Sleeve
BRB –
Special Bronze Alloy
Parts made
out of this alloy are high heat resistant, have very low heat
expansion rate, and does not change original geometry under
high heat. BRB is an alloy which has mechanical properties of
spring type steel.
Sleeves
made out of BRB do not "balloon" in top dead center area over
time.
Piston
Palmaris
Racing piston is an aluminum alloy containing 27% silicon
which makes piston lighter and a lot less friction. It helps
keep original geometry under high temperatures.
Connecting
Rod
Palmaris
Racing connecting rods are made out of super strong aluminum
alloy. The bushings in the rods are made out bronze which were
developed in the aerospace industry for high heat and high RPM
applications.
Crankshaft
Palmaris
Racing crankshafts are made out of steel which gave us the
possibility for surface hardening upto 62 points of rockwell
scale. In the mean time, main body of crankshaft is not
brittle. Palmaris Racings uses high technology balancing in
all of its Crankshafts.
Bi-Metal
Sleeve
The
Palmaris Racing bi-metal sleeve is an absolutly new
development in any nitro engine application. by using
bi-metal technology, we are able to provide better control of
expansion by the length of the sleeve. Fusions of two metals
together is a high tech welding technology developed by world
famous Profi. This welding is able to withstand high
vibration, high pressure, and high temperature while
maintaining original geometry.
All parts
are made on CNC machines with very high tolerances quality
control. every single piston / Liner set is individually
fitted to the best possible fitting. Due to the materials and
technology Palmaris Racing uses, our parts require minimum run
in period, which saves a lot of time and fuel for the racers.
To design all our products,
we are using state of the art CAD and simulation software's.
