Roofbox Question

[matt1e]

OK Yes on the roof is the obvoius answer.........

 

BUT.....Is it more efficient to have it forwards on the rails - where it breaks the airstream itself in cleanish air and that air flowing up the bonnet and windscreen hits the underside of the box and goes below.

 

OR

 

Mount it further back - so the air flows up over the bonnet and windscreen and hopefully the trajectory (?) of the air carries on over the roofbox !

 

I am asking as I can't remember which made the biggest difference on my last trip to Italy.

 

Ideas and knowledge please, and it is a wide 750ltr box with a low front.

 

Cheers,

Matt

Mounting further back would be the logical move as far as streamlining is concerned.

I always mount mine further back for streamlining - handles better too as it doesn't try to take off!

...Managed 45.6 mpg Blackpool to Folkestone at 70mph (cruise ctrl).

 

Mounted it far back......cheers !
