I was told they were 550cc High Impedance injectors. I did some research and found on precisionturbo.net, that the highest CC injectors they have in High Impedance are 525cc. Is there any way to tell what size injectors I have? Im going to tune my car and I dont want to put some small injectors in it.

get em tested, and find out what the actual flowrates are. u can even get em cleaned if they are the suck

Get me the #s that are stamped on the injectors, they make 525cc saturated and then 580cc which require are peak and hold.

 

Two of the injectors have this number stamped at the top of them, 3133 17113738. The other two have this number stamped on the top, 4232 17113738.

There are numbers that are also scribed on the side of the injectors. The guy told me they were tested by InlinePro and they wrote these numbers on the side.
I dont know what these numbers are, but it looks like the "45" numbers are the "Lb/Hr" rating, then these injectors are probably the 440cc injectors.

45.4
211
4.16.03

45.5
222
4.16.03

45.5
31
9.11.02

45.3
18
9.11.02

....I think I just got screwed.....hopefully im wrong about this...anyone else know what these numbers are? I plan on tuning my car to about 300whp, if these are 440cc injectors, will they be good enough??

ps. these are high impedance

Keep in mind the conversion for LBS/HR to CC/MIN is LBS/HR multiply by 10.5 so 45.5 lbs/hr x 10.5= 477.74cc strange since they don't make a 480cc

 

I just got off the phone with precision, gave them the numbers on the injectors, they are the 525cc

 

simple google search is your friend:

Part Number 17113738 (OE # 17104487)
Static Flow Rate: 50.0 lb/hr @ 43.5PSI (300kPa) 525cc/min or 6.4gm/sec
Static Flow Rate: 57.7 lb/hr @ 58.0PSI (400kPa) 606cc/min or 7.4gm/sec
Dynamic Flow Rate: 1.1 gm/pulse - 2.5ms pulse width and 10ms repetition rate @ 43.5PSI (300KPa)
Dynamic Flow Rate: 1.3 gm/pulse - 2.5ms pulse width and 10ms repetition rate @ 58.0PSI (400KPa)
Coil Resistance: 12 Ohms / High Impedance / High-Z (No ECM driver modifications required)
Cone Spray Angle - 22.4 degrees - single spray cone. Approximate cone angle for 90% of spray volume
