Water/meth almost cost me an engine, please be careful. I ran the same times with it and out it too. Running 11's in a Crossfire or SLK is in the expertise of the driver. Lots of practice or luck is what it takes unless you've set up the suspension for drag racing. I could never leave hard without spinning or getting some rear axel hop. A 1.8 60' was rare for me. My 11 second run was because I iced the entire top of the engine as well as running the I/C pump and spraying the heat exchanger with water. I ran a bunch of 12.0xx's then parked my car and iced for an hour. That's when it happened.
