That is probably true, but also means they are just enlarging stock injectors to flow 1600cc which has been done before but they had problems with them.

I asked RC to do a set a couple of years ago and they wouldnt based on too many problems.

I would like to get a set and take a look at them and flow them on my flow bench to give them the test. If the guy selling them would like to send me a set to have a non biased opinion of them with a print out I would love to do it. If they are enlarged (my guess is yes) I would stay away.

I have a set of these injectors from Venom/python. They are top feed and for a different application (1800cc/min), however they use very slick looking (and functioning) much larger pintles. They do not simply bore them out and retain the stock pintle that was optimized for 850cc/min of flow.

I've also had them tested for flow, and for battery voltage offset / dead time. Both tests came out better than expected, and they actually slightly underrated the flow when viewed at the normal voltage for the voltage offset test. The atomization was "phenominal" in the report as well.

Now, all this means nothing if the side feed injectors are manufactured differently as compared to the injectors I have, for I do not have a set of the side feeds in my hands. Perhaps, someone can take a good, close up photo of the pintle area?

I was waiting for you to chime in. Rob told me you would give some opinion. However, these are not PYTHON, you are correct when you are saying python is boring the injectors out and remaning them.
These are MANUFACTURED injectors from VENOM. They are not taking old injectors and boring them out. These are MADE as 1600cc injectors.
Rob will be coming up there he said and you can see for yourself.
Maybe if you have a hookup, you can flow them before you install them on his car.
I had a supra owner buy a set of direct fit injectors, sent them to RC to get cleaned and balanced as he himself did not believe. The injectors turned out to flow more than they claimed and were 0.005% of eachother.

Newb question...the big advantage of these injectors is that they're side feed, so they're plug and play w/ the stock fuel rail, correct? Top feed injectors require new fuel rails, right? If I'm right about those 2 points, putting cost aside, is there any performance/functional difference between top feed and side feed injectors? Or does the position not really make a difference?

The only difference in performance is that side feed get better cooling inside the injector form the fuel. I dont see any other disavantages other then:

With top feed you would have to buy a rail, fuel pressure regulator, fittings, resisters, and fuel lines, to use and run properly.

Those injectors are very interesting, I would probably buy a set when it get's tested as far as durability...how long will they last...it may have good characteristics at first but who know's what will happen after a couple thousand miles of use...I would not want to be the test motor to find out that they will fail and blow my motor up...

I would rather spend the extra dollars and get top feeds with the rail which has been proven to work....

But then again if these injectors get good feedback after it has been used then I might opt to buy them too...

Did you ever question the top feed injectors when they came out??? No you took it for granted that they work. These are just the same. If someone grabs a set and gets them flowed that would definitely clear up a lot of things. As stated by one of the other members on here, his Venom top feeds turned out a lot better than he expected in all aspects.
I'd flow them myself, but im sure guys will still doubt me since I have them and im flowing them.

It's not that people don't trust u it's the injectors themselfs that make people a little worried because everyone knows that if they f**k up the engine is pretty much toast. As of now there hasn't been a side feed injector that big, so most people think that they are just enlarged stock ones (i know there not, just saying what people are thinking). But once a couple people have tried them out for a while, there will a lot of demand for them. That is if their engine still works. When people start knocking at your door for these, you can charge them as much as you want for all this trouble everyone put you through. hahaha give it some time it'll all work out

Spoolin Rotary

No I know its not me thats the prob, its the injectors and that people dont want to accept them for what they are and can do....lol.
Technology is getting better and better as we progress, so i dont understand how people can deny and say no way when something new has come out that is beneficial and cost effective.
But whats to say that you dont get a defective top feed and BOOM, or that a top feed messes up after a few thousand miles.???

The reason why is that there is no hard data on the injectors as far as what they are, now with that said if venom had those injectors on their website with all the info on them I doubt that people like me would be skeptical on those injectors.

Like I said once someone has tested them and gave good reports after long term use I will buy a set if it would still be available.

maybe paying more for something makes people feel safer.lol

Spoolin Rotary

The hard data you guys seek is b/c i'm an INDIVIDUAL with these+not well known on the forum even though been a member since 03. Here is what I think. If RX7 store had the link and was able to sell them im sure you would not question them once about anything related to the injectors, even if they had not been tested at all. You would have taken it for granted they were good.

no i don't think thats true. at least i wouldn't get them without knowing more about them. dont matter whos selling them. i would rather go with something that is tried and proven. ur inj. are new tech that no one has heard of. So until a few people run them for a while no one is going to trust these inj. dont take this personally its not u they're not trusting

Are you stupid?

Would I buy a Rolex from some dipsh*t on the corner or in Tiffany?

The RX7 Store has a reputation to protect. You don't have one to protect. Of couse the RX7 Store not going to stock some unknown injectors.

I agree w/ Bolo...it's matter of it being new, and not enough hard raw data (including long term feedback) for people to jump on 'em. As others have said, injectors aren't something minor that you can take a chance on. A prob w/ injectors can mean byebye engine.

Oh and regarding your example w/ RX7Store, Jason had gotten a pair of the Anti-det butt plugs not too long ago, and I don't believe anyone ran them. A 30+ page thread did come out of it, w/ everyone anxiously awaiting the results. I bet ya had the testing results come out positive, only THEN would have orders come in like crazy.

My simple suggesstion to boost your sales would be to supply someone (not me) w/ a set of these injectors free or at a discounted price to be a neutral 3rd party guinea pig...and trust me..if all goes well w/ his experience using the injectors, you'll prob be raking in sales faster than you can process the orders Just my $0.02

Even if the rx7store was selling them I still would not buy it unless it was tested and Jason had good results with long term use..

Perfect example is the AEM iginition amp, when it just came out and Jason was selling them I wanted to buy it but not many people had it yet, then people started buying them, worked good for a while so they were getting good feed back until it started shutting off due to heat in the engine bay...

I was glad that I held off buying it and not wasting money on them....That it why I would feel safer having other's test them first since with the injectors it would be the motor that will get hurt " very expensive " and if they get good long term results then I myself would purchase a set.

Spoolin Rotary

Well I guess you all are right in some sense, but some would like info from a verifed person. When Boosted! on here gets his set i'll try and find a local place to flow them, im not sure where I can get them done up here.

If someone on here is interested though, buy a set and I WILL REFUND your money if they do not flow 1600cc.
Just putting it out there if someone has the ability to get it done, and can put this thread to rest...lol
Im not out to screw peeps as im sure you all know by now, just trying to help.

Next topic, primary 1600cc injectors in the stock rail....lol

ha ha, good one, I hope that they get good results, I would love to buy a set if they work..

He didn't know he was just asking a question. If you are trying to sell something best to be nice.

Max13BREW

I cant seem to find the price for these anywhere. Can anyone tell me what they are worth? Might be interested in importing a pair to Australia...(Where I can get them flow tested easily..)

steve0178

so anyone tested these?
