APR High Pressure Fuel Pump - 2.9T & 3.0T EA839 (New Pump)The APR High Pressure Fuel Pump (HPFP) increases maximum volume of fuel the HPFP can deliver by 37% over stock! In doing so, the direct injection fueling system is capable of satisfying fueling requirements set forth by high horsepower setups. This is accomplished by increasing the displacement of the pump using high quality components to exacting tolerances. On the B9 2. 9T we achieved an additional 37 AWHP and 50 AWFTLBS over our Stage 1 (E85) ECU

The APR High Pressure Fuel Pump (HPFP) increases maximum volume of fuel the HPFP can deliver by 37% over stock! In doing so, the direct injection fueling system is capable of satisfying fueling requirements set forth by high horsepower setups. This is accomplished by increasing the displacement of the pump using high quality components to exacting tolerances. On the B9 2.9T we achieved an additional 37 AWHP and 50 AWFTLBS over our Stage 1 (E85) ECU Upgrade by adding the pump and running our Stage 1+ (E85) ECU Upgrade! How the direct injection system works: A low pressure fuel pump (LPFP) in the fuel tank delivers fuel to the high pressure fuel pump (HPFP) at roughly 4 to 6 bar. Fuel pressure is then bumped up to a maximum of 200 bar, depending on factory parts, with the HPFP. Finally, high pressure fuel is delivered to the injectors, which spray directly into the cylinders. The problem: The volume of fuel the HPFP pump can displace is directly tied to the displacement of the pump (Internal bore size, and camshaft dictated stroke), and engine speed. The pump is driven off of a lobe on the camshaft. Larger turbocharger systems, and ethanol usage are capable of taxing this system, especially in the mid to lower RPM range where fuel volume is lower. The APR solution: We dramatically increase the volume of fuel the HPFP can displace at every RPM by increasing the displacement of the HPFP. This is accomplished by increasing the bore diameter of the pump's internal pressurizing cylinder. It's important to understand, despite the name, a HPFP upgrade is not necessary designed to increase the engine's fuel rail pressure. The primary goal is to increase the volume of fuel available, which will keep fuel pressure steady even in the most demanding of situations! High quality components and extreme tolerances: The HPFP internals must be machined to extreme tolerances and installed in a clean environment or the pump can easily fail. Dimensional tolerances on the APR HPFP are as tight as .00004" and geometric tolerances are as tight as .00005". The plunger and barrel are created from certified and heat-treated bearing-grade stainless steel and the plunger undergoes a special diamond like coating process for exceptional surfaces hardness and ultra-reliable operation. To prevent float associated with altering the plunger's mass, APR supplies each unit with a properly specified spring. All necessary internal seals are replaced. Internal testing: All APR HPFPs are assembled in house under strict assembly guidelines. Each pump is then tested on our test rig to ensure the pumps operate as designed. This step is important for several reasons. It's critical in determining if a pump has a failure from incorrect install, a leaking seal, or a bad solenoid. Secondly, a seized pump on the vehicle at startup can cause damage to the engine's camshaft. By testing each pump, we all but eliminate these possibility. Proven track record: APR pioneered HPFP upgrades in the early days of VAG direct injection engines. Soon after, APR became an OEM supplier of HPFP and GDI components to VAG for use in various race cars, racing series, project cars, and concept vehicles. The APR HPFP has been at the center of countless motorsport victories across the globe and has operated with a nearly perfect tract record since the program's motorsport backed inception in 2006. With tens of thousands of pumps sold, APR has a wealth of knowledge, and manufacturing expertise necessary to deliver a product that will and has stood the test of time. This kit includes a new rebuilt pump.

Excellent Handbook!
Format: Paperback
This is a great book for anyone from beginner to seasoned activist. Kazu Haga breaks down Kingian Nonviolence and other justice and healing modalities in a way that makes them very accessible to a wide array of readers. I plan to give this to several elder activists - and my 14 year old niece. Haga breaks down the Six Principles of Kingian Nonviolence, Restorative Justice/Practices (RP), separates & defines four types of conflict as well as other clarifying enumerations of large concepts. As an RP practitioner, I found his handling of restorative work to be excellent, and I found the Kingian principles revelatory and beautiful. Kingian Nonviolence dispels the myth that nonviolence is passivity "Nonviolence is not about what not to do. It is about what you are going to do", and has clear steps toward justice and conflict work that have proven efficacy. Haga's handling of nuance and contradiction is unique and powerful, as well as his personal approach to understanding alternate perspectives (listening to right wing radio on regular basis - with an open mind -for instance). More than one thing can be true at the same time, we can expand to hold contradiction, and still seek accountability and healing. The clarity of why shaming and punishment doesn't work for preventing future harm, or healing harm that has occurred is present not only in the concepts in the book, but his personal experience via years of offering trainings in prisons. There is still a lot of resistance to RP and nonviolent approaches to harm - especially in Law Enforcement and Corrections, and I think the accessibility and clarity in this book are useful to help naysayers possibly see the light of why these healing and justice practices ultimately protect us all.

This is the one
Format: Paperback
If you read one book this year about how to deal with conflict, this is the one. His language is crisp, his examples simple to understand, his reasoning is easy to follow. Best of all, he interprets Dr. King's Philosophy of Nonviolence through his own, hard-won experience with organizing in Oakland, CA, Occupy Wall Street and myriad other struggles. All that experience has taught him that Dr. King was right to focus on relationship building. Kazu asks the hard questions, toughs out the answers, learns from myriad mistakes and shares his hard-won lessons with us. He also references some great resources. I gave this book 5 stars. Normally I would have awarded 4 stars, because there are some typos sprinkled throughout the book. However, I added back that star because the book is so very well-written, absolutely authentic to the Kingian Nonviolence curriculum, and urgently useful NOW. Kingian Nonviolence (not non-violence) is more useful and effective than any other strategy, for the long-term, and often for the short term as well. Let's build this world of Beloved Community. Thank you Kazu, Dr. Lafayette, and Dr. King, for giving us a head start.

The Inner Game of World Changing
Format: Kindle
This book bridges the gap between activism and spirituality, making the argument that the world will never change for the better in a lasting way without both working together. Yes, the systems of injustice must be dismantled, but it will be impossible to build new systems that work for all without the inner foundations spelled out in this book. Yes, we need to love one another, but we also need to deal with the material realities of injustice and oppression. Without the principles laid out in this book, we are left with a toxic culture of shaming and ineffectual anger on the side of the activists and a loving but disconnected-from-reality culture on the side of the spiritual while the violence-fueled industrial-growth complex goes on wreaking its destruction. If you despair of things ever changing for the better, read this book. It's THE way forward.
