To chage the cooler in my car is not realy practical would require alot of modification not something i wanted to do.
have you ever measured boost at the turbo end?
efficiency aside, if the cooler core is restrictive, you'd most likely find your turbo is actually pushing much more than 30psi and throwing hotter air into the cooler than it would if you had a less restrictive I/C.
a more efficient, less restrictive I/C will give you more power and allow you not to push the turbo harder than it needs to.
