I've yet to run into anyone that is limited to ~6 psi, say they actually WANT less than 6 psi. They all want 8 psi lol. Not daydreamers, but guys with actual boost on their car. It's human nature.
But I've only been doing this ~20 years, so maybe they are out there.
My first supercharger was the old ball drive paxton. Made 5 psi., and I wanted every single bit of it lol.
I bet that say you got the controls down, and the blower was capable of 4 psi at bottom, 2 psi at top, and you spent hundreds of extra dollars on limiting boost, 99% of guys would just end up running it full on anyway. Once you drive it, you will understand.
This control stuff would be cool if this thing could make 20 psi, then you can tailor a boost curve to deliver a cylinder pressure curve that the motor would be happy with....
So the control is actually the very very easy part. Even if it was a simple open loop duty cycle table with rpm and tps or mph as the axis. There are ecu boost control devices on the market that can be mapped on a laptop to do it, for like $250.
The hard part is generating enough boost to where someone would actually want it tapered down. ie, the mechanical and electrical parts.
