I raced a cayenne last summer. On take off , I had him by about a car but after about a quarter he caught up and pulled away from me. They are quick most owner are a little snooty and don't want to run. See alot of them in West Bloomfield MI.
Had the TY out on afternoon at Detroit Speed. Old guy in a jeep SRT talked about swapping trucks. He was stating my TY was quicker than his jeep. He really didn't want to run it but kept insisting the TY was quicker. This is another high dollar one most owners tend to baby them.
The SRT8 is faster than the Cayenne. I think a stock well tuned Sy/Ty would run side by side with the Jeep. There's like 3 jeeps and 2 cayennes where I live and I tried to race 2 of them but the guys were too snob.
I didn't get a chance to run him from a dig, but from a 20mph roll an SRT8 will eat a stock Syclone's lunch. They trap 103-104 IIRC as opposed to a stock Syclone's 98-99. My truck ran mid 13s at 98 essentially stock so I know he didn't beat me for lack of a properly running truck.
