Nytro, Phazer, Apex, RX-1,
 & Vector Supercharger Kits

Stage I Performance:

Stage I kits are intended for a maximum of 11 PSI (slightly less at extreme altitudes over 10,000 ft). At 10 to 11 PSI we recommend all models use a 50/50 mix of Premium Gas (92+ R+M/2 Octane) and  Race Gas (110+ Motor Octane) - or better yet 100% race gas. Kits can be run at 5-7lbs of boost (recommend 5psi at sea level). Each pound of boost is equal to approximately a 10HP increase, so when decreasing boost to run pump gas, you can apply that information to determine HP. Stage 1 Nytro produces 220HP at 11PSI. The Phazer kit ships at 140HP at 11pounds of boost. The Apex is shipping at 240+HP at 10 pounds of boost. The RX-1 boasts a consumer friendly 230+HP also at 10 pounds of boost. Vector Stage I is well in excess of 200HP at just over 10 pounds of boost. For those desiring more power, numbers in excess of 270 to 350+HP is coming on Stage II and Stage III.

Stage II Performance:

Stage II horsepower is limited only by the OEM motor durability and the OEM fuel system on EFI models. With stage II at sea level we recommend the installation of 10:1 pistons for any Stage 2 mod. We recommend 100% race gas, but a 50/50 mix of Premium Gas (92+ Octane) and  Race Gas (110+ Octane) is acceptable up to 14 PSI. At high altitude (over 6000ft it is recommended that you run stock pistons up to 14PSI). EFI models require a fuel system upgrade to run beyond 14PSI of boost. Therefore, we offer 2 types of Stage II kits, Stage 2A & Stage 2B. Stage 2A does not require fuel system mods, while stage 2B kits include an upgraded fuel management system including a new pump and a patented closed loop electronic fuel pressure control system. Stage 2B kits are not recommended for altitudes in excess of 6000 ft, at the Stage II supercharger only produces about 14PSI at extreme altitudes. High altitude customers should consider Stage III kits for more power than Stage 2A.  Stage 2A Apex is shipping at 280HP and the stage 2 RX-1 just slightly less at 270HP. 

Stage III Performance:

Stage III Kits are the same as Stage II, with the addition of an upgraded fuel management system including a new pump and a patented closed loop electronic fuel pressure control system plus a larger supercharger. We recommend pistons, studs & rods when the motor is upgraded to Stage III. Stage III is capable of over 350HP. Call for details. 

Highlights:

This kit was designed by a team of experienced engineers with 4 specific goals in mind:

1. Easy Install - No drilling, cutting or fabricating required. Consumer installs pre-assembled sub systems. Typical 5hr install plus clutch changes. 

2. Dependable HP - Build on the awesome reliability of the Yamaha based R1 Motor.

3. Instantaneous Throttle Response - MPI knows this is required for an A+ fun factor.

4. Repeatable Performance - The system must not require "tinkering" to make it run.

We have met and exceeded our design goals in all aspects. Each of the key factors mentioned have met the requirements of the most discriminating enthusiasts.
