Ford Working On Twin-Turbo Godzilla V8: Exclusive

Since its introduction, the Ford 7.3L Godzilla V8 has become a hit among Ford Super Duty buyers. And more recently, the traditional pushrod powerplant became available in crate motor form. We’ve also received a few hints as to the Godzilla’s incredible power potential, which is quite impressive in both naturally aspirated and supercharged forms. And now, The Blue Oval has gone the extra mile and created a twin turbo version of the Godzilla V8, Ford Authority has learned from sources familiar with the automaker’s research and development projects.

According to those sources, the twin turbo Ford Godzilla V8 is being tested in at least two Ford Super Duty models, where it’s a verifiable “monster” – quite a fitting description given the engine’s name.

As of this writing, it’s unclear whether the twin-turbo version of the Ford Godzilla V8 will actually make it to production. However, work is ongoing to test the configuration out in the real world. Though photos of the prototypes are currently not available, Ford Authority can exclusively report that the Super Duty models fitted with the twin-turbo Godzilla engine feature heat shields on each corner of the front end, along with a modified hood treatment.

Currently, the naturally-aspirated Godzilla V8 is offered in the F-Series Super Duty, where it makes a very healthy 430 horsepower at 5,500 RPM and 475 pound-feet of torque at 4,000 RPM. Two lower-output tunes are available in the E-Series cutaway, F-600 as well as the F-650 and F-750 Heavy Trucks.

Blue Oval enthusiasts will undoubtedly drool over the possibilities and capabilities of a twin-turbocharged Godzilla V8. We’ve already seen a couple of naturally-aspirated versions of the motor swapped into older Ford Mustang project cars, with a few more destined for professional drag racing entities, and we can only imagine just how much more powerful the engine will be with a twin-turbo configuration.

In fact, many prefer the idea of an old-fashioned pushrod / Overhead Valve (OHV) engine as opposed to Dual-Overhead-Cam (DOHC) motors like Ford’s 5.0L Coyote V8 thanks to their simplicity and copious amounts of low-end torque. And despite its large displacement, the Godzilla also has rather compact dimensions, particularly when compared to the Coyote, making it easier to swap into a variety of vehicles. Thus, the boosted Godzilla would prove to be an intriguing option for many, should it ever see the light of day.

We’ll report more on this intriguing new project as soon as we have it, so be sure and subscribe to Ford Authority for ongoing Ford news coverage.

    With several plants shut down, employees have extra time to engage in “what ifs”.
    This project won’ t likely see poduction as Ford is throwing all it’s development
    money into electric vehicles. A real shame for ICE lovers.

    1. Alex Luft

      Not all development is going electric. A big chunk, sure, but not all.

      There will be a transitionary period lasting 10-20 years (likely closer to 20) before all new Ford models go full EV. That’s plenty of time to do another generation or two of ICE models.

      1. rmkilc

        Likely a lot longer than 20 years. There is no reason to go full EV as there are plenty of resources to keep producing gasoline and other petroleum products that modern civilization wouldn’t exist without for the foreseeable future.

        1. Alex Luft

          I agree. My comment was more on the worst case scenario basis.

      2. Davo

        Alex, you must consider that the President and his followers are hammer down
        to eliminate ICE vehicles as soon as possibe. And, remember when President
        Trump was trying to slow down the Obama CAFE standards, Ford signed an
        agreement with California’s regulators to keep the Obama standards in place.
        A twin-turbo, 7.3L performance engine is NOT going to help their fleet average
        reach the 50MPG level that the Obama CAFE regulations require by 2026.
        Just in the last several days, comments from Ford have suggested the next
        generation Mustang will be electric. Ford may release this 7.3LTT as a crate motor;
        or, maybe in a HD truck, but not likely in any vehicle subject to CAFE standards.

        1. David Jury

          Cafe requirements don’t apply to trucks. Please get your facts straight before getting all sarcastic about the future of ICE products.

      3. James Jaseck

        Electric EV vehicles are great, but quicker charging times are required to win mass market sales volumes!

  2. Roy Chile’s

    Naturally Aspirated , SuperChargered, or Twin Turbo aka EcoBoost Godzilla 7.3 is shaping up to be a great power plant. It would be a major mistake not to bring this motor to market in the Super Duty and as a crate offering for customers.

  3. Jake

    Did I mention it has dual alternators?

  4. robin glass

    just google search Lancia Delta 1000 hp.
    results you will see this derived from 1,798 cc engine 1.7 liters
    tons of articles
    versus this 7.3 liters engine with 350 hp
    or hellcat 6.2 liter 707 hp
    delta even beats all the Japanese supercharged power plants on hp per cc basis
    i had one 1,798 cc Lancia for a while. unbelievable car. Lancia rules!

