Ok I'm somewhat of a numbers geek and I can't find this info on Ford's site or google. How much boost PSI does the Ecoboost make? Also just out of curiosity, what is the amp rating on the factory alt. on these engines? My Edge was 150amp but can't find any rating on the truck. Thanks very much in advance if anyone knows.

 

Im not 100% so dont quote me but I think it peaks about 15psi around 3grand goes down to about 12 before it shifts.

 

Wow that's a lot more boost than I expected. I figured 8-10 pounds was more like it. This little motor is wound tight lol! Thanks for the info

 

Id say the motor is build well with plenty to go. I bet it can take more boost without thinking twice about it.

Its got 6 bolt mains for crying out loud.

 

The maximum boost is 12 psi and the the alternator produces 220 amps.

 

That's what I was looking for...thanks!!! Wow that alternator is stout!! lol Must need it to power all the gadgets!

 

right 12psi.....unless..you tune it (MPT puts mine around 18psi, now just need to get that boost gauge installed...if I only had a Pod)

I see everyones boost guage at 16 psi and thats what I read. (atleast for the 2011 F150) The SHO and Flex is 10 psi. Our trucks drop down to 10-12 psi before it shifts to save the tranny.

 

It can, performance tunes on some run 18psi

 

I have seen the boost on an Edge CS hit 17 on level 3.
