I use to race Improved Production but now I just run in the Piarc club sprints these days in the closed racecar up to 2500cc. Its more about beating my best lap times these days. So I expect to better the 1:51 at the Island that was set with my old 1.8 all motor race engine.

Its called Honesty !! Like many sports you have those who cheat and motor racing at club level has plenty of them. To know you have beaten your opponents on a level playing field is more rewarding, those who win knowing they have cheated will burn in hell lol scum bags !!!
