Okay, I know it's kind of overkill, and it's just and idea at this point(one that's been running through my head and won't leave). But Has anyone thought of doing twin turbo gt15's? Or one gt15 and one gt17 for different characteristics and less lag? Any pro's? What would be the con's? Aside from custom built stuff?

I think it's much more interesting to use a small turbine with big compressor and external wastegate. std 998 A+, g295, MD266, RHF4, 109hp @0.8bar/5400rpm |

The rotrex thing interests me, but I'd need at least 7 ports to go with it On 11th Feb, 2015 robert said:

It's actually a very basic technology, except the very high-end material used for the rotor. WRC rev limiter is at 7500 rpm. std 998 A+, g295, MD266, RHF4, 109hp @0.8bar/5400rpm |

was going to say exactly the same, ish, least torqu-ey of any supercharger if you want a supercharger you want something like an eaton/rootes, if you want a centrefugal compressor you want a turbo :)
turbo 16v k-series 11.9@118.9 :)

: how about turbo *and* supercharging? Mr Gale Banks is doing this with the GM 6.5 TD engine with impressive results, not so much in hp (about 550), but torque
