Competition Engine Development “CED”

A three day course which covers advanced-precision, full competition-level engine building techniques from a raw engine block to a running engine on the dyno.

!!!WARNING!!!
This course is way beyond “Blueprinting”.

This is a hands-on, instructor-led journey through the maze of items to be checked, measured and inspected during the engine assembly process, but with strong focus on the “Planning” phase of parts selection before the assembly ever begins.

This course is about the advancement of an engine’s performance by evaluating 3 main areas of “efficiency”

 Volumetric Efficiency, or the ability to move more air through the engine.  The components we choose must match the intended application and rpm range and we will discuss ways to evaluate our choices based on Dyno and race track results after the build.
 
Mechanical Efficiency, or the reduction in friction and drag which cause parasitic losses to the power created during the combustion cycle.  As we move parts and slide them together in the engine we create losses through friction, (which also generates more heat for our thermal efficiency considerations).  These losses are exponentially worse with more speed and as we continue to raise the RPM of our engine the parasitic losses due to drag can easily outpace the gains we’ve achieved from volumetric efficiency.  As we evaluate each component in the engine, we will consider the balance between its mass, stiffness and inertial effects on other engine components and try to find ways to maximize efficiency in this area by minimizing drag without sacrificing reliability.
 
Thermal Efficiency, or the ability to convert energy available in the fuel to Horsepower. In a standard engine, less than 30% of the heat we create during combustion becomes measured horsepower. The other 70% gets lost to the cooling system and out the exhaust pipe.  Anything we can do to shift these losses to our favor will result in more power. 
WHAT TO EXPECT DURING THE COURSE:
We will address issues related to each of these efficiency subjects over a 3 day period while we carefully assemble a high-rpm, drag-race competition engine.
 
 While we work our way through the engine assembly process, we will take many opportunities to understand the critical concept that we have a “series of dependent events” conspiring against us and 14484971_10157602758275441_4689657499584865976_nany change we affect in one component can have adverse effects on other systems or components.  (This is a cardinal principle of our philosophy and an exceptionally valuable lesson to be learned throughout the course).
 
We will have in-depth discussions combined with hands-on exercises designed to provoke students to think outside the normal accepted standards of engine building.
While building the engine we will explore ways to maximize airflow, increase thermal efficiency and reduce drag starting from a bare block and analyzing each and every component as we inspect and assemble it into the engine.  
 
We will begin by placing special emphasis on understanding the role of the oiling system, pinpointing losses from too much or too little pressure, windage loss prevention techniques and we’ll explore ways to minimize engine oil flow requirements in an effort to control pumping losses.
 
Next, we will explore the block surface finishes and discuss the logic behind why a particular measurement needs to be what they are.  
 
For example:  we will use a “Profilometer” to take measurements of cylinder bore surfaces (down to millionth’s of an inch) and determine the ability of those surfaces to retain the proper volume of oil to lubricate the piston and rings without holding too much and causing issues and we will discuss ways to fix those issues should they arise in your future projects.
 
We will also cover ways to accomplish all required block measurements and dimensional calculations in order to create a plan for reaching our power and reliability goals.
 
Once the bare block has been covered, we will perform (both in the classroom and engine shop) the measurement and documentation of all engine components and give special consideration to any modification to those parts before we assemble them.  
 
For example: in certain scenarios we may decide to reduce the diameter and or narrow our connecting rod bearings or camshaft bearings and we’ll discuss how and why to do so during the course.14595595_10157602757605441_8562786470321090868_n
As we begin to perform the assembly of the engine we will discuss engine fastener technology and theory and compare methods of ensuring our fasteners are up to the task we’ve selected them for.
 
We will discuss and display the effects of various piston shapes, profiles and ring packages and explain what the benefits of each type would be for a particular application, and we will look at the pros and cons of camshaft material and core diameter considerations along with lifter and rocker arm modifications available to increase strength and reduce mass.
 
Once we’ve assembled our short block we will perform the “diagnostic” phase of our build by accomplishing a combustion chamber and cylinder volume measurement called “CC’ing” the heads and block where we will calculate our actual compression ratio, and then degree the camshaft to check for proper installation.  
We will also discuss and display the practice of creating a mold of the combustion chamber for the purpose of building custom Pistons made to order exactly for our engine.
 
Finally, we will finish the assembly of the long block by installing our cylinder heads, checking our piston to valve clearance and explore valve train geometry, how to measure it, and how to correct problems that crop up while we also explore the methods for setting up and checking the cylinder heads and valves themselves.
 
Once the engine is completely finished and all measurements have been checked and documented we will install the engine on a Dyno and complete the pre-startup checklist and prime the oiling system.
 
When all systems are “GO” we will light it off and run the engine up to temperature before making some pulls at high rpm to measure its performance.  After an initial run-in we will remove the valve covers and check valve spring pressur14604835_10157602724295441_7057518691726570069_nes and valve lash before running a few follow up tests and perform  some final tune-up changes to achieve the best result.
 
Students will have an opportunity to take photos with their class engine and will receive a certificate of course completion before we wrap up and answer and final questions.
 
All in all, it will be an action-packed 3 day crash course and offer a peek inside what the pro’s do to “develop” a competition engine.

The popular Chevrolet LS V-8 will be used in the class, however, all of the information covered in this class can be applied to ANY engine you build.

Also students will have access to using the highest quality and most accurate assembly tools available and see why the investment in the correct tools will help you get the job done right the first time.    

Students will learn:

  • What needs to be measured
  • Where to measure the component
  • How to use measurement tools correctly
  • Proper documentation skills and procedures to catalog all measurements

Special emphasis will be placed on:

  • Finding and understanding problem areas
  • Understanding Min/Max Clearances and Tolerances for various applications
  • How to fix issues when they do crop up

Students will also learn:

  • Engine theory
  • Component identification
  • Assembly do’s and don’ts
  • Understanding Piston shapes for various engine types
  • Special techniques for N/A versus Forced Induction applications.

Students will inspect, measure and assemble an LS engine from a bare block and then install the engine on EFI University’s Mainline-Dynolog Engine Dyno and go through the engine break-in and EFI tuning process using the same techniques employed by top race teams!

This 3-day class is only offered at our state-of-the-art training facility in Lake Havasu, Arizona and is limited to 6 students per class for an excellent student to teacher ratio.

Just consider the peace of mind you can get from your engine projects for less than the cost of a single rebuild.

Don’t build another engine until you attend this course!

Limited to 4 Students Per Class

Tuition: $2995.00USD
