Not 100% the same flow rate, but close and lesser cost, for Lemmiwinks...
tuners that wouldn't be too big an issue. They flow a bit more than the RS2's do.
I got a set of 5 waiting to go in the 90q20v turbo for that 375bhp next step.
Cheers!

The delphi's were tested by nick and were a fire hose.
Checking to see if these are the same in question
but the racetronix are a delphi/lucas injector. from it's appearance, more to come

No these don't appear to be the ones Nick Tested..
Nick tested these

The racetronix, appear to be more of a lucas part then a delphi
<img src="http://www.racetronix.com/product/Injectors/Delphi_621037.jpg">
This is what is said regarding the lucas (still not clear where the delphi part comes in)
Delphi / Lucas
37 lb / hr. Disc Injectors
Part Number Delphi D3165BA (Lucas old 5203002, Lucas New 621037)
Static Flow Rate: 37.27 lb/hr @ 43.5PSI (300kPa) or 282gm/min
Dynamic Flow Rate: 8.42 gm/pulse - 2.5ms pulse width and 10ms repetition rate
Coil Resistance: 15.9 Ohms / High Impedance / High-Z (No ECM driver modifications required)
Additional Information:
Top feed disc injectors use a small disc with six holes around its circumference. The disc rests on a short chimney that surrounds a metering hole. As the disc is raised off the chimney by magnetic force, fuel flows through the holes in the disc, over the walls of the chimney, and out the metering hole to form a full, finely atomized cone.
Performance advantages over pintle injectors (i.e. Ford / Bosch & Accel types) as listed by Delphi:
* The flat mating surface ensures that no excess fuel is present to evaporate and therefore, no deposits or clogging can occur.
* Compatible with alternative fuels (i.e. Methanol)
* Longer service life
* High-speed disc action allows wider dynamic flow range for improved idling
* Quieter operation
* Revolutionary disc design resists build up deposits which can affect fuel flow.
* No Fuel leakage for quicker starts
Delphi / Lucas
42 lb / hr. '009' Disc Injectors
Part Number Delphi 01D030B (Lucas old 5208009, Lucas New 621031)
Static Flow Rate: 42.29 lb/hr @ 43.5PSI (300kPa) or 320gm/min
Dynamic Flow Rate: 9.96 gm/pulse - 2.5ms pulse width and 10ms repetition rate
Coil Resistance: 15.9 Ohms / High Impedance / High-Z (No ECM driver modifications required)

could be a 2v vs 3v intake layout, 2v will probably flow in pretty even with the pattern I tested
3v is going to be rich in the middle and lean on the sides and hope it all mixes in the chamber.
dunno, I'd like someone else to try them too
