The F2 makes a lot of extra heat that the YSi does not make (poor efficiency at moving the air). The YSi has supported 1200 hp Renegade race cars in that series for many years at that hp level. Mark at Luhn can do either system but at the end of the day the YSi will do the job better at that hp level.
