BS, do your research
LOL Are you for real?
Heck engine masters did an episode on this and proved it.
It does diverge. So the more rpm, the less it likes it. Boy, wait 'til we put that fixed fan on there. That's going to be a lot worse. So clutch fan, minus 7 pound feet, minus 14 horsepower.
This is with a PLASTIC flex fan... let alone the metal one that will eat more power....
(Air drill whirs) did you take the belt? Okay, plastic flex fan, ready to rip. Okay, plastic flex fan. I'm almost wondering if it's going to be better than the clutch. Never know.
(Exciting music) (engine revs) whoa, that's hideous! That thing's junk! (Laughs) it's so horrible! We just made 388.3 pound feet at 3800 and the horsepower 325.1 at 5100. That is pathetic. We just lost 18.6 pound feet of torque.
Looking at the horsepower number, we just lost 23.9 horsepower
, from no fan to plastic flex fan. You know, when you said 30, I thought you were maybe crazy-- - no! But I think-- - i've seen this.
Then a fix aluminum fan:
Next up, we've got our fixed aluminum fan. I thought I was ordering a flex fan, but it's actually not. And I think there's a good chance this makes more power than the plastic one, 'cause it doesn't have as much pitch in the blade.
I think you're right. We'll find out. I'll go with that. (Exciting music) (engine revs) it's better than the plastic one, but it's still killing power. - yeah. It's not much better, is it? Yeah, it goes five or six horsepower better.
Look at the overlay. So we just found out that that aluminum fan versus no fan at all kills 12 pound feet and 20.3
horsepower, so not as bad as the plastic one, as you can see here on this curve.
