I dont get it, the car in the picture is hot lava and is different on your avatar. How is the kit?

These two don't go together. I don't buy it

Why not?

And you never made a thread for us?

Deets, man. Deets!

Wait, Marines? You learned how to write? That's awesome!

Full boost at low rpm to have more power will increase the gas consumption which means less efficiency. My JRSC has the same mpg with stock engine when driven normally. Power is there when I need, just a downshift away. I would prefer it stay that way.

Ah you're talking about "fuel efficiency". I was referring to compressor efficiency - i.e. centrifugal compressors produce less heat during compression compared to twin screw superchargers or roots. The benefits of the latter is lots of low end power, but with the downside of less top end power. A variable drive centrifugal compressor could provide the "heat efficiency" of a centrifugal compressor with the nice fat power curve of a positive displacement unit.

I wonder how much of that efficiency difference is consumed by the supercharger's transmission.

Not sure, would be interested to find out vs other setups like Rotrex planetary drives. Also wonder how reliable that drive is. Neat idea though.

How do you like it usmc fr-s? Any numbers on power? I like the concept considering kraftwerks eats belts.
