INTERCOOLER
COOLING KIT
The R&D Yamaha FX-
SHO/FZR/FZS Intercooler
Temperature Control sys-
tem was developed to offer
an inexpensive complete
bolt on kit that will allow the
full performance and cooling potential the O.E.M. intercooler has to offer for
recreational applications. Intercooler core water temperatures have a range of
affect on the supercharged air temperatures that enter into the engine. The
Yamaha SHO Intercooler operates on a single low pressure (10 P.S.I.) line of
lake temperature water to cool the intercooler. R&D has found that by adding
an additional intercooler water in line, and adding an additional water out line
and bypass fitting, there will be double the water flow volume at 20 P.S.I.
Reduced intercooler core temperatures can add a noticeable increase in
low end and midrange power along with reduced detonation. R&D offers a
range of machined flow control fittings to allow water volume control tuning for
intercooler temperature adjustments for warm lake water and extreme hot air
conditions. R&D also offers a pressure relief blowoff valve kit for high water
volume flow rates on higher boost Stage 1 and up engine kits. The R&D Kit
will allow temperature tuning that will deliver surprising results. Unlock hidden
performance and power potential in the OEM stock intercooler or aftermarket
intercooler system by reducing intercooler core temperatures.
• More horsepower with cooler intake air temperatures
• Increased acceleration and mid range performance
• Reduces detonation in hot weather conditions
• Temperature control tuneability
• An inexpensive recreational performance addition
• Pressure relief valve options
• Easy installation instruction

COOLING KIT
The R&D Yamaha
SHO/FZR
Engine/Intercooler
Cooling Kit was devel-
oped for high performance recreational and racing use. Extensive engine
cooling and inlet air temperature testing using both MoTeC I2 and Innovate
digital logging systems has proven the R&D High Performance Cooling Kit to
offer double the water volume flow through the engine, oil cooler, and inter-
cooler as well as increase water pressure. The O.E.M. cooling system has a
very low water pressure (10 P.S.I. at 7600 rpm’s) and a low water volume
flow. The new R&D kit will double the water volume which will lower intake air
temperature by 15-20 degrees as well as lower engine block and head tem-
peratures by 40-50 degrees. The additional oil cooler water line will lower
engine oil temperatures by 15-20 degrees promoting better lubrication and
increased engine cooling. The R&D Cooling Kit arrives 100 percent complete
with pre-cut hoses, “T” connectors, dual line pump block, through hull bulk-
head fittings, hose clamps, water by-pass fittings, the thermostat removal
sealing washer, and detailed instructions with pictures. R&D recommends the
cooling system to be upgraded as a stand alone performance upgrade and a
must have kit addition when installing power adders such as R&D
Supercharger Wheels, Engine Performance Parts, and Engine Management
Kit parts. Cooler engine, inlet air, and oil temperatures produce higher horse-
power with decrease detonation
*Better throttle response, increased horsepower
*Cooler header and under seat temperatures
*Increased power with cooler air inlet temperatures
*Cooler cylinder and cylinder head will reduce knock
*Cooler oil will lubricate better and last longer
*Increased engine protection
*Improved clutch performance with cooler oil

RIVA ENGINE BREATHER UPGRADE KIT
Easy to install Engine Breather Upgrade Kit
eliminates power-robbing crankcase emissions from your engine's air intake.
Increases horsepower by removing the engine's requirement to burn relatively
non-combustible oil. Also improves intercooler efficiency by preventing the oil
sludge coating that lowers
thermal efficiency. Easy installation retains highly efficient OEM air/oil separator
system. Kit includes pre-formed hose with attached K&N filter along with all
necessary hardware & instructions.
