This engine peaked at over 1,100 horses with minimal modifications

Ford’s Godzilla engine needs no introduction. The automaker introduced this in the Super Duty truck series not too long ago. This V-8 pushrod displaces 7.3 liters and makes 430 horses and 475 pound-feet of torque. But, it looks like the engine is a lot more capable than its rather subtle state of tune in the production engine form.

Ever since the company started offering it as a crate engine, builders have been trying to extract every ounce of power from it. Merkel Racing Engines decided to do the same, and with minimal mods, they were able to achieve four-digit power figures. Is this engine a beast or what?

The New York-based tuner dyno-tested the naturally-aspirated version of the engine first with an upgraded throttle body and OBR MAP calibration. This resulted in 540 horsepower, which is 120 ponies more than the factory-rated number. The Drive spoke to a crew member from Merkel Racing Engines and he said that post this, the crew fabricated a forced induction setup that involved a pair of 7875 VS Racing turbos, twin intercoolers, and 1,000 cc injectors.

The crew member reports that the peak torque is still unclear as the dyno couldn’t hold it at that low of an rpm, but it did show 1,037 pound-feet of torque at 5,400 rpm.

With 15 psi of boost, the engine hit a peak power of 1,114 ponies at 5,800 rpm. Mind you, these figures were achieved with the stock camshaft, rods, and pistons. The injectors had to be upgraded because the stock ones couldn’t go beyond 780-800 horses. The crew plans to install a Whipple supercharger and estimate a peak power output of around 1,500 horses. Phew!

Even Ford Is Working On Creating A Powerful Version Of The Godzilla

It’s not just the engine builders. Ford is also working with Whipple to make the Godzilla mill the next big thing.

Whipple has developed a 3.0-liter, Gen V, twin-screw supercharger head unit for the Godzilla engine.

This Stage 2 supercharger kit will help it produce 700 horses and 750 pound-feet of twist. It also includes a 132 mm oval intake throttle body that increases the airflow and a triple-intercooler setup with large cores. Instead of being used as an engine for performance, Ford will use it to travel with a load at higher speeds.

The Godzilla has a huge potential and we’re getting glimpses of it already. It’s only a matter of time before we see these shackles broken and see the engines in action in the real world. We also have our eyes set on Merkel’s 1,500-horsepower-iteration of this engine.

What do you have to say about the Godzilla engine and its prowess? Do you think the upcoming Raptor could be offered with one to take on the Ram 1500 TRX? Share your thoughts with us in the comments section below.
