2012 WRX w/Cobb sf intake on stage 1 issue. Worn clutch or boost leak?

My car seems to rapidly rev up around 4000 rpm but I don't move noticeably faster when I floor it on 5th gear . I'm thinking it's my clutch. What do you guys think and if it is the clutch, any referrals for getting this fixed and how much? I've done a good amount of hard driving and am almost at 40k miles on the stock clutch. Also, I'm thinking about going with a stage 2 plus clutch.

I also meant to say that I'm running on the stage 1 economy mode map as well.

 

I found your problem.

If you do want/need a new clutch, NF can do that for you.

 

2012 and clutch is out already?

 

Yep. Ikr

 

If you are leaving the car relatively stock, I would keep a stock clutch. They will last longer, and be easier on the tranny than aftermarkets. I would rather swap a $300 clutch than a $3,000.00 tranny rebuilt. There is also better places to spend your money than on a aftermarket flywheel as well, in my opinion, specially on a basically stock car.

 

It's your clutch, get in contact with NF. I'd recommend a stock replacement...I went with the Exedy stock replacement and I'm stage 2.

 

Oh yeah? Would you recommend a new flywheel as well? Noob question, but how long does the flywheel last compared to the clutch?

 

Flywheel can be resurfaced for a few dollars. It shouldn't have to be replaced at this point.

 

If you burnt the stock clutch in relative low miles then I suggest going to stage 1 Exedy. A little stiffer pedal but not bad at all. Depending on how your old clutch went, another oem replacement will most likely do the same.

 

Thanks. Do you know how much it would cost to do this work plus the parts for this at rs motors?

 

I'd look into what Xluben said a little more deeply. You shouldn't be flooring your car while at low RPM in 5th gear unless your want a reason to rebuild your block. Its very likely your clutch is just fine.

 

Huh? I was on the highway on 5th gear.

 

You can be on the highway in 5th gear, but still at low rpm. Flooring it in 5th gear is not a good idea. Downshift if you want to gun it.

But what do I know... Carry on.

 

I heard flooring the car in 5th gear is the new thing.

 

From 45 mph

 

What's wrong with flooring a car in 5th?

 

I may be incorrect but from what I understand, 5th gear is the overdrive gear so when you floor it when at a low rpm, your engine is at peak torque too early in the long gear. The engine is essentially working against the transmission. Flooring it in 5th should be fine as long as your aren't in the low rpm range. But then again, what do I know.

 

Nothing inherently wrong but that is obviously when there is most load so the clutch is most likely to slip.
Also, with low rpm the oil pressure will be low and with high load from top gear makes the turbo spool extra early which could possibly cause oil starvation. On a stock car its probably not really an issue but still something to think about.

 

2012 and clutch is done? Sure you're not riding the clutch?

 

Honestly, I'm not sure anymore. It still runs fine. Sometimes when I'm on 3rd and give it a good amount of gas, the revs would momentarily stay in the same spot, then increase, then stay in the same spot. All of this while pressing down on the gas pedal.

 

I'll record of video of it soon and post it up. Hopefully by the end of next week when it gets warmer.

 

Definitely sounds like a slipping clutch to me.

 

Thanks everyone for the feedback. I'll try to post a video soon with the issue.
