We’re quite proud of this customer car The 1000cc injectors were maxed out, so hopefully with some larger injectors and full Q16 we’ll be able to break the 700 whp mark. Car was tuned with an Element Tuning Hydra by Phil from Element Tuning. I’ll let Phil contribute with his thoughts.

The car hit 649.3 whp on Q16/92 Pump 50/50 Mix, and 555.6 whp on 92 Pump + Water. Dyno and photos:

Hopefully, our previous engine management discussion didn’t overload your brain and just kept you coming back for more with this latest installment.  We pick up where we left off moving to the “Stage 3,” which typically involves an upgraded intercooler.  Just like with almost every modification we’ve discussed thus far, intercoolers carry with them some myths that many people believe to be true without ever having any personal experience to back up their claims.  But, before we get into those myths, it’s important to know what exactly the intercooler does in the first place.

The intercooler is essential to making power and maintaining efficiency on a turbocharged motor. There are two main types of intercooler:  air-to-air and air-to-water.  Most factory turbocharged cars use an air-to-air intercooler, since it’s much less complicated mechanically (no need for a water reservoir for heat exchange), not as heavy, and typically not as expensive either.  Air-to-air isn’t quite as efficient as a good air-to-water intercooler, but the cost/benefit involved tends to make the air-to-air intercooler the top choice is most situations.  Nevertheless, both types of intercoolers do the same thing:  they cool down the charged (compressed) air from the turbo so that it’s more dense when going into the motor.  As air is compressed, it generates heat, and heat also expands.  With more heat involved, there are less oxygen molecules, and with less oxygen going into your motor, the less power you can make.  The intercooler helps this by pushing this heated air to the intercooler core, which looks and acts similarly to a radiator.  As cool air passes over the intercooler fins, it helps cool down this air and makes it more dense as it then gets pushed into the motor.  Cooler, dense air contains more oxygen molecules, and thus you’re able to make more power.

Since the intercooler core acts as a heat exchanger, the size of the core determines how well or efficiently it can cool down the compressed air. The location of the intercooler core also matters as well, since it can easily be affected by ambient temperatures and needs proper airflow to do its job.  This is where a lot of the debate and myths start to come into play.  Subarus come stock with a top-mount intercooler (TMIC).  The size of this TMIC depends on the model and year of your car, with the STI TMICs typically being the largest offered from Subaru.  Given the size of the stock turbo (depending on the vehicle), the stock TMIC is usually perfectly fine for cooling and efficiency.  You can put on a larger intercooler and it won’t hurt anything, but you will need to get tuned properly for it and in the end, it might not yield much of a significant difference over stock.  Seeing gains of maybe 10 whp maximum typically isn’t worth the $900+ you’d have to pay to reach that much of a boost in power.

The location of the intercooler is the next matter of contention.  While the stock intercooler is located on top of the motor (hence the name top-mount intercooler), it really isn’t the most efficient place for the intercooler, especially when upgrading to a larger one.  The main reason for this is the simple fact that it sits not just on top of the motor, but also on top of the turbo, which of course radiates quite a bit of heat.  While the stock heatshield helps with this, when upgrading to a larger turbo, you can’t reuse the stock heatshield (or really any other heatshield for that matter) and thus the TMIC suffers greatly from heatsoak.  This is much more apparent when the car is stagnant such as in stop-and-go traffic or in line at the drag strip, rather than when the car is actually traveling at speed on the road.  In the case of the car actually moving, the stock hood scoop, combined with the stock air splitter, actually does a good job of helping provide proper airflow to the TMIC as well as shielding it from the ambient heat from the motor.  However, the problem then is with a larger TMIC, because the stock air splitter is not typically compatible with a larger TMIC, and in the case of an aftermarket hood, there simply isn’t any air splitter whatsoever.  This isn’t to say that a larger TMIC won’t do a better job than the stock one, but simply that there are definitely drawbacks to keeping the intercooler on top of the motor.

