Up, up and away!

Morning all,

In September I'm planning on taking my Wedge on a tour of the French and Italian Alps, however this morning I've had thought: Some of the passes are going to be over 9,000ft and the wedge has the relatively crude flapper system fitted, and is the reduction in atmosphere/oxygen likely to cause the car any problems aside from loss of power? And if so is there anything I can do about it?

Cheers

It could be an issue depending how high up you are..Maybe an oxygen bottle setup for you and the car..Hope this helps..Ziga

I can recommend Timmelsjoch, Passo Giovo and the Grossglockner Hochalpenstrasse... Stelvio of course, but look out for loonies in the tunnels on the Bormio side.

Watch your brakes

Haven't noticed anyone having difficulties with fuelling up there, I'd guess that although the air is thinner the flap AFM still only responds to the amount of air going through it so fuelling should still be correct-ish although absolute power will probably be down.

I took my 350 ( flapper) through the alpine passes in 2009. There was no problem with engine running. I agree with the comment about the brakes. I just had green stuff pads and had no problem, but several of the group I was with,who were in mgb's Tr's & lotus, running standard pads, did have problems.

Hasn't happened to me over during the many times through the Alps (yet) and only once in 200,000 miles....when we were crossing on a mountain back road from North Carolina to Tennessee. (8500ft) These things also are triggered by timing, humidity, wind, ambient temperature. It will start by seeming odd..like the engine is trying harder with less effect. You will find you have to keep revving higher. When you stop, the idle will stumble or simply die.

I got out of the problem by fiddling with the fuel pressure (my cars are fitted with adjustable fuel pressure regulators) and retarded the timing. The watchpoint is how you get down. If you allow the car to coast, BEWARE that the LT77 is very tempermental about that. It does NOT like to be towed or coasted and will take it for a very short time only before causing you grief. If it happens, keep the engine running as best you can as you descend.
