To convert a Ford Mustang into a serious drag racing machine, there are numerous upgrades and modifications you can make. These range from basic bolt-ons to full chassis and drivetrain overhauls, depending on how fast you want to go and what class you’re racing in.
Powertrain Modifications
Goal: Maximize horsepower and torque for quick acceleration.
- Forced Induction: Superchargers (e.g., Vortech, ProCharger) or turbochargers significantly increase power.
- Engine Build: High-compression pistons, forged internals, stroker kits (e.g., 347ci for 302), ported heads.
- Fuel System: Bigger injectors, high-flow fuel pump, fuel pressure regulator, return-style fuel systems.
- ECU Tuning: Dyno tuning or standalone ECU for precise control of fuel, timing, and boost.
- Nitrous Oxide: A well-set-up nitrous system for instant power (especially common in bracket racing).
Drivetrain Upgrades
Goal: Handle increased power and get it to the ground efficiently.
- Transmission: TKO, TH400, Powerglide, or a built 4L80E or 6R80; manual or auto depending on preference.
- Torque Converter / Clutch: High-stall converter (auto) or performance clutch (manual).
- Driveshaft: Lightweight aluminum or carbon fiber; 1-piece for reduced rotational mass.
- Rear Axle: Ford 9” or upgraded 8.8” with spool, locker, or limited-slip differential; 31- or 35-spline axles.
Suspension and Chassis
Goal: Improve traction, weight transfer, and straight-line stability.
- Front Suspension: Lightweight K-member, coilovers, caster/camber plates.
- Rear Suspension: Adjustable control arms, anti-roll bar, panhard bar or Watts link.
- Shocks/Struts: Double-adjustable drag shocks (e.g., QA1, Strange, Viking).
- Subframe Connectors: Weld-in connectors to stiffen the chassis.
- Tubular Components: For weight savings and improved geometry.
Tires and Wheels
Goal: Maximize grip and reduce rolling resistance.
- Drag Slicks or Radials: Bias-ply slicks or DOT-legal drag radials (e.g., Mickey Thompson ET Street).
- Skinnies Up Front: Narrow front wheels to reduce rolling resistance and weight.
Weight Reduction
Goal: Reduce mass to improve power-to-weight ratio.
- Remove rear seat, sound deadening, HVAC, and interior trim.
- Fiberglass or carbon fiber hood, doors, decklid.
- Lexan windows.
- Lightweight racing seats and battery relocation to rear for balance.
Safety Equipment (Required for Fast Cars)
Goal: Meet NHRA or local track rules and stay protected.
- Roll cage (6-point or 10-point, depending on ET).
- Driveshaft loop.
- Battery cutoff switch.
- Harnesses, fire extinguisher, fire suit for faster classes.
Electronics
Goal: Improve control, monitoring, and consistency.
- Line lock for staging.
- Two-step rev limiter and transbrake (automatic).
- Data logger and shift light.
- Wideband O2 sensor, boost controller, AFR monitoring.
