Hey everyone, I'm still a new evo driver so I'm not sure what's normal and what isn't. Recently my 9 mr has been acting strangely when accelerating. I've noticed that when attempting to accelerate hard at speed, my rpms will climb about 500 units, but the car won't actually accelerate. The rpms will then fall back down and the car will begin to accelerate. I can't say for sure but it doesn't feel like the car is accelerating as hard as it used to at this point. When this happens I can see my boost gauge will go past the 1.5 mark and then when the car finally starts to 'go' the boost will fall back down to around 1.5.

Some other info is that I recently got my car serviced. I'd love to know why this is happening if anyone has some insight.

Thanks!

 

If rpms are increasing and the vehicle speed is not then more than likely the clutch is beginning to slip.

 

Your clutch is slipping.

 

You can do a simple test for the clutch, drop it into 5th with the handbrake on and slowly release the clutch, a good clutch should stall. If you're climbing 500 units it might be going bad but not that bad, in the clutch test if it keeps running then your clutch is WASTED.

What clutch are you running and how many miles on it?

 

100 % its the clutch ,

 

As stated sounds like a slipping clutch. What happens if u gently roll into boost vs just punching it? Do the rpms flair when u shift hard and high?

 

Deff your clutch man.

 

Ok, thanks a ton guys. I kinda figured it was my clutch, it's exactly what it feels like. I guess i just found it kind of strange that I didn't get the 'burnt clutch smell' when it happens.

I'm not sure how many miles the previous clutch had on it, the car has about 44k miles on it now. I assume the clutch was at the end of it's life when I bought the car (at 40k), and quickly finished it off while I was trying to figure out how to launch/drive he car lol.

I've only gotten one quote so far, and it's about $750 for the clutch, and about $1100 for the labor. Including tax and resurfacing the flywheel, it comes out to a little under $2000 -- does this sound about right to you guys?

I was also shocked to find out that the recommended clutch if I had over (I think he said 400 hp), was $4000. It was pretty humerous, when the mechanic was looking up the parts for my car I was hearing him mutter under his breath: "God damn these parts are expensive".

Anyway, thanks again for the help guys.

 

I would go somewhere that they specialize in evolutions.

 

It's just a clutch job, so you don't necessarily have to go to an Evo shop but I'd recommend a shop that's got experience with the cars and at the very least, a shop that has experience with modified imports and performance cars.

Do all your own research here and on Google, decide what clutch to run, then shop around for the best pricing. Ask locals where they'd take their car(s). Don't trust just 1 persons opinions, either.

The Exedy Twin is a pretty good clutch for a stock or nearly stock Evo. Feel free to PM me if you need a quote on parts.

 

Best of good luck choosing the right clutch for you!

 

1100 for labor? Make this your 1st project...

 

If he's got the tools, that's an option. A clutch isn't that hard and it's well documented on how to do the job. If he's got no tools, and/or is uncomfortable doing the job, it's best left for a pro.

$1100 is pretty steep, which is why I recommended finding a shop that knows Evos or at least modded Japanese cars.

 

West Werks in redmond bro, hit up francis. Its about 810 for labor

 

thats also true
