Why it�s important to keep the pin spinning: In each firing cycle the piston pin carries the weight

By Titus Bloom, October 13, 2014

engine progress follows a basic pattern: As power increases, problems
emerge and as the ingenuity of the race engineer solves them other
problems appear. Race engines operate in a state of perpetual
crisis. In the 1970s Top Fuel cars generated 2,500 to 3,000hp today they
make 8,000 to 10,000hp. To get from 2,500 to 10,000hp a lot of problems
needed solutions.

Trend Performance introduced its tool steel TP-1 piston pin in early
2013, first to drag racing’s Top Fuel teams and subsequently to all
other engine categories generating big power, it possessed several
attributes that weren’t easily copied.

people don’t realize that during the firing cycle of one cylinder the
piston pin carries the weight-the mass and…
