Default What is the biggest high imped Injector?

Just wondering what the biggest stock pcm compatible injector is now? I thought I heard someone had some 96's working? Or is 79's still it?

I have seen think 83s..on racetronix site..or 79s..something like that but think they are like 80 somethings at ls1 pressure and you can of course push them even farther with higher base pressure boost referenced.

I used to see Venom advertise an 83, but I never heard good things about them. The biggest I've seen actually in use are the ones I have: 750cc/min or ~72 lb/hr from RC Engineering. Working great, no problem with idle tuning at all.

Oh and the 72lb/hr is at a rated 43.5 psi, so at 56psi they would be more like 75 or 76lb/hr, maybe a tad more.

So how do they idle? Any advantage to still go low impedence when these exist? maybe only if you still need a lot bigger. I have also heared the mototrons can be run past 80% with no problems. Is this true and if so what duty cycle would be max on them?

they are at 4 bar and will work with your stock pcm
or you can use the lucas disc 75 that some guys sell as 79's these are rated at 3 bar. At 4 bar they flow about 83 also. These are unmodified
