Usually there isn’t much you can do to increase the diameter of the cylinder liners without some help of a machine shop. The cylinder liners or sleeves make up the walls of the combustion chamber. The greater the area for compression the more fuel burned and thus more horsepower. ALTER THE CYLINDER LINERSīoring out the cylinder liners is a common way to increase horsepower. Common lighter but less durable part swaps include the flywheel, flywheel housing, camshaft and ancillary fuel, water and oil pumps. Aluminum blocks, commonly used in automotive engines, are much more prone to cracking. Using aluminum versus cast iron heads and blocks will reduce the weight of the engine but also decrease the durability of the core. Modifying an engine to make it lighter without sacrificing compression will produce a more efficient distribution of energy to the crankshaft and thus higher horsepower. Overall, reducing the weight of the engine will increase the horsepower. That being said the changes to the cylinder liners go hand in hand with oversized or undersized pistons.

Your diesel engine is engineered for a certain piston configuration based on the engine serial number and deviation from OEM spec could damage your engine if not modified properly. You can alter the weight of the pistons by using less dense material such as a lighter aluminum composite but you will always run the risk of pistons breaking. Clearances are usually very tight as far as piston length goes. Most likely you are not going to be able to alter the stroke length (up down cycle of the piston). ALTER THE STROKE LENGTH AND ENGINE WEIGHT There are only five mechanical ways to increase horsepower out of a diesel engine: Increase Pressure in the Combustion Chamber, Alter the Stroke Length, Alter the Cylinder Liners, Increase the Power Strokes (RPM) and Decrease Friction.

MACHINE SHOP HORSEPOWER MODIFICATIONSīefore we dive into the various fun ways on the aftermarket side on how to increase horsepower let’s first look at the physics of what is structurally possible and what is not possible on an existing diesel engine. This article will address what is capable by changing the hard internal components of the engine as well as 13 common aftermarket modifications to add more power to a diesel engine.
We want to go fast and we want it now! The good news is that there are plenty of ways to add more power to a diesel engine that don’t require expensive modifications.
The number one question with any engine, whether it be gas or diesel, is how do I get more horsepower? Raw power is the name of the game.
