1996 Ferrari F355 Challenge news, photos and information For the F355, Ferrari developed a new 3.5-liter 90 ° V8 engine develops 375bhp at 8,250 rpm with a redline of 8500 rpm. Maximum torque was 268 pounds-ft at 6,000 rpm. The net result of these 5 remarkable unity of the valve 109bhp per liter.
Aluminum engine block was Nikasil coated wet steel liners. Strange light alloy pistons drove the crankshaft, forged aluminum through titanium alloy rods previously seen only in Formula 1 engines. The biggest innovation is the engine of its five valves per cylinder, three intake and two exhaust, that combined high revs with high intake.
Maximize the efficiency of the gross permeability. The aluminum head was ultra-high strength with variable valve dual-spring stiffness. The radial intake valves conical cam profiles necessary and the high speeds needed a ride to their reliability and longevity. Control lobe central intake valve was slightly offset, reducing pulse pressure and the issuance of a burning hydrocarbons. The valves are actuated by hydraulic valve lifters with automatic play take-up, the first for engines that rev over 8000rpm. In accordance with racing design, Ferrari engineers created an extremely compact high-swirl combustion chamber compression ratio of 11:1. The engine was controlled by a double-injection Bosch Motronic M2.7 filament static electronic ignition, and lubricated with a dry sump oil circuit engine.
The exhaust system was insulated stainless steel and supply of two prominent branch of the catalysts: one main branch of a ceramic matrix catalyst and a by-pass branch of catalysts in the iron matrix. By-pass branch only comes into play at high speed in connection with the opening of a gas valve controlled by the Motronic system. This optimizes engine performance by reducing exhaust back pressure.
