The new engine was mapped on the Dyno at Norris Designs & achieved 838bhp/666ft-lb using a GT42/02 Turbo in December 2008 . It will be topped up using Nitrous Oxide to achieve over 900bhp & this will be measured on a future Rolling Road session.  In January 2011 a GTX4202 Turbo was fitted to increase its topend power to an unsubstantiated 860bhp.
