Hey,
I've found this set for sale and I would like to know if they worth buying... I had 460cc RX7 injectors. Sold as new 750cc. |
Just get ev14's and be done with it.

No. Either get OEM ones from another car or Injector Dynamics.
|
garbage
|
Is the op still trying to build that high hp car or did they give up?

Why even bother making the thread if you were going to buy them anyway? My 460cc were from 1990... and they did a great job for 4 years upto 15psi (94%), I'll take the chance. |

My cats only show how much guys here do not like to hear anything different from what they say. I am no kid (40) and I tune cars and help the scene here in Israel (and remote tuning around the world). True, we do not have a race track so we are not at race level - but still. I will post my build progress so all the haters can hate. Engine will be ready in a week or two :) |

I so called "build ecus, tune cars, fi, itbs and others" I know the impotence of injectors but I also know that my old rx7 1990 460cc did a great job for 4 years and for others too, not using the absolute best and the newest parts is not always a mistake.
I don't give the slightest f*ck about haters, I keep asking my question all around - this is part of the learning process - no shame in no question. |
I started this thread with -146 cats now I'm at -154 - just for simply asking a question - some people here are just little babies and ugly haters -- that contribute nothing but hate.

You deserve every single one of the negcats you got in this thread. |
If I don't take your advice you punish me ? sounds almost like my dad - this is hard evidence for childish behavior.

I'm asking around and taking my own decision - like grownup not like a baby.

HAHAHA, You are a blatant moron.
And anyone stupid enough to waste their money on your "tuning services" clearly doesn't know any better. We don't dislike you for being different. We are appalled at you for being willfully ignorant and using garbage parts. Don't ever confuse those two. If you were smart, or doing something cool and impressive and innovative, we would all applaud you. Again, don't ever confuse these things. You can be stupid and very stubborn, and choose to do things terribly, but don't you dare accuse this forum of disliking you for your innovation. There is nothing innovative in what you're doing. There's tons of guys that we are skeptical of, and over the years they actually change our mind, and we start to support them. You are not one of those guys. Over the years, you've consistently proven yourself to make terrible, moronic decisions. You are exactly the opposite of what Savington is, and he's just a kid. If you are 40, then there is no hope for you. I thought you were just an ignorant young kid all these years. But I know you'll just ignore this honest opinion, call me a "hater" and move on with your ignorant life. So carry on :) |
You lost me at "HAHAHA"

Op wasn't born in the mid 90s?
Mind blown. |
I wanted to get some feedback about those injectors.

You wanted someone to validate the decision you had already made prior to making the thread. |
Not true.
|
So i am to believe that the input you asked for, that multiple people gave their time to supply, resulted in you buying these injectors?
|
The first one gave no input, second one said they flowed less then advertised, third and all the rest - no input.
My own experience was 4 years with 1990 rx7 460cc that did good. For less then a fifth of the ID price I was willing to get 850cc that will flow 750cc. |
I'm not sure how one can spend more than 30 minutes on this website and NOT gain an understanding that it's not about flow.
Like it or not, every post you're referencing was input. It's just not the input that you wanted when you created the thread. You asked, and i quote:

However go have shit idle, bad spray patterns, tuning issues and then future injector problems. Your time wasted is better than my time wasted. drop mic. |
I know about ev14 and I did my research, I had a simple question about getting the same kind of injectors that served me well for 4 years just with higher flow - that is all.
|
Yes, your sloppy dick Rx7 injectors served you well for 4 years. we get it.
here's a quick question: what PW do you idle at? |
About 1ms
|
that's the cycle time of 800cc injectors... without any fuel being injected.
|
ev14 start flowing at 0.85ms
1ms idle is totally normal. |

