Can't tell from that pic and the link doesn't work to enlarge it.

I will bow down to the first person that can actually tell the difference from that picture.

Do you know who makes them or where they came from? It'd make it much easier to tell, some compains like go up 440, 550, 660 etc. Others all end in 50 (550, 650, 750 etc).

In all honesty, look up some injector flow tests, most injectors don't even flow within 10cc other their manufacturer rating. So unless you're trying to sell them, it doesn't really matter.

It's a Rochester injector the same kind sold by fuel injector clinic. But if it's not engraved on the side what it is flow tested for you are screwed unless you have it tested by someone.

 

[GSTdude06]

If yall had to guess what would yall say? Not 450cc or lower right?

:Edit: They came off of a modded GSX thats all I know :/

 

[Staytuned]

You can't tell from the outside .......550's look like 950's. You have to have them flow tested to find out for sure.

 

[GSTdude06]

ooooooooooooo but there not 450's correct? Or can you not tell those apart either?

 

[MyBeatGSX]

I have no idea if you can go by body size, but my 550's are physically smaller than that one. What does the spray hole pattern look like? Is it one hole or is it like a little circle of holes?

My bad I missed those last posts.

I'm guessing 450's would be the stock ones, those look nothing like the stock ones. But again, look at the nozzle pattern.

 

[GSTdude06]

Thats the only picture I have

 

[MyBeatGSX]

Are you buying these or do you already have them? I wouldn't buy random injectors from someone that doesn't even know the size.

 

[GSTdude06]

I was going to buy them. But if noone knows the size I wont.

Thanks for the fast responses!!

 

[Staytuned]

Well they are not stock 450's for sure. If I had to guess I would say 650's only because that is the most common size purchased for DSM'S. If I took a picture of my 850's they would look exactly like those. You cannot tell from the outside of the injector unless it is engraved with it's flow rate.

 

[GSTdude06]

Ooo ok well then these are better than what I have...stock 450's they are killing me here I have to upgrade and I believe 650 or 660s would be enough for me, I want around 300whp.

Here is a pic of the Forced Performance injectors that I have. See the markings on the side, that what your injectors should have.

 

[MyBeatGSX]

Just be aware you could be buying completely unusable 1000cc's or something far bigger than you can run. Not likely, but I'm just trying to save you some money.

 

[GSTdude06]

Do all big injectors have that lip on the bottom of them?

I cant make out the writing on the far left one. If that is writing.

that is engraved on all 4 of them is what the guy said.

 

[GSTdude06]

Flow Rate?

 

[a_scobel]

680 PTE injector...Just so you can compare. I don't believe you can tell just by looking at the outside, though.

 

[GSTdude06]

Do you not that what
25361/7 6144
20361/3 6144
18561/5 6144
16661/3 6144
that is? They said it was engraved on them. Flow Rate?

 

[GSTdude06]

Ok the guy jsut told me that they are Rochester injector's and they have 6 holes where they spray out from. Does Rochester make 650 or 660s? He said he is 100% positive that they are at least 650cc.

Thanks for yalls help
