Roush serpentine belt

[MTF]

I'd have to see the belt routing in person, but I assume it provides more belt wrap around the S/C pulley.

There should be a little sticker with the belt routing pasted on the top of the radiator somewhere, if memory serves me correctly.
All that pulley does is ride between the power steering pump to water pump and another pulley that goes up to the alternator.
It does not involve the SC pulley.
I guess Ford may have tried to keep the belt from wiggling in that distance from water pump to power steering. Maybe????
It doesn't route the belt in a different direction it just sits in between.
I have seen other 2014 Whipple setups never saw that pulley being used in that location.
Maybe a Roush thing????? again just guessing.

Your guess is as good as mine lol

See follow up on my post from yesterday.

Between the picture and diagrams, it looks like it reduces wrap around 1 pulley and adds wrap to an idler pulley plus maybe a tiny bit of wrap to water pump.

No it's a common belt.

FORD E-350 2006-2010

Anyone able to confirm if this is the OEM / Motorcraft equivalent of the Roush / FEAD 3200mm belt?

Roush Kit: FEAD 6k - 6K3200-8620

OEM Equivalent = JK61013B / 7C3Z8620N ??

Serpentine Belt - Ford (7C3Z-8620-N) - 2008-2010 F250 Superduty 6.8 +AC​

Definitely not - I couldn't find any 6K 126" belts in the Motorcraft listings either (source Rock Auto parts finder - looked like full catalogue).
