Now is it because the SC is capped @ 8psi that it can't achieve higher numbers or is it some VVEL thing holding it back?
Sorry, not trying to stir the pot just trying to wrap my head around this.
Thanks

The Supercharger Unit itself is not capped at 8psi...our Stage 1.5 Supercharger Kit proves that.
The Stage 1 Supercharger as it was originally designed, needs a little bit of back-pressure from the exhaust to keep the compressor in its efficiency range. Once the exhaust back pressure is reduced too much, the compressor loses efficiency and therefore, makes less power.
If you are looking for more power than the Stage 1, but still want good mid-range torque, then check out the Stage 1.5:
