So you haven't played with something in the order of 45cc out from injector to ECU scaling I'm guessing? Running 3.8 on 3.5l map is less than 10% increase, so I figure its easy for the trims to take care of that. Injector ~20% bigger would be outside what fuel trim can control I imagine, like you said.

It sounds like you just screwed around with the numbers there just to see if it would handle it-is that correct? That appeals to me, but trying to be pragmatic about things!

going from 227 to 240 pushed the trims from around -2ms or so to about + 6ms of squirt time with the trims maxing out at +/-16 ms I imagine that there is still headroom for another 20cc (around 260) in the ecu but without a wideband to confirm I would not risk it there is no need to do that normally. I was looking at upping the fuel pressure and increasing the injector size to compensate so I was not pushing duty cycles. However at stock scaling and 8psi I am not going over 65% according to the logging software

I decided to contact denso to try and find out the actual flow rate. The official position of denso is that they don't give it that any specs on their products. Seems a bit stupid to me, as it's easily figured out by the competition, but it is what it is. So, the figures stumagoo pulled out of the ecu for injector flow are as close as we can get to official

what the actual numbers are is almost irrelevant, the reality is the ecu rates one at a number of 227 and the other at 268 which is an increase of nearly 20% - so the magna ones are between 15 and 20% larger

Yeah, I just figured someone might want to know what they are capable of. I'm surprised they are that much smaller than magna

Me too. Actually quite keen to try either Magna or 380 ones myself but I am likely to do that when I do the 380 transplant

Being 12 hole I would think the 380 ones would be a lot better

I suspect so and as I am going to do the 380 swap and bolt the supercharger onto it I want the extra fueling if possible.
May have to use the 380 lower Plenum and get the Paj upper match ported or something else sorted
