AMS Performance:

The Alpha Performance Audi C7 S6/S7 Boost Cooler System consistently lowers intake temperatures, eliminating the heat soak that robs your Audi S6/S7 of horsepower. It features a premium quality, triple pass heat exchanger, an extra large coolant reservoir, and a brushless coolant pump to maximize flow rate throughout the system. The result is a cooler intake charge that improves acceleration, power and consistency while allowing your Audi S6 or S7 to operate safely no matter how hot the climate or how long you drive for!

As with all Alpha Products, everything needed to install the system is included – bolts, fittings, lines etc. Best of all, no drilling or modifications to the car are required, it’s a 100% bolt in affair.

Hard 'Core'

The most important part of boost cooler system is the heat exchanger core. Skimping here could mean the overall performance of an ‘upgraded’ system might be worse than stock!  While the OEM unit is a single pass design with a core area of 156in, Alpha core is a high quality, triple pass unit in which the coolant makes three passes through the heat exchanger - compare this to competing boost cooling kits which use a single pass design.  Alpha's premium core is made in the UK with a fin area of 417in^2. That’s almost three times the surface area of the stock core!  For added durability, the fins are hemmed, giving it the added strength to withstand abuse from road debris.

Increased Coolant Capacity, Decreased Heat Soak

The hand-fabricated Alpha coolant reservoir acts as a large heat sink so that coolant temperatures are kept low and stable. With over one gallon more coolant on board, it increases the cycle time of the coolant in your S6/S7, allowing more heat to dissipate before recirculating back into the system. By acting as a large thermal heat sink, the Alpha coolant reservoir is yet another feature that keeps horsepower-killing heat soak at bay.

Pumping Up the Power!

To give you the best possible performance and keep the coolant flowing efficiently through the larger Alpha heat exchanger, we added an additional high flow brushless pump to run in conjunction with the OEM brushless pump.  The combination of the two pumps allow a very high flow rate to keep the fluid moving and maintains that flow rate at higher pressures giving you the assurance your car will stay cool in hot climates, extended track sessions or everyday driving. See graph below for pump data.

The Devil is in the Details:

To provide your S6/S7 with the best boost cooling system on the market, we thoroughly tested multiple variations of the Alpha Boost Cooler System. We tested divorced and non-divorced systems and found that divorcing the system provided no real gains, only added complexity. After discovering that the stock pump flow rate diminishes drastically after 8psi, we added an additional brushless pump to support the higher pressure needed to maintain flow. Data log after data log was recorded and the results were analyzed until Alpha Performances' engineers were completely satisfied.

All testing/logging was performed on Alpha's Dynojet dynamometer doing 1st through 5th gear pulls with conditions and ambient air temps being equal.

Post Intercooler Air Temperature:

This graph shows the difference between stock VS Alpha air temperatures after the air has passed through the intercooler, cooler air means more horsepower!

Post Intercooler Coolant Temperature:

The graph below shows the difference between stock vs Alpha air temperatures after the air has passed through the intercooler. Cooler air temp means more horsepower!

Pre Intercooler Coolant Temperature:

This graph shows the ability of the Alpha system to pull more heat out of the cooling system. Notice how the water temps stay more consistent with the Alpha Cooler.  If the heat rejection was the same between the stock and Alpha system, the lines would trend the same.
