Crx Type R B18: Achieving a 9-Second Quarter Mile
The Honda CRX Type R, even in its stock form, is a highly desirable car for its lightweight chassis and rev-happy engine. But pushing it to achieve a blistering 9-second quarter-mile time requires a significant investment in modifications and a deep understanding of performance tuning. This article delves into the intricacies of building a CRX Type R B18 capable of such impressive speed, addressing common questions and exploring the key components that make it possible.
What modifications are needed to achieve a 9-second quarter mile in a CRX Type R with a B18 engine?
Reaching a 9-second quarter-mile in a CRX Type R with a B18 engine demands a comprehensive approach, going far beyond simple bolt-ons. It necessitates a meticulously planned build focusing on maximizing power, minimizing weight, and optimizing traction. Key modifications typically include:
-
Engine Modifications: This is where the bulk of the power increase comes from. Expect extensive internal work, such as forged internals (pistons, connecting rods, crankshaft), a high-performance camshaft, upgraded headwork (porting and polishing, larger valves), and a high-flow intake manifold. Forced induction (turbocharging or supercharging) is practically essential for achieving a 9-second pass. A significant upgrade to the fuel system, including larger injectors and a high-pressure fuel pump, will be necessary to support the increased power demands.
-
Drivetrain Upgrades: The stock transmission and differential won’t withstand the extreme power and torque. A strengthened transmission (possibly a custom-built unit) and a limited-slip differential are crucial to efficiently transfer power to the wheels. A lightweight driveshaft is also beneficial for reducing rotational inertia.
-
Suspension and Chassis: To handle the immense power and maintain stability at high speeds, upgraded suspension components, such as coil-overs with adjustable dampening and stiffer sway bars, are necessary. Reinforcement of the chassis is often needed to withstand the added stress. Lightweight wheels and high-performance tires are crucial for optimal grip and traction.
-
Weight Reduction: Every ounce counts in drag racing. Removing unnecessary weight (interior components, sound deadening material) contributes significantly to improved acceleration. Utilizing lightweight aftermarket parts where possible further enhances this.
What is the average horsepower needed for a 9-second quarter mile in a CRX Type R?
There's no single magic number for horsepower, as the time is influenced by factors beyond horsepower, such as weight, traction, and driver skill. However, a well-built CRX Type R B18 aiming for a 9-second quarter-mile would likely require 600-700 horsepower at the wheels, or significantly more at the crank, depending on drivetrain losses. This substantial horsepower necessitates a highly tuned forced induction setup, meticulously calibrated for optimal performance.
How much does it cost to build a 9-second CRX Type R B18?
The cost of building a 9-second CRX Type R B18 is substantial and highly variable. It easily ranges from $20,000 to $50,000 or more, depending on the quality of parts, the extent of custom fabrication, and the level of professional assistance required. This excludes the cost of the car itself. Remember that this is a serious undertaking requiring specialized knowledge and skilled labor.
What are the potential risks and challenges involved in building a 9-second CRX Type R B18?
Building a car capable of running a 9-second quarter-mile is inherently risky. The immense power and stress placed on the engine and drivetrain components significantly increase the chances of catastrophic failures. These could include engine blowouts, transmission failures, and differential failures. Furthermore, improper tuning or inadequate safety measures could lead to accidents. This project requires extensive expertise in engine building, tuning, and chassis dynamics.
What type of turbo setup is typically used for a 9-second CRX Type R?
A 9-second CRX Type R usually employs a large turbocharger capable of producing significant boost pressure. The specific turbocharger chosen depends on the desired power output and tuning strategy. It’s vital that the turbo is matched to the engine’s capabilities and the overall tuning goals. Supporting components like upgraded fuel delivery, efficient intercooling, and a robust exhaust system are also critical to the success of the turbo setup.
This article provides a general overview; achieving a 9-second quarter mile requires a high level of expertise and considerable resources. Consult with experienced engine builders and tuners to properly plan and execute such an ambitious project. Safety should always be the top priority.
