From the ROSSA forums:
Nic Case will be running his car on Jan 16th at the Ford Arizona test track. He is pretty confident that he will get 200mph or more. In the mean time I am continuing to prepare my rocket car and will be testing it in Jan or March, depending on weather. The planned speed is 180-200 and 220mph in stages. Also on the horizon is Brett Smith who is building a new turbine car with planned speeds of over 200mph and another team in the UK are building a twin turbine car for 200mph plus. These are only the ones I know about.
It looks like its going to seriously kick off in 2011 and ROSSA will be at the very heart of it all
