Step 1: Understand Your Goals

• Identify your performance goals for your vehicle.
• In Daniel's case, the objective was to break the quarter mile record without using nitrous or turbos.
• Research existing records to set a realistic target.

Step 2: Plan Your Modifications

Create a list of performance upgrades that can enhance your vehicle's capabilities. Daniel's G37 included

• Mike Upton 3-inch intakes with velocity stacks/ram airs for better airflow.
• ISR longtube headers for improved exhaust flow.
• Tomei Y pipe and single exit exhaust for enhanced sound and performance.
• Upgraded fuel system components like the Walboro 255 fuel pump and GTR injectors for better fuel delivery.
• JWT C2 cams to increase engine efficiency.
• Ported upper and lower manifolds for reduced airflow resistance.
• 75MM throttle bodies kit from Simplistic Garage for improved throttle response.
• A 3.7 LSD differential and Bell Raceworks diff brace for better traction.
• Z1 urethane diff bushings to minimize slippage.

Step 3: Optimize Fuel and Tuning

• Choose the right fuel for your performance needs. Daniel used E85 due to its higher ethanol content which can yield more power.
• Work with a professional tuner for optimal results. Daniel’s car was tuned on ECUTEK by Martin (RS-Enthalpy).
• Ensure the tuning matches the modifications for maximum efficiency and performance.

Step 4: Prepare for Track Day

Before heading to the track, perform a thorough inspection of your vehicle

• Check tire pressure and tread for optimal grip.
• Ensure all modifications are secure and functioning.
• Test the vehicle in a safe environment to confirm performance enhancements.

Step 5: Execute at the Track

Focus on your driving technique

• Practice launching techniques to maximize acceleration off the line.
• Monitor your shifts and maintain optimal RPMs during the run.
• Record your times to track improvements. Daniel broke the world record twice during his outings, showcasing the importance of persistence and practice.
