That's not what I wrote
. I said the V15a's engine was lacking 45PS (nothing to do with the supercharger) and the actual curve had to be calculated for guaranteed engine output. A different supercharger control would only make a difference between 2200 and 4800m, not down on the deck. The only problems mentioned (except major issue with the engine performance) was lack of manifold exhaust covers and rough finish of the engine cover.

And I agree. The Aa should behave slightly different down low and the EN rating was different, too. That's why I am asking if we really have (or suppose to have) a Aa 601 or A version.
Can you guys put a chart together with exact information (all rated ata settings, rpm, rad setting...) for both DB 601A and DB 601Aa with aproximate guestimated max TAS at the sea level?
