Building a Dodge Challenger SRT Hellcat for drag racing with a Whipple supercharger involves several steps to ensure you maximize performance and reliability. Here's a detailed guide on how to approach this build:
1. Engine Upgrades
Whipple Supercharger: Install a Whipple 3.0L or 4.0L supercharger kit. These kits often come with everything needed, including the supercharger unit, intercooler, and necessary hardware.
Fuel System: Upgrade the fuel injectors and fuel pump to handle the increased fuel demand. Consider high-flow injectors and a high-capacity fuel pump.
Exhaust System: Install long tube headers and a high-flow exhaust system to reduce backpressure and improve exhaust flow.
Cooling System: Upgrade the radiator and add an intercooler for the supercharger to manage the extra heat generated by the increased power.
2. Drivetrain Upgrades
Transmission: Strengthen or upgrade the transmission to handle the increased power. Consider a high-performance automatic transmission or a beefed-up manual transmission.
Driveshaft: Install a stronger, one-piece driveshaft to handle the increased torque.
Differential: Upgrade to a high-performance limited-slip differential or a drag-specific differential.
3. Suspension and Chassis Upgrades
Suspension: Upgrade to adjustable coilovers and drag-specific shocks and struts. Consider installing traction bars or a four-link suspension setup for better launch control.
Brakes: Upgrade to high-performance brakes with larger rotors and better calipers to ensure you can stop efficiently after a high-speed run.
Chassis Stiffening: Add subframe connectors and a roll cage to stiffen the chassis and improve safety.
4. Tires and Wheels
Drag Radials: Install drag radials or slicks for the rear wheels to maximize traction.
Lightweight Wheels: Consider lightweight racing wheels to reduce unsprung weight and improve acceleration.
5. Tuning and Electronics
Engine Management: Get a custom tune for the ECU to optimize the performance of the supercharger and other upgrades.
Data Logging: Use a data logger to monitor and adjust performance parameters during testing.
Traction Control: Install a drag-specific traction control system to manage power delivery during launches.
6. Safety Equipment
Roll Cage: Install a roll cage to protect the driver in case of a rollover.
Racing Seats and Harnesses: Use racing seats and harnesses to keep the driver secure.
Fire Suppression System: Install a fire suppression system for added safety.
7. Testing and Tuning
Dyno Tuning: After installing all components, take the car to a dyno for tuning to ensure the engine is running optimally.
Track Testing: Test the car on the drag strip to fine-tune the suspension, tire pressures, and launch techniques.
Example Parts List
Whipple Supercharger Kit: Whipple 3.0L or 4.0L kit specific to the Hellcat.
Fuel Injectors: High-flow injectors (e.g., 1000cc or higher).
