[QUOTE="Hotrodtractor, post: 1314956, member: 25"] Go ahead and start a new thread with info. After it gets going a bit, I'll make it a sticky. Since you mentioned Dmax - and I tend to agree with Charles quite a bit on injection theory (shorter duration fuel injection at the right time is cleaner and more powerful) - my Dmax dynos about 640rwhp on 37x13.50s using a 60% over tip, a 10mm stroker CP3 pump, and 1.6ms of PW for fuel. Personally - when I pick injectors I try to pick injectors that can dump the fuel I want in the 1.5-2ms window. Its about getting a set of injectors that have fuel injection speed as well as control resolution to be able to utilize them appropriately. There are already posts on here and on PSN that discuss some of this. For this to work - you need injectors that you know what are and a tuner that knows how to use them correctly. Unfortunately in the 7.3 world things were so screwed up in the beginning that the sins of the past have never been truly washed away from the results of today. Anyone that is looking to put a 200% tip on an injector in a motor with a 38R is going to need to know exactly what is going on. While it is something I would do - it is not something that most tuners are comfortable with tuning for. Its not something that most of the guys looking to buy injectors should be looking at. Its just easier to make a long PW nozzle work for someone than it is to take the time and work to make a short PW nozzle work. [/QUOTE]
