Christmas time

Yves,
3.58 / 4.08 = 0.877 is the factor that you multiply your old rpm with to get your new rpm after the swap.
So if you ran 5000rpm before, you will run 4387rpm now.
So 1200 - 1300 rpm drop sounds a bit optimistic to me.

Yes Ulix, my reading of the tachometer was wrong, possibly too enthusiastic ... I'm going to need glasses. The numbers do not lie, thanks to Brad and Kmead.
But one thing is sure, the driving pleasure on the highway is undeniable and I do not regret.
