Tremaynes chase the advantage.
Australian innovation could soon be leading the way in the ANDRA Pro Series’ Pro Stock division with Queensland’s Tremayne family developing better ways of making the horsepower needed in the tightest category in Australian motorsport.
Father Kerry and his sons Aaron and Tyronne have produced four Pro Stock championships already but have been working hard to produce their own cylinder heads in the search for an even greater advantage, which they hope to exploit in round three of the championship in Sydney on March 24 and 25.
In a category where hundredths of second is all that separates the entire field, every piece is crucial. The Sydney round may just prove the worth of the engineering.
“We have been building our own engines for some time now but as with most Australian engine builders we rely heavily on American parts especially in cylinder head design and development,” Kerry said. “We decided to do our own thing and we employed Noonan Race Engineering who said they would help us to produce a race winning cylinder head.”
Some of the state of the art features include a superior oiling and cooling system, pushrod location and rocker and valve geometry designed for increased valve train stability, an integrated spring oiling system and many other features.
“Even though there are a few manufacturers in America, their cylinder heads require extensive work to produce the flow figures that ours have off the shelf,” Kerry explained. “The heads will be available in many forms from blank for the engine builder who wants to do his own thing to a CNC-ported set the same as we have on Tyronne’s car at the moment or a complete ready to bolt on package with billet inlet manifold.”
