however the real problem is that the injector duration is getting too long and I need to change the nozzels.
answered my next question.
having a shorter injection duration will lower the egrs? does this only apply to running larger amounts of boost and the fuel to match?
also are these a off the shelf nozzel by zexel or bosch or whoever?
what are your egrs and a/f ratio of your current set-up?
~20:1 AFR's and as for shorter duration; I should have said "I believe the problem now is injector opening is too long rather than it is... Im not sure 100%) I would expect it to lower the EGT's IF there is currently a problem. Otherwise... probably not. I am also worried that the combustion bowl is too small for the bigger injectors.
Regarding where the parts come from, it's not inexpensive R&D exercise, so I won't be spilling the beans on everything.
. I would really like to, but how else can i continue to try and improve products and the user experience if i im not funded to do so even if in a small way? I have an awesome set of products slated for the next 3 years that people will really benefit from. But, I can't do that without time (which means less paid work). If I left it soley as a hobby, not only would most vehicles be obsolete before I got the product out, the range would be limited and the really exciting (high r&d intensive) stuff wouldn't happen at all. The big guys are so top heavy that bringing out niche products won't happen - so if I dont do it, who will other than maybe the odd few enthusiasts? I'm a long way from giving up my day job.... but one day who knows?
While some companies offer gear that is dyno tested, not too many I know of test real world like I do. For example, I tuned my 1HD-FTE so that I was happy in particular with the auto shifts (the 5spd auto can wear clutches out easily if not done right) then towed a Huge load a long way tuning to ensure it could do the business (and not get hot or break and return great economy). I only dynoed for fun when I got back....., so the design brief was real world driving and checking what is required. What is required has a number.... But..... I made sure it did what I wanted first prior to testing on dyno. As you know, when you understand BSFC and drivetrain loss, the dyno figures are just proof to others.
