

also they're there to protect the drivetrain under normal driving.

its snake oil...
the evo 8-9 guys were all over removing the clutch line restrictor pill mod for years. Here's what i found out... Its a ONE WAY restrictor.... I believe this is true since the same goes for aftermarket restrictors like the one im running w/ my Tilton twin disc.
meaning it only restricts flow one way.
1) it doesnt even come into effect unless its a quick/major clutch movement. (light movements are unaffected
2) it doesnt affect PUSH (or disengagement). So that means you can still shift fast.
3) it only affects the pedal coming back (engagement). In an abrupt engagement, it restricts flow allowing a SLIGHT slip when it re-engages to prevent drivetrain shock by dumping the clutch.

that difference in "FEEL" that you experience? well thats the engagement part. THAT has nothing to do w/ your shifting. Disengaging does(pushing the pedal in).
The only reason i can see why someone would still want to do it, is because they want to modulate the release 100% w/ their foot. But again... that affects your launching. NOT your shifting.

as for the solid shifter bushings... yes those work to an extent. You remove the play caused by the rubber ones obviously. A solid front mount does wonders as well. More importantly a good transmission oil plays a huge part.

I have a 2010 and yes it still has the pill. Mine was stuck in the slave, but I removed the slave and tapped on a surface and it came right out. Makes a world of difference, seriously...

actually i'm experiencing a hesitation in disengagin quickly with my aftermarket twin disc. it's been bled several times since install. i have the ams clutch line waiting to go in with hopes of that solving it. i also experience all the engagement characteristics as well.

Not snake oil, removing the pill is very beneficial. Yes, 2010's do have them.
