High - flow intake ports were specially designed for the engine, with a cross-section area optimised to improve intake efficiency and increase air intake volume. (motor-prime.com)
As RCR resources quickly became stretched with high intake volumes over the summer, the two cats kept dropping down the rescue wait list as urgent cases like injured cats and nursing moms and kittens displaced them. (reginacatrescue.com)
Efficiency improvements in the engine come partly from a higher expansion ratio, optimized combustion, intake volume control and lower friction. (greencarcongress.com)
