Turbo Upgrades for the ecoboost?

That said, the 600+ lb/ft engine torque probably helps get that big truck to that 100+ mph trap. I just don't see 500 hp there with those tiny turbos.

According to Full Race, the stock F150 EB turbo's are good for a combined 47 lb/min at choke. That should be good for 500 hp.
And just FYI, I used the basic hp calculation using weight and mph. Keep in mind that the conditions were very good when the 103 mph pass was made.

If what FR is saying about 47 lb/min at choke is right, then 470 hp would be a conservative estimate. A rule of thumb is actually that 1 lb/min = 10 rwhp, but that generally applies to manual transmission cars with less drivetrain losses.

Not very easy. You need to be able to hold it at a constant, known shaft speed and measure flow rate, inlet temp, discharge temp, inlet pressure, and discharge pressure. The most difficult part on these would be holding it at a constant, known speed, as they likely spin well over 100,000 rpm.
