White Paper – Matt’s BMW F80 M3


Our friend Matt (Money2536) is well known around here as having exquisite taste, whether with his choice of cars or stunning home and garage where they are kept. Some of you may remember his LeMans Blue E92 M3 we featured back in 2013, still one of our favorites to this day. We don’t encounter too many with his particular brand of OCD either – and by that we mean the best possible kind. His step-by-step detailing guides are in-depth enough to be on a professional level, and it is with this laser focus he envisioned the first round of modifications for his pristine Mineral White F80 M3.

Ordered with a 6-speed manual and SO interior, this new M car didn’t make it very long before the ideas started flowing, and the results are mild yet effective, as you can see here. We understand the Akrapovic system may be soon departing, but we have no doubt whatever follows will be money, in every sense of the word.

Mod List:
BMW Performance black front grilles
BMW Performance black side gills
BMW M Performance trunk spoiler
IND MW key hole cover
IND MW F/R reflectors
IND gloss black license plate frame
RKP front lip
K&N filters
Dinantronics tune
KW HAS kit
15mm Turner spacers F/R
Akrapovic Evolution full exhaust with carbon tips

BMW 2015 M4 Safety Car


From Press Release: “BMW M has always been synonymous with technological innovations, and we are delighted to be able to present another new highlight this year: in the near future, BMW M Division will begin production of a model featuring water injection. Water injection is a system designed to increase the performance and reduce the consumption of combustion engines. We will be using this technology in the BMW M4 MotoGP Safety Car for the 2015 season for the first time.

Increasing the supercharging intake pressure would exceed the knocking limit and is therefore not a viable means for increasing performance. BMW M Division has a solution: injecting a fine spray of water into the collector once more significantly reduces the temperature of the combustion air. The cooler supercharged air reduces the engine’s tendency to knock, making it possible to bring the point of ignition forward and thus closer to the optimum value. This makes the combustion process more effective, whilst at the same time reducing the combustion temperature. On the other hand, cool air has a higher density which increases the oxygen content in the combustion chamber. This results in a higher mean pressure during the combustion process and in turn optimises performance and torque. Finally, the effective internal cooling of the combustion chamber reduces the thermal strain on numerous performance-related components. This not only prevents damage to pistons, exhaust valves and catalytic converters, but also reduces the strain on the turbocharger, which is subjected to lower exhaust temperatures.

The lower process temperatures also reduce the formation of hazardous substances, in particular nitrogen oxide (NOX). Water injection consequently dramatically improves the effectiveness of the engine. Using water injection to increase the knocking limit also helps to largely resolve a familiar conflict in objectives when designing powerful engines. Performance and consumption are not least determined by the compression ratio. This also applies, in particular, to highly charged turbo engines like the BMW M TwinPower Turbo, inline six-cylinder. Thanks to a high compression ratio, this engine is highly efficient and boasts low consumption figures, especially in the partial load range. However, the maximum compression ratio is limited by the knocking tendency when fully loaded. Water injection is also hugely beneficial here, as it reduces the tendency for the engine to knock, whilst at the same time increasing the compression ratio. This way, the turbo engine can achieve optimal performance across a wide range of operating points.”

Duel Pursuits – BMW F80 M3 vs. F82 M4


One of the true joys of having a new and popular BMW M model released is that there are a lot of enthusiasts building their cars right alongside yours. Some end up very similar, yet with small distinct touches. Others might drastically diverge into worlds apart – and this concept is the basis for what you see here today. Yes, if you are wondering, we did struggle to resist the usual “ketchup and mustard” references!

While the team here at PSI knew well in advance that our M4 Club Sport project was bound for SEMA and beyond, through several drastic evolutions, our friend Joe started with an entirely different car, and then continued on his own path. While there are a few basic similarities between our two approaches – mostly in that they are both the current F8x platform – in some ways you couldn’t ask for a greater contradiction. At their core, one is a yellow four-door M3 with manual transmission, and one is an orange two-door M4 with DCT. Night and day comes to mind.

If anything, our opposing processes and styles prove yet again that creativity plays a large part in the art of modifying a car, and two end results at opposite ends of the spectrum can certainly be appreciated by everyone involved. Rather than finding yourself stuck in the rut of having largely the same modifications as several others, realize that there are an ever-growing combination of colors, brands and variations out there – certainly far more than we have installed on these two M cars.

By staging a duel here today, even though each build is worlds apart, we can find a lot of common ground between these two polar opposites. We hope you can too!

New Photos of the Vorsteiner GTS-V Front Lip Spoiler

We noticed that there have not yet been many – if any – photos showing the new GTS-V carbon fiber front lip spoiler for the F10 M5 by Vorsteiner. As with the E9x M3 and the F1x M6, this new GTS-V aero piece is much more of a motorsport design than the initial VRS Aero front spoiler.

Similar to the other GTS-V models, this carbon fiber element retains a flat, horizontal lower section for smoother airflow and integrates large brake cooling ducts within the design. This results in a similar look and function to the M3 GTS aero, and a more aggressive appearance from any angle.

