mos 1 Posted September 16, 2007 Hi might be a silly question but i will ask it anyway would using a quaife atb diff have a detrimental effect on fuel economy over using a standard diff? i would a thought it would not make any difference but i'm none too sure thanks mark Share this post Link to post Share on other sites
engine killer 6 Posted September 17, 2007 Hi might be a silly question but i will ask it anyway would using a quaife atb diff have a detrimental effect on fuel economy over using a standard diff? i would a thought it would not make any difference but i'm none too sure thanks mark it is only a differential, it will NOT change any gear or final drive ratio at all. it will require the same rev to do the same speed as before, so should have no fuel consumption issue.

jackherer 543 Posted September 17, 2007 You might end up flooring it more round bends which will use more fuel for sure Share this post Link to post Share on other sites
Hilgie 16 2 Cars Posted September 17, 2007 those complex internals only work when cornering or one wheel loses grip...when on the straights the diffs internals don't move at all. Share this post Link to post Share on other sites
Anthony 1,003 Posted September 17, 2007 i was more thinking from a drag on the trasmission caused by the quaife's more complex workings than it actually changing the gearing etc.. Any additional losses from the Quaife internals would be tiny in comparison with the frictional losses from the tires I would imagine Share this post Link to post Share on other sites
