ADD MORE THAN 15WHP AND 20FT-LBS OF TORQUE
The ALTA R56 Front Mounted Intercooler goes hand and hand with other performance upgrades on your 2007 Mini Cooper S. While MINI was kind enough to install a factory intercooler at the front of your MINI, it is still very small and restricts performance. Seeing this as huge room for improvement we created the first and largest Front Mounted Intercooler for the 2007 Mini Cooper S!
Add roughly more than 10 WHP in about 3 hours of work! So far, the ALTA FrontMounted Intercooler is near the top of the list for best bang for the buck part available for the R56. Below are back to back results of our FMIC test on our 2009 JCW. The only part swapped between runs was the ALTA intercooler for the stock intercooler.
Below is some of the public testing we did showing our restrictive prototype FMIC making power, then backing up our final design intercooler showing how much more power it made over the prototype. Below shows our more restrictive prototype core, while not optimum it created a 5-10+WHP gain and 10-20ft-lbs of torque gain. This made a very noticeable difference in how the car accelerated. But with a few tweeks to the core we thought we could make more power.
Below is the test we ran showing the prototype intercooler and final design ran back to back, and with-in minutes of each other. Just like we expected to see, more WHP at the upper RPMs. All this while producting even cooler charge temps.

With this kind of data, and proof of concept, the ALTA FMIC is not going to be out done! More HP, cooler charge temps, makes for a more durable, safer tuned engine, not to mention better fuel economy!
Pressure Drop ALTA 1.5psi vs OEM 2.0psi
Temp in 280F
Temp Out 105F
Ambient Temp 70F
Intercooler Efficiency 83%
Tested at 25lbs/min which is about 250 Horsepower, and with 60MPH of ambient air flow.As shown before with our initial testing (found here in a thread on NAM),the intercooler can make a big difference in power with the stock ECU tuning. Now add your custom ECU tuning, more boost, and maybe even a bigger turbo, and the intercooler becomes a vital part to keeping your engine making safe big power. The below graph shows our initial testing of our prototype intercooler.
This graph shows our more restrictive prototype core, we
tested. While not optimum it created a 5-10+WHP gain and 10-20ft-lbs of
torque gain. This made a very noticeable difference in how the car
accelerated. But with a few tweeks to the core we thought we could make
more power.
While this graph shows it makes great power, this is
withour more restrictive prototype core. This core, while not
optimum,created a 10-20WHP gain and 20-30ft-lbs of torque gain, and
made a very noticeable difference in how the car accelerated.
We don’t use off the shelf cores and try to adapt them to our
applications, we build our intercooler cores to fit our needs. While
this process takes more time to get custom cores done, it allows us to
tweak how the core is constructed and how it performs. We cannot only
change the size of the overall core, but we can use different height
fins and bars, or vary the amount of fins, and type of fins. From this
we created an even better performing core you see today.
Why does the intercooler make more power than the stock one?? There
are2 main things that make an intercooler make HP. One is by cooling
the air better. A cooler charge of air, means denser air, which means
you can add more power to the engine with more fuel. (Luckily the ECU
takes care of adding more fuel). The cooler air also makes the engine
less prone to detonation/knock. The ECU is very smart and knows both of
these things (by seeing the cooler air) and not only adds more fuel,but
also adds more timing due to engine running safer.
The other reason that an intercooler can make more power is from it
being less restrictive. This is defined by difference in pressure
entering the core, and the pressure exiting the core. This “Pressure
Drop” happens no matter what, but the variable is how much. While the
variance from one to the next might be a couple PSI, this couple of PSI
effects the overall boost getting into the cylinders and how hard the
turbo has to work. If the turbo has to work harder, this can make the
efficiency of the turbo worse, and push out hotter air.
So now you understand how our core makes more power, and you have seen
our proven power. This is all with the more restrictive, less
efficient Prototype core and tanks!
Our Prototype core showed a huge improvement over the stock core, by
dropping the intercooler outlet temps as much as 40 degrees F. The
Prototype core we measured roughly 3PSI of pressure drop across the
core, where the stock one was around 2.2psi. Normally this would cause
a loss in HP, but the above proves that the air temp being cooler is
a big part of why it gains power.
With some tweaking of the charge tube count, charge tube heights, and
fin count, the Final ALTA R56 core further improves upon both cooling
and pressure drop. The intercooler outlet temps improved nearly
10cooler degrees F, compared to our prototype. Cooler air means more
power! The pressure drop of our prototype was a little high, so we
looked to improve this the most. Again with some tweaking we got the
pressure from about 2.8psi to a much more normal 1.5psi. So we
improved both pressure drop and the cooling of the intercooler with our
final version.
This info was something we have had for a while, now we have the
dynographs to back up the new design not only being more effective, but
also backing up the WHP it gains.
This test is with the prototype intercooler and final design ran
back to back, and with-in minutes of each other. Just like we expected
to see, more WHP at the upper RPMs. The above run was done quite
awhile after the initial testing, so the overall number isn't what to
look at, but the change from one to the other. Not only is the overall
WHP it gains very noticeable, but the ALTA FMIC looks really awesome on
the car!
Our Prototype and Final design core uses the same basic type of
core,known as bar and plate. There are 2 main types of cores, Bar and
Plate, and Tube and Fin. While both do very similar jobs, they are
very different cores. Bar and Plate (B&P) core are constructed
using thin plates, and aluminum bars (extrusions) with fins placed in
between all the parts. Its basically a big sandwich of plates, fins and
bars. The thickness of each layer, and the density of fins can be
changed to create the optimum pressure drop and cooling ability. These
are then baked in a vacuum, which brazes all the parts
together,creating an intercooler core! While there are more parts, and
more labor involved with building this type of core, they produce the
best most solid type of core.
Tube and Fin (T&F) core are limited to their charge side thickness
due to their construction. They are constructed using thin plates, and
thin extruded tubes. Between each of these tubes, fins are placed and
brazed together in an oven. The picture below shows the difference in
cores. The downside is the charge side of the core cannot be as wide as
a bar and plate, and also they are not very durable against rocks and
road debris.
This intercooler is a simple one in that there is a core, and tanks. We
explained why the core is made the way it is, next up is the tanks.Like
all other ALTA intercoolers we use cast aluminum tanks. This type of
tank gives us the freedom to create a perfect fitting, perfectly
contoured and perfect internally smooth part. No sheet metal here!
With this kind of data, and proof of concept, the ALTA FMIC is not going to be out done!
