Hello Gord. You have misquoted, but I assume you are digging at me again. This subject has been done to death already, but I'll explain again:
Using a fuel return line and elevated fuel pressures are aged methodologies which have the unfortunate side effects of maxed out injectors and fuel pump. This method is normally a last resort in the absence of a better solution. It is indisputable that larger injectors and a calibratable ecu is a better solution than a fuel return line and fuel pressure regulator etc, because the injector duty cycle and fuel pump are working within their design specifications and parameters.
This is off topic (sorry Nico ), so it is best to leave this issue to Engineers and customers to decide on their preference.
Mark - Not sure if it makes any difference but Nico also has a uprated fuel pump as well as the other bits & bobs you mention. On the early power runs the injectors maxed out (as expected at 250 + bhp) but the techy did something with fuel pressure & lowered boost a tad so now not at full load (close though)
Nico may want to upgrade his injectors later.
He called me en route saying how much he is enjoying the car in its new guise. I'll let him report in detail on that tho
No, it doesn't really matter Dave - the principle is the same.
What dyno was used? We couldn't get anwhere near a genuine 250hp using these methodologies and standard injectors.
Glad to hear that Nico is pleased - he seems like a lovely guy and worthy of the very best service.
Hi Mark, that very intresting statment you make about, not getting anwhere near a geniune 250hp using these methodologies and standard injectors :o
When you did the turbo for Mr skippy (the blue one, dazza w now has) did it or did it not, have 260hp when it came out of TDI (im sure someone has the printout that came with the car) and Mr skippy has printouts of 250hp, 284hp and 292hp using standard injectors.
now in sure that Nico's car will have 250hp as the principle is the same :D YES
he has printouts does he ??????
print facts not fiction
just for moderating sake has gord put anything to this thread to
help nico or dave (prolex) if not lets wipe the rubbish and get back on topic
so nico can get is car sorted
nico have you actually seen a dyno sheet ??
