Cylinder Heads

Pat Downs is known worldwide for his cylinder head knowledge. Since 1986, Pat has developed or been a part of developing multiple VW cylinder heads. These cylinder heads have set records in many racing sanctions including the ECPRA where Pat holds the current Pro Stock E.T record @5.90 seconds.

The biggest challenge on a VW engine is selecting the appropriate cylinder head for the intended use of the car. Port flow, port velocity, and cooling capability all come into play when selecting the correct cylinder head. With Pat’s knowledge of port design, he can help customers make the correct decision on the appropriate cylinder head for their engine.
