WI quantity calculations

[TAZ]

Hi,

Is there a guide or some calculations to do in order to size the nozzle capacity?
The engine is a 1.8T (VAG group) 4 cyl transversal with the std equipped K03sport turbo (KKK ...053).
The goal is to be able to advance the timing.

The WI system is a Shurflo pump (543226 P/N) factory set at 60PSI (internal switch??) , a shurflo accumulator, a std solenoid 12V 250PSI and i'm thinking a suitable nozzle system from spraying systems (probaply the small capacity LND type..).

As i checked the site i spotted some info from hotrod but now it's difficult to find it again... :? :cry:

Thank you in advance,
