Right I went ahead and fitted the nozzles. The fork holds the injectors on the right side on the alfa head, and on the left side of the injector on the HDi head, meaning angle must be slightly off. But I'm quite impressed by these nozzles. AFR is lower now with same amount of fuel and bost (~17:1 at full throttle, 4.000 rpm, before ~15.5:1), meaning better combustion than before. (compared to the original nozzles). I can utillize higher revs now due to the much shorter durations, it can pull hard to nearly 5.000 without problems. Before it would start smoking at ~4.100 due to EOI being to late.
Only "problem" is that the turbo build boost slightly later due to the far better EOI, but that is only a matter of mapping. Turbo control in closed loop is better now, again due to better EOI.
Now let's see if I can reach 220BHp with these nozzles, I was at 206BHp before with ori nozzles.
