Evolution Of Power
After a short dyno session which will determine the actual peak horsepower that your engine delivers to the wheels(130-140 hp is average). We will remove your exhaust system, from the engine head to the tailpipe tips .We have found large power gains by removing restriction on the
exhaust side .Our stainless steel system starts with an equal length header that blends into a euro-style catalytic converter. This allows the car to be street legal and pass New Jersey (and all other 48 states, except California) annual inspections. Primarily the system gets its power from increase inside pipe diameter, with out a harsh resonance from the twin tailpipes. We recommend our "touring sound" package vs our auto cross mufflers for street use. We have found no significant power advantage by using the louder mufflers but the choice is yours. All stock exhaust hangers and brackets are utilized so the system is easy to maintain and of course its stainless steel for long life.
On the intake side we have experimented with about a dozen different configurations and element types and found a very simple effective method of bringing large volumes of outside (ambient temp), air filtering thru a cleanable K&N type cone filter and sealing this off to prevent high temperature underhood air from entering the intake stream. The importance of this area is obvious and will be even more critical as the power goes up.
Next, still in stage two, is the change in ratio for the crankshaft to supercharger, again we have changed literally dozens of these Eaton supercharger pulleys. We have developed techniques to change these pulleys and belts to raise blower output at the same crankshaft speed. The result is that instead of 9 pounds per square inch of boost pressure ,we are introducing close to 14 psi. Finally stage two includes a computer down load to cope with these increase demands. The installed price includes before/after chassis dyno printouts, all parts and labor above for $3450.The gains in horsepower (typically 25-35 at the wheel!!!) are only overshadowed by the tremendous difference in drivability. These cars absolutely scream on the street or auto cross track.
To top off STAGE THREE is our very unique cylinder head and valve train enhancement. Also developed by our in-house cylinder head specialist on our Superflow flow bench. The gains in mid-range torque is phenomenal. We port match the intake ports to the manifold, cc each combustion chamber for exact compression match, enlarge and reshape each exhaust port individually to equalize flow throughout the head, finally our head wizard does a five angle valve job . This is topped off by our exclusive cam grind. The results on our race engines were impressive, we achieved almost 200 hp at the wheels!!!!! To help breathing we enlarged your throttle body. This will add $3995 to the shopping list, but you will love the results and have one of the fastest street Mini's in existence. We believe that for a total investment of $7450 you will have double the horsepower increase that the JCW kits gives you for $6800.
We developed our Stage Three directly from our racing experience. We found with the Mini, as with other supercharged applications that the increase in boost pressure, brings with it an increase in intake air temperature. Its a matter of physics, that I am not getting into the full explanation here but, it happens, and the tiny intercooler, located horizontally on top of the motor is too small and heat soaks rapidly. It needs high air speed (i.e., fast mph) to work and it dumps what little heat it manages to remove from the intake charge directly on top of the fuel injectors, fuel rail, intake manifold and supercharger!!! If you have concluded by now that this is a losing proposition, you're right. On the race cars we built massive air to air intercoolers and mounted them directly in the air stream in front of the radiator, behind the grille in front of the hood. This worked, but is not practical for street Mini's as it requires removal of the air conditioning system.
But don't despair, a water cooled intercooler is now here! The system has its own pump hoses and heat exchanger completely separate from the vehicles cooling system. It cools the super heated intake charge to pack more air into the combustion chamber. This is a must for road racing and all applications that require repeated high boost conditions.
