In the search for the "safest and most reliable" power upgrades for my 9000 I've got all the airflow sorted now (with the exception of possibly adding a flowed & ported head) and am now turning to the fuelling and, more specifically, the injectors.
A brief period surfing has unearthed some useful info- like for example around 300hp is right on the limit for the present injectors because it requires a very high duty cycle (somewhere towards 90%- best practice says no more than 80%, ideally below 70%). The problem with high duty cycles is that you start getting unpredictable performance.
So, I'm on the hunt for uprated injectors to make sure things are running happily. AS a starting point, I'd like to confirm the Bosch OE part number, which I believe to be 0 280 155 009. Can anyone confirm this?
Secondly, it would appear that one of the Bosch 400 series, particularly the 0 280 150 403 may be suitable. Can anyone confirm or deny this?
Lastly, does anyone have figures for the fuel pump flow capacity?
Sorry for all the q's but I promise to post back the results for general consumption!!
