When the British first began acquiring P-39's, P-40's, Mustang Mk.I's, how did the supercharger in the Allison V-1710 in those planes compare to that of the Rolls Royce Merlin used in the Spitfire Hurricane at that time? Were they both single-stage single-speed? If so, did the Merlin s-s/s-s supercharger outperform the Allison s-s/s-s supercharger?
I read over and over how the Allison powered planes were at such a disadvantage due to the single-stage single-speed supercharger, but I'm wondering what the Merlin was using at that time.
If they were both using single-stage single-speed superchargers, then why did the Merlin powered engines perform so much better at high altitude?
