It was about 12.5:1 but was too high. You can hear little self detonation in low rpm. Got problems with head gasket. I change ratio 11:1 it was much better then :)

I'm also working in a B20 engine, from a Volvo Amazon 1969 that i'm preparing for Regularity Historic Rally. What camshaft do you installed? For me would be enough 150hp. Thank you.

@jlredo If you want just 150 hp you just need to do more bigger outtake holes from upperdeck and maybe bigger valves and harder camshaft. In my first assembly, i got original doupple SU carbs, original valves (44/35) and modified intake/outtake holes and 300/11,9mm camshaft and good exthaust manifold. =150 hp. (46/38) valves and 45 doubblecarbs and harder cam (320/12,5mm) you can get 180-200 hp

Modified sylinderhead, bigger valves, douple valvesprings, intake manifold, exhaust manifold, lighten flywheel, rally camshaft, electronic ignition, electronic fuelpump, 2,5'' exhaust. This is historic rallycar, still 2000cc engine, rally gearbox, diff lock rear and so :)
