You have remember though, that’s the cfm listed for the motor only. How much more does the fan blade add (whether it’s 5, 7, 9 bladed) is as subjective as the total number, since there are so many factors that go into it. I’m not sure if the 1300cfm total is from the factory with everything assembled or not. It would make sense to see a number like that, because most big aftermarket fans advertising numbers in the 8k-10k range are only that high because they are listing the “full-flow” numbers - no obstructions whatsoever - however, down here in reality-land we have things like radiators, trans coolers, bumpers, baffles and grilles all playing a role in the amount of airflow being moved.Wow if we are only moving 1300cfm total then a cooling fan upgrade may be one of the best upgrades yet. @Geotrash i nominate you to change your before the Yellowstone trip lol
Nonetheless, if I remember correctly I’m pretty sure the number you want to shoot for on a V8 is closer to 2500 (minimum), so if that’s the case then we are asking for trouble by doing any kind of towing in temps above 75* while running stock fan kits. I’m sure glad you guys brought that topic up…now you’ve got me scratching my damn head again.
