10,000 plus feet, or so, driving my Healey, is something, living in
Sydney, NSW, Australia, that I've never previously considered.
I think if you have SU's, on a road car, just cruising around, you can
back off a flat or 2 or 3
Or not. Your car.
Have fun.
However, for all those who say altitude makes no difference, consider
this.
Mt Panorama, Bathurst is about 780 metres above sea level. Wakefield
Park, Goulburn is around 700 metres above sea level. (yes, you other
Aussies, guess what! Weber jetting is the same for Bathurst as for
Wakefield)
So with Webers, you either go one size larger on the airs, or one size
lower on the mains. Your choice
And that's at 700m (2,300 or so feet above sea level)
Your mileage, horsepower, attitude and fun may vary.
Geez. 10,000 feet. That's awesome.
I could tell you the story of boiling my Bugeye sprite at 2.00 am,
with snow on the ground, with no soft top, on my way from Jindabyne
back to Thredbo - but I had SU's. And back then, I had no idea of the
whole altitude issue.
And......