By far the best location for the intercooler is at the front of the vehicle.  Front-mount intercoolers (FMICs) draw air directly from the front of the car, which helps not just when the car is moving with air flowing over it, but also at a stop since it has direct contact with the outside air.  However, some people have insisted that by putting the intercooler at the front of the vehicle, there’s too much of a drop in pressure because of the added piping, and thus you will suffer additional turbo lag.  With proper tuning, this is completely false, and is normally a complaint from people who install a FMIC and do not get properly tuned or even tuned at all.  Owning two Subarus, both with FMICs, I can say with full confidence that there’s no difference in turbo lag whatsoever thanks to proper tuning.  However, there is indeed a pressure drop nonetheless, and thus it’s important to choose the right size core.

There’s always been the idea that bigger equals better, but when it comes to intercoolers, this isn’t necessarily always the case.  With Subarus specifically, there are some intercoolers that are just too large for the turbo its supporting, which causes too much of a pressure drop and thus a car isn’t able to make as much power as it could have with a smaller intercooler.  For example, the APS DR725 you see to the left here on Bailey’s car is gigantic, so it really wouldn’t be the right choice for a smaller upgraded turbo such as an 18G or 20G, and definitely a bad choice for the stock turbo.  Plus, given the fact that smaller intercooler cores such as the APS DR525, TurboXS, and Perrin are more than capable of handling well over 600 whp, you pretty much have to get a matching gigantic turbo to take full advantage of the DR725′s size.  Along with the size of the intercooler core comes the change in weight distribution, since you’re essentially adding 35 or more pounds to the front of the car.  Many would argue that this alone is reason enough to keep the intercooler in the top mount location, but generally speaking, this is more of a problem for those who do lower-speed racing such as auto-x, rather than types of racing that require the full power output, such as time attack and drag racing.  Finally, the other problem with a FMIC is purely aesthetic, since in most cases you have to do quite a bit of cutting of your front bumper cover to fit the intercooler there, not to mention you lose your factory bumper beam as well.  Most kits will include a replacement bumper beam of some sort, but it’s still not the factory, government-approved, and crash-tested bumper beam, so more frontal damage than expected is likely to occur should you get into some sort of accident.

Despite its drawbacks, we normally recommend FMICs to anyone who wants to bring out the full potential of the car.  It’s just important to choose the right size and design to suit your needs.  Of course, since a bigger intercooler doesn’t really benefit you without a bigger turbo, we’ll be talking about the different aftermarket turbos out there in our next blog entry.

In association with MySubie.com, we are indeed having a BBQ this year, albeit a relatively small one Robert and the guys from MySubie.com are coming into town and we’ve arranged to have a little BBQ and meet during the limited amount of time that they’ll be here. They really want to meet some fellow Subaru folk while they’re in the area, so please come on down and enjoy some BBQ goodness! We’re well aware that not everyone would be able to make it down on a MUNday night, but this was the only time available for the MySubie.com guys.

We will be providing some burgers and hot dogs out of the back of our shop where the grill is located, but you’re more than welcome to bring chips, soda, and perhaps more items to grill if you like. Weather-depending, we might be able to take some photos behind the shop as well. All photos of course will be featured on the World One Performance Blog. I know that Robert had mentioned doing some sort of after BBQ cruise of sorts, but we’ll probably play that by ear. Robert even has this even listed here:

Please drive around to the back of the shop, since this BBQ is being held after normal business hours

In its fourth year coming to the greater Seattle area, Formula D returned stronger and more exciting than ever this past Saturday, August 8th. I’ve been covering Formula D for Subiesport/DrivingSports each year it’s come to Seattle, and I honestly do believe it gets better and better every year. In past years, I’ve endured scorching heat (100+ temps on the track) and pouring rain, but this year the overcast weather held up nice and dry, without being too hot or too cold. While the weather conditions seemed ideal all around, the newly redone track surface proved to be challenging for most of the drivers this year, resulting in more crashes, injuries, and broken cars than any of the past 3 years. Dai Yoshihara had a mechanical failure in his Lexus IS350 in practice that resulted in him slamming into the wall right at the first break and he had to be taken to the hospital with a mild concussion. Other cars lost front and/or rear bumpers, Ken Gushi’s Scion tC broke a driveshaft, and even the Pro-Am racers preceding the Top 16 raced fender-less and with duct-taped hoods. All of this action continued to wow the packed grandstands and paddock, to which the Formula D officials always mention as being among the best crowds throughout the entire tour. Ultimately, Chris Forsberg in the NOS Energy / Maxxis Tires Nissan 350Z went on to win the event and widen his points lead for the Formula D 2009 Championship.

