Lambda = 1 operation up to an engine speed approaching 5000 rpm is possible, with only moderate enrichment necessary above this with a turbine inlet temperature limit of 980 °C. (greencarcongress.com)
Lowers air inlet temperatures, which reduces turbo outlet temperatures in turn increasing torque output (performanceparts.ford.com)
A water - cooled, integrated exhaust manifold helps reduce turbo inlet temperatures while providing increased engine reliability. (greencarcongress.com)
