GRS R53 Top Mount Intercooler Upgrade for MINI - Motorsport Version
The GRS Intercooler is a high performance upgrade over the standard MINI intercooler. This intercooler will reduce intake temperatures and improve the BHP of your R53 MINI Cooper S or JCW.
Featuring a large surface area and core thickness, which increases performance over a standard MINI intercooler, after upgrading to a reduced supercharger pulley an efficient intercooler becomes even more important as airflow is increased which means more air has to be cooled. The GRS intercooler is a quality piece of engineering and has been tested to 100 psi, a precision cut fiberglass and carbon fiber diffuser is included to improve airflow over the intercooler, which can only be found on the GRS.
The end tanks have been specially designed to insure a ‘ram air effect’ is achieved through the core to achieve maximum cooling. ‘Boxed end tanks’ with sharp edges do not work as well as ‘Tapered end tanks’ as the charged air can become very lazy. GRS have carefully selected the right ‘tube’ & ‘vain pitch’ to ensure the core is right for this type of top mounted intercooler. The standard Intercooler on the Mini Cooper S will only keep air charge temperatures (ACT’s) down to a satisfactory level with boost levels of no more than around 8-9psi. Once the boost pressures have been increased the ACT’s associated with the higher boost levels can be excessive for a standard intercooler. As ACT's rise, power is lost due to the air containing less oxygen. The GRS Intercooler has been designed to keep the ACT's to a satisfactory level. GRS say when the intercooler was tested on a rolling road it showed no more than 38 degrees at all times, at 13-14psi, thus ensuring that maximum power is always available even in hot weather.
GRS Motorsport Version
The ‘Motorsport’ version has a diverter welded between the end tanks, this helps spread the air from the bonnet scoop evenly over the core, this design has shown a noticeable improvement in the cooling capabilities over the standard GRS Intercooler. Testing showed a 5bhp increase over the normal GRS intercooler, a GRS customer in Italy using a rolling road carried out tests.

Q. Can I fit Alta intercooler couplers with the GRS intercooler?
A. Unfortunately not. The end tanks on the intercooler are too large.

Lohen offers in-house fitting for all products at our workshop in Eccleshall, Staffordshire. Here are the things you need to know:
Fitting Cost - £60
Fitting Time - 1 Hour
Required Additional Items/Services - No additional items or services needed.
Lohen Recommends - When installing a uprated Intercooler you can now purchase a 17% pulley as your engine will be able to handle the increased temperatures and your ECU will not pull the power back.
