Really?
I would never have thought that you'd reach the limit of air flow, the air filter inlet is what 5inches?? and the boost hose fitment to the metering head is 3inches? It's only really then what the turbo can suck in and what the head can flow isnt it?
I thought it was always the fuelling that toped out first, thats why people fit a 5th injector, to fuel for the extra air they are forcing in above what the metering head can fuel for!
