Apparent loss of power

[peter.sellers]

I feel as if the car doesn't put out much power as before.

Yesterday I was revving at 3K on 4th and I hadn't even crossed 40mph. I shifted from 1st through every gear to 4th at 3K. The engine was still kinda cold though. Could that be the reason? I cleaned my SRI air filter a few months back, so I am pretty sure that's not the problem.

A couple other things are - my stock RMM is starting to get flaky and I think my clutch is worn out slightly. Don't know if these could be the culprits.

Looking for advice on what to check.

sounds to me like a slipping clutch...RMM wouldn't effect power, just how it's put down and if it's going bad I would suggest you get it replaced asap, wouldn't want that to give out cuz it would cause unnecessary stress on the other 2 mounts leading to a drop motor..

Sounds like a slipping clutch. In 4th gear at 3000 rpm you should be traveling at around 50mph if you have the OEM tires (215/45/18) based off this gear calculator I used.

Yep, the math works out to 48 mph at 3K rpm in 4th on stock tires. If he's not there or very close to it, the problem just about has to be the clutch slipping.

I am doing ~48@3K rpm in 4th. It does feel kinda soft though.

Maybe the wear has begun. Need to get this looked at. Can I make any adjustments? Or is replacement the only option?
