Nitrous engines produce some serious horsepower and require a serious torque converter to handle it. B&M nitrous Holeshot torque converters can handle up to 650 hp and are built with the same features as the other B&M Holeshots, with the addition of anti-balloon plates that allow these converters to stand up to the instant horsepower that nitrous delivers. Converters with higher-than-stock stall speed let your ride accelerate better from a dead stop and allow the vehicle to idle better when a big cam is used. Fully furnace brazed, heavy-duty, needle-bearing thrust packages and new turbine hubs are the key features of these converters, along with the anti-balloon plates. These are serious converters for serious street performance cars.

These Powertrax no-slip traction systems are the latest design in traction-adding differential technology. They combine the smooth operation of a limited-slip differential with the traction performance of a locking differential. A precise synchronization mechanism eliminates the ratcheting sounds typical of other locking differentials. Special gear and spring designs reduce the backlash and, therefore, the driveline windup. Only ultra-strength material that is 67 percent stronger than titanium is used. Installation is simple because no ring and pinion setup is required. In addition, no special tools or oils are needed. Step-by-step, model-specific instructions are provided with every kit.

Hays steel flywheels are engineered to handle extreme-duty applications and designed to take the punishment of today's high-horsepower engines. They are CAD-engineered and precision CNC-machined to strict tolerances. Available in weights up to 50 lbs. for specialized applications, most Hays flywheels are drilled with both the Borg and Beck and Long-style clutch patterns. Upgrade to a precision-machined and engineered Hays billet steel flywheel. Features include: * SFI-approved--legal for use in racing classes that require SFI certification * CNC-machined from certified billet steel for maximum strength and durability * CAD-designed for optimum performance and reliability * Offered in internal, external, or neutral (zero) balanced versions * Available for a wide variety of engines Note: When choosing a flywheel, remember that a heavier flywheel stores more energy. A heavy car requires more power (or inertia) to launch without bogging the engine and needs a heavier flywheel. Lighter flywheels create less inertia at launch, but will accelerate faster through the gears.
