‪@BabyDRT‬ chats about his 760 HP dodge challenger r/t 5.7L hemi build with #moparbro fred_eazy21
The setup you've described for your 2009 Dodge Challenger RT with a 5.7L Hemi stroked to a 392 and equipped with a Magnuson Magnum TVS2650 supercharger is an impressive and high-performance build. Let's break down the components and what they contribute to your vehicle's performance:
5.7L Hemi Stroked to 392:
Stroking: Increasing the engine's displacement from 5.7 liters to 392 cubic inches (6.4 liters) typically involves installing a longer-stroke crankshaft, larger pistons, and matching rods. This increases the engine's capacity to draw in more air and fuel, boosting power and torque.
Benefits: More displacement usually results in greater low-end torque and overall horsepower, providing a significant performance boost over the stock configuration.
Magnuson Magnum TVS2650 Supercharger:
Supercharger Type: The TVS2650 is a twin-vortices series supercharger known for its efficiency and power delivery. It provides a consistent and linear increase in power across the RPM range.
Boost Pressure: This supercharger can produce significant boost levels, leading to substantial horsepower and torque gains. Exact boost levels will depend on your specific tuning and setup.
Intercooling: Many supercharger kits include an intercooler to cool the compressed air before it enters the engine, improving power and reliability.
760 HP:
Horsepower: With the combination of increased displacement and the TVS2650 supercharger, reaching 760 horsepower is plausible. This requires careful tuning, high-flow fuel injectors, an upgraded fuel pump, and potentially other supporting modifications like a high-performance exhaust system, and reinforced drivetrain components to handle the extra power.
Additional Considerations:
Tuning: A custom ECU tune is crucial to optimize the air-fuel mixture, ignition timing, and other parameters to safely and efficiently manage the increased power.
Cooling: Enhanced cooling systems (radiator, oil cooler, etc.) might be necessary to manage the additional heat generated by the higher power output.
Transmission and Drivetrain: Upgrades to the transmission, differential, axles, and driveshaft may be required to handle the increased power and torque without failure.
Brakes and Suspension: Enhanced braking systems and suspension upgrades can help manage the performance increase and ensure safety and handling are up to par.
This setup not only makes for a highly powerful vehicle but also requires attention to detail in supporting modifications to ensure reliability and longevity. Proper installation and tuning by experienced professionals are crucial to achieving the desired performance and maintaining the engine's health.
Achieving 760 horsepower (hp) from a Dodge Challenger R/T, which typically comes with a 5.7L HEMI V8 engine, requires a combination of performance upgrades. Here’s a comprehensive guide to reaching that power level:
1. Forced Induction
Supercharger or Turbocharger Kit:
Supercharger Kit: Installing a supercharger is one of the most effective ways to boost horsepower. Companies like ProCharger, Whipple, and Vortech offer supercharger kits for the 5.7L HEMI that can significantly increase power output.
Turbocharger Kit: Alternatively, a twin-turbo setup from companies like Hellion Power Systems can also achieve similar gains.
2. Engine Internals
Upgraded Internal Components:
Forged Pistons and Rods: To handle the increased power and boost, upgrading to forged pistons and connecting rods is essential for reliability.
Performance Camshaft: A more aggressive camshaft will allow for better airflow and higher RPM capabilities.
High-Flow Cylinder Heads: Ported and polished heads, or aftermarket high-flow heads, will improve the engine’s ability to breathe.
3. Fuel System
Enhanced Fuel Delivery:
High-Flow Fuel Injectors: Larger fuel injectors will be necessary to provide the increased fuel required for higher horsepower.
Upgraded Fuel Pump: A higher-capacity fuel pump will ensure adequate fuel pressure and volume.
4. Exhaust System
High-Performance Exhaust:
Headers: Long-tube headers will improve exhaust flow and reduce backpressure.
Exhaust System: A high-flow cat-back exhaust system will complement the headers and improve overall exhaust efficiency.
5. Tuning
ECU Tuning:
Custom Tune: A professional dyno tune is critical to optimizing the performance of all the new components. This will ensure the engine runs efficiently and safely at higher power levels.
6. Supporting Modifications
Additional Upgrades:
Supercharger Kit: ProCharger D-1SC or Whipple 2.9L.
Forged Pistons and Rods: Manley or Wiseco pistons, K1 Technologies connecting rods.
Performance Camshaft: COMP Cams or similar performance camshaft.
High-Flow Cylinder Heads: CNC ported stock heads or aftermarket options.
Fuel Injectors: Injector Dynamics ID1050x or similar.
