One of the most common questions we get everyday from Cooper "S" owners is, "what can I do to make my MINI faster and which performance modification should I do first?

Here is my reply. Assuming that your vehicle is showroom stock there are two areas where your car can see the most benefit as far as performance upgrades. These include the intake system and the exhaust system. The modifications that I'm about to recommend are relatively inexpensive, when comparing them to the more serious modifications, that require engine disassembly.

Intake system: Cheap & easy horse power!

The most popular and biggest bang for your Buck is a PROMINI free flow "Racing Filter Kit". This modification can be performed by the average car enthusiast in about 30 minutes. The end result will be a gain of approximately 10 to 12 H.P. The magic behind this upgrade is simple. The less restriction to the supercharger on inlet side, the more the supercharger can compress the air on the engine side. The result is a boost increase of 1.5 P.S.I. The Dyno result is an increase of approximately 12.5 H.P. The results are plain and simple and the Dyno Chart will show you the results. For more info click here.

Supercharger Pulley

20 H.P. for only $139.95 Smaller Supercharger pulley: The magic here is real simple. Reducing the size of the Supercharger pulley increases the Supercharger R.P.M. End result, the faster you turn the Blower, the more you increase the boost. PROMINI offers pulley's in three upgrade sizes 15%, 17%, 19%. Our pulleys are C.N.C. machined collet style pulleys, they do not require a press fit. All three require the same install time. Naturally the 19% pulley offers the highest H.P. and torque improvement. Expect a 20 H.P. gain.

Installation is recommended to be performed by a professional. Allow approximately 3.5 hours installation time. For more info click here.

Performance Exhaust system

This area is easy to over look, once you have done both of the above. However you need to keep in mind, that the more air you put in the engine, the more exhaust that needs to escape. This increase in exhaust volume also increases back pressure and heat. Adding a Free flow Supersprint exhaust system will allow you to maximize your performance gains. The great feature with a Supersprint system is that you have the option to add the larger diameter connecting pipe at any time. If at some point in time you decide to increase performance to over 225 H.P. Another big advantage is the Supersprint street system has a deep sporty sound without violating any sound emission requirements.For more info click here.
