Overview

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. OEM Components: Critical to the design of the APR HPFP is the use of only genuine Hitachi components, made in Germany, which consists of sensors, pump bodies, and other critical components that must operate with OEM levels of reliability. All APR components are made in the USA using medical grade precision machinery that goes well beyond the tolerances capabilities found at automotive engineering companies.

A Clear Concise Precis of a Complex Historical Era
Format: Paperback
R.W. Southern's book titled WESTERN SOCIETY AND THE CHURCH IN THE MIDDLE AGES is a readable account of the Medieval Catholic Church from c 750 to c. 1450. Southern concisely explained the achievements, successes, and failures. According to Southern, the achievements and successes far outweighed the failures and wrong doing. Southern's book began with the special relationship between the new "barbarian" secular rulers and the Catholic clergy especially the monks and bishops. The fact that most secular rulers were not literate especially in the use of Latin, they relied on learned Catholic clergy. The Catholic clergy became crucial and both they and the secular rulers relied on each other. While Charlemagne (768-814)had a revered status as the defender of the Latin West, Southern mentioned his reliance on Catholic clergy. Charlemagne could read,but he never learned to write. He was aware of his own deficiencies and started the Palace School at Aachen where, among others, Alcuin (735-804) and other learned men expanded learning at a time called the Carolingian Renaissance. What readers should appreciate is that without Catholic clergy and monks, learning would have disappeared in Western Europe. Southern was very clear about this. The Medieval Catholic authorities faced other challenges. Long simmering feuds existed between the Byzantine Greek Orthodox Church authorities and the Latin Roman Catholic authorities. During the eighth century and again in 1054,the official reasons for tensions were the use of icons (The Iconoclastic Controversy) and the status of the Pope. As Southern wrote, these tensions were a cover for the disputes between the Italians and Byzantine Greeks over Byzantine control of parts of Italy. What the Greek Orthodox and Byzantine authorities did not want to realize was that the Latin West including the Popes were their only salvation vs. the Islamic Seljuk Turks especially after the Byzantine defeat at Manzikurt in 1071. In 1422, Pope Martin V (1417-1471)reminded the Byzantine religious and secular rulers how much they relied on the Latin West. In other words, Pope Martin V demanded concessions if the Byzantines expected help vs. the Turks. Because of the lang standing traditions the Byzantines had, they refused to face their doom which occurred in 1453. Southern's description of this dilemma was well presented. An achievement that Southern emphasized was the development of Canon Law. Increased trade, urbanization, and political power led to conflicts between secular rulers and Catholic authorities. Some of the Medieval Popes were known as "The Lawyer Popes" such as Pope Alexander III (1159-1181), especially Pope Innocent III (1198-1216), and Pope Pope Gregory IX (1227-1241). While the Popes could and sometimes used excommunication and interdict to intimidate secular rivals, the problem became acute because of too much reliance on these spiritual weapons. Not only did the Popes exert power and influence, the Catholic bishops also had considerable influence. The Cathoic bishoporics existed long befor the monastic orders and the friars. The ideal for bishops was Pope Gregory's (590-604)work titled PASTORAL CARE. Due to the bishops' position of power and status, many became too involved with poltical situations that mitigated Pope Gregory I's ideal. Bishops had to enforce discipline, show wisdom, and administer effectively. Southern mentioned some of the bishops who were effective and some who were inept. For example Bishop Odo Riguad (1247-1276) was "firm but fair." He was lenient for qualifications for those who wanted to enter Holy Orders and was reasonable, in fact kind, re reconcilation. Yet, he expected those under his authority to comply with their priestly duties. On the other hand, John Peckham who was the Archbishop of Canterbury (1279-1292)was obstinate, incompetent, and not capable for the position. After the Papal Election Decree in 1059 and the Investature Controversy, the Popes wanted the local clergy to decide on the appointment of bishops. Southern told readers that even a Pope as powerful as Pope Innocent III (1198-1216)preferred local selection. While Popes could intervene if no decision could be reached, they preferred not to impose what Southern called "The Royal Road." While the bishoporics existed prior to the monastic orders and friars, the latter groups were also crucial to the Catholic Church and the Latin West. The dominant orders included the Benedictines started by St. Benedict (480-544) whose Benedictine Rule was the standard until c. 1050. The work of the monastic orders re learning can never be underestimated especially since they wrote and hand copied books including the Bible long before the invention of the printing press. Their influnce was such that a Beneditine was made Pope-Pope Gregory I (590-604). Other orders such as the Cistertians and Augustinians later developed separate from the Benedictines. The best known of the Cistertians was St. Bernard of Clairvaux (1090-1153)whose rhetoric and conservative views were a check on unbridled enthusiams. The friars were orders of men and women who left the cloister to appeal to the masses. St. Dominic (1170-1221) started the Order of Preachers or Dominicans as a learned society of men and woman to combat heresy. The Friars Minor (the Franciscans) were started by St. Francis of Assissi (1182-1226),and these men and woman started as an order to help the poorest of the poor. Southern could have mentioned that St. Francis helped those even God ignored. The Dominicans and Franciscans became dominant teachers in Catholic universities and revived interest in Ancient Greek thought. These men and women also made signficant contributions re science and mathematics. A major reason for the creation of the friars was the gradual increase of urbanization. As Southern reminded readers, without towns, there would have been no friars. Without universities, the friars would never have been great. By the middle of the 14th. century (the 1300s), the Scholastic achievements faded because of the trivial debates. This led to a revival of Catholic mysticism such as Thomas a Kempis' (1380-1471)who wrote IMITATION OF CHRIST and later St. Ignatius Loyola's (1491-1556) SPIRITUAL EXERCISES. As Southern warned did such mysticism lead to false piety? Southern did an effective job re Medieval Catholic Church History. He could have emphasized the work of some of the giant intellects such as St. Albertus Magnus (1193-1280) and St. Thomas Aquinas (1225-1274). Southern's treatment of Canon Law was later enhanced by Berman's book titled LAW AND REVOLUTION. Students of Church History will benefit from Southern's book. It is clear, and complexities are carefully explained. The list of Popes at the end of the book can help readers to keep track of the "players." James E. Egolf November 5, 2013

