That works, and allows the shroud to be closer when horizontal=less width=less to cut off output shaft and fit under stock hood. Look for lower amp h.duty, h.o.(6-7") fans, and small(light) moto 12v batt is all u need.Add a 2pole quick disconnect and custom jumper cables to recharge if running multiple classes and short on time between races. As far as fan is concerned, no fan is as good as it gets when reclaiming lost hp, just make sure the cooling system u run will last duration of longest race u run ( some h.o. electric fans will kill a small battery quick) smaller the battery-less weight, match the parts as needed.Don't cut on till u need it; up to running temp - hmm.. then u might be able to run a lighter battery.
