- Turbo modification done to your OEM turbo to keep that stock look but flow 30% more **2-3 week turnaround**
- Ready to step up to the next level on your Pro XP and gain some serious power? Up to 320-330 crank horsepower! This complete turbo modification is just what you need for up to 28-29 PSI of boost! This is NOT just a simple billet wheel turbo mod, we are doing it all! We start off by modifying the compressor housing to accept the much larger, billet compressor wheel that will move some serious air. This gains turbo efficiency to push more air per RPM of the turbo. Boost temps will skyrocket quickly on the factory turbo, where as with our mod, they will be much lower... even at boost temps over 25 pounds! Now that we are moving air on the intake side, we need to get that air out. Our mod includes a bored out exhaust housing with a high flow exhaust turbine to create less back pressure and heat buildup in the motor. Heat buildup on the exhaust side is another HUGE issue with the factory turbo. What's essentially happening is you are running out of exhaust flow, and that makes more power very hard to produce. With this high flow turbine, we can increase boost and see a healthy increase in horsepower with our tuning on pump gas and race fuel. The factory wastegate is also a big problem as it's very weak, and as time goes on the spring only gets weaker. Building boost with a wimpy wastegate can produce varied results, hot temps, and turbo overheating. We install a high pressure billet wastegate actuator complete with a new bracket. This wastegate has extremely consistent results, will hold a huge amount of boost, and is a key component in this turbo mod working so well. Each turbo is fully blueprinted and balanced with new bearings from a professional turbocharger manufacturer.
- Thinking of another turbo mod? Many of our competitors offer an inferior mod, and do not offer the advanced tuning we do. Many use stock wastegates, do not bore the compressor housing, or do not modify the exhaust turbine. These are all huge reasons why our turbo mod works well. Tuning changes are drastic for modifications like this, and many others do not have the correct tuning knowledge to pair with such mod.
- Stock like drivability!
- On our dyno we saw 261 RWHP @28-29 PSI on 110 octane, and 267rwhp on E85 with some serious top end pull. That's a calculated 320-330 crank horsepower, +110rwhp or +140-150hp gains over factory!
- Keep in mind our dyno shows a little less than some of the dream-o-meters out there, and this package will normally out run similar HP vehicles, especially with our knowledge of the entire package of clutching, tuning and hard parts that work together properly.
- Big gains in low end performance and crazy high end gains on longer pulls (this mod does not fade off anywhere near as much as the factory setup)
- Lower EGT's (Exhaust temps) due to higher exhaust flow
- Lower intake temps before and after the intercooler per PSI of boost
- All tunes for this modification require our 1200cc injectors
- Requires AA custom tunes built specifically for this turbo mod
- **** RUNNING OVER 25-26PSI (LEVEL 5 or 6) REQUIRES A BILLET CRANK***** You can test the waters with the OEM crank, but most likely you will have issues. Most would pair this turbo mod with a built motor with: Brian Crower Billet Crankshaft, Carillo Rods, CP Pistons, custom age ARP head studs. A fire ring cylinder or K&T big bore cylinder are great options as well. Cylinder head porting, oversize exhaust valves and AA custom ground camshafts are also good modifications to add slightly more power.
- Running level 4 or higher requires all of our bolt on modifications, but our dual catch can setup. Our intake/catch can will NOT work for this setup as the vacuum is too high and will draw oil out. Requires plugs gapped to .020"
- All tunes were developed by one of the most experienced RZR turbo tuners, and tuned to maximum power for that fuel. Our dyno normally reads a bit low compared to some, so keep that in mind.... our stuff normally outruns the competition with the same HP level. -Mike
- We skip level 1
- The level 2 tune built for this mod is about the same hp as the OEM turbo level 2, with around 5hp more from the increased turbo exhaust flow. No real gains were found, the tunes are simply setup for the larger turbo/higher pressure WG crack pressure. Great drivability and decent fuel economy. You will see cooler intake temps with the turbo mod tune vs. the OEM pro turbo.
