Tempest outclasses Typhon at all aspects. Faster, better climb, better turning performance and (often overlooked!) increased rate of roll.
And while no turnfighter for sure, many people do underestimate the Tempest's turning abiltity, most notably P51 and 109K-4 pilots.
Tempest can currently outturn many fighters in this game, especially many of the common E or BnZ types like 190's, Ponies, Thunderbolts and many more.
You are right, torque goes opposite to most planes in game.
Your convergence is much subject to personal preferences. I have them at 350, just like in all of my fighters. The hispanos trajectory and power may enable to shoot at much longer ranges, but if you push convergence range too far out, you might actually miss your targets at point blank ranges because your rounds pass the enemy left & right.
