Editing Jaguar AJ-V8 engine (section)

=== Supercharged {{Anchor|AJ26S|AJ27S}} ===

The supercharged version of the [[#AJ26|AJ26]] is used in the high-performance ''R'' versions of Jaguar's cars. The engine was updated with '''AJ27''' specifications for 2000. It produces {{cvt|370|hp|kW PS|0}} and {{cvt|387|lbft|Nm|0}} with the help of an Eaton supercharger (modified Roots-blower). The supercharged engine did not use variable cam timing as the normal benefits of improved volumetric efficiency are not noticeable on a boosted engine.
