[QUOTE="Demonic Diesel Performanc, post: 813713, member: 12757"] Pre injection is a plus in a common rail system at low rpms, it can be turned off with great success after about 2000 rpms...post can be eliminated all together with out adverse effects "minus emission out put" The presssure spike can be roughly formulated with timing, fuel quantity, cylinder temps, ect... The pressure really dosent mean much after 2000 rpms... once you get the rotating assembly moving at those speeds it can handle a lot! Now big pressure spikes in the 1500 rpm range can easily bend or break a rod... [/QUOTE]
