I got a shock on Saturday night with the times I got. I put a BPT cold air kit on the Boss mostly as an experiment. I got the kit second hand and put it on and since then the car has only gone better and the fuel economy has gone from max of 350 K a tank around town to a minimum of 400. This is the only mod I have done to the car. My trusty Melways has been with me on every run that car has made so I don't bother lightening the thing by taking out the spare or stuff like that.
here is a link to the two 13.6 time slips :Timeslip Pics
It goes to show that the BA isn't the slug it's made out to be. I may have a better than average car and the track was damned grippy for me but the runs are on the board ( so to speak ) and cannot be denied.
I don't think I will bother trying to beat that as it is my everyday car and I don't want to break it but a 13.5 is soooooooo close !!
Ford could do worse than to do this sort of thing to increase the BA's power and fuel economy with no great cost. What a damned fine car the BA XR8 is.
