ENJOMOR Built an INSANE V8 Race Car | 2026 Model Car Show | Stirlingkit

The complete turbocharged V8-9078 build that turned heads

ENJOMOR made its debut at the 2026 Model Car Show with a complete turbocharged V8 engine powered race car—and it immediately became the centerpiece of the exhibition. Visitors crowded around it all day, asking questions, taking photos, and discovering what a real, working precision engine looks like when properly integrated into a complete system.

It's a white aluminum chassis powered by the V8-9078—a fully functional 78cc V8 with turbocharging that delivers 4.5 kW of baseline power, bumped 30-50% higher with boost engaged. Here's how we built it.

What Powers This Build

Enjomor V8-9078. V-configuration, eight cylinders, 78cc displacement. Four-stroke cycle. Runs up to 12,000 rpm, outputs 4.5 kW baseline. On paper it's solid. In real life, it's the foundation of something much more interesting.

DOHC architecture—dual overhead cam—with 4 valves per cylinder. Two intake, two exhaust. That's 32 valves total. Why does that matter? Breathing efficiency. The more effectively air moves in and exhaust moves out, the more power the engine can generate per cycle. On this build, the timing belt runs exposed so you can watch the cam-to-crank synchronization happen in real time.

Eight spark plugs—one per cylinder—controlled by a CDI ignition system with Hall-effect distributor. Every spark fires at the exact optimal moment. That precision is what separates good combustion from efficient combustion.

Then We Added Boost

That black turbocharger on top? That's where the real magic happens. Most people know the concept—exhaust spins a turbine, which drives a compressor that forces more air into the engine. Sounds simple. The engineering is not.

More air means more oxygen for combustion. Add proportionally more fuel, and each explosion is bigger. Simple physics. The result: 30-50% more power output from the exact same engine. You read that right. One component addition transforms the performance tier entirely. On the dyno it reads as a massive jump. In person, it sounds and feels like a completely different engine—aggressive, responsive, purposeful.

But here's the catch—compressed air heats up. Hot air is less dense, which kills some of your efficiency gains. Solution: an integrated intercooler. It cools the boost air before it enters the engine. Cooler, denser air burns more completely. It's the difference between good power and optimized power.

Cross-Flow Exhaust Layout

The V8-9078 uses a cross-flow exhaust header layout where the left and right cylinder banks are routed through separate, interwoven paths before merging into the turbocharger.

Instead of directing all eight cylinders into a single immediate collector, each bank is handled independently, helping maintain a clearer and more organized exhaust routing structure.

This layout also creates a more structured mechanical appearance, making the separation and recombination of flow from both cylinder banks visually easy to understand.

In this model, the design is used to demonstrate a realistic V8 exhaust routing concept and to enhance the overall mechanical depth of the engine assembly.

The layout is based on high-performance engine design principles, where exhaust flow is managed separately by cylinder bank before being brought back into a unified system.

Cooling and Lubrication

Water cooling. A pump continuously circulates coolant through the block and cylinder head, absorbing combustion heat and transferring it to an external radiator. Why water instead of air? Thermal efficiency and temperature stability. You can sustain higher power output without overheating.

Lubrication is independent. An oil pump forces SAE 0-20W 2T oil through precision-drilled galleries in the block. Every critical surface—main bearings, rod journals, cam lobes, piston pins—gets continuous oil film. About 60mL total, circulated and reclaimed.

Piston rings: three per piston. Compression ring seals combustion pressure. Taper ring provides secondary sealing and oil control. Oil ring scrapes excess oil from the cylinder wall. This combination maintains compression while preventing oil from entering the combustion chamber. The design works because it's been refined for decades.

Crankshaft support: five main bearings. Three large diameter bearings span the center section. One small bearing at each end. This five-point architecture resists deflection at extreme RPM. Cast as a single unit, gun-drilled for oil supply, built to handle sustained high-load cycles.

Start It Up

3548 brushless starter, 24V system. Turn the key. The motor cranks the engine. CDI fires ignition on schedule. It lights. No hand-crank complexity, no auxiliary equipment. Ignition system runs on 12V, isolated from the starter circuit.

