Im looking into a Supercharger instead of a turbo for the next sled I wish to purchace. The Supercharger because there is no lag.
Here's what I found, Mountain Performance Stage 1 Kit:
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.
