RPMs for 04 GTX SC

[NHGTX SC]

Evening All:

My 04 GTX SC top end seems to be 7400 +/- 100. Hitting 60 MPH on my Garmin 76CS.

I bought the SD last summer and for the life of me thought that she was running 8100-8200, when I aquired her. After putting another 15 hours on her (total of 45), had the local dealer replace the wear ring as the RPMs were running 7600 approx. This was done at the end of the season, when she was winterized. No mention was made to me regarding any concerns with the impeller.

I had also had Jerry's metal washers installed and the SC upgraded to the 06 specs.

Running 93 octane, and Denzo Iridium 24's.

Also have a Riva BOV.

SD owners manual states that the rev. limiter is set at 7300 +/- 50. (page 90).

So...was I dreaming about the 8200?

Thankx...

I think 76+7700 is average, thats what my 2003 GTX SC hits with a rr ecu and Solas 14/19r.

my 03 gtxsc stock turned 7600 rpm unless ur 04 was modded with a rxp ecu on it, it won't turn much over 7600

Hi:

Other than the stuff I noted in my initial post tonight, my GTX SC is stock.

Oh...oil level is mid-point between the bends in the dip stick.

So..no one is getting 8200 on a stock GTX SC.???

Have you checked to see what the turning torque is on your SC?

Hi Jeff, welcome to the forum. 7600-7650, and 7700 are max rpm`s for the 04 GTX SC. 7600 is normal limit in the heat, you should see 7650 in the cooler temps, and 7650 I think is the soft rev limit as 7700 is topped out.
You will not see 8200 on a stock 04 GTX...PR...

Good Morning All:

Thankx for the replies.

Gold: You mentioned the "turning torque" of my SC. Ahhh..how would one go about measuring that?

The reason I ask is that the shop that worked on her last fall is scheduled check out my RPM concerns this Monday.

I'm just wondering if I am overly concerned about this. She was turning a true 7600 before the washers were replaced along with the SC upgrade.

Other than that... she runs really sweet. Such a different ride from my Polaris Virage TXi. My wife even enjoys it.

You remove the air intake going to sth SC. Remove the valve cover and lock the cam sprocket in place. You can use a clean screw driver. Then take a in/lbs torque wrench and measure how much torque it takes befor the clutch slips. I belive it should be between 50-90in/lbs.
