I would like to thank Rick Cooper(Timebomb) for testing a few nozzles to find the following;
5x0.018" VCO nozzle
stock pintle - 3.0LPM
0.015" needle end - 3.3LPM
0.015" collar end - 3.5LPM
5x0.012" Micro-blind
stock pintle - 2.2LPM
0.015" needle end - 2.3LPM
These numbers show that all of those that have said in the past that pintle work is a waste of time, obviously make assumptions not backed by facts.
Something like this.
The next step is to test and see if any of this makes a difference. Hopefully it does.
These nozzles are defective. Someone forgot to disc grind the factory markings off.
Might as well go with the 148° Mack nozzle rather than the common 155°.
