I found the dyno sheet of my brothers black edition GT, this was a little unusual though
The guys at herrod put the gt on the rollers and she pulled 338kw at the wheels on the first run, then backed it up with a second and a third. They then concluded that the dyno was out of whack, so they supposedly spent 2 hours recalibrating the unit before putting the GT black back on the rollers only to find it pulled 338rwkw again...
This left them scratching their heads.
They then realised they had another standard 335 GT in the shop, so they put it on the rollers and found it put out the normalish 277rwkw...
At this point they called up my brother and asked him what sort of modifications he had done to the car? he replied honestly "none, you are the first guys to play with her"
This left them scratching their heads some more, before asking him how he has been driving it? again he honestly replied "like I stole it..."
This made the herrod guys audibly chuckle over the phone.
The above results are quite self explanatory, and very impressive for a drop off in the morning, pick up in the afternoon, standard intake, standard exhaust, no internals scenario, and an absolute animal to drive
