How much power can a Ford F-150 EcoBoost make with a few modifications and a tune? The truck you see here has a 2.7L EcoBoost V6 under the hood, and it recently put down 540 horsepower to the dyno at the 5 Star Tuning shop.
More precisely, the truck put down 540 horsepower @ 5,800 rpm and 550 lb-ft of torque @ 3,850 rpm to the wheels (see the dyno chart below).
This is a crazy amount of power for a small V6. Here is how this truck makes power. It’s packing upgraded turbos, intake, exhaust, and a special fuel blend. The F-150 STX crew cab you see here has a 3.55 rear axle ratio.
The larger turbos are CR Performance Stage 3. The exhaust system combines a SPD down pipe with HI-FLO catalytic converters, SPD mid-pipe with a resonator, and a Magnaflow 3-inch diameter single pipe exhaust. The intercooler is upgraded by Mishimoto, and under the hood is a S&B performance air intake system. This system can flow a lot more air than stock. The fuel is an E30 blend. It’s a blend of 30% ethanol and 70% gasoline.
When the guys at 5 Star ran the same truck with stock turbos, they got 310 horsepower & 379 lb-ft of torque to the wheel. The bigger Stage 3 turbos account for an additional 230 wheel horsepower and about 170 lb-ft of torque.
Naturally, the 5 Star tuning (using HP Tuners) plays a big roll in making it all happen – building the power in a smooth and repeatable manner.
