injectors

[Kevin O'Connell]

Are our injectors 24lb/hr? Saw an ad that offered 30lb/hr on up- other than reprogramming ECU to take advantage of extra fuel and control A/F ration and timing, are there extra HP gains out there once the air intake and exhaust have been opened up(open air box vented to fender well, no snorkel, K&N panel, smoothed air tube and complete Geno's exhaust)?
ECU changes to IMRC opening rate and duration?

Yes, our injectors are 24# stock. Unless you are running an aggressive NA application with cams/headwork and/or power adder, I see no need for bigger injectors. The stock ones will do you just fine.

OK, how do you know if we're getting full output from the stock ones?

If you're not having lean condition problems, you don't need to mess with injectors. Our 24lb injectors are fine until you look at forced induction/huge dry shot of nitrous/maybe an all out NA build. An all out build does not equal intake/exhaust, think 8500rpm, .500 lift cams, ported heads, high compression, etc.

If you are looking for the exact measure then you need to data log the car and tweak with the fuel tables, which requires a program from SCT and the gear to go with it, or take the car to a tuner and experiment with different settings. All of these cost something, but in general you won't find much to worry about with the mods listed. You'd get more out of a chip from some of the vendors who have developed chips for the Mark Vlll.
