Wikid thanks for the info peeps, and yeah the scooby is poor on fuel and just about everything, I also had an rx7 which was worse, one of my mates has a ph2 172 cup and he just has it as a track toy but I cannot afford to do this just yet do I want to sell my scooby and buy a ph1 172 to use as a daily runner to also let loose on the track. Again cheers guys
