totally understand where SB is going here
My championship runs similar rules ie a 70% capacity increase for forced induction

I think the capacity I would need from my YB to be in the under 2.0 class would be 1180 lol

Problem with it is I get beat now by class D cars (under 1600CC!!) because engine mods are free so we have saxo's 106 and 205's that weigh about 700 kilos and have over 220 BHP!! my lardy thing (1170 plus driver) had 360 bhp last time out
So I would find myself further down the grid but in with a chance of a class C (under 2 litre ) win.
