Yep. Once you reach a certain point in power output, you simply can't remove heat effectively enough with air. The more complex and more powerful engines become, the greater the advantages of liquid cooling. Eventually the engineers at Porsche were faced with a decision: Go to liquid cooling or get left behind by the competition. You can take the latter path and sell on the basis of styling/tradition/mystique for a while, but when the performance gap gets too big you run out of options. -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
