Tuning for altitude

Dave Muller · 05-31-2022, 06:58 PM

I'm planning on taking my 382/220 stocker to Bandimere in July. I have typically been running in the 1000 to 3000 foot altitude range, but I expect that going to 5800 feet might require some changes. I will only have two or three qualifying runs so I won't have much time for trial-and-error.

So should I go down one or two jet sizes? Should I add a degree or two of timing? I'd like to start with a good guess before I hit the track for Q1.
