Fuel injectors: the good, the bad, and the ugly.
Haltech e6k for engine management.
RB Rev II Exhaust, random cone intake, 255lph Fuel pump, BNR Stage 4 turbo, Stock Block, stock TMIC (yea I know...)
I was making 240hp @ 12psi (I think, it's been a while and that boost number might be wrong by a few psi) on the dyno before my engine took a ****. My tuner said I could have reached 300hp easily (around 20psi if I recall properly). I could probly make around 320-340 with a FMIC just because the intake temps were getting retarded with the TMIC. Just too much air for the thing to work properly even with ice and a fan on it.
The Injectors themselves should be good up to about 500hp before they run out of juice, so I have plenty of fuel, which is always good to know on a rotary

WTF is this 1:10 ratio you keep bringing up? I don't understand what that means... ID's are matched dynamically in batches of more than 200 injectors at a time. There is a standard and they do have waste from each and every batch that does not meet their standard. Not sure where you got that misinformation from...

I got it from this:
I wasnt aware of the modifications to the 1000s- can you go into more detail as to what exactly is done to them?
Do you provide the testing sheets with each pair or set of injectors? I had a pair but got them from another vendor and I didnt ask for one but it seems to be a big selling point of yours.
That chart shows how 10 randomly selected injectors match up out of a batch of 100 (unmatched and straight from Bosch). This is to show how much deviation can be present when you do a "grab bag" approach which is what that article is trying to address.

they are way more efficient at 15+psi. Though on the tmic, that is going to be pushing it. At 17psi a stage 4 will push around 350hp
what are the modifications done to the 750s and 1000s?
if you read what I wrote, you would notice that the reason I didn't run more boost was because my engine exploded during tuning... thus the guessing at numbers and lack of a dyno sheet.

dropped the injectors off to get flow tested, initial results are not too hot. only 5% variance 25%DC and the spray pattern of two of the injectors were garbage

so do the injector dynamics come peak and hold or all saturated
any idea on trickflow fuel injectors? I know trickflow is a big name with the mullet heads (mostly ford guys) and there products like aftermarket heads/intake quality enough to use on their race cars.

if you're poor, then get something else. But I went ahead and spent the extra ($460 for new 4x1000cc) and never looked back. They even have the added benefit of using different o-rings that are much thicker and stronger to reduce fuel leaks. I know I have had a lot of issues with tearing those damn injector o-rings and getting fuel leaks on my LIM. Maybe I'm the only one, but that was a big plus for me.
also, I know I sound like a spokesperson for ID or something. I'm not. I'm not affiliated with them in any way. I just like their product.
EDIT - you will be able to tune out the extra fuel from bigger injectors using your SAFC easily. I know because I've done it.

the drivers are not the same, especially if you examine the wave form on a scope.... removing the resistor pack would not solve this problem......
whats up with the "5" under my screen name lol?

.... knowing what i do about how injectors work and the differences in how the drivers wave forms are it seems like a poor idea. The accuracy of the injector timing and duty cycle would become compromised, IE run like garbage...
*shrug*
