new from racetronix, 79# HIGH IMPEDENCE injectors.
has anybody tried these? new era boys? do they tune nice? i think i just creamed my pants because i did NOT want to buy a driver box. i was just going to see how far my 60# injectors would take me boost referenced…
we took 75rc’s for a spin and they didn’t seem to want to play nice
Hmmm looks pretty interesting:
Specfications:
Static Flow Rate: 76.65 lb/hr = 9.67 g/s = 846 cc/min (+/-4%)
Dynamic Flow @ 2.5ms PW @ 100Hz: 16.88 mg/pulse +/-10% @ 2.5ms PW @ 100Hz
Coil Resistance: 12.2 Ohms (+/-0.35 Ohms) (This high-impedance injector will work with all factory ECM/PCM injector drivers)
Spray pattern: 3-Prong Cone
Body: Top-Feed EV1 Style Body
Factory fitted with Viton upper and lower o-rings
Grease supplied to lubricate o-rings prior to installation.
Dynamically flowed and grouped within 1% with Racetronix injector flow bench
Racetronix Part # L107 (Siemens FI114961 - Mototron INJ-GAS-006 - Accel 74620L - MSD/Edge 2030)
Static Flow Rate @ 43.5PSI (300kPa) w/Gas: 63.20 lb/hr = 668 cc/min = 475 g/min *
Coil Resistance: 12 Ohms / High Impedance / High-Z(No ECM driver modifications required)
Gain: 0.11ms/mg
Offset: 0.055ms
Turn on time @ 14VDC: 1.14ms
Turn off time: 0.85ms @ 600KPa
Factory Tollerance: +/-6 %
Spray Pattern: Cone
Connector: Minitimer (Bosch EV1)
Delphi Part Number 17113742 (OE # 17104988)
Static Flow Rate @ 43.5 PSI (300KPa) = 75.0 lb/hr / 9.5 gm/sec / 788 cc/min
Static Flow Rate @ 58.0 PSI (400KPa) = 86.6 lb/hr / 11.0 gm/sec / 909 cc/min
Dynamic Flow Rate @ 43.5 PSI = 1.75 gm/pulse - 2.5ms pulse width and 10ms repetition rate
Coil Resistance: 2 Ohms / Low Impedance / Low-Z (Peak-hold ECM drivers or impedance converter required)
Cone Spray Angle - 22.5 degrees - single spray cone. Approximate cone angle for 90% of spray volume
I think you would be better off with an impedance converter and low-z injectors (more current to move a heavy pintle/disc) which leads itself to faster opening and repition rates.
I would think it would matter more if he rev’d it into the high end of the 6500rpm range …plus.
