11:1 and even higher on the focus enignes....I only wish we could run unrestricted....might have a chance against a 6R4 latest grp'a' cars with a T34 runs about 310 with approx 600 lbs/ft of torque....2.5 bar of boost....there is alot to consider in the specs when you look at grp'a' rally engines, wrc engines and good track car engines.....they are massively different....
