So we've finished the 600/620 hybrid now and we've started to look at ways of improving performance. There are a few things that we can do to help, and one of those is the obvious of removing weight. Last year I was the standard loom but with most stuff stripped off. The 620 engine came with a loom that had all the unneccesary wiring taken off it which saves a couple of lbs. Ducati switched over to using a smaller battery around 2001 so we could make some weight saving by replacing the old YB16AL-A2 battery which weighs 11.5 lbs with the later YT12B-BS battery which weighs 7.5 lbs - that's quite a good saving in weight alone. The rules state it has to be OEM, so before we went and paid Ducati prices for a cheap battery with Ducati written on the side and paid lots of money, Mark headed down to the local Ducati breakers to see if he had any. The breaker did have some, in fact he had seven of them in a pile in the corner. The reason for this is that he gets charged a pound for each battery that he wants disposed of at the local tip, under the European recycling/anti-waste/straight-banana laws or something, so he just stock piles them up. He didn't know the age or condition, or whether they were any good, but Mark could have the lot for a tenner. So Mark takes them all back to his work and sticks them on the deep discharge/charge machine - basically a mofo Optimate - to sort out the batteries and see which ones are any good. Remember that this is the guy who has a workshop full of GT40s, twelve at last count, so they know a thing or two about charging batteries ;-) At the weekend he turns up at mine with a tray of batteries. The machine did the trick, although one was quite troublesome and took a couple of goes, but we now have seven fully working batteries sitting in the garage. Apparently we're setting up a stall at the first race and sell them for £25 a pop!
