[TuxMan]

Can you guys with a 6 speed box tell me how fast I'm going in top gear at 2000 rpm , 3000rpm and 4000 rpm please , have not got a speedo at the moment . Thanks Tux

[jdearden]

Fast, faster, and scary fast

Haven't you got a GPS or iPhone?

Top is 26.5mph per 1000revs so...

2000rpm = 53mph
3000rpm = 79.5mph
4000rpm = 106mph

But what you should be asking is what are the revs for 30mph (1132) and for 70mph (2641) I think

[F.C.]

This all assumes the rev counter is accurate

Yes, using the inbuilt GPS. Search the store for speedometer. The accelerometers are pretty good fun too - I've got one imaginatively named 'acceleration'.

GPS readings are under on hills usually as the phone apps are 2D. That's my guess

[TuxMan]

Thanks for the suggestion Dom , downloaded " speed box" looks great .

[anotherdom]

Ooh - HUD display on that speed box app! Let us know how you get on.

[TuxMan]

Also depends on the profile of your tyres too.

Must be lazy programmers as it's not hard (err - one more variable) to do it properly!
