I tried it all the way up to 150 mph. The rev went past the redline (7400 rpm) and almost to the fuel cut off (7900 or 8000 rpm). The rev was around 7800 when it hit 150 mph and it got stuck there so I'm not sure if the it continued to go faster to around 151 or 152 when it finally cut off the fuel. The car did not shake at all but my car is also 2 1/2 inches low and I'm running on 225 wide tires so maybe that helped.
There is a slight error in the speedo and tach.... Car and Driver had the car clocked at 142 when the speedo said 150, and the tach is acutally about 300 rpm slow, which is not a bad thing.
