Virgin Racing has sworn by CFD or computational fluid dynamics for the aero aspect of its car.  Technical Director Nick Wirth who also was involved with the Simtek team in the 1990s has said that CFD cuts down expenditure and is as reliable as wind tunnel testing.  But the poor performance of the Virgin car last year and in the three races so far has made John Booth the team Principal seek the services of Pat Symonds who along with Flavio Briatore was sensationally involved in asking Nelson Piquet Jr. to crash his Renault car to facilitate an Alonso win.  Symonds was banned from the sport but can now consult for a team and return to the pit wall in 2014.  It is hoped by Virgin that Symonds can provide the required turn around by identifying the problem areas.