Some data from ID site.
|
you didn't buy ID injectors. From that same page:
Using just this sort of data, we have been able to determine the fuel usage of numerous engines at idle. How did we do that? Magic maybe? Nope…It’s as simple as recording the idle pulse width of a running vehicle, and then comparing that value to the curves above to determine idle fuel flow. Having this ability has allowed us to steer customers in the right direction knowing nothing more than engine displacement. It has also allowed us to sort the good from the bad insuring that everything we release is a quality piece. By examining the flow vs pulse width curves of any injector we can answer important questions such as “Will this injector provide a stiochiometric idle on a 1.8 liter Honda engine?” “Or a 1000cc 4 cylinder motorcycle engine?” We don’t need to wait for our pet tuner to try it out on his EVO, or his buddy’s WRX, we know before its ever installed in a running vehicle. So am I bragging? Not really. Just trying to make a point. If I had to hand this in for a grade, my point, or more accurately my conclusion would be that it is no longer 1985. For that matter, it is no longer 2008. This industry as a whole has moved forward at a rapid rate, and the ability to form logical conclusions from data, and to expect the availability of that data is commonplace. Gone are the days of tuning poorly-behaved injectors with little data, and even less understanding of what makes them perform so poorly. Gone are the days of asking your injector supplier for pertinent data and getting a response ranging from a condescending attitude, to a blank stare. So if you see an exception to this forward momentum, do the whole industry a favor and remind the offenders that its no longer 1985. If this article left you with an unanswered question, please let us know and we will be happy to clarify it for you. |
I understand your point, I canceled the old 850cc and got ev14 1000cc kit for the miata.

FWIW, I am using 540cc EV1 injectors and idle smoothly at 14.7, but I am only at 7psi for now.
My plan is to upgrade to EV14 before increasing boost, as well as install LS coils. Just wanted to throw that out there |
If you had enough brain cells you'd know that making power/boost doesn't require much injection technology, and idle/low loads is where this technology shines.
Also 540cc is a small injector, so that's not saying much. Also post a log showing this smooth idle you speak of, as well as some low load driving and throttle transitions, and we'll show you what a proper ev14 fueled log looks like. Just.......throwing that out there |
Well considering I just finished assembling my first turbo build and have a bit more tuning to do, I think I'll wait to post my logs before I embarrass myself. In short time I will post logs to my build thread and ask for community analysis and constructive feedback.
But for now, I am idling very smoothly at 14.7 I suppose that could be due to the smaller size, but I just wanted to state that it is attainable. Thanks for the offer though, I will definitely take you up on it! I will PM you once my logs are up to see what you think. And to OP, Real cats > Forum cats 2 > -23 |
I'll be genuinely impressed if OP actually did cancel his order and got ev14's. Doubt it though

I can vouch that he did :)
At least we got an informative article out of this thread. |
Yes my 94 came prewired for sequential injection, forgot to state that I am utilizing it.

all 94+are

now imagine if they flowed double the amount of fuel... you wont be at 15.0:1 anymore. |
I get what you are saying, but the ev14 lowest pw is about 1ms too... so we still 460cc 1ms pw vs 1000cc 1ms pw...
Please explain. |

Please explain. The opening time of the rx7 460cc injectors is closer to 1.2-1.4ms -- at least for anyone who's actually tried to measure them (some exercise we did back in 2010). On my own personal miata, with those same injectors, if I ever tried to inject less than 1.6ms of fuel in my miata it would instantly stall or oscillate wildly as it ran out of fuel. My normal idle PW to maintain 14.0:1 was ~1.7xxms. Here's what I know without getting technical: I've always had trouble getting rx7 550cc injectors to idle well on any miata. RC550s same thing -- very touchy to try to get a stoich idle. EV1 DW1000s couldn't idle leaner than 12.0:1. EV14 ID1000s can idle 15.0:1 smooth as silk. |
I checked some logs and at idle (900rpm) the pw is 2.0-2.1ms @ 14.7~, if I understand correctly, you say my old injectors were not big enough to show the problematic idle of old and big injectors.
|
correct. Once you move into >550cc you'll really see it.
