I still don't understand how larger injectors are going to do anything on a NA vehicle...

 

NA, depends...With an accurate MAF reading, it could provide more fuel appropriately. But stock motor, without a tune or other factors, I dont know that they would do much. Increasing the spray pattern and level of atomization would possibly create a more efficient and effective burn, it may require hotter plugs or timing adjustments as well.

Not sure about fuel rails. They are just tubes. Billet looks cool, but unless they have a larger dia. for say, a SC'ed motor, or higher displacement etc...It will only look cool...

What it comes down to is all hearsay at this point. Now, If we take baselines of a stock motor, dyno, and emissions, then, change components, then re-test, we could make a finite and accurate asessment. So, who wants to fund my dyno time and parts??

 

alot of this is for replacment injectors if we find them for diffrent aplications that are cheaper such as the mustang 4.6l this is making part more affordible for people and im waiting to hear about the 12 hole disc that are for this style injector im gunna order some and see what they do on 24lb injectors whats the worse that happens its no improvment and i go back to stock but im willing to try it and im thinking of ordering the billet fuel rails if they fit great if not oh well

 

I have seen dyno after dyno on fuel injected Mustangs...

Modding the fuel system DOES NOTHING to increase horsepower...

Modding the fuel system is only necessary to achieve maximum horsepower based upon the air flow characteristics of the engine...whether it is NA or forced induction...if the engine has not been modified to suck more air, there is no need for bigger injectors. And, the only way to significantly increase the amount of air getting sucked in is serious top-end work (porting heads and port matching an intake, maybe, more likely new aluminum heads and intake) or bolting on an air pump (supercharger or turbo)...even then, at low boost, injectors are not even necessarily required...a Vortech s-trim running 6 psi will be adequately fed just with a larger fuel pump and a stand alone fuel management unit in most cases...

The difference between atomization patterns is not significant enough to justify the cost and potential hassle of swapping injectors. It is roughly tantamount to the stupid little tornado things that you can get on eBay that claim to optimize the pattern of air flow in the CAI...useless...

JMHO, of course...feel free to waste money on putting bigger injectors into a stock engine if you must...I would not recommend it...

 

Well said, that's exactly what I was thinking. Without more air, there is no reason to add more fuel.

 

a guy in the 3G section did it and had awesome gains. look at his videos. you can tell its faster.

He didn't post a before video so it's kinda impossible to know if it's any faster. I mean I'm not trying to say it can't happen but in theory it won't do anything. But I guess that is why it's a theory.

 

i dunno i asked in the other thread. i trust billys judgment when it comes to modding after spending hours talking to him. we will see what he says.

 

bigger injectors support bigger horsepower but usually don't make more power on their own. I went to 27psi injectors when I was running HO cams and the superchips because I was running lean at 6k WOT. I think Donkey was right when he said it has more to do with the type of spray vs being larger. -blown287
