On that point, you're totally right, but...
I live in europe, and if our gas is not as cheap as yours (count around 12$ a gallon)
We do have the advantage to run better gas than north america.
On pump gas 95 as the lowest and 98.
Also, I do have an kit or water/ethanol injection,
Obviously, the water is to cool it down. But with an
Ratio around 70% water and 30% methanol, the octane
Is suppose to climb around 104/105
Also, an roots supercharger does pump a lot of hp, where the procharger
Is less gluttony in power (also thanks to the centrifugal acceleration square root of the
Power)
So, in the end, it's a lot less advantageous at low RPM than a roots, but a
Lot more advantageous at mid and high range!
