XTREME SERIES SC IMPELLER
Engine-Tech Xtreme series supercharger impeller
from Race Tech for Yamaha 1.8 liter supercharged
engines. This billet aluminum impeller was computer
designed for maximum efficiency and produced on a
5 axis CNC center. It then gets computer balanced and anodized for corrosion
resistance. Every gram of excess weight was shaved from this impeller to
make it the lightest impeller on the market without sacrificing strength. It is a
full 17% lighter than the stock impeller for better clutch and shaft life. This
impeller can produce up to an astonishing 16+ lbs of boost !
Must be used with adjustable fuel regulator, high flow intercooler and ECU
(Motec or equiv, Motec map available upon request)

SUPERCHARGER IMPELLER
This is a drop in impeller so no modifications to the
housings are necessary. Weighing a mere 106
grams this is the lightest impeller on the market
reducing wear and tear on the clutch/shaft assembly. Output is 15+ psi
@7700 rpm and an amazing 18+psi @8500 rpm.

SILICONE INTAKE HOSE KIT
The R&D Yamaha FX-SHO/FZR/FZS Supercharger
High Performance Hose Kit was developed while testing the R&D Monster
Compressor Wheel Kits. Higher boost pressures create higher intake air
temperatures of up to 235 degrees. The O.E.M. standard black rubber hose
and standard hose clamps just do not hold up to the pressures and heat like
high quality, high temperature silicone hose and high strength stainless steel
T-bolt style hose clamps. The R&D “Blue Hose” is manufactured from high
performance, turbo charger quality high-temperature silicone. The R&D
silicone hose installs easily in place of the OEM rubber elbow hose, and
T-bolt clamps will keep the hose secure for the longest of endurance races.

R&D's new High Performance Billet
Supercharger Shaft eliminates the weak design features of the OEM and after-
market HKS supercharger shafts. After analyzing the OEM HKS shaft design
and sorting through the various failures we had with it while testing our popular
Monster S/C Wheels, we developed a superior shaft design. The new R&D
shaft is not a copy of the fragile HKS design. Rather, it is a completely new
design, superior in material strength and improved in every way. The new R&D
Shaft is precision CNC machined, heat treated, and precision ground from bil-
let steel alloy. Featuring a uni-structure design that incorporates the shaft and
gear as one billet piece, much like a transmission shaft. This eliminates the
fracture point on the OEM design where the gear shears off the end of the
shaft. The billet design will not allow the gear to slip under high boost loads
like the pressed on OEM gear.
Next R&D increased the inadequate 6mm thread diameter on the OEM shaft
to utilize a well proven “Turbo spec” LARGER 5/16-24 left handed thread that
will not break under extreme conditions. The larger thread diameter will also
allow wheel torque specs to be increased safely.
Lastly, R&D reduced the weight of the R&D Supercharger shaft by eliminating
the hex nut on rear the gear and lightened the end of the shaft/gear inside
diameter to significantly reduce reciprocating weight. We all know what that
will do to add to clutch performance. Kit comes complete with larger nut and
installation instructions. All in all, the new R&D High Performance Billet Racing
Shaft is not just a replacement shaft, but a solution to end all supercharger
shaft problems.

BEARING/SEAL KITS &
DUPLEX BEARING KIT
R&D offers an answer to both repairing & upgrading the O.E.M. superchargers
vulnerable thrust bearing and main shaft bearing assemblies. Engines with
superchargers running higher boost pressures and higher rpm frequencies will
eventually need bearing servicing. Servicing the supercharger main bearings
periodically or upgrading to R&D’s new “Duplex Bearing System” will extend
the life of the superchargers thrust bearing significantly. R&D offers both stan-
dard replacement bearing kits, and the new “Duplex Bearing Kit” that will work
in any Yamaha supercharger. R&D also offers complete rebuild kits for stock
superchargers running C1 Monster Wheel Kits and all supercharger wheel kits
using the stock exducer size. R&D also offers rebuild kits for all C3, C5, C7
Monster Wheel Kits with larger exducers.
