For those who want even more from their VW 8 valve engine, we went a little further. This is our big valve head. Bigger valves mean more flow. More flow means more power. Our expertise in achieveing huge gas flow increases means even more power. Check out the images above for an idea of the superb engineering that goes in to this head. This head shows a mighty 45.6% increase in inlet flow and 31.3% increase in exhaust flow. By any measure these are substantial increase.
Note : flow diagrams show flow against specific valve openings at 0.050 inch valve openings at 10″ pressure. Therefore actual flow volume increase is measured as the area under the graph (indicated in yellow for inlet and blue for exhaust). Standard valve sizes are used on our heads unless specified as a big valve version. Tests shown here are carried out on a flow bench on a bare head without filters. Therefore the difference between a standard engine with standard inlet ducting and filters will be larger than shown here.
