It'll probably be early next year and probably considerably less expensive than $40K and IMO will make a tad over 510, after that perhaps a system with low compression pistons and rods to make around 580-630 hp. Problem with using forced induction in a high compression chamber is that you can't run much boost unless you change the internals.
In fact, G-Power offers 3 super-charged tuning stages. If you don't change your engine internals, they must run lower boost of around 0.35 BAR, install an air-to-air intercooler and piping, ECU and exhuast to get about 525bhp DIN and 368 lb-ft. This makes total sense to me and is probably more less the area where you could expect other FI kits to be in terms of performance.
