Following a visit to Gerald Dale Motorsport for a rolling road session, Grammy’s power has been significantly increased. The first run showed 135bhp and 122.1 lb ft of torque. After a bit of fettling, these figures were increased to 180bhp and 152.4 lb ft of torque. Just goes to prove how valuable a rolling road session is to set up a car to obtain the best performance.

Unfortunately the water injection was not working and so the boost was limited to 14psi. The pump has now been fixed and another rolling road session is planned to try and increase the boost to 20psi. Watch this space for the results.
