Putting a larger displacement compressor on a vehicle rarely makes it perform better and in some cases it can actually decrease performance. Most systems are designed for specific performance goals. These goals are determined by a number of factors: glass area, interior space, projected heat load, engine operating RPM, just to name a few. After all these factors have been calculated, the heat exchangers are designed for a specific BTU range. The compressor is then selected for the application.
By choosing components that have the same BTU ratings, you achieve what is known as a Ã¢ÂÂBalanced SystemÃ¢ÂÂ. Using a larger compressor without Ã¢ÂÂBalancing the SystemÃ¢ÂÂ can result in a 15% (or more) loss of cooling. This will also cause early compressor failure.
