From what I can glean from trolling the net, the big difference between the 2 types of the 764 nozzles is that the PP has 7 holes while the "new and improved" DLC764 has 5 openings. Slightly increased overall flow (87%>103%) on the PP's, but to my surprise I find that DBW lists both as being DLC coated. The PP's are ~ $50 cheaper.
Is there a consensus as to whether there is any significant advantage
to a 7vs5 hole orifice?
With DBW's option of increased flow rates with spring setup, ie. a DLC764 could be bumped up to the same rate as the PP(DLC)764.
I'm also considering the 10% plus stage 1 injection mod as well,
according to Pete it would improve lower down spooling & torque.
I'm not looking for the ultimate high rpm horsepower, more low down grunt for towing a small tear drop camper (~1200#) around the country next year. With an 11mm pump my goal is on the order of 160-170bhp/300'#s.
I'll be picking up a 17/22 turbo this weekend, and an SBC2 End clutch. The combo should be more than capable of dealing with the bigger nozzles.
Thoughts, input, and experience on the 2 types greatly appreciated.
