Circle Performance, www.circleperformance.com in Massachusetts has posted dyno test results conducted in June. A Ford Ranger version Duratec 2.3 fitted with mechanical fuel injection, belt-drive higher lift cams, a dry sump oil system, forged high compression pistons (14 1/2 to 1), forged rods, a steel crankshaft and burning pure methanol alcohol is making about 320 peak h.p. at 7500 rpm.
At 6100 rpm the engine makes about 280 h.p at 240 ft/lbs torque. This engine is naturally aspirated...no boost!!
I understand that Circle has not performed any headwork. No porting and polish and still using stock valves and springs. Their engines are for sale.
