Another thread from the dead, but this one is still twitching. Does anyone know what the cfm is for the stock VFR fan? I'm looking at a Spal fan, which is 311cfm/530 m3/hr (for the rest of the planet) and it's thin and lightweight, plus, it pushes, not pulls. I'm wondering if that may help increase airflow over the stock fan. They also make fans that pull. I'm also looking at a larger oil cooler from the RC51.
