Actually, I have to agree with Don here.
Take a look at
http://www.powerstream.com/Wire_Size.htm - The rated currents for Chassis (unbundled) and Power Transmission (bundled) differ by about a factor of two.
Tight wire bundles can have an effect. I usually tell students to put it on the "nice to have but don't panic about it" priority level. I just don't recommend that teams put their entire power flow through those wire guides.
