Since my name was brought up a couple of times in this thread - I'm going to make some comments that may not really answer the OP's questions - but its some info that I think people need to see and know about. Many people have asked me about the injectors that I have spent time and money on creating - I have no real desire to speak about them directly or specifically -but want to show some things about injection speed and control.
Here is the graphical representation of a standard set of 238cc hybrid injectors with an "80%" tip:
Now certain things can be done to those injectors to improve the injection speed - things like a larger tip, fuel side injector modifications, etc.... that is easy to do and the initial results show pretty substantial gains in flow rate across the board:
Now that's all well and good - we've got more fueling capabilities - but at the same time we have lost a bit of control resolution making them harder to tune for - you just can't dial down the tuning as quickly and easily in certain areas and the transition periods going from different ICP settings or PW times can be a little finicky - this is shown mostly by the sloping of the injection graph - its nice and steep from all angles and ramps up to some pretty significant fueling capabilities. The real trick is to continue with the modifications to the injector to improve upon that control resolution to make it better to drive, easier to tune, and overall more of a pleasure to own and enjoy on a daily basis with more power and RPM capability than what are current standard issue injectors:
Now before I get criticized - the first two graphs are actual data - I used actual data that I have to mimic the third graph for this example to make it a better visualization for everyone. This is the same volume and the same injector tip, and even the same "fast fuel" mods - but it has other things that have been tweaked to further improve the control. This is what makes a high flow rate injector more controllable and driver friendly - take note at how it has a much less steep fueling curve.
Now I brought up this information because myself and the vendors that I deal with for injection have been slowly working on improving the control-ability of the high flow rate injectors on our own time and our own dime. The injection rate that we have is well over 400cc of fuel in a very usable time window - the trick is controlling it effectively - I have no desire to give the OK to the vendors to begin shipping these injectors that are finicky to tune and control.
So if money was no object - well over 400ccs of fuel in a usable time window in a controllable package could be finalized and sold. We all recognize that its a short and dying list of people that even care any more about this - there is really no way that we can recoup the costs even at this point - that is why we are not rushing anything - its a losing battle on the money front and we are doing it for us - when things are ready - they would be available through the vendors that I work with.
