HIGH PERFORMANCE TURBO DOWNPIPES BY HPA
Maximizing engine performance starts with engine heat management. Turbo charged applications generate extreme amount of surface heat at the turbo charger that radiates directly into the aluminum head reducing the engine ECU's ability to advance ignition and fueling maps due to detonation. Besides strict global emissions standards resulting in restrictive catalytic converters being installed, oem engineers must factor global restrictions on minimum clearances for front impact crash test results when packaging and designing the factory turbo downpipes.
Each HPA downpipe application is designed around emissions compliance requirements, thermal radiation/contact surface clearances and engine ecu software framework. The calibrators drive the hardware demands to ensure that the dimensions and catalytic converter requirements are calibrated within the spectrum of the ecu's capabilities. The goal is to reduce the heat at the mounting surface of the turbocharger to the aluminum head. When the balance of heat reduction has been realized, the calibrators can create a fuel and ignition mapping that will ensure that the tailpipe gases are clean and the boost levels can be raised. Heat is the enemy of HP and even your stock mapping will benefit form a more fluid design of exhaust gas discharge.
The average OEM 63mm downpipe diameter coupled with a restrictive catalytic converter and varying angles don't allow for ideal flow specifications and result in higher back pressure at the turbo forcing it to work harder and generate excessive heat.
HPA's resulting 3" downpipe is a fabrication assembly designed around functionality and durability and proudly manufactured in Canada. .063wall T304L stainless mandrel tubing is precision tig welded and Argon back purged for an ultra clean look on the exterior and a perfect clean weld on the interior. Our CNC formed hanger and laser cut flanges mate this assembly to the chassis and will withstand the thermal conditions the turbo will generate. Our flex couplings feature an internal stainless steel interlock liner that facilitates smooth flow of high temperature exhaust gases.
HPA EA888 Gen 1 and 2 street downpipes come standard with our 100C high flow cats while the new MQB GTI and Golf R come standard with our 300 cell metal cat, the same quality of cats used on all HPA twin turbo high performance vehicles.

A must read for any pastor or spiritual leader
Format: Paperback
This book is profoundly insightful and easy to read and understand. It is not heavily theological (and does not need to be). It is practical. I have purchased an additional copy to give my pastor for his birthday. If he has already read it, he can pass it on. EVERY pastor needs to read this and practice these tips, which many do not receive in seminary. THIS is the type of pastor I want and need (and my pastor does embody much of what Peterson describes). I think pastors should read this every year or two to reassess their progress toward keeping these goals always in mind and in practice as much as possible.

A still timely writing for all pastors
Format: Paperback
Although first published 25 years ago, Peterson addresses a matter that is still timely, the need for all pastors to commit themselves to prayer, reading scripture and spiritual direction. These, Peterson asserts, are an essential foundation for all other aspects of ministry. Peterson's premise, that many pastors have abdicated their primary calling to these three practices, is still very relavent to the current state of pastoral ministry. Its content will be useful for new and veteran pastors alike.

Transformative if you are willing.
Format: Kindle
The triangle of pastoral ministry
- Scripture - Prayer - Spiritual Direction is reckoned as sever lack in our pastoral lives. Peterson is a needed sage in the realm of modern evangelicalism.

A Personally Challengiing Read
Don’t expect Rosaria Butterfield to coddle sin. She acknowledges the Biblical truth that we are at war with it. It is evil. Lies are rampant with it. The Bible’s solution is to kill it, nailing it to the cross of Christ. If we don’t, it will do great and lasting harm. That is the background premise of this book.
This book is for believers in Jesus Christ, especially those who identify as Evangelicals. Others may benefit by reading its pages, but I suspect that most of them will not be able to persevere through it because today’s culture is just not willing to sit through this much proclamation of Bible truth. They will react, not respond. Believers will be convicted, encouraged, and edified.
Butterfield’s style is plain, but today’s culture requires her to address and to use terminology that may be challenging to many readers. It was for me. Add a level of abstraction for some challenging spiritual truths. Add the fact that she is an intellectual dealing with cultural and theological subjects. It is mostly college level reading, except for the story parts.
Butterfield has credentials. A professor of English at Syracuse University, she was ten years in the Lesbian community with a mate. She was found by Christ, began to grow in Him, was discipled by faithful church women, met a wonderful man, was married to him--a Presbyterian pastor—became a mother, and began to minister to college students from a Christian perspective. She tells some of her story and the stories of others in the pages of the book. It is fascinating reading.
The book is organized around the five lies that Butterfield has chosen to expose, with two to four chapters dealing with each. She acknowledges that there are others that could be exposed as well. The last one, about our culture's attitude toward modesty, was the most surprising to me.
The book also has a Foreword by Kevin DeYoung, a Preface, and an Introduction. Don’t skip them. The Foreword is nothing short of a good sermon that should be shared in every church in America. In the Preface Butterfield spills the beans, revealing exactly where she stands on key topics and to whom she is addressing this volume. The Introduction is engaging and lengthy and pretty much summarizes the rest of the book.
Along the way Butterfield deals with homosexuality, changing gender, male leadership in the home and in church, the bedrock importance of repentance, progressive sanctification, intersectionality, “gay Christianity” (Side A and Side B), feelings and truth, empathy and sympathy, submission of the wife, feminism, inerrancy, envy and biblical contentment, suffering, modesty and exhibitionism, and even worship.
She quotes scripture, sometimes at length, and she gives copious Bible references. She also has footnotes, some of which are as interesting as the text. She names and uses or responds to contemporary authors on the topics at hand.
She gives solid directions for those dealing with contemporary issues. She also has suggestions for dealing with family members beset by these matters including a question-and-answer section. Page 301.
I recommend this book for all Christian leaders and for believers who want to understand contemporary challenges for the church from our modern culture.
