Project F-150 Ecoboost – Making Serious Power with Garrett’s Powermax Twin Turbo and Intercooler Upgrade

Now the exhaust flange bolt must be removed.  At this point, you can unbolt the turbos from the exhaust manifold.

The turbos can now be lowered out of the truck.

When comparing the stock on the left vs Garrett on the right, you can see that the Garrett turbo has a much larger compressor inducer.  You can also see that the inlets and outlets are in the exact right place to make for an easy installation.

On the turbine side, you can see how the wastegate discharge is angled smoothly into the exhaust flow and the turbine outlet has a smoother shaped diffuser. This improves the overall flow of the wastegate and the turbine

To install the turbo, you just remove the flange from the exhaust side of the stock turbo and bolt it to the new turbo.

The turbos are direct bolt-ons without any modifications needed, but you will need to order a couple of new gaskets. The first two are the turbo gaskets which you can see above.

  1. I’m currently shopping for an Ecoboost F150, the stock intercooler setup just does not makes sense to me. First, with the acres of real estate on the front of an F150, why did they feel the need to put the licence plate right in front of the intercooler opening, covering 80% of it? Second, shutters? really? I mean I understand shutters on a radiator for warm up, but on an intercooler? And I don’t buy the aero benefit… with as much penny pinching as oems do, there’s no way that minuscule aero benefit could justify the price. My money is on the condensation build up Ford suffers with on their turbo cars. But to me thats like using pain killers to deal with a broken bone rather than casting it… I do kinda like the idea of fan on the intercooler tho… prolly helps with low speed high load situations that a truck could see..

      1. With the amazing prevalence of turbochargers on vehicles these days, and every tuning company offering a “stage 1” tune that increases boost pressure and fuel delivery, it makes me wonder how many other platforms fall victim to insane intake temperatures when pushed like this. All of the twin turbo German stuff, the turbo 4pot 2.0 everythings etc.

    1. AJ Hartman built a 3.5EB SN95 with the MT82. I bet it’s a riot!
      I wish the package was a little smaller. It would be a fun swap engine if the bay is wide enough.

      1. And then got boned by dyno procedures… ah, NASA.

        But yeah, again, it seems fun. I wonder if the Link GDI ECU would run one of these well.

  2. Did I miss you testing the new intercooler with the same aftermarket tune you ran on the OE turbo/intercooler setup that increased the temps a bunch? If not, did you and what where the temps?

  3. Jeeezlus, power is waaay too easy these days. 435whp on a Superflow on pump gas through a truck drivetrain wasn’t something you could bolt on without sacrifice (comfort, driveability, etc). Now? No problem, hell, you could even finance the parts! 🙂
