Steven’s 482 Horsepower 2013 F-150 FX4

Thursday, July 9th 2015. | 2013 Ford F-150, Reviews

The 2011 – 2014 Ford F-150 has incredible power potential when equipped with the 3.5 liter EcoBoost V6, these engines can have their ECU tuned and along with a few supporting mods you’ll be producing substantially more power than stock (a tune alone can add roughly 70 horsepower and 110 ft-lb’s of torque). When browsing the f150ecoboost.net messageboard I found a user by the name of Steven who owns a 2013 Ford F-150 Supercrew FX4 and he’s done a tune and more than a few supporting mods and his truck is currently putting out 482 horsepower and 591 ft-lb’s of torque at the rear wheels.

I am sure you all are dying to know how just how he got that much power out of his EcoBoost. Which is why I approached him and he has agreed to let me do an article about his truck, which will be the first of hopefully many trucks we’ll be featuring at fordf150blog.com. Steven made several trips Leading Edge Tuning (LET) in Houston, TX to get new parts installed and to get his tune dialed in. Or should I say dialed up?

By how much was power actually increased?
A stock F-150 EcoBoost has 365 hp and 420 ft-lb’s of torque at the crank (which is how auto manufacturers rate their engines), this translates to about 290 horsepower and 335 ft-lb’s of torque at the rear wheels for an F-150. So when we look at the numbers of 482hp/591tq that is also measured at the rear wheels, that is an increase of ~192 hp and ~256 ft-lb’s of torque. That is an amazing feat! Let’s get into, step-by-step, just how Steven and LET got there.

How was this accomplished?
Several aftermarket modifications were installed on this 2013 Ford F-150, it all starts with a tune from LET, this is what brings it all together, the parts that go into modifying will not work as well, or at all without a tune to dial the engine in to work with the new parts you’ve added to your truck. As I mentioned, this on its own accounts for a very sizable power increase. Steven started with his exhaust system, installing catted downpipes and an electronic cutout for increased turbo response and power (read more about cutouts here). He also upgraded his air intake to a unit from S&B (scroll down for buying options and read here for our review of air intakes available for the 3.5 EcoBoost).

Next up was the fuel system, an upgraded fuel pump was installed to deliver more fuel and this was also necessary for Steven to be able to run ethanol, 30% or E30 to be exact. Along with that a methanol kit was installed, this has both a cooling and octane boosting effect allowing the tune to be adjusted to run more timing and boost, which equals more power, we’ll do an article about running your EcoBoost on ethanol, as well methanol, soon. At this point Steven is at 451 horsepower and 532 ft-lb’s of torque at the rear wheels.

Upgraded Ecoboost Turbo

Steven didn’t stop there though, he headed back to LET to have upgraded turbo’s installed, the stock housings were used with upgraded bearings and a 58mm compressor wheel. This upgrade is good for a dyno run of 489 horsepower and 555 ft-lb’s of torque (+38hp/+23tq). But there’s more! When I approached Steven about this article, he asked me if I could hold off for one more weekend as he’d be installing an upgraded intercooler, he already had an upgraded unit from ATP, but decided to upgrade again to a larger unit from AMR, after that was installed LET did yet another dyno run and it came in at 482 horsepower and a whopping 591 ft-lb’s of torque, as you can see 7 hp was lost, but it’s well worth the gain of 36 ft-lb’s of torque. Check out the video below for a dyno run with the cutouts opened up!

Steven isn’t done yet either. When I asked him if he had any plans for the future he indicated that he’d really like to be able to run E85, rather than just E30, to be able to dial the power up even more! We’ll be sure to write an update once he does.

Any Exterior Mods?
In one word, no. To be more specific, Steven decided to build a sleeper truck (you’ll know what I mean from looking at the pictures). This truck will not give away its capabilities until it leaves some unassuming punk in the dust at a traffic light, or of course if Steven gives away his secret by hitting the switch to his electric cutout (and unlocking more power in the progress). I’ve always admired sleepers, be it a family sedan or a pickup truck, for their ability to completely stun whoever you are lining up against. Steven’s F-150 more than fits the bill, that’s for sure.

A tune from Leading Edge Tuning, this is what brings it all together, the parts that go into modifying will not work as well, or at all without a tune to dial the engine into the new parts you’ve added to your truck. A tune on its own can make a huge power improvement over stock.

Catted Downpipes, these help turbo’s run more efficiently and spool up faster by being less restrictive and therefore causing less back-pressure than the stock pipes. Downpipes are the pipes that connect your turbo to the rest of the exhaust system, they also house catalytic converters (unless you opt for catless downpipes).

Electronic Cutout, this has somewhat the same theory as the downpipes, a cutout will divert exhaust coming out of the downpipe straight out rather than letting it go through the rest of the exhaust system, this further relieves back-pressure allowing the turbo’s to generate even more power, faster (for more details on the benefits of electronic cutouts on an EcoBoost F-150, click here).

Upgraded Fuelpump, these increase the amount of fuel that can be provided and thus raise the power potential that the engine has, this was also necessary to run ethanol in the engine, which we’ll talk about next.

Running E30 Gasoline, E30 means the ethanol content of the fuel is 30%, in stock form the EcoBoost cannot run ethanol, and in a lot of stock applications that it can be run it’s often coupled with a loss of power, but when an engine is properly tuned for the use of ethanol it can actually provide a significant power increase.

Methanol, allows you to make more power, safely. It injects a mixture of water and methanol into the fuel/air mixture of the engine, it has a cooling and octane boosting effect which allows you to adjust engine parameters to increase power (more boost and more timing).

Upgraded Intercooler, the intercooler was upgraded to a unit from ATP and most recently upgraded again to a unit from AMR.
