Hello all, i would like to know the engine HP for the Spitfire Mk Vb and the Mk IXe.
A guy and i cant agree he says that the Mk Vb only had 1208HP and i said that i had 1470HP... witch i'm pretty sure that it had.


So please help me out here guys!
 
I got a source here that list the Vb as 1,585 hp and the Vc as 1,470 hp. The cause of the confusion could be do to altitude or which stage the Merlin's blower was in. Both of those would affect hp.
 
You sure that the Mk Vb with the 1585HP wasen't the LF one because they had a stronger engine?

And i'm not looking for the HP when they had boost on, just when they flew normal... not panic HP.
 
Hope this helps:

The Spitfire Mk Vb used a Merlin 45 or 46 engine also 50 and 55 (same as 45)

Merlin 45
Take-off 1,185hp at 3,000rpm
International rating 1,200hp at 2,850rpm at 16,000ft
Max power 1,470hp at 3,000rpm at 9,250ft

Merlin 46
Take-off 1,100hp at 3,000rpm
International rating 1,115hp at 2,850rpm at 19,000ft
Max power 1,415hp at 3,000rpm at 14,000ft

I got a source here that list the Vb as 1,585 hp and the Vc as 1,470 hp. The cause of the confusion could be do to altitude or which stage the Merlin's blower was in. Both of those would affect hp.

The 1,585hp is for the L.F. version engine the Merlin 45M
