I've got to repair my HX transmission and I have been thinking about just swapping it for a VX instead of repairing. Right now I am at 2250 RPM at 60 mph. I have slightly taller tires than stock.

I'm around 1950rpms at 60mph. The '93 CX transmission is without doubt a big factor, but I follow the idea of getting a bunch of small benefits from multiple mods--weight, engine, and aero--together and "stack" them up until it equals a big difference. The biggest benefits seemed to come from deleting the power steering and the alternator. Deleting 200+ pounds in weight from the car. Pumped up tires. And the airdam and grill blocking. I think the WAI helps too--or at least my testing suggested it did.
I did very little hypermiling, by my standards, on this trip. So the engine kill switch was less significant than usually. I held steady throttle as much as traffic or hills permitted. At some stretched the instant MPG reading would cross 70. At others it would be under 60. I did some mild drafting, one or twice cut the engine, coasted in neutral down the rare large hills or when traffic piled up in front of me.
Warm weather helps a lot. I won't get this number in the winter.
Need more aeromods!
