Say I was travelling along a disused airfield.

Car is completely standard.

In 5th and revs at 4600/4700..

What speed would I be doing..?

Pretty sure its around 30mph per 1k.....

Ok..

Whats the redline on a 500 Hc?

Still had a fair bit in him, pedalwise..

You're not trying hard enough. My shift light is set at 5800 and on the continent lastyear I managed to get it lit in 5th didn't bother looking at speedo as I was otherwise engaged

That would depend on a number of factors determining how quickly the circumference of the driven tyre(s) would rotate along a measured mile to calculate MPH.

Definately something around there.On my old one it used to show a whisker under 90 at 3k revs,though the GPS speed was more like 27mph for each 1k,from memory.I think that there are some with different 5th ratios,and also different diff ratios to others,as well.

I know mine, with LT77,3.31 GKN and 245/45/16 works out at 28MPH/1k

Right..

I remember it being around the 90 lepton mark at 3k so 140ish is right at 4.7k.

I've just had the gearbox rebuilt (T5) hence taking it steady.

Also just had some cooling issues dealt with as could never get the temp to behave. After standing in traffic or spirited driving the temp would rise and then it would start knocking its tits off when under load.

Not anymore... Pulls like a train all through the revs.

Simple answer was to remove the Aircon rad and a re-core to 4 core 1.5 of original rad.
Got to change the lower stat for a normal one now as temp struggling to get above 75. Happy days..

Only took me 4 years but best 200 quid I've spent on him.