    1. Woz in Oz

      Lancia Rules! They sure do……that’s why you see them around ummmm nowhere.

  5. Josh

    Ford has done all they can do with the Jaguar, I mean Coyote V8 engine. It’s limited by bore spacing alone. The vehicle groups with V8s is shrinking, so why not join the pushrod crowd like GM and Chrysler? If you can’t beat em’, join em’. Pushrod engines keep the cost down on large displacement engines, like V8s. Also, and most important of all I’m going to say, a twin turbo Coyote may not easily fit into a Mustang easy with all emissions hardware, but a pushrod engine with twin turbos might. Twin turbo charging is all that is left to replace the 5.2 supercharged in the gt500. What better way to test a twin turbo Godzilla V8, than an F250. People will hear turbos and think its a diesel, and the 7.3 is already fits in an F250. This may be the last Gt500s engine right here, in initial development phase. Also, no one is talking about how the 6.8 is gonna replace the 5.0. No one gets the Mach 1 is the Coyotes swan song. And that V8 Raptor everyone is talking about, will probably get this engine before the gt500, did i mention that? Just my opinionated thoughts…

  6. Jeffrey Miller

    When is the “Cammer” version going to appear? (It only took Ford 90 days to produce the original SOHC 427.)

  7. Net345

    Wait… Wait… Please tell me why Ford is using that name? Even if it’s just a “nickname” any car enthusiast knows that the Godzilla name is already in use for Nissan, specifically the Skyline. I don’t care if you’re a muscle or import fan that’s not what this is about(if it was well let’s be honest many engines with even a 1/3 of the displacement can out perform most of these V8’s) . What the main point is they can come up with something original. Yes some can argue that the name is in reference to the engine not the car itself but that’s sounds like a technicality.

    1. Alex Luft

      Sounds like it’s time to go to school.

      1. Godzilla is an internal name for the 7.3L V8 OHV engine in question. It’s not a publicly-facing name. It’s easier to write out “Godzilla” than “Ford 7.3L V8 OHV engine, hence the reason many refer to the engine by its internal moniker.

      2. The Godzilla name is not and has never been used on any vehicle, Nissan Skyline included. What happened is that someone in the media years ago said that the GT-R is like the Godzilla of cars. Nissan never called the vehicle in question Godzilla, nor condoned the person calling the vehicle that.

      Looks like you’re the one sticking to “technicalities” rather than smelling the roses… or gasoline.

  8. David G Rigli

    Ive gotta be honest here, i have mixed feelings on the use of the name Godzilla. I am a complete automotive enthusiast and i have absolutely no “brand loyalty”……. (admitting that may hurt me only as far as hoping to possibly becoming a part time journalist for this page….maybe even a full time journalist but id rather be honest than worry about who gets butthurt) that being said…there is only one Godzilla. ..the Nissan R32 Skyline GTR, ok maybe two….the R34, but that designation was given to the car itself not the motor, so i guess i can give the blue oval a pass as long as the keep the name attached to just the engine and not make some cringe worthy exclusive trim package carrying the name…though i do want to see such a trim package….just without the label….and there is only one vehicle that needs that package…….ok now hear me out….the Raptor…but built on the F250 platform, now add the twin turbo Godzilla, and now you have the Super Raptor….they probably will never build it but….(in my best Matthew McConaughey impression )”they’d be cooler if the did”

    1. viper_crazy

      Godzilla was a nickname given to the Skyline by the public, not by Nissan, and originally used more so as a metaphor rather than a nickname, but ended up sticking as such. Ford nicknames all their motors (5.0L Coyote, 5.2L Predator, 1.5L Dragon, and so on).

  9. TheMan

    Ford builds this V8 petrol biturbo, tests and informs the media so that a possible market especially in California can be researched. The engine drinks a lot more than a diesel, but CO2 is unimportant in heavy trucks and the political and eco popus.
    That this 7.3 V8 gasoline engine biturbo with 650 PS and probably 1000 Nm torque in a heavy Ford truck makes sense for states like California, because diesel is not wanted due to the nitrogen oxides, although more economical than any gasoline engine. It is also known that gasoline turbo engines are extremely boozy at full throttle.
    Regarding CO2 and California and Ford, it can be said that heavy trucks are not covered by the CO2 reductions. It is also the case in Europe that the extremely high CO2 values in trucks are unimportant and not regulated!
    I think GM will have to follow suit and swap the economical Duratec diesels for V8 petrol biturbo cars in order to be able to sell heavy trucks in California.
    It`s translatet!

