Not Ranked
Automan,
What you're seeing is exactly why I swapped my 3.54 gears for 3.0 gears last year. I have a Richmond 5 speed with a 1:1 5th gear and I was turning high rpm's at normal hiway speeds (75 - 85) and burning beaucoup gas.
I haven't checked my mileage this year but the rpm's have dropped to around 3,000 avg at those speeds. Feels much better and not like I'm ringing it's neck on the freeway. I also get to use first gear. The Doug Nash has 3.27, 2.13, 1.57, 1.24, and 1:1 gear ratios I think. That first gear 3.27 winds it up pretty quick with a 3.55 rear ratio. Much better with 3.0 rear.