The Chassis Was Engineered for This

You could bolt an engine to any frame. This frame was designed specifically for a turbocharged V8. Fully welded aluminum tube chassis—light enough for responsive handling, rigid enough to resist torsional loads without deflection.
Layout is straightforward: two primary longitudinal members run the full length, front axle to rear axle. Cross-members and gussets are strategically welded to maintain geometry and resist twisting. This design has been proven in race cars for decades because it distributes load efficiently. Engine torque stays balanced. Frame stays square.

Nothing to Hide

The v8 engine sits completely exposed. No cover, no shroud. Polished aluminum head and block. Eight exhaust tubes feeding an integrated manifold. Exposed timing belt with visible pulleys. Intake manifold. Cooling hoses. And that black turbocharger mounted prominent on top. Every component is visible. Every weld joint is clean. Every precision detail is exposed.

There's function behind the form. First—cooling. Uncovered, the engine has ambient air moving freely across every surface. Head, block, turbo housing, intercooler. No hot spots develop. Sustained high-load operation stays temperature-stable.
Second—maintenance. Need to clean the engine? Change a sensor? Replace a hose? Everything is directly accessible. No plastic panels, no harness disconnects. Work happens at component level, efficiently.

Third—presence. That black turbo sitting high on the engine isn't subtle. It announces, immediately, that this is a forced-induction system. The precision of the fabrication is obvious. At the show, visitors spent more time around this engine than anywhere else. That wasn't an accident—it was design.

Suspension and Wheels

Front suspension is double-A-arm independent with hydraulic dampers. Each wheel operates independently. Turns are flat, rough surfaces are absorbed, body roll stays minimal. Dampers are tuned for the sweet spot between comfort and control.
Rear is a solid axle with multi-link suspension. Simpler, stronger. Better traction handling when a turbocharged engine is demanding grip. Both ends run oil-filled shocks tuned for the performance envelope.

All-terrain tread tires with deep lugs. Grip is consistent on concrete, brick, dirt. Lightweight aluminum wheels in black provide visual contrast against the white body.

Power to the Ground

The 10mm output shaft connects to a transmission. The transmission's job is gear selection—matching the engine's torque and speed output to what the wheels need at any given moment. Low speeds demand high torque. High speeds need higher wheel RPM relative to engine RPM.

Power flows from the transmission through a differential to all four wheels. The differential is essential—when cornering, outside wheels travel a longer distance than inside wheels. Without a differential, all wheels would try to turn at the same speed, and the tighter wheels would slip. A differential allows speed variation while distributing power evenly.
Every connection is precision-machined. Zero play. Zero slop. That means 4.5 kW—or more, with boost—actually reaches the contact patches.

Electrical System

Wiring is color-coded and bundled. The CDI ignition module is standalone. The starter is compact and purpose-built. Sensors—oil temperature, coolant temperature, RPM—connect through aviation-grade connectors. The architecture is modular. If something fails, you can identify and isolate it quickly. Diagnosis is straightforward.

Why This Matters

The Enjomor V8 engine V8-9078 is impressive in isolation. A lot of engineering lives in that block. But this car proves a bigger point: pair a precision engine with intelligent chassis engineering, and you get something exponentially better.

A well-designed frame holds the engine stable and rigid. Proper cooling keeps temperatures safe under load. Suspension geometry translates power into actual speed and control. Clean electrical architecture ensures reliable starting and precise ignition timing. These aren't afterthoughts. They're the foundation.

This is what you can build with the V8-9078. Drop it into an RC car. Mount it in a boat. Power a scale tank model. An off-road buggy. A flying drone platform. The engine is the starting point. The engineering you build around it determines whether you get a toy or a legitimate performer.

White bodywork with racing stripes. Exposed, precision-finished engine. Black turbo positioned prominently. Everything about this car communicates one thing: serious craftsmanship. And that's exactly what it is.

The V8-9078 is available now. We're here to help you build something just as insane. What's your next project?
