What Car Has The Most Hp Stock

Alright, let's talk about raw horsepower. Specifically, which production car currently reigns supreme in the horsepower wars straight from the factory. We're not talking about modified beasts or limited-run hypercars that barely qualify as road-legal. We're focusing on commercially available vehicles that you can (theoretically) walk into a dealership and purchase. The answer, definitively, is the Dodge Challenger SRT Demon 170.

Dodge Challenger SRT Demon 170: King of Horsepower

This isn't just some incremental upgrade; it's a monumental leap in power. The Demon 170 isn't just the most powerful car currently produced, it's a testament to the dedication of engineers pushing the limits of internal combustion.

Key Specs and Main Parts: The Heart of the Beast

The Demon 170 centers around a heavily modified version of the 6.2-liter supercharged Hemi V8, now officially designated as the "Hellcat Redeye High-Output" engine, albeit with significant upgrades. Here's a breakdown:

• Engine: 6.2L Supercharged High-Output Hemi V8 (modified Hellcat Redeye)
• Horsepower: 1,025 hp (on E85 fuel); 900 hp (on E10 gasoline)
• Torque: 945 lb-ft (on E85); 810 lb-ft (on E10)
• Supercharger: 3.0L IHI supercharger (larger than the standard Hellcat's) with a 3.02-inch pulley
• Fuel System: Upgraded fuel injectors, fuel rails, and fuel pump to handle the massive fuel demand of E85. E85 refers to a fuel mixture that is 85% ethanol and 15% gasoline.
• Engine Block: Strengthened and modified to withstand the immense forces generated.
• Crankshaft and Pistons: Forged steel crankshaft and forged aluminum pistons, designed for high-stress environments.
• Transmission: TorqueFlite 8HP90 8-speed automatic transmission, heavily reinforced to handle the power.
• Driveshaft: Upgraded driveshaft to handle the increased torque output.
• Rear Axle: A sturdier rear axle is essential to transmit the power to the wheels.

Let's dive a bit deeper into some of the critical components:

Supercharger: The 3.0-liter supercharger forces air into the engine cylinders at a much higher pressure than atmospheric pressure. This is called forced induction. More air means more fuel can be burned, resulting in a significant increase in power. The smaller pulley on the supercharger spins it faster, increasing boost pressure.

Fuel System: The ability to run on E85 is crucial to achieving the 1,025 hp figure. E85 has a higher octane rating and a higher cooling effect than gasoline, allowing for more aggressive tuning and higher cylinder pressures without the risk of detonation (engine knocking). Detonation is the uncontrolled explosion of the air-fuel mixture in the cylinder, which can severely damage the engine.

Engine Internals: The forged crankshaft and pistons are significantly stronger than their cast counterparts. This is necessary to withstand the extreme stresses generated by the high horsepower and torque output. Forging is a manufacturing process that involves shaping metal using localized compressive forces. It results in a denser, stronger material.

How It Works: Harnessing the Power

The Demon 170's engine operates on the same principles as any other internal combustion engine – intake, compression, combustion, and exhaust. However, the sheer volume of air and fuel being processed, and the pressures involved, are on a completely different scale.

The supercharger forces a large volume of air into the cylinders. The upgraded fuel system delivers a massive amount of fuel, especially when running on E85. This rich air-fuel mixture is then compressed by the pistons and ignited. The resulting explosion drives the pistons down, which in turn rotates the crankshaft. This rotational force is then transmitted through the transmission, driveshaft, and rear axle to the wheels, propelling the car forward with astonishing acceleration.

The engine control unit (ECU) plays a crucial role in managing this process. It monitors various sensors, such as air-fuel ratio, throttle position, and engine speed, and adjusts fuel delivery, ignition timing, and supercharger boost to optimize performance and prevent engine damage. The ECU is essentially the brain of the engine.

Real-World Use: Basic Troubleshooting Tips

While the Demon 170 is a marvel of engineering, it's still a machine, and like any machine, it can experience problems. Here are a few basic troubleshooting tips:

• Poor Performance/Check Engine Light: This could be caused by a variety of issues, such as a faulty sensor, a clogged fuel injector, or a problem with the supercharger. Use an OBD-II scanner (On-Board Diagnostics) to retrieve the trouble codes and diagnose the problem. OBD-II scanners read diagnostic codes from the car's computer.
• Rough Idle: A rough idle could be caused by a vacuum leak, a dirty throttle body, or a faulty ignition coil.
• Excessive Fuel Consumption: Running on E85 will naturally result in higher fuel consumption than gasoline. However, if you notice a sudden and significant increase in fuel consumption, it could indicate a problem with the fuel system or the engine management system.
• Overheating: This engine generates a lot of heat. Ensure the cooling system is functioning properly, including the radiator, water pump, and cooling fan.

Note: Due to the complexity and high performance nature of this vehicle, any significant repairs or modifications should be performed by a qualified technician with experience working on high-performance engines.

Safety: Handle with Respect

The Demon 170 packs an incredible amount of power. This is not a car for inexperienced drivers. Here are a few safety considerations:

• Tires: High-performance tires are essential for handling the power of the Demon 170. Ensure the tires are in good condition and properly inflated. Always use tires with a sufficient load rating for the vehicle.
• Brakes: The brakes are just as important as the engine. Ensure the brake system is in good working order, including the brake pads, rotors, and brake fluid.
• Electronic Stability Control (ESC): The Demon 170 is equipped with ESC, which helps to prevent loss of control. However, ESC is not a substitute for responsible driving.
• Fuel System: E85 is a flammable liquid. Handle it with care and avoid spills.
• Supercharger: The supercharger operates at high speeds and temperatures. Avoid touching it while the engine is running or immediately after the engine has been turned off.

Working on the fuel system can be particularly risky due to the high pressure and the flammability of the fuel. Always disconnect the battery and relieve fuel pressure before working on any part of the fuel system.

The high-performance components within the engine are also sensitive and require specialized tools and knowledge for repair. Improper handling can lead to serious damage or injury.
