psi per say is not the be all and end all. for example a small turbo, running 7 psi will heat the air up more than a large one running mabe 12 to 15 psi.

is the turbo on the 220 cab a hybrid of some sort?

also the turbo technics intercooler on the twin turbo 103's is a neat piece of engineering, fitting well in the space and looks fantasitc, but it willl not flow more air than that required for around 400 bhp

so if this 220 4 pot has a hybrid turbo and a very good intercooler, the power may be high up there.

the higher power per psi due to lower charge temps is where im going next with my air to water setup... coming soon.

"some mods improve your car and make it into something it never was, other mods, however, although essentially the same, are not, and make that car a ricer"

if your car isnt shiny, you dont know what you are talking about, remember; paint shine = knowledge. In order to be taken seriously, you should spend all your money on paint, (and get a dyno reading).
Dont forget to polish it often