Here are a few shots of the familiar Vorsteiner M5 with the new GTS-V front spoiler installed. Enjoy!

Remus Exhaust Released for BMW F8x M3 + M4!


Good things come to those who wait, and we are very excited to show you the brand new Remus Sport Exhaust system for all BMW F8x M3 and M4 models! Remus is a premium exhaust manufacturer from Austria that manufactures high quality exhaust systems for cars and motorcycles. We have been eagerly awaiting their M3/M4 products, as thus far we have not come across a setup that we liked that combined build quality, proper tone, and affordable cost. Today, that changes.

This is available in either a rear axle-back muffler section or the complete downpipe-back system with connecting pipes, X-pipe, and rear section. Both options include your choice of 4 different tip sizes and styles, including 102mm angled carbon fiber with titanium internals, 102mm angled chrome, 98mm non-angled black chrome with carbon insert, and 98mm non-angled stainless with carbon insert.

The Remus setup will eliminate your OEM front silencer and secondary catalytic convertors, a feature specifically designed by their engineers to increase the exhaust note and tune the sound characteristics for a particularly pleasing effect. Having heard this exhaust in person, we can verify that this works very well!

With either system, the OEM exhaust valves and controllers are integrated into the design rather than eliminated, allowing full use of the existing Sport/Sport+ functions for variable control.

Enjoy the photos!

To Infinity And Beyond: PSI In 2015


We are well into January, so we thought we would give you a little preview of how 2015 looks like to us. PSI has always been in the business of providing BMW enthusiasts the very best service possible, and we plan to continue building that benchmark in the years to come. Our shop M4 “Club Sport” will undergo some changes designed to show its ever-evolving journey, and we have committed to immersing it into the world of motorsport, with several events planned.

Additionally, we are working on a similarly track-themed E9x platform car that will be built for competition use. We can’t get into too many details as of yet, but expect more from us than you’ve ever seen before. As always, we offer full service and maintenance in addition to our repair and performance options. With nearly a full month under our belts, PSI is showing no signs of slowing down as we enter 2015, and we have you to thank for all the support over the years! Drive safely and we hope to see you down the road.

Vorsteiner Official Release: New M4 Photoshoot + Video

There is a reason we drove across the country from LA to Orlando with a set of Vorsteiner Flow Forged wheels mounted on our M4 recently – we believe firmly that they are some of the best rolling stock on the market today, offering strength, visual style, light weight, and functional durability.

Shortly after our own cross-country photo journal was released, prominently featuring a set of V-FF 103 Flow Forged wheels, Vorsteiner sent us a shoot of their own with the exact same models installed on another M4, in a breathtaking location. Additionally, we are sharing a short film highlighting the entire V-FF Flow Forged range.

A Little Look Back 2014, Part II

Before we wrap up our 2014 year in review today, we would like to remember two significant projects that departed from the shop – gone but not forgotten.


Project Fire – E92 M3

Sadly, this had to go to make room for the incoming M4. Once built to depict our version of the fabled M3 GTS, it was returned to stock and sold to a fellow enthusiast.


AA Supercharged E46 M3

This black beauty was our shop manager’s car, and when he departed to continue his career, he decided against donating it and took it with him. We think we know why – it’s awesome.


New F82 M4


Nothing like a brand new M4 to help you move on! This car arrived and was literally transformed in one evening, undergoing cosmetic and suspension changes that dramatically altered its appearance.


Austin Yellow F80 M3


While this technically wasn’t a major build in the traditional sense, we felt it was important in that it was one of the first F80 M3s in the country to be altered with springs, spacers, grilles, a JB4 and new wheels. Plus, it’s gorgeous!


M4 Club Sport – SEMA Build


We knew the first phase of our M4 was only temporary, and our build for the SEMA Show had to be pitch perfect. Thanks to some amazing parts and a lot of hard work, we managed to pull it off!


This was probably our defining moment of 2014 – entering our M4 into such a major automotive event, and then driving it back across the country as you all saw last week. We have more plans for the coming year, and we believe 2015 will be our best yet! Thank you all for your support and your friendship, and we hope to see you down the road.

Happy New Year!

A Little Look Back 2014, Part I

While we admittedly are looking ahead to 2015 with great anticipation and excitement, we also enjoy remembering what the last twelve months have brought us – friendships, memories and the inevitable winds of change. Without any further sentimentality, here are several of our favorite moments from 2014.

M To The Power Of 1

This was the latest iteration of a beautiful 1M we were able to build. We do seem to get our share of orange cars.



The Italian Distinction – Lamborghini Gallardo

While not a BMW, it would be near criminal to overlook this screaming stallion of a car, to which we added a Fabspeed exhaust, some carbon fiber, and those Verde Ithaca brake calipers.


E36 Centerlock Conversion

Our technicians will be the first to tell you that there is a lot more done to this car than the coilovers from BC Racing and that delicious centerlock conversion and wheels from Hard Motorsport.


Full Yellow Jacket

It is hard to miss this blinding yellow Z4 feature, with some very tasteful modifications and an overall appearance that approaches perfection.