From the Bones of Peter
Format: Paperback
A brief forward to this work is in order. R.W. Southern stands among England's finest historical scholars of the twentieth century and was knighted by the Queen in 1975. The publisher, Penguin, has worked to bring the best of the humanities to an inquisitive public for almost a century. Southern's medieval survey is thus an eminently readable text buttressed by a profound grasp of both trends and minutiae. Our work at hand is one of seven independent works in Penguin's history of the Church series. Southern's contribution was first published in 1970 and updated in 1990. Historians are bringing more interdisciplinary tools to the study of medieval history, from climate to demographics to agriculture. Southern is the product of an earlier and more basic methodology, where the nexus of Church and Society stood as the interpretive key to an understanding of the times. I first read "Western Society and the Church" shortly after its original release in 1970. Reading it again in 2014 impressed upon me how compatible Southern's comprehensive overview stands with what we now know in greater detail about mystical movements, cold winters, trade, exploration, and plague, among other factors. Despite the wide sweep of his narrative, Southern's conclusions are drawn from meticulous examination of records, with useful numerical charts interspersed from time to time. Southern treats of the years 800-1500 CE and the provenance of the Roman Catholic Church in that era. The title's phrasing of "Western Society and the Church" is a pregnant one. The organism of the Church and western society as a whole shared a common cosmology or world vision. Medieval man did indeed understand himself to be living in a "Middle Age" between the time of Christ's first and second coming. However, Southern's overview provides many instances where the major organs of the Church and western society were hardly of one mind, either. Not surprisingly Southern devotes considerable attention to the changing Petrine ministry, which in 800 was not enjoying its finest hour. Besieged by Islam and other foreign peoples, belittled by Eastern Christianity from Constantinople, and its own house in disarray, Rome somehow maintained a religious and psychological hold in the popular mind. As reliquary of the bones of Peter, Rome and its successive bishops never entirely lost hold of mystery and supremacy in the early dark medieval era. In popular thought at the time, the pope was a living vicar of Peter. "Though men came to Rome in the first place to visit the (bones of the) Apostle, they prostrated themselves before the pope." (95) What would maintain Church order through dark times, Southern implies, was an inner sense among men of the times that God's order (and wrath) was mediated by the Church. Fractiousness between clergy and laity was common, but fear of damnation trumped all. Only the most cynical of men would knowingly dismiss hell fire And thus the Vicar of Peter became the Vicar of Christ. It did not hurt the cause that shrewd popes buttressed their positions with questionable emphases upon more ancient secular entitlements dating to the times of the Constantinian/Christian empire of the West. The heritage of Charlemagne and the forgery of the "Donation of Constantine" played their parts, but the permanent breech with the East may have been a deciding factor as well. Pontiffs such as Gregory VII came to understand their office as specific, detailed, and immediate. To speak anachronistically, popes became managers of a far flung bureaucracy of order and sanctification in what was now a Western European Roman Catholic venture. By 1100 there was plenty for popes to do. The relationship between pastoral appointments (bishops and abbots, for example) and the attendant financial compensation became quite complex. The papal office became official arbiter over disputes between various parties, to the degree that the majority of high medieval popes were drawn from the legal profession. Southern describes a medieval Church of prelates, scribes and lawyers crisscrossing Western Europe in the name of the Pope with portfolios of litigation and judgment. It does not miss the author’s attention that the papacy was also the greatest broker of spiritual reward and punishment, specifically its powers of excommunication and redemption, the latter becoming a major target of reformers at the end of the era. Southern contends that religious orders extended major spiritual and practical influence throughout the Middle Ages. In 800 the Benedictine Order, whose legacy would include spiritual efficacy, scholarship, good order, and physical enhancement of the environment, was at its apex. Southern proceeds to outline in some detail how the inevitable decline of fervor in a predominant order of the day would inspire the development of a new order to address developing contemporary concerns. As successors of the Benedictines, Southern identifies the Augustinians, the first medieval religious movement to embrace a generic rule derived directly from the Gospels as well as rigorous and moderate variants of daily life style. The next was the Cistercians, who sought to return to the letter and spirit of St. Benedict's rule. Their quest for purity and escape from the world led them to flee to the outer edges of Western Europe and consequently to develop these lands, a major social contribution. Southern sees the Franciscan and Dominican moments of the thirteenth century respectively as the Cistercian and Augustinian reforms for this later era of European society. Southern's penultimate chapters is devoted to what he called he called the fringe orders; today we would think of these in part as the Beguines and the multitude of spontaneous mystical and devotional movements associated with the fourteenth and fifteenth centuries. His final chapter, "A Confusion of Tongues," continues his account of spiritual diversification leading to early Protestant thought and practice. The tenor of this book is what one would expect of the relaxed scholar/gentleman unfolding his description of this age with a profound but understandable style. He shares a lifetime of scholarship in an inviting way to those entering the Middle Ages for the first time.

