Title: 24# INJECTORS
Post by: SKI BOY on October 12, 2008, 08:09:04 AM
Anyone know the difference between the Ford 24# injectors from street Mustang & 24# Ford Racing injectors from the Cobra? Would the Ford Racing be suitable for the 2.5L? Thanks for any help!

Don't know if their would be much difference between those injectors, but your stock injectors should be 23.2#.

If I had to guess I'd say they're matched.  Although that may not be the case.

the best way to see if your engine needs bigger injectors is with a scanner. under full throttle at 4500 rpm, look at the injector pulse or "on-time". if it is anything close to 13 milliseconds. you need bigger injectors. If you do the math at 4500 rpms, the engine is turning 75 times a second. convert that to milliseconds and its 13.3ms. which means if the injector is on for 13ms, it is only off for 0.3ms. which is close to being open all the time. time for bigger injectors. the pcm will compensate for slightly bigger injectors
