Porsche RS Spyder Engine, Revised with Direct Injection
While it’s normal for most automakers to take the lessons learned from motorsports and apply them to their road cars, Porsche is doing it the other way around.
The 3.4-liter V8 in the Porsche RS Spyder campaigning in the ALMS LMP2 class will be fitted with direct injection, bringing power levels up while reducing fuel consumption. While the old mill put out 476 hp at 10,000 RPM and 273 lb.-ft. of torque beginning at 7,500 RPM, the new engine gets a 27 hp bump, to bring levels up to 503 hp at 10k RPM and 284 lb.-ft. of twist at 8,500 rpm. Fuel consumption is also down.
