R&D/Tial 50mm BOV Surge Protector Valve only Sea Doo 613-95263
R&D now offers the Ultimate Sea-Doo Surge Protector Kit. The new
R&D/Tial 50mm kit works in the same fashion as our entry level surge kit,
except its flow capacity is greatly increased. The 50mm diameter with its 6
exit port design releases compressor surge much quicker and more
efficiently than any other system available. This means less wear and stress
on the supercharger clutch. Compressor surge is defined as the negative
charge of pressure that causes turbulence in the supercharger that occurs
during aggressive of off-throttle operations. When the throttle valve is abruptly
closed at high rpms, the engine decelerates quickly down from 8,000 rpms,
however the supercharger is compressing air (creating boost) as the supercharger
has to decelerate from 42,000 rpms. This turbulence is the primary
cause of undue stress on the supercharger clutch system and its
components. The R&D surge protection kit utilizes an automotive vacuum
assisted pressure blow off valve that automatically releases the unwanted
intake pressure between the closed throttle valve and the supercharger. As
soon as the throttle valve is opened, the blow off valve immediately closes
and the compressor can supply its full boost potentials to the engine.
The R&D kit installs into the OEM intake hose, but for optimum performance,
use the R&D Straight Shot Intake Hose (Pt. #613-95257). This kit is a very
necessary and cost effective up-grade for all Sea-Doo supercharged
watercraft. Kit comes complete with mounting hardware and instructions.
For easy vacuum line hook-up use R&D Multi-Port Adaptor (Pt. #613-95270).
