    Rev-limiter

    Can anyone tell me if my 09 WRX has a permanent rev-limiter?

    I noticed that it cuts out at red/yellow line, which is 6500 rpm, yet the tach goes to 8000 rpm.

    I thought maybe this would change as I put more miles on the odometer, but I'm up to around 3000 miles and still notice the limiter at 6500 rpm.

    Just wondering, as it'd seem there's 1500 rpm I'm sort of missing. (Not that I plan on running to 8000 rpm all the time.)

    Thanks.
    Too cold to ride... so I'll drive instead.

    You're gonna spin a bearing, experience valve float, and/or break something in your valvetrain if you ever run 8000 rpm on a stock motor. Just because it has the numbers on the tach it doesn't mean the car can do it stock.

    On top of that, you're stock turbo is gonna run out of unf long before you get to 8k. You're not missing anything. If you were to get a larger turbo, say an FP Green, then I'd say you'd be fine to raise it to 7250 tops.

    +123456^^^^^^^ to everything he said. Ever read the spun bearing threads. Revving that high, your just asking for problems. Plus like said above, boost runs out before 6K. STAY WAY AWAY FROM YOUR REV LIMITER, sheeesh, I dont go higher than5,500 rpms

    I guess that would explain the knocking and pinging I get every time I accelerate... JUST KIDDING!.

    Thanks for the advice. I'll get around to reading the spun bearing thread at some point, and hope I never need to refer back to it.
