Hey, just got this off this month's "Banzai Magazine", hope this will be useful to those considering the Blitz Supercharger:

" The Blitz supercharger kit was unveiled at the 2004 Tokyo Auto Salon and marketed by the company soon after. Using this new package, the P-touring (RX-8) recorded 225hp at 8100 rpm. Admittedly, that doesn't sound like much of an increase, especially when Mazda rates the high power engine as producing 210-250 bhp. On a dyno, though, Blitz discovered "the high power" rotary gave a reading of only 180 bhp; less than that claimed for the low power engine. Torque also leapt from 163.5 lb ft at 5000 rpm to 183.1 lb ft at 4400 rpm, underlining the supercharger's low-end forced induction capabilities."

interesting how they got only 225 hp, but assuming the dynoed the stock using the same conditions and same dyno machine and got 180, we would assume that the supercharger gave a 45 hp gain?

Open for discussion
