It did feel noticably better, and not much was pulling away from it down the back straight including some the big 1000s, it had the legs to pull past Jon on his 748 down that little straight . I am not sure if the slightly newer style RS pistons have had any effect?

I am quite interested to get it on the dyno again, maybe when I get the 300 set up over winter I will take it for a quick power run and see where it is at now.
