Im not hating on the new motors because i really like the line up, but i wonder what a 5.4 with a 10.5:1 compression could do.

At 6 psi the Mustang GT made 543whp and 521ft-pd of torque at the wheels.

Edit : And the Ecoboost have 10:1 of compression. Not that much less then the 5.0 in the F150... I guess we won't see alot of boost out of the Ecoboost then hahaha

Why would the 5.0 grenade with boost at 10.5:1 but the ecoboost will take much more boost at 10:1...


Ford said the 5.0 was built to had boost later... I sure ain't scared to put boost on the 5.0. SC and 8 psi will give over 500hp and 500ft-pd of torque with a beautiful V8 sound


If Honda can take boost and stay reliable with 11:1 or 11.2:1 (S2000) of compression... I sure hope Ford can take it to with 10.5:1 :o

The F-150’s 5.0 benefits from some of the work done on the Mustang’s 5.0, which was engineered with the goal of being able to add a supercharger at a later date to boost performance, Harrison said.

“We put a forged crank and good rods in [the Mustang’s 412 hp, 390 pounds-feet 5.0 V-8],” Harrison said. “The head bolts are upsized. The main bearing bolts are upsized. That then lends itself for a very robust truck application.”

The 5.0 also uses Ti-VCT to continually optimize power and fuel economy during two cam timing schedules – one for performance and one for mileage. It’s also E85 ethanol capable, which gives it increased power figures (and lower fuel economy), though Ford won’t say by how much.

There are some physical changes, too. The exhaust headers for both engines are different from each other for extra durability in the F-150. Instead of the Mustang’s unique tubular stainless-steel exhaust headers, the F-150 uses thermally tougher conventional cast-iron exhaust manifolds that give it a small loss in low-speed torque and performance, which has to recovered to improve the driving experience and meet long-duration high temperature work demands – such as during cross-country towing. To do that, Harrison’s team shrank the duration of the intake cam duration from 260 degrees to 240 degrees, dropped the compression ratio from 11:1 to 10.5:1 and advanced spark timing for extra low-speed torque. The changes also help F-150 owners run their 5.0 V-8 with regular unleaded instead of super unleaded for optimal performance in the Mustang.

The F-150 5.0 also gets a heavy-duty oil cooler that's not shared with the Mustang.
