SEA-DOO 4-STROKE • SUPERCHARGER
SEA-DOO 255/260
C3 MONSTER CHARGER WHEEL
More Boost and Horsepower is on its way with the new R&D Monster Power
Supercharger Impeller Wheel Kits. The R&D engineering staff has been
developing a complete line of supercharger impeller wheels that actually
deliver the power and boost pressures we promise. Each Monster Impeller
wheel will come complete with a statistical data sheet graphing the
RPM/boost pressures that the wheel produces, eliminating the mystery
behind the supercharger.
B
alancing Information:
R&D Monster Compressor Wheels for 255 H.P. 4 Tec engines have been
precision mass center balanced in the preliminary casting/machining
operations process, and precision two plane balanced after the final
machining processes. The balance tolerances on the R&D Monster Wheels
are held to a much stricter and tighter tolerance over O.E.M. or aftermarket
wheels. Your R&D compressor wheel may have small balancing grooves
machined in the blade channels of the wheel in some areas. This procedure
is part of the mass center balancing process. The small grooves do not in any
way impede or hinder the compressor wheels ability to efficiently pump or
compress air. The R&D precision two plane balanced compressor wheels will
perform perfectly and smoothly at 180,000-200,000 rpm’s as the wheels have
been blueprinted and balanced to stringent turbocharger specifications, even
though the wheel will only spin at 46-48,000 rpm’s in the Rotax engine at
8,000 crankshaft rpm’s. R&D has gone the extra mile in the balancing
process of the Monster Wheels as higher balancing standards will add
significantly to the service life and performance of Rotax’s vulnerable and
temperamental clutch system. Precision balancing will significantly increase
bearing life, promote better clutch performance, extend clutch life through
decreased clutch slippage, and increase horsepower performance.
