Found out what a non-turbo Ecoboost feels like

Cleaned my throttle body this morning. After re-learning, I took it for a test drive. It had get-up and go, but not the kick in the pants kind of get-up and go. Got back and checked it out. Either I didn't tighten the clamp, or I didn't even put the tube on that runs from the inter-cooler to the throttle body. Put it on and tightened it and it's a beast again. What a difference.

    I wonder what's the power output for the 3.5 ecoboost without a turbo? Same for modern diesel engines. I know the old IDI diesels from Ford had 170-185 HP and about 380 ft lbs of torque but they were designed Naturally Aspirated. It's amazing what good turbos do to modern engines.


    Yeh but... yeh but... there is no replacement for displacement, don't you know?

    I always chuckle when I see that posted on these forums. Some folks are so proud of their ignorance they want the whole world to know!

    Back in the good ole days 6.6L diesels put out 100-110 hp and we had power! Moving from the Detroit 238hp to the Cummins 250hp and we had the bull by the tail pulling 80,000lbs. My uncle made his living driving a C series Ford with a 534 CDI GAS engine in his rig. Don't know how many horsepower it was but now I get knocked for having a 5L 360 hp pulling 14500lb gcvw.

    Did the definition of horsepower change or what?
  • This gets my vote for one of the laimest threads ever.

    A loose intake tube clamp = non turbo experience. Get outta here!

    Cracked electrical connector had knocked out the turbos, got it fixed, and it was back to its old self.


    Actually, my guess is that the ECU, upon getting bogus signals from whatever was connected to the cracked connector, simply put the entire system into Limp Home Mode. This has nothing to do with the turbos, other than since very little power was being called for, the turbos never really got going.

    Modern vehicles do that for zillions of different reasons, ranging from bad connectors, to burned out MAF/MAP sensor, to low fuel rail pressure, to clogging fuel filter, among many, many others. I've experienced it in my Jeep on several occasions, not one of which ever had anything to do with the turbo.
  • Two years ago we were towing my fifth to Gulf State Park in Alabama. 60 mi. outside of Mobile, the Eco went into "limp" mode. Took a mile or more to get up to 30 from a stop sign. And there were several on that route....of course, the speed limit had a lot of 65 stretches. Lots of PO'd drivers behind me.

    Drove to the local dealer the next day, and it accelerated like my old Plymouth Reliant. Meaning it would get up to 65 (without the trailer) but it took a really long time.... The good news is my MPG registered almost 40!

  • Add a turner, 3 map, down pipes, new plugs and a 160 thermostat.
    And see/feel a big difference. :)

    1/8th mile 8.5 seconds 80 MPH

    I had the tube blow off my 7.3 while headed down the freeway towing my 40 ft toy hauler. Max speed 45 MPH. Luckily just headed back to the storage yard.
