These nitrided austenitic steel sleeves were the result of many years of intensive sleeve development, experience that Napier did not have.
This in turn would cause sleeve seizure and/or loss of compression.
Testing with Taurus sleeve material, tools and manufacturing techniques was a overhelming success.
So give a hail and cheer the greatest fighter of the war. The Tempest became the principal destroyer of the V-1 flying bomb (Fieseler Fi 103), since it was the fastest of all the Allied fighters at low levels.
