Rev Burner Newby query

[Jabout]

I'm easing into F1 racing with some on line friends.

The headset for comms & on line chat, obscures the engine sounds and makes my poor gear changing even worse.

So I'm thinking of a Rev Burner with a tachometer.

However, F1 cars rev up to 18,000 rpm - the question is, are there tachometers that go up that far?

Or are there work arounds like calibrating 18,000rpm to 9,000rpm on the tachometer?

Thanks for any responses.

I didn't find 18.000 rpm rev counters (I checked Ebay) but maybe other people know other online shops to check.