- The level 3 turbo upgrade tune is built for 91-93 octane. This tune produces around 7-9rwhp more than the OEM tune due to the higher exhaust flow. It's an 18-19.5psi tune and produces 182-185rwhp or 230 crank hp. You will see cooler intake temps with the turbo mod tune vs. the OEM pro turbo.
- The Level 4 turbo upgrade tune is for 98-100 octane fuel, and will run fine on octane higher than 100 as well. This will produce 220-225 RWHP (calculated 270-280 crank hp) at 23-24 PSI and hauls the mail! Most will mix race fuel with pump fuel to get the 100 octane which is what we recommend. A can of VP Octanium or Boostane to your tank will also work with this tune. This gains you roughly 20rwhp over the OEM turbo level 4. This tune is pushing it on the OEM crank, but in most cases will run on an OEM motor with the head bolts tightened to 85ft-lbs, or head studs installed. It will be safer to run on a built motor.
- The Level 5 turbo upgrade tune is for 110 octane fuel and simply drops the hammer! You'll have everyone wondering what is done to your RZR with this bad ass tune. The standard tune is 26-27psi for all day running around 245rwhp(290-300 crank), BUT we have the RACE tune which pushes a huge 28-29 PSI of boost that comes on HARD. This RACE tune produces 261+ RWHP (calculated 310-320 crank horsepower) on our dyno. We normally run this tune on 110 leaded fuel. Leaded fuel is harder on O2 sensors but we have not had much of an issue. We would suggest picking up another O2 sensor if running this tune, or you can run MS109 unleaded fuel.
- The Level 6 E-85 turbo upgrade tune is simply unbelievable. Very similar to the 110 tune power with both the standard 26-27psi tune and the higher boost RACE tune. The difference is this tune runs on cheap corn fuel, or expensive VP corn fuel! This fuel makes the motor run cooler and it absolutely loves it. The only downfall is you go through more fuel, and push more fuel into the crankcase, and into the catch can(necessary mod). If using pump E-85, make sure you are between 70-85% ethanol for this tune. RACE tune is 28-29 PSI with a wicked timing curve that produces the same 267rwhp or 320-330 crank hp.
- Supported mods needed: AA big turbo tunes for PV, AA high flow intake tube, AA high flow charge tube, AA clutch kit, AA blow off valve, AA slip-on exhaust or a slip-on exhaust that has the same flow. Power levels are shown with the AA exhaust with no quiet core installed.
- Mod includes: Machined compressor housing, billet compressor wheel, machined exhaust housing, high flow exhaust turbine, high pressure wastegate actuator, new bearings, head to turbo gasket, fully blueprinted & balanced turbo. Turbo looks new and is basically brand new when returned. We re-use the turbo to exhaust gasket as it's metal.
- Please package your turbo very carefully when sending it in, and be sure to insure for replacement cost ($1500 rough used cost Ebay, or $2500 for a new one). We would recommend at least a 12x12x12 or larger box. Remove the mounting bracket, but leave the wastegate actuator installed (we re-use a few bolts and it's easier this way). If your core has something wrong with it, just let us know... it's easier that way and we will find a solution. If it's just bad bearings, that's no big deal as we replace them anyways.
- ***Make sure you check your turbo for cracks. Unhook the wastegate actuator bolt and open the flapper. The OEM housings are known to crack between the wastegate exhaust port and the main exhaust port***
- Requires your turbo to be sent in for modification with a 2-3 week turnaround time.
- Send your turbo to: Aftermarket Assassins, 2348 75th Ave, Osceola, WI 54020 with a copy of your order

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.

Concise
Format: Paperback
I recently discovered how little I know about my own faith. This book is the second in a series of Penguin books on the history of the church. The author does an excellent job of providing an overview of the social setting of the middle ages and how the papacy, the East-West schism and the religious orders developed during this time period. I recommend this book to anyone who wants to understand more about how we got to where we are.

Sad to say Christians killed "infidels" too
Format: Paperback
A real eye-opener! Christians were killing "infidels" in the middle ages and the infidels were other Christians, Jews and Muslims.
