12PSI 2H - How much air is needed? (1 Viewer)

Apr 11, 2014
Hi guys.

I have my 2H running at 12psi, and I have the standard 'Landcruiser' snorkel
I took this apart the other day and noticed the plastic had 'shrunk' at the join a little making the internal diameter rather small.
Im wondering if this might be choking the system? How much air do I really need? I would have thought that 12 psi would want a fair amount of air coming through?
Fuel economy about 450 k's to 75 litres..... is this normal? or would more air increase this??

Thanks in advance.
