Yup supercharging is hard to beat on the street.
You will come to the limit of retarding the timing-adding boost on pump gas. To avoid knock with more boost.
When it knocks , when at high boost, that knock is much more severe. You don't get as second chance.
It comes unglued real quick, when you exceed the laws of physics.
You going to find the limits of 91 octane gas real soon.
Mounting the spark box that close to the engine is not good. (heat)
The power gain by adding more boost/pulley drive ratio is not linear.
Any gains per # of boost from this point will be much smaller. Reliability goes way down.
Detonation will cut apart a expensive engine just as fast as a cheap engine.
Time to get water meth injection.
