Proof to back what up? I didn't state an opinion, just a description of how the fuel injection system works.
So based on all the info you've stated are you saying these injectors are better than the ones toyota and denso developed? There's a reason the factory ones are around 100 bucks a piece. You get what you pay for.
What exactly is a "aftermarket air-fuel wide band controller" that you installed? Did you install a wide band air fuel ratio sensor? The "controller" is the ecu so that doesn't even make any sense.
I'm with you.
I just want some numbers, lol. That's all. I don't mean to incite riots or anything. Not looking to offend anyone or say anyone's wrong. I just want some objective evidence for the sake of learning.
Maybe it's me, but I feel like this is the conversation I'm having with folks on this topic:
Me: "Interesting idea. Any data showing the improvement?"
Others: "No. It won't show up on a dyno at WOT and it's too hard to show it in any other test. Just try it out for yourself. You'll feel the difference."
Me: "Hmmm... that's what I hear about intake tornados, Electrical filters, Oil additives, gas additives, etc... I think there's gotta be a way to show the data for this improvement."
Others: "No, it's just facts. Better atomization = better performance. It's science. Buy it and see for yourself."
Me: "Uh...."
Yes, the 12-hole injectors are seen on newer models/engines. Yes, it makes sense that they'd atomize slightly better in the intake manifold than the 4. Does that result in better performance? I don't know, but I need more than some butt-dyno commentary to be convinced. How do we know the difference felt isn't the difference between partially clogged, unclean 10-20 year old injectors vs brand new, clean ones? Maybe the injector holes makes a 0.5% difference and the cleanliness makes a 6% difference. If that's true then the recommendation shouldn't be to spend $300-800 on new injectors, but rather a cleaning service for $100.
RC Engineering or Injector Dynamics never seem to mention # of holes in their product listing of high end injectors. Are they missing this secret ingredient? Have I missed people building performance engines bragging about the number of holes in their injectors all these years? Maybe, I suppose.
Atomization also changes throughout the intake path. Atomization may improve or degrade as you flow from the injector site to the combustion chamber. This could change any upgrades made at the injector itself.
There are a ton of variables here and nobody seems to have the desire to build a data set on this. Therefore, my skepticism only grows...
Raw data from a half day on a dyno with a fresh set of 4 hole and a fresh set of 12 hole injectors would prove this all out. Just get on the dyno and run many runs at varying throttle input. You could plot the throttle input or load against the output power and account for minor variances (it'll be hard to hold exactly 25% throttle). With a wideband you could also plot the AFR differences (if any) in closed loop. You could monitor injector duty cycle, fuel trims, etc... the list goes on and on. Instead we have nothing. No data from anybody aside from a few MPG posts from a couple tanks of gas and a video of an AFR gauge with undersized injectors.
I just want data!
