This kit is supplied with:

Differential Oil Pump
Mocal Differential Cooler
All Fittings Necessary to Complete Install
10 ft length -10 Aeroquip Hose
Instructions

Some post 2006 applications may require slight alterations to fittings.

A number of things contribute to cooling efficiency, e.g.; fluid capacity, fin design, material, etc. Zionsville Autosport's Alloy Radiator has a core thickness of 43 mm. The surface area of ZA's e38 - e39 alloy raditaor is 376 square inches - the same as a stock radiator. Additionally, we use a high efficiency core similar to a stock radiator. High efficiency cores have more fins per inch, more tubes per core and more cooling capacity. Each row has a single, large tube. The flat side of the tube is in direct contact with the fins which transfers heat from the tube walls to the fins. Since the rounded ends of the tube are not in direct contact with the fin, this portion of the tube does not aid in secondary cooling. The more tubes per row, the more rounded ends, and the less direct contact there is between the tubes and the fins. ZA uses a single tube for better heat dissipation.

The E39 M5 Super Duty Cooling Kit... The alloy fan shroud and electric fan work in concert to provide maximum cooling efficiency by pulling 2070 cfm through the radiator core - even while sitting still if required by engine temperature. Simply hanging a fan on a core is inefficient as airflow must be directed through the entire core area, not just directly in front of the fan. The latter approach limits the effectiveness of the core. Essentially, it reduces the core size to the diameter of the fan. Not to mention the fact that hanging a fan through the core will eventually fatigue the cooling tubes and lead to failure.

The alloy shroud in combination with the electric fan creates a low pressure area behind the radiator in order to pull air through the entire core surface. (The front of the core is exposed.) The concept is a refinement of the BMW design. Our kit features improved sealing of the shroud and increased air flow without the parasitic drag of an engine-driven fan. We have also been advised by both customers and technicians that the engine fans are disintegrating at around 100k miles, taking out the cooling system and damaging the hood of the car. Our design incorporates a caged electric fan with a safety shroud and lighter weight individual fan blades. The result is improved safety and efficiency.

With regard to the expansion tank, we have been advised and personally experienced tank failure through rupture of the main expansion tank. Our thinking is that due to higher heat soak temperatures on V8 and V12 cars, the tanks are heated/ pressurized beyond their limits. As a result, we designed an alloy expansion tank with greater resistance to degradation caused by the more extreme temperature limits in V8 and V12 cooling systems. Our tank does incorporate some of BMWs features; e.g., we retain the original cap and the internal plumbing.

The cap design is very clever: it facilitates the expansion and contraction of coolant, while at the same time offering an escape route for atmosphere and coolant when pressure in the system threatens passenger well being * and cooling system integrity. The topping off process requires filling the tank until one half the level is maintained during the initial fill, then topping off after a driving cycle, once the cooling system is cold. As in all our radiators, the alloy construction of the radiator also improves efficiency through an increase of radiant surfaces and enlarged storage capacity.

With the 2 speed fan kit, the fan operates on low speed or high speed based on engine temperature. High speed comes on only when necessary. Running the fan through a resistor allows us to back the speed down when the extra volume is unnecessary, creating less wind noise.

* Otherwise, the heater core could rupture and spray coolant inside the passenger compartment

OUTPERFORMS EVERY OTHER FAN ON THE MARKET!

These State of the Art cooling fans are wind tunnel developed. Made of Dupont Minlon, they offer exceptional strength and durability, the motor has a lifetime guarantee. No unnecessary mechanical cooling.

Fast warm-up in winter, cost effective, fuel efficient - easy to install. All Pacet fans now come with high output motors.

PACET specialise in coaxial fans. These have advantages of using little in the way of space and have a relatively small amp draw in the system.

Pacet use permanent magnet motors, manufactured to their design and specification, most are with twin ball bearings, radio suppressed and water resistant to beyond industry standards. Permanent magnet is more expensive to produce but uses less than half the power of other after-market and OE fans. This is a vital factor when adding to a standard vehicle's power loading.

This Remote Oil Sensor Manifold is designed to facilitate the installation of Oil Pressure or Temp sensor/s.

Originally designed so that the S14 owner can send oil to this manifold, install an aftermarket gauge and still maintain the OEM "emergency oil pressure" dummy light- it had become popular as a quasi-universal item.

Popular on cars that read artificially higher oil temps at the sensor due to the location of the exhaust manifolds or other issues.

•(1) 1/8 NPT Inlet
•(2) Sensor holes: 1/8 NPT + 12x1.5 Metric

This manifold is designed for easy installation with two mounting holes to sheet metal.

Notes:
•Sensors and fittings are sold separately.
•(Due to the fact oil doesn't flow through this type of manifold, Oil temp is not a recommended use for this piece, pressure is ideal).

An excellent upgrade for those who race or have a modified / Forced induction engines, this is the best OE style oil pump available anywhere.

Lubrication issues are a common killer of BMW engines. The dual-pickup pump is much better than standard single pickup but this pump is a dramatic improvement over both.

This oil pump starts with an OEM housing (either supplied by you, or as a core from us at extra cost) that is expertly modified to provide higher volume and improved reliability over stock.

Effective lubrication is critical to all high performance engines, especially the high specific output S54 & S50. The S54 especially, with its narrow rod bearings is sensitive to oil starvation and bearing failure. Assuring that your engine will not fail due to a poor lubrication is crucial during all operating conditions.

This pump features two important upgrades:

1) Engineered using the Oil Pump Upgrade reinforcement kit ( as featured elesewhere in this section) integrated in it's design; giving a stronger gear drive mechanism for much lower likelihood of the common pump failures on the track or hard road use.

2) Fitted with custom gear set with a larger sweep area to the pump mechanism, increasing volume by 22%.

Important Notes about this Service:
A good used or new oil pump is required for this conversion service. Therefore there are 3 options:

1 – We send you a new OEM BMW Oil Pump with the high volume converson and oil pump upgrade kit installed., and charge you extra the cost of this new core pump, in addition to the cost quoted on this page for the actual upgrade service.
2 – You send us your OEM BMW S54 or S50B32 Euro Oil Pump ahead of time and we perform the upgrade on your pump
3 – Occasionally we have a stock of good reconditioned S54 pumps that we can perform the service to, which is good if you don’t want to buy a brand new pump, please enquire.

PLEASE CALL US TO DISCUSS YOUR REQUIREMENTS.
