why large bore intakes such as B5 one work... on IHI's also 55g/s gains

Car in question came in with an ihi vf34 turbo kit on it, done by a.n.other company.

.. started addressing the TIP..

As it arrived, remembering it was previously a k03 tip with glued on silicon to upsize it to the vf34's much larger intake..

Mock up... ready to machine to VF34 dims

remember this vf34 was having to breath thru a small inlet... for k03!!

Peak figure gains: previous highest airflow 219g/s @ 5000rpm @>1.5bar boost
Current airflows with badger 5 made 3" intake is 274g/s @ 7000rpm @1.4bar boost

55g/s gains!!

Wow that's impressive £ per bhp that has to be one of the best mods available. Just goes to show what having the right additions to a BT makes!
