ok so all the info is here on our site just click on the injector you need data for and you will see the data table

how about 4x2000 on a bridgeport??????? sound better and easier to tune than 8x1600...

that way, i would be able to keep my stock manifold setup!

2a+RoN

Yeah you could do 4x2000's. Guessing E85 or Meth? We have run an N/A 13b on gasoline with 2x2000's in primary position and worked flawlessly. Also have a customer who ran a suby on 4x2000's on both gas and E85 and maintained a perfect stock idle.

i am looking to possiblly make the switch to ID. the primary reason is i plan to run 100% methanol when i do the Texas Mile in October.

so i am looking for lots of delivery. 10,500 CC/Min.

i run a GZ LIM so i have 6 ports and am thinking 6 ID2000s.

my question is:

ID flow rates, as i understand from reading the site, are given for gasoline.

most other injectors are flowed w higher viscosity test fluids. this higher viscosity (V gas) would understate delivery V ID.

so are we talking apples and oranges or apples and apples?

perhaps Bosch, for example, does a conversion to gas based on test fluids?

perhaps a simple question to ask of ID is do your 1000 CC injectors flow the same max as non ID 1000 injectors?

BTW, i don't pose this in a negative manner. i understand the rational for using gas, i just want to understand what i am being offered.

Howard, I've tried the ID1000 and 2000's. I used to run RC Injectors, 750 primary, 1600 secondary. I swapped in the ID's thinking I wanted to try E85 and that the increase in size would closely match the added fuel needed. However, in my experience it didn't work out quite as well as planned.

When I first put in the ID's, I just tried changing the base pulse width on my map about the same amount as the % difference between a 1000 and a 750. Car wouldn't start at all. After much playing around and getting it to start, I'd arrived almost back where my normal map was. So I popped my normal map back in (for the RC injectors) and the car fired right up. Huh. Granted this was at startup and idle, which are not the most efficient spots on the map.

So, my guess was that between the ID's being flow rated with gas (instead of some other fluid) they aren't quite apples/apples, and that they are saturated vs. peak and hold I wasn't getting the injector size increase I thought.

I've since retuned the car on gas with a base pressure of 63psi and the ID1000's and 2000's. Car does run great, throttle response is excellent, and tunability at low pulsewidths seems noticeably better than the RC's. However, seeing how much fuel I'm running now, I'm not sure if 2 ID1000's and 2ID2000's will be enough to make 400+whp on E85 without pushing the injector pretty hard. YMMV.

If anyone wants the Orings for the injectors to seat into Orielly's has them, but you have to ask for an injector kit for a FC. If you just ask them for the Oring they will have no idea what you are talking about and point you in the wrong direction. It will come w/ all the O-rings for the FC injector. Runs $8 per injector.

Hmm, not sure what happened then, and unfortunately I already deleted it from my sent mail.. I went into a lot of detail answering all of your questions too..

Comparing our flow numbers with any other aftermarket injector company's is like apples and oranges. If you want to compare apples to apples, you could compare our data to say an OEM's injector data as we are both geared towards real world results and not comparing injectors to each other. I realize that you are trying to most accurately calculate your fueling needs, but it is difficult to accurately compare the two. If you send me your injectors, I will gladly test them and get you accurate data on your current fueling so that you can compare apples to apples.

I can tell you that 6x ID2000's is ~13,200cc/min of fuel which will definitely provide enough flow for 100% methanol (they actually flow 2200cc/min at 43.5psi on gasoline), and the 2000's on primaries have low enough pulsewidth extension to idle like stock on gasoline..

What's your email again so I can resend our horsepower calculator?

Also, I remember you asked for a suggestion on fuel pump. I think a weldon would be your best bet for that much fuel.


AMRX7, did you input all of the provided injector data when you installed our injectors? And did you have the correct data in for your RC's? 2xID1000's and 2xID2000's should provide enough fuel for ~500whp on e85 at 60psi. What duty cycle are you running now and are you logging fuel pressure??

AMRX7

I run a Tec3 which only allow ones correction number for voltage, and it is the same number for both primary and secondary. I don't recally exactly what I put in, but I had to take a best guess average from the supplied data sheets. I don't think it differed greatly from the number I had in before for the RC injectors. So, until I upgrade the ECU, I'm missing out on alot of precision the ID's offer.

I should have added that I run the motor to 9000rpm, so the injection window is getting fairly small and makes the duty cycles go up. I just dyno'd the car again this week, so I can go back and see how much pulsewidth I am running with the ID setup vs. the RC. I will have to correct for fuel pressure though, as I was running a lower base pressure before.

I do not log fuel pressure. I have a gauge running off a transducer, but haven't hooked into the ECU for datalogging. Fuel pump is a SX Performance 18203.

Don't get me wrong, I think the ID injectors are great and make perfect sense which is why I bought them. I am very curious how the flow rates with my ID setup vs. the old RC setup compare so will see what I can tell from my maps.

The ID injectors have a very short recovery time and are capable of running higher duty cycles than most older style injectors like the RC's, so even at 9000rpm, they should still easily flow enough e85 for close to 500whp. If you would like the calculator as well, PM me your email address.

Got a question, what setup would be better?

id720 primary
4 id1000 secondary

or

id 720 primary
2 id2000 secondary

lets say HP goal is 500HP with gas not E85

Based on porting size I would say 4 injectors @ 1 per port, and 725cc or 1000cc primary are fine hence why i have like 4 x 1000cc ID's for sale...lol

2a+RoN

If you're planning on using Q16 ever, go with the 4x1000's on secondaries. However, if you plan on going E85, the 2000's will give you a little more room to grow.

haydenw

I have heard that Injector dynamics injectors are not compatible with q16 due to the oxygenate used ( MTBE) but is ok with E85, have you had any experience with this?

2a+RoN

It is ONLY the ID2000's that are not compatible with MTBE, and that is the only compatibility issue... E85, meth, etc. are all fine. The 1000's and 725's are compatible with all known fuels.

Sarusanj

So, 2 ID1000 primaries, 4 ID1000 secondaries= just enough for 500 whp on E85? Or plenty enough?

Slammedblk7

iTrader: (7)

Running (4) ID2000. Hoping to push around 600whp+. Enough fuel on E85?

haydenw

Whats the reason for this compatibility issue?

2a+RoN

Sarusanj, 6x ID1000's is probably just enough fuel for ~500whp, and will require higher fuel pressure, so therefore some decent pumps..

Slammedblk7, yeah 4x ID2000's is plenty for 600whp. They are very capable at running elevated pressures as well in case you want to make even more power..

haydenw, there is a valve seat in the ID2000's that does not like MTBE.. It does not destroy the injector, but limits the flow significantly. On the q16 pales, they note to not leave in fuel systems, so I'm sure they are aware of some compatibility issues with the fuel.

Does it matter how you wire the injectors? (power and ground) ?

Hi Im Simon

iTrader: (6)

i'm kinda new to this so you guys have to humor me. I'm throwing on a GT35R using the Xcessive LIM. can i get away by running 4 ID1000's using their fuel rail and would that be enough fuel? i'm reading that idle might not be that great? i wanted to keep the fuel system simple. kinda confused.

thanks for the help

iTrader: (13)

What primary injectors are you running?

Hi Im Simon

iTrader: (6)

none. i was only planning to running 1 fuel rail.

thewird

iTrader: (8)

Unless its a race car, run the primaries in the stock location. I would run something bigger on the secondaries in case you want to upgrade. Or if you have a good fuel pump, you can also turn up the fuel pressure but idle will suffer with ID1000 primaries and high fuel pressure.
