Thanks for that. :y:
I was thinking of it because the 5th Gear is suppose to help with Fuel Consumption on Highway-Driving, but it's only an 800rpm difference to a 4-speed. And to make 5th Gear like every other gear, it would improve the economy even more.
By having a dragged out 5-speed, it would mean you still get the same Ratio of 1st to 4th, and a 5th that would be a cruiser gear, driving at 100km/h revving at @ 2500-2800rpm.
I know with a 4.5 ratio diff (tested again on Forza 3 -- Redline @ 6000rpm), 1st goes to 40km/h, 2nd = 65km/h, 3rd = 100km/h, 4th = 140km/h, and 5th = 160km/h. But at 100km/h, 4th is revving at 4000-4200rpm, and 5th is revving at 3200rpm.
Behind a 4K "Hi-Cam", I know is not the best engine for all this, but it does have Extractors into a 2" system, and it will have a either Jetted 4K Carby, or a 28/32 Weber on it.
We live behind the Melbourne Airport, and to Travel to, for example, Church on a Sunday (Glenroy), More than 70-80% of the Drive is 100km/h zones. So it could be under the definition of Country Driving. (Lancefield Rd = 100km/h, Sunbury Rd (and through Bulla) = 60 and 100km/h, Tullamarine FWY = 80 and 100km/h, Western Ring Road = 80 and 100km/h, and Pascoe Vale Road = 60km/h).
And having said that, a longer 5th Gear will be great for Fuel Economy, and for cruising. :)
