Many people love to tune their engines. Some even take their tuning to the extreme, making their cars some of the most menacing ones in the street. Upgrading your engine is a multi-step process, and there are multiple approaches you can take to get the improvements that you need. One of the most overlooked steps in the tuning process is engine preparation. What is this “preparation” and how is it done?
Engine Preparation Explained
Engine preparation is a process wherein the engine block is prepared for tuning. While it is not responsible for added horsepower, ensuring that the engine is sturdy enough to withstand the increased demands of increased engine outputs (thanks to tuning) is a must for improved durability and reliability under stress. Engine preparation is done in all levels of motorsport, and is considered as an essential step in tuning high-performance engines.
Inspecting the engine block
The first step in the engine preparation process is to inspect the engine block. All possible imperfections within the block and its parts such as the cylinder heads, camshafts, and the crank centerline are all assessed for potential structural flaws. The thickness of the block, especially in high-stress areas, is also checked. The block is also cleaned and polished to reduce internal friction for smoother engine performance. All engine parts are also checked to see if they are placed correctly.
Reinforcing the engine block
After a thorough evaluation of the engine block, steps are taken to strengthen it. All weak spots observed during inspection are reinforced. Parts of the engine block are replaced to include stronger (and possibly lighter) parts wherever possible. All bearings are evaluated and replaced where necessary for superior fit. Depending on the level of tuning, how the engine will be used, standards of reliability, and financial considerations, the level of reinforcement you can put into an engine block can vary.
