We used a "roots type" supercharger called VOLUMEX. It has been created for the old grp.B FIA rally cars but modified by us. We fitted also an air/air intercooler, remapped the Ecu and changed the exhaust system. The engine is strictly derived from that used in the "RX8 Sport Cup".
It sounds like an UFO and flames from the rear exhaust even with usual european 98Ron fuel.
About a street application....who knows?

Can you go into more detail on how you did that?

Yes.
First we have to disconnect the main chip (CPU) from the board, closa e "jumper", then we have to reprogram it. We modify the mapping LUT with a freeware sw that can be also downloaded from my website. The only problem has been the checksums, but a Milan based company fixed thi problem. Thats it.
About tha MAF sensor, i read a lot of people think it is the mai problem, but i don't understand why since we had no problem to manage absolute pressures up to 2 bar just only with a few little changes.

Hmm. I wonder if this is the "technique" that JDM tuners are using to do their re-mapping? The same goes for Racing Beat, or did they get something from Mazda for their effort?
