Many people have many questions about the new TOYAN V8 engine launched by EngineDIY. We will answer them one by one to help consumers better understand this engine!

The new TOYAN FS-V800WGPC stands as a comprehensive upgrade to the classic FS-V800G, heralding a new era of technological advancement. Below, we delve into a detailed comparison of the two engines, uncovering their unique allure.

FS-V800G (Old) vs. FS-V800WGPC (New)

Here are the main differences between the two TOYAN V8 engines:

1. Appearance and Weight

The new TOYAN V8 engine is more compact and lightweight compared to the old model, with a design style that is closer to American aesthetics.

2. Distributor Optimization

The old model uses a suspended dual distributor, which has issues such as cylinder misfires, spark jumps, high adjustment difficulty, and unreasonable wiring.

The new model has been upgraded to a contact single distributor, which significantly reduces adjustment difficulty and makes wiring more standardized.

Additionally, the new model is equipped with a V8-specific CDI system, providing stable and reliable performance.

3. Optimized Performance Parameters

Displacement: Both models have a consistent 28cc (3.5cc×8) displacement for strong power output.

RPM Range:

Old Model: 3000-12500rpm, designed for high-speed operation.

New Model: 1950-8650rpm, optimized for smoother low-speed operation, resulting in better fuel efficiency and stability.

4. Water Cooling System Optimization

The new TOYAN V8 engine adopts a dual independent cooling system, significantly extending the engine's operating time.

5. Fuel Supply System Optimization

The new engine is equipped with a gasoline-specific carburetor, which not only improves engine stability but also significantly reduces fuel consumption, making starting smoother.

6. Air Filter Cover Optimization

The new air filter cover is equipped with a cold start choking device, effectively improving the issue of difficult cold starts.

7. Electric Start Optimization

The electric start system of the new TOYAN V8 engine has been optimized, with a reduction gear added to the output shaft and a relay added to the motor, effectively protecting the motor switch and battery from overload damage, making electric starting more effortless.

8. Engine Internal Optimization

The new engine adopts a top-link valve train and gear-driven timing system, with adjustable valve clearance, making the timing mechanism more stable. This design eliminates the risk of timing errors and makes maintenance more convenient.

9. Dual Piston Ring Optimization

The dual piston ring design of the new TOYAN V8 engine effectively ensures cylinder pressure, reducing the occurrence of cylinder misfires.

10. Camshaft and Support Structure

The new engine adopts a high-angle stroke camshaft and a five-point cam support structure, further enhancing engine performance.

11. Crankshaft and Ignition Sequence:

The new TOYAN V8 engine features a one-piece processed five-point supported 90° cross crankshaft, with an ignition sequence of 1-5-4-3-6-8-7-2.

Hope the above information helps you better understand the main differences between the two TOYAN V8 engines.
