Thanks for your opinion.
In mine, a rev-counter and temp gauge provides extra info that a mechanically-sympathetic driver can find useful. If you don't care what temperature and RPM your engine's running at, maybe you should buy an electric car, not a Cactus. :)
But I do care if my Cactus overheats, and I would get a warning on the dash if it did. I also care about what RPM my engine is running at, but after 48 years of driving I don't need a gauge to tell me that. I can hear and feel it.

well I don't know what a triple reving at 6400rpm sounds like.
4 cyl at 15000 rpm screeming
6 cyl at 6000rpm grunty
v8 at 6000rpm awesome
3 cyl at 6400rpm no idea, Triumph Triple sounds nice at 11,700 though :lol:

and I had the 110 petrol because I want some get up and go! :twisted:

You don't have to know. But you know if the car you are driving is reving to high.

Rev counter would also allow me to use max torque as I wouldn't be able to feel or hear that. (apart from that gentle shove in the back) :lol:
surely part of the benefit is to effectively use the performance of the engine not necessarily to thrape the nuts off it.
to drive economically its an invaluable aid.
still I've only been driving for 40 years (cars and bikes) and teaching motor mechanics, so what do I know :lol:

If you want to rev your engine no more than 4000 RPM, remember these numbers-

Do not drive over 21 mph in 1st ie 38 kph
Not over 39 mph in 2nd ie 63 kph
Not over 63 mph in 3rd ie 101 kph
4th and 5th ar overdrive ratios.

Calculations are for 110 HP Turbo petrol, manual gearbox, 16 in wheels.

To make it easier to remember- 20-40-60 in mph or 40-60-100 in kph. :D

Bloody hell!!! I'm in 5th gear by the time I reach 39 mph

After reading all the posts about rev counters I'm glad I've got an ETG. :lol:
