Speed Trapp Consulting KnowledgeShare

Speed Trapp Consulting is not just about selling turbochargers, but getting people to become more informed when it comes to turbocharging.  Over the years, especially with social media becoming an ever-increasing source of information in our world, some knowledge can get lost or confused as to what one should or should not do when it comes to preparing for turbocharging. Whether the project be getting the right turbocharger as an active replacement for a unit that has been damaged, or a 2500hp Drag Race-only project, the essential components onto which they operate haven't changed for about the last 70 years. 
 
But that does not mean that people are left to not understanding the myths vs. facts of how turbocharging is to be best utilized. It is understanable that in some ways, working turbochargers is as much art as it is science, but as new developments have come into place, it is much more important to understand the subtle differences on how these units work, so that the client can have an enjoyable experience for years to come.
 
Some of the sources of these articles are written by STC for the benefit of its customers.  Others have been written by citation-noted reliable sources; that means that the information didn't just come from anyone online. In the event that we don't have the particlar time and resources to create an entire new article of information as part of the knowledge base, we will cite the source of the information that you would be reading. If there are any questions, please feel free to contact us.  All files are either in .JPG, .TIFF, or .PDF format
 
In addition, we do have consultation services for much more in-depth explanation and advisory consult for your particular project. If this is an ongoing project in which we can be able to help in a more substantive manner, please e-mail at consult@speedtrappconsulting.com in which we can determine the right path for you. There is a rate of our consultatation (We must pay the bills) and that can be found on our Consultation section of the website.

Turbochargers - Run best with Water!

This Garrett White Paper delves into the reasons for their integration into the system and shows graphic examples of what can happen when they are not implemented. Whether the turbocharger's Center Section contains Journal Bearings or Steel Ball-Bearrings, the key to durability and longevity is to run water lines whenever possible.

The white paper also describes the optimal method to hook up these water lines, but we feel that this information can be conflicting and confusing with turbocharger Center Section orientation, so we believe it is not as relevant.

Burst & Containment of Turbine Housings

Wheel burst can be a serious safety concern when a turbo is pushed to its limits. This Garrett® white paper explains wheel burst: what it is and how it can happen, the amount of energy released by a burst, and how each and every Garrett® OE and aftermarket turbocharger for sale to the public is designed and qualified to safely contain the fragments of a bursting wheel.

Intercooler Types - Size alone is not what matters most

This article gives a quick description as to the types of Intercoolers that are most popular with both sport compact and larger displacement gasoline-powered vehicles. It was co-authored by The Shodan of Honda-Tech but references photo examples and information by Evan Griffey of Turbo Magazine written in April 2003 with commentary by Johnny Wang of Spearco intercoolers

Borg-Warner "Earth Friendly Racing" (EFR) Turbocharger Technical Articles

Borg-Warner almost 10 years ago developed and released their Earth Friendly Racing (EFR) turbocharger designs to the public, orginially using Full-Race as its sole distributing member. With new distribution infrastructure and utility now in place, STC believes that understanding the history of this particularly unique conceptualization and implementation be shown. From the Borg-Warner / 3K line forward, this small documetary details how the EFR line was created

Mitsubishi Turbocharger Nomenclature

It is normal for those that use Original Equipment Manufacture (OEM) factory turbochargers be confused as to which name designation belongs with an engine application. This is especially true of that same OEM turbo is going to be used on an engine for a retrofit application that was never designed to be there. In addition, although Japanese Companies like GReddy / Trust, and Apex Integration no longer sells turbochargers in the same volumes as they had before 2006 to the public, their units are still in use by users and race teams today, however, they no longer have the data to which to compare their unit to more utilized units of today.

With terms like "T3/T4" and "TD04", "TE04", "TD05", "VF3X", "RH6" and "16G", being thrown around on forums and other media incorrectly, we thought it would behove the user to understand specifically where these Mitsubishi Heavy Industries (MHI) and Ishikawajima-Harima Heavy Industries Co., Ltd. (IHI) naming conventions originated. Below is an article that explains these particular origins.  Please note that neither the GTX nor EFR line are mention in this brief.

Turbocharger Troubleshooting

Deciding when it's time to rebuild or replace a turbocharger can be confusing, and misleading at times. Some symptoms of issues within the turbocharger can be easy to spot, while others can give a false reading, leading to another problem within the engine that the turbocharger is simply experiencing.  This decision can be wasteful and expensive if the wrong diagnosis isn't determined.  Below is a quick-reference troubleshooting chart that can easily help rule out issues that may give a false reading, and help determine whether or not repair, or even replacement is the right course of action.  Either way, the best, first response is to stop driving the vehicle.

Titles in Red font are the symptoms that the turbo was/is exhibiting, while the titles in Black font are possible causes

Garrett Turbocharger Installation Card

This is the Installation Card that should come with all Garrett and STC-Garrett /Honeywell Turbo Technologies turbochargers. If you do not see this card in your Garrett turbocharger package, please look here to find out the specifications (marked as "in-lbs") and convert to ft-lbs.  Typically "hand wrench tight" will suffice, but please be sure to use proper equipment when installing. When in doubt, let a professional install your turbocharger. STC is not responsible for improper installation.

Turbocharger Installation Checklist

We recently created a great checklist for those that receive a new turbocharger and want to ensure that installation is proper before starting an automotive or diesel engine.  This is essential in ensuring that the turbocharger gets proper oil fed to the oil channels the second that the turbine shaft rotates, to keep the turbocharger running smoothly.  Print this check list out if necessary, as a final walk-through.

Turbocharger Installation Checklist

Turbonetics also created a Guide in 2004 that contains information that pertains to older Turbonetics and Current Journal Bearing and Dual Ball-Bearing Garrett Turbochargers, including the GT(X) Generation I and Generation II Series. It may not specifically call to specific Garrett nomenclature and series names, but they still retain all of the essential information that older Turbonetics (pre-2010 models) and current STC-Garrett Journal Bearing models.

Technical Documentation On Emerging & Disruptive Technologies

This section is dedicated to those automotive areas of forced induction that put a focus on engine tuning, mapping, and other protocols that require the use of 2012+ vehicles utilizing OBD (On-Board Diagnostic) and (Control-Area Network) CAN-BUS technology which is a vehicle bus standard designed to allow electronic control units and devices to communicate with each other in applications without a "Main" computer or ECU.

This is a newer area for STC, as we are now in active engagements with law firms, engineering facilities, and education centers to which we educate, promote, and consult with businesses and entities whose focus are on emerging and distruptive technologies in the automotive industry.  This section is dedicated to more dynamic fields of forced-induction from both the production and aftermarket standpoints.

OBD & CAN-BUS White Papers

Ever want to know what hardware and software it takes in order to utilze these systems? These articles, white-papers and noted readings are part of our continuing research & development on how to legally manipulate, test, and work with these emerging systems in today's vehicles, while still retaining the demand and utility of the aftermarket community.

CAN-BUS Explained in a Nutshell

Kiril Mucevski created a fantastic white paper as to what CAN-BUS really is, and how it is differentiated from a traditional vehicle wiring harness. This white paper explains the HS-CAN and MS-CAN voltages that are utilized in these systems to keep them efficiently connected to their individual ECM modules while keeping information flowing between the modules strong.