  10. Mike

    Sometimes people actually have something interesting to say, but not this time! Ugh…

  11. Erik Ross

    Horsepower and torque seem extremely low. The v6 makes these number. Unless the fuel mileage is like 30 combined? Seems to be wasting time.

    1. viper_crazy

      “The V6 makes these numbers” (assuming your talking about the 3.5L Ecoboost) with the help of two small turbos. If you wanted a true apples-to-apples comparison, either remove the turbos from the V6 or give the 7.3L a couple turbos and then compare. (*Spoiler alert* There won’t be any comparison). You’re comparing a motor that’s literally being forced to make that kind of power versus a motor that makes that kind of power simply from the air flow it creates by itself.

    2. Rusty Beatty

      I personally think a twin turbo 7.3L Godzilla V8 makes sense given Diesel emissions are making diesel engines almost impossible to produce and in a Ford F-250 through F-750 with a 7.3L Godzilla V8 could produce around 750 horsepower at nearly 850 pound feet of torque easily and mated to a 10 speed heavy duty transmission the power plant would be nearly unstoppable in all weather conditions and at any elevation.

  12. DennisC

    Now if I could only buy one in a twin turbo crate motor and recreate a modern 1966 7-litre (aka Galaxie)!

  13. Wade

    Honestly seeing a bunch of nonsense in the comments here. I don’t even care for Fords but this article piqued my interest. And then the comments section… What is going on.

    Nearly every car manufacturer has completely halted research and development on internal combustion engines. I have extreme doubts a twin turbo version of this engine will be developed.

    Do your research. Electric vehicles will be our main form of transportation in the very near future. Ford has an electric F150 releasing soon even and I can guarantee that it makes more than enough torque to tow whatever you need.

    Trying to deny or reject the change is only harmful.

  14. DennisC

    “….very near future”. Really? It’s a nice thought but let me simply make three critical points. First of all, until we can recharge a battery to something like 80% in about 10-15 minutes EV’s will be insignificant in proportion to total vehicles on the road. Second, let us assume you could recharge that fast, then that also assumes you can find a charging station when you need one and hope nobody is ahead of you. Battery technology is still evolving including one that can be recharged in about the same time as it takes to fill your tank, yet we are still a few years away. But we still need the infrastructure which will takes years to build out. And third, where do you plan to get all the NMC (lithium, nickel, manganese, cobalt oxide) to make all the EV batteries to replace all the ICE vehicles. There aren’t enough mines in the world today to even extract enough to get us to 1/4 or 1/3 total vehicle production. And it takes approximately 16 years from locating the minerals, planning, approvals, funding to actual extraction. Oh yes, and then there’s the need to build the plants to actually use the minerals and produce the batteries. Maybe you should do some research. We need to continue to work on EVs but ICE isn’t going anywhere for a while except in the heads of politicians.

    1. Larry Tollison

      The one reply not politically or socially relevant, just plain, straightforward facts. I do have a little something to add. My grandfather told me Eisenhower built the interstates I’m this country during his term, thats a crap-ton of work in a short amount of time! Why does it take the same amount of time to fix a fraction or better yet I know of a bypass brand new in NC that took 10 years that is like 55 miles long?!? Brand new, no traffic or anything to hinder or bog down progress. I’m quite sure of the answer but would like to see what everyone else thinks! Open minds lead to unlimited progress….

  15. John

    Hopefully, they get this to work and get the bugs worked out quickly. The Eco Boost sucked for us. Went to Ram. Ford doesn’t stand behind their motors the way one would think. The Eco boost was good for the first 36000 miles then the issues started until one blew up, the other needed a cam and the other rattled insanely…..hope they do better with this one….

  16. James leone

    Every manufacturer has issues but the idea that they are trying out these combos makes the through interesting got to give it to ford for keeping it going

  17. Mark Schaffer

    1 million Cybertruck reservations.

  18. Lee

    No offensive whirring sounds here. Y’all hear the one that was on the engine dynomometer? That’s what an engine is supposed to sound like. Motors are exhaust fans and heaters. Engines are for vehicles.
    Capiche Farley?

  19. sabasigh

    Ford Perf mentioned something bout a Megazilla crate engine a while back. Wonder what’s up with that or if this is tied to it.

  20. Terry Thomas

    I wish people stop with the Cyber truck has 1 million reservations.
    They don’t have the capacity to produce 1 million trucks. So that number is meaningless.

  21. Richard Bathgate

    Iam very interested in the Ford Godzilla V8. Iam always was a GM owner but disappointed in the v8s offered now. Own a old duramax now interested in getting a Ford But don’t think the 6.2 would handle my 8200 lb. travel trailer don’t like the down shifting you get with V8. If guys are willing I would love to test that Godzilla in my own driveway and see what she can do around Michigan hills.
