Joospeed scores at Surrey Rolling Road Shoot-out.
Surrey Rolling Road, in conjunction with
Pistonheads.com and
Joospeed recently organised a
TVR Cerbera rolling road dyno shoot out, the aim being to find the most powerful Cerbera and also see how good Cerberas really are on an independant rolling road. Many power figures are heard of for the Cerbera, it's widely known that the 4.5 version doesn't make it's quoted power .. now was our chance to find out exactly what the score was.
Joospeed had three cars present, one of which had the latest pre-production inlet mods and had recorded 400.3bhp on the rollers at Noble Motorsport, the people responsible for the engine in the Noble M12 and creators of the 2 litre 350bhp turbo Duratec that is currently causing a sensation. Sadly this Cerbera only made 392bhp on the day but was still the most powerful car tested, and is the highest independantly recorded figure for a non factory normally aspirated 4.5 Cerbera!
Below are the results of the day, kindly supplied by Paddy Richardson.
The names are the sign-ins of the car owners on the
pistonheads.com website forums.
