This may sound like a stupid question but not having driven a mini with a rev counter in it, what sort of RPM should I be looking at to change gear.

I am building myself a digital rev counter as part of a college project and want to add a 'shift light'

Thanks,

Seb

When i'm driving normally I change about 3000rpm (except first gear, which is about 2000rpm (3.44 FD)) but when I'm really wanting to move I normally change about 4000rpm.

Normal up-shift at 3000 to 4000 rpm. Change up at 6000 rpm when in a hurry as max power is at around 5500 rpm with a standard cam.
It is worth noting that the original 998 Cooper would cruise all day at 80 mph (no speed limit on the open roads then) and that was about 5400 rpm.

Depends on lots of things. I typically change around 4k, but hold on for 7k when motoring. As it's a project I'd think a two stage light would be good. Green light for economy change (say 3.5 to 4k) and a light somewhere near your rev limit.

3-4k sometimes more if I want to give it some revs. 998's love to revved.

You could also add a rev limiter if it'd help you score brownie points, go a step further and have it switched by the gear lever so you can do full throttle gear changes.

Thank you all for your input. I have decided to use wills idea

Green light for economy change (say 3.5 to 4k) and a light somewhere near your rev limit.

and I will decide on a point at which the light changes with your suggestions

Thanks,

Seb

Optimum for the red light is approx 500rpm more than your peak power RPM, which depends on the engine you've got,

I change at 3500 unless i'm feeling sporty
