This is pretty awesome! What made you chose the rotrex over a turbo setup?

Also, do you have any more pictures detailing the install? The ones you posted are from pretty far away and the image is squished a bit.

Same here, interested in dyno results, and pulley sizes (what's the Crank pulley?). Any idea what the intake air temps are at only 6PSI? Is it intercooled?
