TorqStorm Supercharger build advice needed

So, let me run a different scenario. I hat if he built a 9 to 9.5:1 engine, decent cam and Holley Sniper. Power wise how would that compare to a 8:1 engine running 6 pounds of boost? Just curious as I’m trying to keep the cab of worms we have to open to only a medium sized can LOL
A 9:1 slant will be down 70-100 hp over a 8:1 slant on 6-8 psi.

Lots of over thinking goin on. Build a slant, put on blower, put on sniper, pump it full of 91 octane, hit gas, smile ear to ear.