Excellent treatment of a narrow subject: how society shaped the church
Format: Paperback
This book is not a comprehensive overview of the church from 700-1500, nor is it a narrative treatment or an introduction. This book is highly selective, focusing on one central theme. Its strengths are in its organization and in the examples it gives to illustrate its theme. These examples are concrete, vivid and use quotations from original documents to excellent effect. The theme of the book is how society shaped the church. Southern examines the main institutions of the church -- the papacy, bishops, religious orders and fringe orders -- and shows how the needs and interests of society molded each. Perhaps having written on 1000-1200 in other books, for me, the strongest insights Southern makes here are on the periods 750-1000 and 1200-1500. Insights that particularly struck me: the importance of magic from 750-1000; the evolution of bishops, from supporting local rulers to supporting the pope; the importance of the Augustinian canons in the twelfth century, seeing them as one end of a pole, with the Cistercians on the other end and the Benedictines in the middle; the role of Franciscans and Dominicans in supporting scholars in the thirteenth century; and the fringe orders -- the book has one of the best treatments of the Brethren of the Common Life from the fourteenth century that I have come across. The book is highly selective. There is no treatment in this book on intellectual life (the "new learning") or artistic life, nor is there much on the heresies of the period or popular religion (the "new piety"). What the book does select to treat, it does so in a deep, highly readable, substantial way. One will definitely come away with how the demands of society molded the church. Highly recommended!!

Wonderful book, but not a general reference on the subject & period
Format: Paperback
Southern's powerful study of the organizational and administrative structures of the medieval church is a wonderful antidote for the popular view of the Middle Ages as a long period of almost continual chaos between the Fall of the Roman Empire and the Renaissance (i.e. the "Dark Ages"). Southern does a fantastically good job of explaining and illustrating the central truth of the Church in the Middle Ages, i.e. that the Church was identical with society to an extent that had never been true before and has never been true since. That said, Southern's disciplined approach is often too much of a good thing and there are a number of topics which one would expect to take pride of place in a typical narrative history of the subject and period that Southern touches on only obliquely and insofar as they are relevant to his primary topic: those neglected stories include the long papal/imperial struggle (Guelps & Ghibellines), the Crusades, the Black Death, etc.. Southern also has a puzzling and sometimes maddening tendency to couch the discussion in terms of implications, roles and epithets instead of being explicit and just naming names. E.g. in the context of the discussion of the fall of Constantinople, Mehmed II is mentioned äs "the conqueror", but not by name; that a pope visited Constantinople in 710 for the first time and last time in premodern history is noted, but the pope is not named (it was Constantine); some of consequences of the "Donation of Constantine" are implied fairly early in the book, but it is not explitly named (and then, to add to the reader's irritation, discussed later as if the topic had already been explitly introduced). These are all characteristic slips of an expert used to addressing other experts in his field attempting in this instance to write a more or less introductory text. They are understandable slips, but they take their toll. The book is generally excellent & well worth reading and it is hard to imagine a better introduction to the topics it does cover, but unfortunately, and unlike Chadwick's initial volume in this series, it does not serve well as a general reference on the history of the Medieval Church.