Being among the crowd and the media, it was clear to me that Formula D could be seen as a saving grace for the import car enthusiast scene in the greater Seattle area, or perhaps even the entire Pacific Northwest, including British Columbia. With Battle of the Imports not coming to the Seattle area this year and all of the major import car shows canceling their Seattle and Vancouver BC shows this year as well, the import car enthusiasts in this area very much need an event like Formula D. I believe that given the sheer numbers and enthusiasm of the crowd, many of these people would agree with me. Those of us who live in this are can only hope that more events such as this will pay visit to the greater Seattle area next year.

Tomorrow, I’ll be at Formula D Seattle not only participating in the car show, but also taking photos on track for Subiesport Magazine and DrivingSports.com. I’ll be sure to share a few photos here, but you’ll most likely be able to view them on DrivingSports.com once processing and uploading is finished. To the left, you see me still holding down the shutter on the camera while the AE86 loses control and drifts toward the barrier…lucky for me, he came to a stop right before hitting it, but I was still pretty scared.  Hopefully it won’t rain like it did last year! Until then, please feel free to browse my past Formula D Seattle photos at these links below:

Continuing from the other day’s blog, you can see we’re obviously a day behind. But, let’s continue without delay!

The UTEC quickly became the go-to form of engine management between 2003 and 2004, but soon Cobb released their own AccessPort to compete with the UTEC. The AccessPort was a reflashing device instead of a piggyback ECU, which offered several advantages. Being a reflashing device, nothing needed to be installed between the stock ECU and the car (like how piggybacks are installed), and since it reflashed the stock ECU, it was similar to the ECUtek in terms of tuning resolution. Since this reflashing was done through the car’s OBD-II port under the steering wheel, the AccessPort could also be used to log and/or display types of data, such as RPM, throttle position, and more. The AccessPort also included pre-made basemaps for specific engine mods, which made it just as easy, if not easier to use, than the UTEC for those who are not interested in doing their own tuning. Cobb eventually released their own AccessTuner to allow users to do their own tuning, but it was a separate option and not included as part of the standard AccessPort package. For those who didn’t care to tune their own car, Cobb gave their dealers with AWD dynos the option to do “Protunes,” which allowed for professional tuning via the AccessPort at a shop. These Protunes could also be saved and distributed, so many Protuners released their own maps to match specific modifications as well. Despite some initial hiccups to get all of the basemaps working properly and safely for all vehicles, the AccessPort went on to become a huge success for Cobb Tuning, and it eventually overthrew the UTEC for the king of the hill in affordable engine management.

However, the basemaps that both TurboXS and Cobb supplied did have their disadvantages. In order to maintain safety, these maps were tuned for the lowest common denominator and were specific per octane level as well, to ensure that customers would not blow up their motors. While they still improved performance over being untuned and they kept the motor healthy, there was still always going to be room for improvement with a custom tune for each specific car. This still remains true today, although the margin for improvement has been able to shrink with some new engine management options available. The other problem (although not a problem for most people) is that you typically have to follow a specific mod path for the basemaps, and if you stray away from that, you have to get a custom tune for your car no matter what. While for big horsepower applications a custom map is a given, simply changing your intake away from the stock airbox is enough to warrant a custom tune, except for intakes specifically developed by TurboXS and Cobb Tuning respectively. As mentioned in the previous blog, the stock airbox is rather efficient so this may not be a big deal, but not being able to change the intake without a custom tune does put limits on your freedom of modification. Striving for more freedom of modification, other companies sought out to create another option for those people who wanted to not only wanted more freedom than he UTEC and AccessPort offered, but also get away from the limits of the stock ECU itself.

