A few words about our tuning approach on the Boss Bird:
Since we don't have the budget to grenade engines, we started rich and accepted that fact that we would have dropped cylinders. Each run has the overall mixture being leaned in baby steps; as well as leaning individual cylinders to get them to run more evenly.
At Norwalk last year, we had all 8 cylinders lit for the first 330', then one cylinder had cooled too much from being too rich, and it dropped. Once we get the cylinder stagger adjusted to eliminate that dropped cylinder, then we can lean the entire engine a bit more to make the real power that this combo is capable of. Our best ET of 6.39 is on 7 cylinders with the overall engine still lazy.
Stay tuned...
