Right well little update, Doris is having a little make over, pod didn't go well atall, think that my maths haven't worked, basically she can't build enough boost before it reaches the end of the rev range, so, going to remove the Spacer Plate but set the timming up a bit better (retarded) now I've got a vernier pulley and a few other toys, looking for a cheep mega squirt, oh and I've got a garage full of parts I'll be fitting over the winter, carbon rear diffuser, carbon back box, New drivers seat, racing mirrors, wide arch kit and some other toys, so hopefully next year she should be looking pretty frikin mental :-)