Enter the Element Tuning Hydra EMS. In 2005, Element Tuning entered the fray with their version of the Hydra EMS. The Hydra is a standalone ECU that completely replaces the stock unit. While standalone ECUs of the past required the user to tune every aspect of the car’s behavior from simply idling all the way up to wide-open throttle, Element Tuning took this difficult and time-consuming process out of the equation by taking care of all this programming already, as well as shipping the Hydra with basemaps specific to each car’s modifications, much like the UTEC and AccessPort. Moreover, Element also had maps available for a wide variety of different sized turbos, water/alcohol injection, and different sized intercoolers and intakes. The Hydra also had equal or better tuning resolution than the stock ECU, thus a basemap from a Hydra would typically be more accurate than that of a UTEC or AccessPort. This lowered the amount of custom tuning that would need to be done, but of course a custom tune per vehicle would also bring out the full potential of the car’s setup, which of course was easily possible with the provided software. On top of all this, the Hydra was also very adaptable to different environmental conditions, so the problem of having a map tuned for sea level and then needing a completely different map for mountain passes was effectively eliminated. Our own World One STI back in 2004 actually had a prototype Hydra EMS that helped it finish 2nd in its class and 6th place overall at the very first Primedia Time Attack. However, as good as this system is for tuning and adaptability, it also had its disadvantages, especially for daily drivers. The main issue is that because it’s a replacement to the stock ECU, it does not support OBD-II, and thus it will not pass emissions in just about every state in the country. The other issue, although it may be a very minor issue to some, is that you also lose your cruise control, however this is problem is apparently being fixed for the 08-09 STI. AEM soon followed up with their own plug-n-play Hydra EMS, but not until just in the past year, so support and available tuners aren’t quite as available at this time currently.

Since the release of the Hydra, both TurboXS and Cobb Tuning have updated their UTECs and AccessPorts respectively to add more features, but yet another option was introduced in 2006 that has since thrown the engine management market on its head. A group of computer-minded enthusiasts put their minds together and were able to connect to the stock ECU and then go on to start programming it. It took awhile to get things reliable and easier to use, but as it stands today, this Open Source style of tuning using the OpenECU software has become an easy entry point for customers to start tuning their own vehicles, especially since the software itself is free to download. The only purchase necessary is the Tactrix cable, that allows you to connect your laptop to your car’s OBD-II port (much like how the AccessPort connects). While OpenECU is always in a state of development, many tuners have embraced the software and use it as their primary form of tuning, allowing them to tune to the same levels as that of the AccessPort and ECUtek. Of course, the drawback is that you have to rely on user support rather than having any guarantees or formal support from a company, so in many cases, you’re on your own.

Overall, Subaru owners should be thankful that they have so many choices available to them. This isn’t the case with other makes such as Mitsubishi and Nissan. No matter what form of engine management you choose, it’s always important to understand that how well your car performs is going to depend on how the car is tuned, whether that’s strictly from a basemap or from a custom tune. If you go with a custom tune, be sure the you go to a reputable tuner that has experience tuning the type of setup that you have. After all, just because someone can tune a 300 whp car doesn’t mean that they won’t have any problems tuning a 600 whp car. As always, if you have any questions, please feel free to contact us or post a comment here. For our next part in this series, we’ll be talking about intercoolers, both top mount and front mount, and how they can affect your car’s behavior.

Last week, we finished discussing the different downpipe options out there, but before we get started with intakes and engine management, I just want to make note of the title change of this particular blog series. The reason for this is that it was mentioned to me by a reader (thanks, Mike!) that this same advice will also apply to Legacy GT and Forester XT owners as well. While some of the designs of the exhaust components may be different, the motors all behave similarly since they’re almost exactly the same anyway. Thus, if you’re a Legacy GT and/or Forester XT owner, don’t fret: these same mods will work for you too!

Anyway, we’ve covered the turboback portion of the exhaust, so now let’s talk about the intake. Just like with some of the exhaust myths we previously discussed, the intake has many myths associated with it as well. Some people have insisted that any and all aftermarket intakes are bad for your car, and that your car will soon near explode if one is installed. This blatant generalization is really quite false, and while some aftermarket intakes do not work as well or are as properly-designed as others, putting on an aftermarket intake is not going to spell instant death for your Subaru. In fact, it was proven in the November 2008 issue of Subiesport Magazine that intakes do make a difference, and that certain intakes are definitely better than others, especially after tuning. Thus, if you’re afraid that getting an intake is going to hurt your car, as long as you choose wisely, everything should work out just fine. While the stock airbox is actually very efficient and is already by design technically a cold air intake, an aftermarket intake will provide a noticeable increase in throttle response, since the higher flow of air will help your engine rev faster. This higher flow of air however can pose some problems, especially the farther along you go in your power mod path.

