Supercharger for 450-500whp out of a 2015 5.3L - Price vs gains
 

I'm probably going to put a blower on my 2015 Sierra Crew... The truck is used as a DD and occasionally tows my camaro to the track (5500lbs max) - I'd like to do a supercharger and while I'd love a PD blower, I've driven vehicles with a centri before and like those just fine too. Some info about the truck...

It's a 5.3L with a 6AT - 35k on it - currently stock. Not planning on many mods besides the supercharger itself. I'd like to keep the truck to a stock-ish volume level as the wife drives it now and then - This means I might do a secondary cat delete, but the headers and cat-back will probably stay stock (at most I'd upgrade to the bigger 6.2L rear section).

I will do ported a LT1 TB and Intake mani if I do a centri - because my '17 Camaro has them and I'm replacing them with an MSD/103TB so they're "free mods" from the Camaro.

I will be using 92 octane exclusively and the truck will get a custom dyno tune (and trans tune too)

What blower will get me to 450-500whp with the above mods for the least money?

I see a lot of list prices in the $5500-6500 ballpark and I know basically every manufacturer has MAP (minimum advertised pricing) restrictions so I'm curious to hear what people are *really* paying for these things... Would love to keep it closer to $5k but unsure how realistic that is.
