I note the new Jaguar F type R has a 5.0 supercharged V8 producing 404kw.

Magically that is what FPV claim from their 5.0 supercharged V8. Almost identical

Does anyone know technically how close these engines are?

I note no one has any issue with Jaguar quoting 404kw form a blown 5.0. However when FPV did it the world stopped and it was scrutinised to within an inch of its life.

I'd be interested to hear from anyone who knows the tech specs and can expalin the similarities or disparities of these two engines.
