Ford Model T or the turbocharger? You might find it surprising—just as I was when I looked it up—to discover that the turbocharger is actually somewhat older. Swiss engineer Alfred Buchi may have filed a patent for exhaust-driven turbines as early as 1905, but such an advanced gadget was far from Henry Ford’s intentions when he produced the Model T in 1908. Now, over a century later, these two groundbreaking innovations have been combined in a workshop by an individual.
That individual is Merlin Johnson, a seasoned hot-rod enthusiast without a doubt. He operates Merlin’s Old School Garage on YouTube. Johnson possesses a Ford Model T featuring an authentic 177-cubic-inch four-cylinder engine that generated 20 horsepower upon its initial release. He also has a turbocharger from a compact Kubota tractor. You can likely deduce the reasoning that led him to merge the two.
Physically attaching the power booster was straightforward. Johnson removed the original cast iron exhaust manifold from the engine, cut an opening, crafted a flange, and secured the turbo to that. However, the challenging aspect was providing lubrication for the boosting device.
Model T engines lack oil pumps. Instead, there is a tube that transports oil from the front of the engine straight to the transmission, as part of a “dipper slinger” mechanism. For the turbo to function, Johnson needed to devise a method to tap into this system, or it would spool to its unavoidable (and instantaneous) demise. He tackled this problem by utilizing centrifugal force from the flywheel to drive oil through a copper tube that feeds into the turbo. A basic siphon drain then channels the oil back into the engine.
A quick startup in the garage looked promising, with no oil leaking from the makeshift solution, and the test drive confirmed that it operates effectively. Johnson’s initial cruise around the neighborhood showcased significant performance improvements, with a top speed of 28 mph—a five mph gain over stock. He noted it peaked at around six pounds of boost, so it’s reassuring to recognize that a standard Model T can withstand at least that much without going kaput or kablam.
Will this Model T Ford operate with a Turbocharger?
Don’t expect to see a multitude of other Model T owners boosting their sidevalve engines. This method is certainly not the cheapest or most efficient means to enhance speed. Nonetheless, it’s intriguing to observe how the century-old engine reacts to a little extra energy. The first factory-turbocharged vehicle wouldn’t appear for nearly four decades, as General Motors launched the Oldsmobile Jetfire in 1962, and it’s not as if the Model T was engineered for high performance.
That has never deterred individuals from modifying them in the past, and as you can see, it isn’t hindering hot-rodders today, either.

**Assessing the Performance of a Turbocharged Century-Old Ford Model T Engine**
The Ford Model T, launched in 1908, transformed the automotive sector with its affordability and assembly line production methods. As one of the inaugural cars to be manufactured on an assembly line, it established the foundation for modern automobiles. Nonetheless, the initial engine design, a 2.9-liter inline-four, generated a humble 20 horsepower, adequate for its era but lacking the performance benchmarks of current vehicles. In recent times, enthusiasts and engineers have investigated the possibilities of retrofitting classic engines with modern advancements, like turbocharging, to boost performance while preserving the vehicle’s historical character. This article examines the performance of a turbocharged Ford Model T engine, taking into account several elements such as power output, efficiency, drivability, and historical significance.
**1. Engine Specifications and Adjustments**
The original Ford Model T engine features a straightforward, durable configuration with a cast iron block and overhead valves. When adding a turbocharger to this engine, multiple adjustments are required to cater to the enhanced air and fuel intake. Important changes include:
– **Turbocharger Choice**: Selecting the appropriate turbocharger is crucial. A compact, high-efficiency turbo that can spool rapidly is optimal for the Model T engine’s low displacement.
– **Fuel System Upgrade**: The original carburetor may require replacement or modification to accommodate the increased fuel demands. A contemporary fuel injection system can deliver improved fuel atomization and efficiency.
– **Upgrading Internal Components**: To endure the elevated power and pressure, internal parts such as pistons and connecting rods might need to be reinforced with forged materials.
– **Cooling System Improvements**: A turbocharged engine produces more heat, requiring an upgraded cooling system to mitigate the risk of overheating.
**2. Performance Metrics**
Upon completion of the turbocharging modifications, evaluating the performance of the turbocharged Model T engine involves several crucial metrics:
– **Power Output**: A turbocharged Model T engine can substantially enhance horsepower. Depending on the size of the turbocharger and boost levels, power output may escalate from the original 20 horsepower to a range of 60 to 100 horsepower or more.
– **Torque Enhancement**: Turbocharging typically boosts torque, especially at lower RPMs, making the vehicle more responsive and enjoyable to operate.
– **Acceleration and Maximum Speed**: With the increase in horsepower and torque, the Model T’s acceleration improves dramatically. The maximum speed may also rise, potentially reaching 70 mph or greater, compared to the original maximum speed of about 45 mph.
– **Fuel Efficiency**: Turbocharging can enhance fuel efficiency under certain circumstances, as the engine can perform more efficiently at lower throttle settings. However, this advantage can fluctuate based on driving styles and tuning.
**3. Drivability and Handling**
The driving experience of a turbocharged Model T is markedly different from that of the original. The additional power can make the vehicle more exciting to drive, but it also necessitates careful consideration of the following:
– **Transmission Compatibility**: The stock transmission may struggle with the added power. Upgrading to a more durable transmission can improve drivability and dependability.
– **Suspension and Braking**: Enhancements to the suspension and braking systems are necessary to accommodate the heightened speed and power, ensuring safety and control.
– **Weight Distribution**: Incorporating a turbocharger and its associated components may affect the vehicle’s weight distribution, thus influencing handling dynamics.
**4. Historical Context and Preservation**
While turbocharging a Model T can boost its performance, it poses questions regarding historical preservation. Enthusiasts must find a balance between the pursuit of modern performance and the necessity of preserving the vehicle’s historical integrity. Some may opt to keep the modifications reversible, allowing for the option to restore the original engine if preferred.
**Conclusion**
Assessing the performance of a turbocharged century-old Ford Model T engine uncovers a captivating blending of history and modern innovation. The promise of increased horsepower, torque, and overall drivability makes this project enticing to automotive enthusiasts. However, it is crucial to undertake such modifications with due respect for the vehicle’s heritage, ensuring that the essence of the Model T is maintained while embracing contemporary engineering advancements.
