I recently read an article (more than one in fact) about the new 2011 Mustang 5.0 having been dynoed and it was found to have 397 HP at the rear wheels which would typically equate to approximately 440 - 448 hp at the crank when you take into consideration the industry standard 11-13% drive train losses. Now Ford rates the engine at 412HP and many are saying that they underrated the power (for many reasons) and I was wondering if that same tactic might have been applied to the 3.5 Ecoboost. Has anyone seen dyno specs of a production factory standard SHO they could share? Not being up on all the details but I seem to recall a very ambiguous statement being made during the introduction of the Police interceptor about the output being "in excess of 365hp"which at the time struck me as a funny statement since typically they provide a specific rating. Now I’m thinking that maybe they have also underrated the 3.5 and could add another 10 hp or so as they deem it necessary. I would be interested to hear others opinion on this subject especially if you have data to provide.
