Default Re: Questions on my direct port meth setup

A 4mm line with a 2mm ID with a 2mm ID has a volume of about 3ml per meter.
That dribble from 4 nozzles spilling over the course of few seconds won't blow up anything.
With aggressive cams you blow way more fuel from the cylinder into the manifold under those conditions.
Even fuel cut on overrun will continue to inject fuel for a few hundred milliseconds tapering down to prevent catalytic converter overheat from sudden inrush of excess oxygen.
