Hey guys
Just wondering if anyone can tell me how much the fuel economy will change if I swap the rear axle on my EF Falcon GLi for an XR6 rear axle? Am I gonna get better acceleration out of this? It just seems the gear timing is letting me down a bit with the 5-speed manual

You will probably use about .5l more per 100km. I still get 8.2l/100km on the freeway in my EL Ghia (now manual), so its not that bad for the extra go.
BTW, 1st with a 3.45 will see you about 60km/h banging the redline. |

I thought the topic was concerning manuals, so I posted as such. |

My mate was telling me that I wouldn't have as good cruising speed coz it would be working on higher revs say when highway or freeway driving. Possibly thinking of six-speed gearbox but would be costly

In an auto, my 100km/h cruising rpm is about 2050.
Going to a manual upped that to about 2150. Not much more, just makes cruising a little more noisier. But fuel economy was unchanged, perhaps a little better. |

Interesting how gearing works, because of the gearing the engine isn't working as hard, so therefore the ECU adds less fuel, even though RPMs are up.
Should also be a smoother ride under cruise control too. Again because the RPMs are already there, a downshift for a hill won't be needed as often.
