Boost guesses on my whipple setup

Here ya go, have at it. Keep in I basically made up the VE and intercooler efficiencies so that has some bearing on it. The supercharger power required is just based on the aerodynamic load, the real number will be higher due parasitic losses but I dont have a good way to calculate that, so just add like 20% if you want a number.
Also keep in mind I have like 4 different boost gauges for various reasons, and they all read different. So just because the spreadsheet doesnt match your gauge doesnt mean either is wrong. This is just meant to get you in the ballpark.

Thanks Richard, I’d be happy around 11-12 psi if that’s what it runs when it’s all put together. Ultimately I’d like to run 12 psi so if I have to down pulley from the 3” when it’s all going so be it.
thanks for the info

As a complete novice, trying to use the spreadsheet but unable to determine crank diameter. This is for a 5.3 (LC9) engine, but trying to determine what the spreadsheet is actually calculating, not just searching for a number to plug in.
TIA!
