    • 2017 Ford F150 Raptor 3.5 Ecoboost HO (High Output) has 450 horsepower and 510 lb-ft of torque

      It looks like the engine specs for the 3.5 liter High Output Ecoboost V6 under the hood of the 2017 F150 Raptor have finally leaked. The motor was stated to have at least 450 horsepower by Ford and that is exactly what it has.


      Torque is an impressive 510 lb-ft. In other words, 76 lb-ft more than the 6.2 liter naturally aspirated V8 it replaces. Not bad for a motor almost half the size.

      Other aspects to note are the dual port and fuel injection system which should make power upgrades a breeze and the forged crankshaft.

      The new Raptor is going to be a beast.

        I have a few friends that have the 3.5 EcoBoost engine in their trucks and it gets mixed reviews. On paper it looks like a monster, but it struggles on the road. Hook a trailer to the truck and it really suffers. One guy actually took the truck back after a week and traded it for a V8.

        This is an updated 3.5 though and they have a new 10-speed trans.

        Hmm that's very odd. My father has a XLT Ecoboost that has 200,000 miles and counting, and struggling wouldn't be the word I'd use. He pulls his camper all over this country, and he pulled my DD beater Audi S4 from Tennessee to Ohio for me with absolutely zero struggle. Again his truck is literally bone stock.

        It isn't really designed as a towing engine though. Even for a gasoline one. If you are towing anything that is heavy enough to be noticeable you shouldn't have bought a raptor. That is why they sell diesels. This engine is supposed to be high performance for the truck.

        That said. I use a N/A V6 Grand Cherokee to tow a 2000 lb trailer with a 4000 lb ish CJ-7 on it and don't have much issue. So I think this motor will do fine for the occasional load. You just can't expect it to perform like towing rig.

        Didn't the Ecoboost V6 have a higher tow rating than the naturally aspirated V8?

        The Raptor is rated for 7000 pounds and it isn't even designed to tow.

        Hmm - C&D did this exact comparison and the EcoBoost dominated everything other than fuel economy, including pulling a 6,400lb trailer.

        And this is before the updates and 10-speed for 2017.

        Turbos like load. I see no reason why the Ecoboost would not make a good tow rig. The torque helps rather than hurts.

        None of the raptor engines have been designed for towing. Gas isn't great for it, I would think that of them the ecoboost would be best though.

        Because it would get $#@!ty gas mileage while towing a heavy load compared to diesels, no one buys gas for a dedicated tow rig. Just having the power to pull isn't the only factor.

        But the other big factor is what the suspension is set up for I doubt the off road suspension is set up the same.

        I agree that for what most people tow is should be fine though.

        My point is if the Raptor can tow 7000 the F150 Ecoboost can tow even more.

        Gotcha.

        Suspension is the main factor for tow rating though.

        The suspension is up to tow for sure. Maybe not over 7000 but who really hauls that much on a recreational basis ya know?
        That's what 2500 and up is for. And don't discount gasoline engines either, many box trucks pull serious weights with big block gas engines. Is it as efficient? No, but they certainly are capable. Diesel is absolutely where it's at for big towing, but they all have drawbacks. For one every new diesel is strapped with DEF and DPF systems and don't even get me started on those.

        The Raptor could do all the towing I would ever need.

        A small motor boat, PWC's, my car, etc.

        Exactly, most people do not tow big weights, if you do you know who you are and you know what you need.
