Have you been on the fence about having a remanufactured engine installed in your vehicle? Remanufactured engines are often misunderstood or surrounded by myths that don't accurately reflect their actual performance and benefits. To help you decide whether a remanufactured engine is right for you, here's a breakdown of some of the most common myths and Myth 1: Remanufactured Engines Are Lower Quality than New Engines One common misconception is that remanufactured engines are of lower quality compared to brand-new engines. However, remanufactured engines undergo a rigorous process that involves disassembly, inspection, replacement of worn or damaged parts, re-machining, and reassembly to meet or even exceed original manufacturer specifications. At RPM Engine & Machine, we follow strict industry standards and employ skilled ASE-certified technicians to ensure that the engines we remanufacture are high-quality and like new. We use superior parts and materials that surpass ... read more

When it comes to enhancing the performance of your vehicle's engine, one of the key considerations is head porting. Head porting is a specialized technique that involves modifying the intake and exhaust ports of the engine cylinder head. This process can have a profound impact on engine efficiency, ultimately translating into improved horsepower, torque, and overall performance. What is Head Porting and How Does it Work? Head porting is a precision machining process that focuses on reshaping and smoothing the intake and exhaust ports within the cylinder head. The goal is to optimize airflow, fuel atomization, and exhaust gas evacuation, all of which are crucial factors for efficient combustion. The process typically involves removing imperfections and restrictions in the ports. This can include enlarging and reshaping the ports, polishing surfaces, and ensuri ... read more

In many ways, the camshaft is the unsung hero of an engine. It dictates the power delivery, how an engine behaves, and the overall performance. Whether you’re a seasoned auto enthusiast or just starting to get into engine tuning, understanding the different camshaft options and how to choose one for your vehicle is crucial for optimizing your engine’s capabilities. The Basics of Camshafts The camshaft's primary function is to control the opening and closing of the engine's valves. This simple yet crucial task directly influences engine performance. The camshaft's profile, known as its "cam," determines valve timing, lift, and duration. Types of Camshafts There are several types of camshafts available, including: Stock Camshafts: Often found in factory engines, stock camshafts prioritize a balance between fuel efficiency, reliability, and performance. They're designed for everyday use and might ... read more

If you’re an automotive enthusiast or you’ve been looking into ways to optimize your vehicle’s performance, you’ve probably heard of dyno tuning. This precise and sophisticated process uses a dynamometer (aka “dyno”) to fine-tune a vehicle’s engine in order to improve its power and fuel efficiency—and enhance your overall driving experience. How Does Dyno Tuning Work? The dynamometer is a specialized machine that measures and analyzes the power and torque output of an engine under controlled conditions. Using this information, our dyno specialists can fine-tune various engine parameters, including the air-to-fuel mixture, ignition timing, and exhaust system settings. Dyno tuning involves several steps: We establish a baseline measurement of your vehicle’s horsepower, torque output, and other parameters by running it on the dyno. The sensors and data loggers collect information about the air-to-fuel ratio, exhaust temperatures ... read more
