Im thinking 447 bhp should be possible CAI/Tune without the constraints of SMS Manufacturer of Record Full Emissions Testing and Durability Warranty. That allows us to go to a freer flowing CAI without a carbon trap and more Agreessive Tune.
The engine actually starts out at 406/381 according to the actual certification test on 91 RON (87 AKI Pump). Why I chose the Regular Gas number instead of the Premium will become clear.
Factory Air Intake flows 800 cfm (2011 5.0L) vs 550 cfm (2005 4.6L 3V).
800/406 = 1.970 cfm per bhp
550/303 = 1.815 cfm per bhp
My experience has been it takes around a 50% Gain in Airflow to get the majority of the gains in a 2005-2009.
You can gain around 20 bhp from a CAI and 10 bhp from a Tune on a 2005-2009. Many will disagree but I picked up 0.4 and 3.5 mph. I trust the track more than I trust the dyno.
So thats rougly 3.3% Tune and 6.7% CAI.
A 5.0 should pick up roughly 3.3% Tune and 5.4% CAI (Given factory flow and a 1200 cfm aftermarket unit).
406 x 1.087 = 441.3 bhp.
Im unsure how much exactly you would gain with the pulleys considering how much more efficient the 5.0 Waterpump is and the Electric Power Steering Pump. Personally Im not a believer in the Electric Power Steering as a Dragstrip aid as my own experiments have shown little to know change in ET and Trap Speed when bypassing the 2005+ hydraulic pump as Im not a "Wheel Sawer" however many claim they saw gains.
Around 2-2.5% for pulleys is typical on a 4.6L 3V. I believe most of that is from waterpump drive savings. Given the pump is way more efficient on a 5.0 you might get 1.5%.
441.3 bhp x 1.015% = 447.9 bhp
Longtubes are good for 15 bhp according to the Lead Powertrain Project Engineer.
PS Thats it for todays class in Mental Masturbation.
