Other Benefits of the Boralyn Wrist Pin
Thermal Conductivity: If a steel based alloy is being used the Talbor material can greatly increase the thermal conductivity.
This would lower the temperature around the combustion chamber. The pin would pull heat away from the piston to the
sump environment.The Boralyn would have an estimated CTE of 184.76 W/M K
compared to a Specialty Steel at 26 W/M K. !!!
Wear Properties: Boralyn 20% has 40% less wear than than a good Bearing grade steel.
Coeff of Friction: Our material is 30% lower than a good Bearing grade Steel.
Total Benefits=38 added horsepower@4500rpm,8 cylinder

Weight:
can reduce the weight of most pins by 40%.
This means a wrist pin that weighs 80 grams
can be reduced to 42 grams saving 38 grams of rotating
weight. Actually it would save an additional 38 grams
on the counter balance mass also. Giving a total of 76 grams of
rotating mass savings
