We picked up a set of 24lb/hr's and flow meter calibrated to them and 75mm housing yesterday. We're going to put 'em on hopefully this weekend.
I don't know much about fuel injection but I know when an engine is starving for fuel and when injector's are maxed out. Been threw it myself and had to learn the hardway.
With out putting a scanner on it and reading exactly what the injectors are doing, you cant say "It feels like" because no offense,.. but you dont know that for a fact. I made over 300 RWHP on a 4.6 with yellow top 19# injectors and they werent even at 85%.
He has a 240 - 250 rwhp combo. Thats it and 19# injectors are perfectly capable of handling that. His car with the combo he has should be running low 13's,. maybe some high 12's with a good tire and aggressive shifting.
Now thats not to say he doesnt have other issues causing him to run lean or out of fuel. C&L meters are notorious for giving erratic signals and just generally dont work right. I got rid of the 73mm one I had and went back to a stock housing and couldnt be happier. His pump might be faulty or the wiring to the pump could be faulty. Inline filters, clogged/dirty/defective injectors. There is a whole gambit of variables to trace down before saying the injectors are maxed out and causing the problem. I mean whats his fuel pressure reading? Is the TPS set correcly? Has the MAF been tested? How are the O2's? How is the general wiring condition and connections in the car? What condition are the vacuum lines in? So many things that NEED to be tested and checked first before you spend any money.
Do it smart. Dont guess.
