The Supercharger is a more sophisticated alternative to the well-known turbocharger. The advantage in relation to the turbocharger is that you get no "delay" because the Supercharger shows its power at once. With the Supercharger you get a far more cultivated and controlled power development, with smooth power and flexibility as the key word.
The ESS Supercharger systems has been developed to meet the demands of today's motorists and the increasingly stringent requirements concerning environmental emissions.
The objective established by ESS at the start of our product development was to create systems designed consistent with the most modern concepts of automotive supercharging. We felt it necessary to create a design that would have virtually zero affect on long term durability, yet offer the high level of power and finesse demanded by the serious enthusiast.
Our systems brings together the engineering and hardware into one complete package. The net result is a very quick car with no sacrifice in daily utility. All the wonderful driving characteristics of the stock vehicle are retained with the addition of the ESS Supercharger. We feel it is a system above reproach for specification, quality of manufacture, and above all, function.
The singular most critical element regarding power and safety of any forced induction system is the maintenance of correct air/fuel ratios when operating under boost. Lean mixtures promote heat and heat leads to engine detonation. The method employed for keeping the air/fuel proportioning absolutely correct is to redesign the factory engine control system software and using larger fuel injectors. This is the most advanced method and also the approach which is most difficult in means of software programming and testing. But the end result is total fuel/ignition control at all RPM and load conditions, meaning greater power, minimal fuel consumption and maxiumum engine safety.
The exitement of driving is clearly the purpose behind any supercharging exercise. If one truly finds the stock car exiting to drive, imagine what exitement awaits you when the performance ante is substantially raised.
The substantial increase in engine power does not come about at the expense of the sweet driving nature of your high-end car. All aspects of smooth, easy driveability are controlled by such factors as fuel injection calibration, compression ratio, camshaft profiles, and ignition timing. These items are unaltered in the installation when not operating under boost, therefore the driveability is also unchanged from stock.
No time delay exists between moving the throttle and boost pressure response. When motoring along, the boost response is as fast as you move your foot.
Clearly, one of our objectives was to create a beautiful installation and to have it stay that way. We firmly believe you will be as proud to show this assembly to your friends or customers as we are to present it to you.
Engine safety and long term durability are almost solely the result of thermal load and detonation control. It is here that the real benefits of the highly efficient ESS Supercharger systems step to the forefront. The only other factors are quality of maintenance and the percentage of time the engine spends running at its redline RPM. Oddly enough, power has little relevance to durability. A full explanation of that statement lies in the mathematical and dynamic analysis of the power loads versus the inertial loads. A discussion of such length is impractical to include here, but revealing of the very interesting circumstance that the engine's component loads due to inertia loading will always subtract from the power load.
This permits the odd situation of actually doubling an engine's power output, but not doubling the loads it must endure. That interesting characteristic of the piston engine was the key to enormous power outputs of the turbocharged Grand Prix cars of the mid/late 1980's. They achieved power levels in excess of 1,300 BHP for qualifying and raced at around 900 BHP, all from engines slightly smaller than 2 litre. Please accept as fact, without showing the actual calculations, a 500 BHP power loading from your BMW M3 engine at its stock RPM ranges will not even tickle its structural tummy. As explained earlier, thermal loads are the killer. In that respect we urge you look closely at the safety features that are standard equipment with the ESS system.
Service and Maintenance With the ESS Supercharger system, once installed and detailed nicely, the owner/driver can expect to close the bonnet and forget it.
Warranty: All items of our system carry a two year / unlimited mileage warranty. Our standard system warranty does not extend to any stock components. The vehicle manufacturer will not warrant engine or drive line items damaged by the supercharger installation.
Fuel requirements: Octane rating is the key item, and it is very important to use nothing less than 91 US octane (95 Euro).