These problems arise when choosing your engine management options. Unlike other cars, such as the Evo, the stock Subaru ECU (or “engine control unit”) can be very temper-mental, depending on the mods you put on the car before tuning. Just like how the myth propagated that an aftermarket intake will blow up your car, a similar myth has been attributed to the turboback exhaust system, with some claims that installing a turboback will void your warranty. This is absolutely not the case, and we’ve even fought a local Subaru dealership and won in a warranty fight, with Subaru of America themselves ordering the dealership to provide warranty service to our customer’s car. In any case, this “if you install this mod, you’ll blow up your car” nonsense ties in to engine management, since now the phrase has become “if you install this mod, you’ll blow up your car UNLESS you get some engine management.” The truth is, YES, your car will perform better when tuned properly with good engine management, and YES your car will be more reliable and safer when tuned properly with good engine management, but NO your car will NOT blow up just because you installed an aftermarket intake and an aftermarket turboback exhaust system. Obviously, this doesn’t take a person’s driving style into account, but the whole idea of instantaneous motor death is ridiculous at best. We still very much recommend engine management at this point, but more because it’ll truly bring out the full potential of the car (especially when tuned properly) and because the car will perform better and more reliably, but not because it casts some sort of protection charm over you motor.

So, if engine management isn’t absolutely and completely necessary at this point, at what point is it? The intake and turboback modifications we’ve discussed are still really basic bolt-ons, thus the temper-mental stock ECU can still do its job without too many problems. However, the additional airflow both into the motor and out of the motor does confuse the stock ECU a bit, hence why engine management at this point is definitely recommended to get the ECU back on the right path. Beyond this point, when you add even more air flow (such as a bigger turbo, intercooler, and intake) and also more fuel (such as larger fuel injectors), the stock ECU simply does not know what to do, and thus engine management is absolutely necessary. Often times, the car simply will not idle or run at all without engine management and these additional mods. Thus, to put it plainly: for an intake and turboback, you’ll probably be just fine, but for anything more than that, you’ll definitely want engine management.

Now that you found a need for engine management, either because you’re going with big power mods or because you just want your turboback to perform to its fullest potential, what’s the best engine management choice? This is where things could potentially get complicated. There are three main forms of engine management available for Subarus:

ECU Reflash

• Cobb Tuning AccessPort
• OpenECU
• ECUtek

Piggyback ECU

• TurboXS UTEC
• Dastek Unichip

Standalone ECU

• Element Tuning Hydra EMS
• AEM EMS
• Tec3
• LinkECU
• MoTec

While each of these forms of engine management accomplish the same basic principles, they each do it in different ways, and ultimately to different levels of success as well. An ECU Reflash uses the stock ECU, but loads different maps on it to control the motor, allowing the stock ECU to still control other functions such as the HVAC and cruise control. Piggyback ECUs are small computer devices that act as a middle man between the stock ECU and the rest of the car, with one end plugged into the stock ECU and the other end plugged into the car’s wiring harness. Finally, standalone ECUs completely replace the stock ECU with a new one.

Back when the WRX first made its way across the Pacific in 2001, the two main engine management solutions available at the time specifically for the WRX were the ECUtek reflash and the Dastek Unichip, which was offered by TurboXS and Vishnu Performance. The ECUtek reflash worked and still works well, but the license to be an ECUtek programmer was/is on the very expensive side, so typically these reflashes needed to be performed by a shop every time. The TurboXS and Vishnu Unichips on the other hand had a pre-installed basemap to suit specific level of car modification right out of the box, and could be further programmed by an authorized tuning shop specifically for each vehicle. The difference between the different company’s Unichips was how the basemaps were programmed and how they would connect to the car, either via a wiring harness or if they had to be hard-wired. It was from TurboXS’s “Stages” that we get the Stage 1 to 4 levels that we still use to this day: Stage 1 was for a Unichip and catback only, Stage 2 was for a Unichip and Turboback, Stage 3 was for an added larger intercooler, and Stage 4 was for an added larger turbo, injectors, and fuel pump. Anything more than that was simply considered “Stage 4+”. Since both Unichips came with a preloaded map to match your level of modification and it was a relatively easy install, the Unichip was by far the more popular option at the time. However, one problem with these preloaded basemaps is that they were designed specifically for the airflow of only the stock intake airbox, and thus aftermarket intakes were not compatible with the preloaded basemaps, and therefore required custom tuning. This caveat has been an issue with many later forms of engine management, including the Cobb Tuning AccessPort we all know and love today. Nevertheless, people (myself included) happily removed the aftermarket intake they purchased and reinstalled the stock airbox to ensure that the Unichip was happy and performing properly. Standalone ECUs such as the Tec 3, LinkECU, and MoTec existed, but since they did not have the same plug-n-play functionality of the Unichip, they were often only used by more hardcore WRX modifiers. After all, the last thing most customers want to do is spend hours tuning their ECU just to get their car to idle correctly, let alone actually increase performance over stock.

