The first step in preparing an itemised engine specification is to get a clear picture of what the engine will be used for e.g. daily driver, street/strip, race only etc. Some people come to me with a very clear idea of what they want, or maybe there’s a certain look or style thatRead More

In Part 4  I discussed dynamic balancing theory, including an explanation of the terms used to describe the tolerances suitable for a typical high performance engine. The previous post finished off with the crankshaft (complete with crank gears) balanced well within the target tolerance ofRead More

Dynamically balancing the crankshaft assembly is an important part of any engine build. This article attempts to explain why. I’ll kick off with a little theory and then demonstrate by example, showing each step of the balancing process as applied to the crankshaft, flywheel, clutch andRead More

In Part 2 I explained my reasons and some of the theory behind the bore and stroke combination I’m using in Project 2110. In this instalment I’m going to cover the machine work required to physically accommodate an 82mm stroke crankshaft and big bore 90.5mm cylinders. As with theRead More

As outlined previously in Part 1 of this series, the aim of Project 2110 is to design and build an engine that delivers strong torque across a wide rpm range. Before discussing the pros and cons of various bore and stroke options, a quick discussion on TORQUE and how it relates to engineRead More

The first in a series of articles covering the theory and practice of building a high performance Type 1 2110cc engine. The engine will be fitted to a split screen bus and is being designed to deliver a good combination of power, torque, driveability and most importantly, reliability. Some ofRead More
