Dyno on engine after it has greater than 10,000miles

[Vreracing]

I have 13,000 miles on my Viper.

I was wondering if anyone has dynoed their Viper between when they had it new and after more than 10,000 miles. Mine seems a lot smoother and the performance seems greater now.

Do you see an increased in performance?

One other mention. I took my car to have the wheels balanced. Someone on this board recommended slipping the tech an extra ten dollars to torque the wheels down by hand. I did this and the car seems much smoother at speed. As big as the wheels and tires are it makes sense that they would be very sensitive to any irregularity in trueness that would come from a little different torque on the lug nuts.

For what it's worth, it's a good practice to always hand torque wheels on all cars, especially those equipped with disc brakes. Warping the rotors is one of the most common problems you'll see when the wheels are put on with an impact gun. The reliability of a gun to have a legitimate torque setting is minimal...for that matter, a decent torque wrench is not an expensive tool to have on your workbench. Around $50, and its nice insurance to check the torque every so often.
