Hello everyone.....

Here's another new product only from the minds of M7--simple, beautiful and a performance upgrade at the same time. The M7 APD is made from carbon fiber, superstrong and light weight, with a deep clear coat finish.

Price: $149.00

Available very soon (2-3 weeks).

We will have this unit for everyone to see at the Monterey Historics.
And it will travel across the country on a car owned by Steve Tech
from Fresno, his Company Custom Mini Shop will showcase this new part
for everyone to see.

M7 Air Plate Diverter

Modern internal combustion engines produce a great deal of heat while producing power. To avoid damage due to overheating, a water to air heat exchanger, or radiator, is used to transfer the heat from the metal block and heads to a mixture of antifreeze and water, and out to air moving through the radiator. Effective heat control, then, relies heavily on efficient and consistent flow of cooler air through the radiator.

The MINI's distinctive front end has two openings in front of the radiator, one low in the bumper and one at the front of the clamshell bonnet. Though this would seem to be advantageous for more air flow, the design leaves room for improvement. The openings are separated in the fascia by a solid bumper that blocks a significant portion of the radiator's cooling surface from fast moving, direct air flow. In this case, to move air through the blocked portion of the radiator the design relies on a pressurization of the open area between the bumper and the radiator. Since the area behind the radiator is at a lower pressure, this works in theory. Unfortunately, the theory is not always reality.

At the top of the bumper on the MINI, there is an open gap between the lower inlet area and the grill inlet on the bonnet.


This area allows air to pass freely between the two openings. This could allow for the open area to act as one single pressurized region to force air to flow through the radiator, but in truth it's likely more detrimental to efficient cooling.In the lower section there is a second heat exchanger for the air conditioning.To cool correctly, the air must pass

through both, but the longer flow path presents a larger resistance to flow than the section of the radiator not covered by the AC heat exchanger. This leads to an interesting effect that can be seen with fluid flow analysis.


The first simulation was run as the stock setup, with the area open. Upon a quick inspection of the results, several oddities should become readily clear. The first is that there is a section of the radiator where there is no flow (1)! The air that should flow through that part of the radiator (2) is following the path of least resistance, flowing up and over the double thick region and through the single region above leaving a significant portion of the radiator with no cooling air flowing through it. This will reduce the efficiency of the radiator.

Always thinking, M7 has developed the Air Plate Diverter (APD) to help stop the migration of the cooling air from the lower inlet to the upper section of the radiator where it is not needed. The APD separates the two open areas behind the bumper and bonnet, trapping the air. As the simulation shows, with the M7 APD installed the pressure buildup in the lower opening will force the air to move through the entire radiator. There is no more dead spot as there is no longer a path of less resistance for the air to take. The M7 Air Plate Diverter will increase the efficiency of your cooling system.
