FutureStarrFirst Fire Up of Our Twin Turbo 7.3L Godzilla Engine!
The 7.3L Godzilla engine produces 430 horsepower and 475 pound-feet of torque. Additionally, it has a flexfuel option that lets it run on gasoline as well as E85 ethanol blends.
Ford commercial truck market will surely welcome this addition to their E-Series lineup, but what capabilities is it really capable of without some serious aftermarket tuning?
Have you ever watched a dyno run to witness how much power an engine makes? In this case, the 7.3L Godzilla pushrod V8 produced an impressive 430 horsepower and 475 pound-feet of torque at just 6,000 revs!
Ford's Godzilla engine is their first major non-hybrid or EcoBoost development in some time, designed specifically for use by their work truck division. Because of this, the engine has been constructed to be highly durable and capable of being worked on manually without causing major harm.
The Godzilla is one of the most powerful heavy-duty pickups available, boasting a 7.3L block engine that produces 11lbs more torque and 29 horsepower over its rival, the Ram 2500.
With such impressive power, it's no wonder why so many tuning companies are already developing supercharger systems for the engine. Both turbo-fed and conventionally supercharged setups are being considered, with both showing potential to produce over 1,000 horsepower while using its stock block and crank.
Whipple and Procharger have already designed supercharging systems for the Godzilla engine, with both capable of producing up to 1,500 horsepower with hard work and dedication from its user.
Merkel Racing Engines has taken Godzilla to new heights with their 780 hp mod featuring twin turbos in addition to factory rods and pistons. This is a dramatic improvement over the previous version which only produced 580 hp and 490 lb-ft of torque.
Dyno results can tell you how much power an engine is making, but it's essential to remember that different dynos and test procedures produce slightly different outcomes. This is especially true if the test is conducted on a hot day where vapor pressure is higher than usual - this could cause torque and power numbers to be overinflated, so make sure the test takes place when temperatures are normal and vapor pressure at their highest.
The Ford Super Duty lineup has seen the introduction of the 7.3L Godzilla engine, offering 430 horsepower and 475 lb-ft of torque. This 7.3-liter pushrod V8 is one of the largest displacement gasoline engines ever made for production vehicles, as well as Ford's first pushrod powerplant since the Modular V10.
This 7.3 liter naturally aspirated iron block motor was originally designed to power heavy work trucks that could tow large loads or move cargo. It was meant to be a reliable workhorse that didn't need much upkeep.
As this engine's popularity grows, reports have surfaced that Ford may be testing a twin turbo version of it in at least two of their F-Series pick-up trucks. These reports come from sources familiar with Dearborn's research and development efforts.
Ford could potentially develop a twin-turbo version of their Godzilla V8 for the 2022 Raptor and possibly even the 2020 Shelby GT500, which currently sports 5.2 liters. If Ford were to fit this version of their engine into these cars, it would add significant power without adding too much weight.
This new twin-turbo powerplant is expected to produce over 1,000 horsepower, more than what the Godzilla currently produces in stock form. This gives it an advantage over rivals such as Ford GT and Shelby GT500 which both boast EPA-certified outputs of 700 hp or less.
Although this engine may be an anomaly in the current lineup, it's being developed to make a strong impression. It features gas-burning capabilities with modern features that will be perfect for truck enthusiasts looking for maximum performance from their vehicle.
We're eager to see where this engine's performance capabilities take us in the future! Stay tuned as we keep you informed on our progress as we go along!
Ford's 7.3L Godzilla engine, first featured in the F-Series Super Duty truck last year and quickly gained popularity. Its pushrod-driven valvetrain keeps its size under control while modern components such as variable valve timing and fuel injection help keep costs down.
The 7.3L Godzilla is an iron block monster, producing 430 horsepower and 475 lb-ft of torque. It boasts a sturdy iron block, forged steel crankshaft, and six-bolt main journal configuration for reliable performance even under high boost conditions.
Performance enthusiasts have begun to explore the capabilities of the 7.3L Godzilla in the aftermarket, pushing it past 600 horsepower with basic modifications and over 1,450 horsepower with a fully built twin-turbo setup. Some tuners have even achieved 900 horsepower on stock sealed units without forced induction - and progress is being made!
Brian Wolfe from Merkel Racing Engines has been dyno testing the 7.3L in various combinations, from mildly modified to fully ported and built with boost. Recently he took it up a notch by producing 1450 horsepower on an entirely custom supercharged Godzilla crate engine.
Wolfe achieved this remarkable output by upgrading the stock forged steel crank with MGP aluminum rods, Wiseco 12.5:1 compression pistons and Jesel keyed lifters and rocker arms. He also created a custom-ground solid roller camshaft with over.900 inch lift and 275 degrees of duration at.050-inch - an enormous improvement from the factory's 5.3L V8.
Only weeks after finishing his supercharged Godzilla, Wolfe brought it to Willis Racing garage in Indianapolis for a test run on the dyno. Thanks to his ProCharger package and Foxbody Mustang, he was able to produce an astounding 5.01 seconds out of the eighth-mile.
With this engine's impressive power potential, we wouldn't be surprised to see it appearing in more muscle cars as a crate engine. At under $10,000 cost, this under-the-hood powerplant offers incredible value for your money - an unbeatable deal!
Only three months after Ford filed to trademark "Megazilla," we saw its evolution in the form of an even more powerful Godzilla V8 engine. Still displacing 7.3 liters as before, but featuring numerous upgrades like Mahle pistons, forged Callies H-Beam connecting rods, CNC-machined heads and a low-profile intake manifold from Ford Performance; total output now stands at an incredible 615 horsepower and 640 pound-feet of torque!
Brian Wolfe has already constructed several versions of the engine, from a lightly modded 600-horsepower model to an insane 1450 horsepower supercharged monster. Merkel Racing also acquired a twin turbo Godzilla and has not shied away from pushing its performance limits either.
Other than racers and hotrodders, the 7.3-liter Godzilla has also caught the attention of street enthusiasts. Cleetus McFarland and crew recently had the chance to test it out on the dyno with their 'McFlurry' Fox body, and they managed some impressive numbers!
The 7.3-liter engine was designed to fit into older Ford pickups and vans, but could potentially serve a wider range of applications with application-specific swap kits available in the future. Evan Smith, president of ProCharger, reported that they have been working on turbo kits for this engine and expect them to be released shortly.
When we spoke with him about the engine's bottom end, he noted that it is suitable for mild performance applications. Any high-horsepower or racing builds would need upgraded connecting rods and pistons. He cautioned us that adding significant horsepower can impact bearing and ring life as well as head gasket sealing.
This engine looks to be an instant hit for Ford OE customers and the hot rod community alike. With plenty of potential horsepower, its performance parts and finely tuned cam should make it a great choice for anyone building either a monster truck or restomod with powerful horsepower.
