NOW INTRODUCING RJS STAGE I AND STAGE II BILLIT CNC BLOWERS
Our exclusive design operates at a lower rpm to achieve maximum boost levels and extended bearing life.
Stage I - 1L to 4L engines
Stage II - 5L engines and up
New for 1000cc engines and smaller, we offer the PDB, a positive displacement (Judson Design) blower that operates 6psi at idle. It is easy to install and runs off the stock belt system. Your small engine can achieve up to 40% more hp and torque.
BENEFITS OF AN RJS SUPERCHARGER
-
Improved horsepower and torque. RJS units are set up for 6 lbs. of boost for stock engines. A 40/50% horsepower and torque gain
-
RJS Superchargers requires fewer engine modifications when compared to other superchargers and turbocharger systems. A simple bolt on installation
-
Lower cost to install than a typical supercharger and turbocharger system
-
Runs cool air through the intake manifold unlike turbos which run hot exhaust air
-
Supercharger's boost occurs at lower RPM ranges providing better driveability versus turbochargers which need time to spool up to provide boost
-
Better reliability
RJS SUPERCHARGERS units can be modified to fit all import, domestic, diesel and propane motors used for off-road racing, 4- wheeling, sandrails, dune buggy, drag racing, drifting, motorhomes, tractors, towing applications and other closed-circuit applications.

1.6L SOHC Stock Engine HP = 70 / Supercharged Engine HP = 102
800CC SOHC Stock Engine HP = 18 / Supercharged Engine HP = 42
2.2L SOHC Stock Engine HP = 92 / Supercharged Engine HP = 128
350CI SOHC Stock Engine HP= 289 / Supercharged Engine HP= 360
These results are actual rear-wheel horsepower at only 6psi of boost. Engine results may vary.