Over time, the Unichip started to show some problems. For one thing, certain Unichip owners would find that the pre-loaded basemap on their Unichip would either simply be erased over time, or the stock ECU would actually override the Unichip, rendering it completely useless. The Unichip’s tuning resolution (the actual increments and scale of tuning certain things such as air/fuel ratio and ignition timing at specific RPM) was also nowhere near that of the ECUtek, so even the custom tunes did not end being as good as they could have been with better resolution. Given the problems they were having, TurboXS went on to develop and release the User-Tunable Engine Computer, or “UTEC.” The UTEC was a big step forward in not only tuning resolution, but because it allowed the user themselves to actually tune their car, rather than requiring a shop to tune it for them. TurboXS still provided basemaps to start from, and the user could load them onto their UTEC via laptop or taking the UTEC out of their car and plugging it into their home computer. This opened up a world of possibilities for many people, some of which are now prominent tuners who first started out tuning on the UTEC. Vishnu attempted to answer TurboXS’s ante with their own “XEDE,” but the XEDE proved to not be quite as versatile or as easy to use as TurboXS UTEC, and soon Vishnu abandoned Subarus and moved on to the brand new Evo market (which they also eventually abandoned).

See as this blog is starting to get quite lengthy, we will conclude this discussion on engine management in tomorrow’s blog.

Although not brand-spanking new, the StopTech Trophy-series Big Brake Kits are already starting to make a name for themselves in the motorsports world.  here’s a short description from the StopTech/Centric press release:

These racetrack and competition brake systems come with StopTech’s new Trophy STR lightweight forged calipers in four- or six-piston configurations and include the option of a quick release version of the StopTech patented bridge. These “track only” calipers feature the same metallurgy and design of the StopTech ST-40 and ST-60 calipers, but are engineered to provide a 20-percent reduction in weight without sacrificing stiffness or performance…

StopTech Trophy Big Brake Kits include the company’s patented AeroRotors, engineered to increase airflow by 11 percent for better cooling and performance. Unique to the Trophy Brake Systems is full-floating mounting hardware, which eliminates pad knock-back. The patented, billet 7075 aluminum AeroHats create an additional 4 percent airflow. Together, these technologies optimize the rotor system to provide even performance and consistent feedback to the pedal under the unique combination of hard cornering and braking found on the track.

The StopTech Trophy calipers and AeroHats use an exclusive, high-temperature “natural” finish that combines with the AeroRotor for an attractive and attention getting in-wheel presentation. The kits also include billet aluminum mounting brackets with stainless steel caliper studs and DOT-compliant stainless steel braided brake lines. All StopTech Big Brake Kits provide larger rotors that increase heat capacity and dissipation coupled with stiffer calipers and stainless steel lines that reduce system compliance. The results are shorter stopping distances, better brake modulation, firmer pedal feel and less brake fade, resulting in stronger, more reliable performance.

StopTech Trophy Brake Systems will be available through motorsports distributors in January 2009 for selected high-performance production cars including Porsche, BMW, Mitsubishi Lancer EVO, Nissan GTR and 350Z, Chevrolet Corvette C5 and C6 and others. StopTech will premiere the Trophy Brake Systems at the Performance Racing Industry Show in Florida this month at booth 3958.
