Well i was reading a thread on skylineaustralia on shaved injectors. People claim that if you shave the four holes off the side feed injectors until you reach the single pintle valve that they’ll flow about 2.15 times more then standard injectors. Has anyone tried this? or heard of this? The only problem that people are having is matching all the injectors to flow the same.
heres the link to the thread

Wow, I wouldn’t suggest attempting that unless you’ve got a way to measure the final flow.
What a risk it would be to just do it and hope for the best…
that sounds like the stupidest thing you could possibly do
if one injector is even 5% off another one even with good afrs you could blow up
yeah that seems like an incredibly bad idea.
i bet they are talking about the same type of thing as the deatschwerks injectors where they are modifying them for higher flow… The Aussies are likely just calling them ‘shaved’ because ‘shaved’ is usually better than unshaved for stuff… you know
i highly doubt that they are actually just arbitrarily opening up the ends of the injectors… that doesnt really make sense for exactly the reasons sasha and max mentioned.
just like people break the pintle caps off, the injector tip then becomes a needle instead of mushroom … they will flow more, and if the pintle shaft isn’t bent in the process the injector variation will be very minimal… they seal on the inside so all you’re doing is removing obstruction and affecting spray pattern
but again this is equally delicate, best done by disassembling the injector and grinding the pintle down on a diamond disc… and who’s gonna do that?
Companies have been doing this with Subaru injectors with success, they go from the stock 450-ish cc’s to 816cc’s the problem is the spray pattern isnt as good and the tooling to do it must be exact.
Still, I would not do this to my engine. Is it really worth the risk?
If youve got the money to make your engine need more fuel than 450cc can give u have enough money to buy 800cc injectors.You dont need to risk all that money you put into it, + the effort and skills required to get it perfectly matched.
