HP Performance's Quarter Mile Cooler Install

The Quarter-Mile Cooler was originally designed for an SN-95 car, but keeping the same size allows a single part number to fit all late-model Mustang applications from 1979 to present.

The cooler features a drain valve for when you're not at the track, or for between rounds when you need to drain the warmed water for a batch of fresh, icy H2O.

You'll need to make three holes in the spare tire well for the feed, return, and drain lines. Even though grommets are recommended to protect the lines, you should silicone them for added protection. The water pump, which is a Bosch piece from the Lightning parts bin, is mounted back by the tank.

The feed and return lines, along with the power leads for the water pump, are routed up to the engine compartment.

The Kenne Bell heat exchanger is used to pull heat from the intercooler coolant.

Our test subject retained the Kenne Bell fluid reservoir for increased capacity.

A 50/50 coolant mix is recommended, though ice water can be substituted at the track or in areas where freezing ambient temperatures aren't a problem.

With the factory trunk mat back in place, the Quarter-mile Cooler is out of sight.

With the cooler intake charge temperatures, we were able to add 3 psi of boost through a pulley change on the Kenne Bell supercharger, resulting in a gain of 36 rwhp and 43 lb-ft of torque. Anytime you can pick up gains under the entire curve as we did, it will provide more seat-of-the-pants results, as well as decreased elapsed times greater than if you'd picked up just at peak power.
