jonny-rotten - Interesting thread. All info from flitecontrol is right on the money. I was thinking in your original post that you meant you shift it when the "engine" says to. Not the speed marks. I first read flitecontrol's reply and was like, "what?" Then I looked back at your post. If we have an all Rebel drag race (I guess that's not going to happen due to the virus, and the lack of participation), then using those lines on the speedo would be beneficial.
When I'm just cruising around, I shift when it feels / sounds right. There's some sort of engine speed that I just sort of feel a bit of buzziness. Very subtle. I shift there and the engine picks right up at the lower rpm with good torque. Not racing torque, but just comfortable acceleration torque.
I'm about to do the Zombie Apocalypse Challenge. And when I do, I'm going to have to achieve 102+mpg, or I get eaten by zombies. I got a feeling there's a horde of zombies out there that's gonna turn me into a buffet.
