Injectors
In thinking about selling my 60 Lbs. injectors and go to 75 Lbs. Anyone knows who sells the 75 Lbs. with out having to pay Corvette Tax
I have someone else locally interested on the 60 Lbs. Injectors

My buddy with a Z06 just bought a new set of 75 low-imp he's not going to use, he'll sell them for $480 shipped.
I think RC Eng. (great injectors btw) has 750cc hi-imp for $98 each. They follow your goal for injector demand.

Not trying to steal thread
Funny, I was just about to post the same thing. Except I think I'm looking for 83 or 95# injectors (running out of fuel too quick).
Where do you get a controller?
I have roadrunner and don't want to give that up. I know I could go to the FAST system, but don't want to go through any headaches trying to get it to talk to the rest of the computers on board.
Are there any electrical engineers out there that can confirm to me that if I simply put a 8 ohm resistor in the common ground line for the injectors it should simulate the same impedance as a high imp. injector. And it wouldn't affect open/close times.
As I said, I'm not trying to hijack this thread, but hopefully any info will help Mike out as well as me.
Thanks,
Derrick

I know some people claim you can get away with current limiting resistors as a substitute for correct low impedance driver box. But I wouldn’t go there, because by design low impedance injectors open faster and allow less ON/Open time extending turndown. When you add resistor, time to open gets extended and voltage fluctuations make this even worse or can add unwanted variability.
A low impedance injector gets full power for x ms (milliseconds) then goes into a reduced power mode to keep coil from overheating or burning up. High opening power / current gets valve of seat quickly resulting in robust response. This high/low power mode is correct method to drive inject.
Tuning low impedance injectors with resistor will likely to be a nightmare.
