Title: PP764's - what's the best pop 1st/2nd stage pressures?
Post by: greg123 on December 22, 2008, 08:32:23 am
Seasons greetings.

After run-in I’m going to have these new PP764's from Kerma tested/set up. They are going in a UK model 110tdi of 2002 vintage, which is otherwise pretty stock (EGR delete, dual fuel vegoil - it has the VNT15 from stock as it's a 110hp).

What are recommendations for 1st/2nd stage pop pressures? I hear better results with higher pressures than the 220/300 bar stock due to the larger nozzles messing up timing with stock pressure. Found a few threads but nothing definitive.

Anyone has any advice?
Greg.
