Interesting indeed.

It says the Merlin was not as "smooth" as the Allison.

It indicates that German aeronautical research contributed to it's design (which we already knew since the designer left BFW and defected to the US after having worked on the 109). But it's nice to hear because it is a knife in the argument that the LW planes had crapy aerodynamics.

But here's what gets me - "The shift from first to second speed in the first stage of the supercharger was barely noticeably, a mild kick at about 8,000 ft., sort of like downshifting your car from 4th to 3rd at 30 mph."

Downshifting my car from 4th to 3rd at 30mph is not a "small kick" by any stretch of the imagination. More like a snap to the neck, assuming the tires manage to bite. /i/smilies/16x16_smiley-very-happy.gif

Yoikes!

Funny, because it made sense to me- as long as I bring the clutch up carefully, all I notice is the rise in engine RPM's...........

"As weaponry, both were good, but in far different ways from each other. In a nutshell, I describe it this way: if the FW 190 was a sabre, the 109 was a florett, or foil, like that used in the precision art of fencing." - Gunther Rall

Well, I'm assuming that the point is to get more power, as that's what the purpose of engaging the next sc stage is for after all. /i/smilies/16x16_smiley-wink.gif

That shift would take me up over 2000 (maybe about 2500 - I'll have to look more carefully) and put me right into the range where the power starts to really come on. /i/smilies/16x16_smiley-happy.gif

Thats sounds about right in tune with what I've read from some WWII pilots. But in contrast some Pilots loved that plane like it was their first wife.

Interesting how the P51 and 38 compared to German and Japanese aircraft.

P-51 did better in the ETO.

P-38 did better in the PTO.
