anyone know what the box is to the right that has the Twin Speed sticker on it?

 

air to water intercooler

instead of the common air to air intercooler, this one uses water
the air from teh turbo goes through a small intercooler inside the box which has water circulating around it

water has a high latent heat meaning it requires lots of heat to raise the temperature by 1 degree
which means its an AWESOME heatsink material
