finally made the switch, took railguns advice and bought the pegasus fuel sock custom made and adapter for it, custom fittings. hope you like. very impressed with the results
force sx fuel pump
nickel plated the fuel pump bracket thingy, dont know the name of it.

I considered doing that same setup but I think 3 supra pumps will work better for my 20b setup. I think that 3 1000cc primaries and 3 2200cc secondaries will work best. I wouldnt mind running one pump especially for simplicity sake but i dont know if it would handle that much fuel.

These are a key component.

In what kind of setup? Just as a pair of secondaries?

So here's a question for those fueling gurus...

Not taking wiring, cost or the like into account, what would those folks recommend? A pair of the 2000s or four 1000s? For lower duty cycles, eg just getting past the transition where the secondaries start to fire, would you think you'd have better tunability (sp) with the smaller injectors? Similar to having too large of a primary and not being able to really get that fine of control over them. Yeah, you're still dumping 2k cc worth of fuel, but I would think a 1000cc injector at, say, 20% duty would be better than a 2000cc injector at the same. Maybe for the ID injectors, it's a moot point.

Maybe just six in one, half a dozen in the other....doesn't really matter?

Laz, nice solution there.

TJ,

I believe there are some that use the stock lines as twin feed lines and run another for return. Though, depending on your goals, that may not be the best way to go. Personally, if you're going to redo your fueling, it's not that expensive to run new lines...easily less than 10% of the entire setup cost. It can sometimes be a little time consuming depending on your proficiency level in actually doing it and how you want to run and secure them.

No... they work well in the primary spots too with a base of 60 PSI. These injectors aren't your average run of the mill injectors. Their spray pattern has been refined to allow smooth idle.
Actually Railgun, you know more about this than I do. You have considerably more experience with it.
I am using your experience to my advantage.

Railgun

Heh...I wouldn't say considerable. I do know that the ID injectors are pretty bad *** in terms of spray pattern, but the sheer size, in particular the primary spot, would suggest that they would cause some small idle issues with such a low duty cycle. I'm using 1000s as mentioned and they work really well. I would seem that doubling that would potentially cause issues just because of how much they'd flow. But I digress.

I actually have a rx7 here running 4 ID2000 inj on pump gas. It idles at 13.4:1 w/o any issues. This is on a haltech Platnium. NOTE to others, 4 x ID2000 won't work well on PFC due to the ECU limitations

pluto what did you do to get it to idle at 13s, timing? I tried and it will lean out and shut off I have 4x 1600s

Injector Voltage Map?

The ID2000's are a much better injector, better responce, better spray pattern, and high impedance. But are $240ea.

There are a few cars I have found 1.6-2.0l able to idle these injectors at a reasonable A/F.

http://www.t1racedevelopment.com/en/...-injector.html

I'll be changing my primary 1600's to these in the future.

pluto

your suituation is different, you are running a microtech compound with poor spray pattern 1600cc inj. I believed the 1600 can only go down to 1.3ms so it will be hard to get descent a/f idle. Microtech doesn't have as fine of resolution compare to other ecu. They were never meant for street use but is a good ecu for drag racing. They are slowly getting better but is 90s technology compare to other ecu on the market.

Steve was the red car on e85 or 93?
those big injectors fired right up and idled great I was surprised,

five o injectors has a good price on them, I've had great luck
with his injectors

http://www.fiveomotorsport.com/impor...uel-injectors/

he has the bosch ev14's in 1000, 1200, 1700 and 2200cc

pluto

the red car is running on 93 pump. I guess five o is an alternative but I personally don't have any experience on them and I don't believe they are the same. Even 1600cc has several variety but flow characteristics and impendance are different. I will stick with ID injectors until proven otherwise

I didn't clean my fuel tank on my 87 TII before I made the E85 conversion.
I have run 3 tanks of E85 through the system.
Yesterday I decided to take a peek at the fuel filters expecting them to be coated with the funk that some of you have described.
They filters were as clean as they were when I put them in there!??
Have tested all the E85 I am putting in there and it is actually 90% ethanol!
So far so good!

Maybe if you pour it on the street and light it with a match, but not in an engine. If properly tuned combustion temperature will always be at the upper limit for maximum efficiency. The whole point of burning a fuel is to make heat which is what makes air expand and push the piston or rotor. The real benefit of alcohol is lower intake temps which let you run more boost and still have the same compression temperature, i.e. before combustion, to prevent sudden detonation of the entire mixture at once (knocking) rather than a spreading flame starting at the spark plug.

Does a setup like this sound good?
Power FC
Dual Bosch Pumps with CJ-Motorsports Adapter
-8AN feed line to CJ-Motorsports Primary and Secondary Rail
ID1000 Primaries and ID2000 Secondaries with Aeromotive FPR@50-60 Base Pressure and -6AN return.

Anyone think that this would support 500-550 rwhp? Anything else I should change or add?

Glass man, sounds like a good setup, you can't beat the Bosch pumps. If you needed more fuel, you could go with 4x ID2000's instead, I'm sure they would idle a rotary without any problem.

I am running ID2000's in the primarys and my car idles better now than it ever has!

I'm sorry if I missed it, but what ECU are you running?

Viper GTSR

...X2*

So X 4 ID2000's in total?

RXTASY57

iTrader: (2)

I have a HBP and ID2000's in the prmarys.
My idle is at about 1600 RPM and 14:1 AFR.
Injector voltage is around .900ms.
I am VERY impressed with these injectors!

RXTASY57

iTrader: (2)

Oh! I'm running an old school Haltech E6K.
Boosting to 20 PSI now and 11.4:1 AFR (gas)
Took a look at my fuel filters and they are pristine clean! I didn't clean my tank before going E85 either.
My injectors are at about 80% duty cycle @ 20 PSI, so I think I will be maxed out at 25 PSI.
Might have to add a couple more injectors and get a new EMS (Platinum 1000).
Would like to run 30-40 PSI eventually.
I am also running straight meth injection which comes on around 12 PSI.
Starting to have fun again with my car! It's a beast!

Hey Bruce,

What fuel pump are you running? I have 4 of the ID2000's and curious how well my set up is going to work.

Also what turbo do you have nowadays?

Trots*88TII-AE*

iTrader: (11)

Hey Slammed, have you decided to keep your ID2000's now? I'm always stoked to see more people switch to E85. I really wish I could get it closer than 3 hours from me And even that station checks VINS! lame

Slammedblk7

iTrader: (7)

Well..I might as well, not everyone can justify spending 1k on injectors I guess. The closest E85 station is about 20 minutes from my house which is also caddy corner to my gym. Then, there is another station about 5 minutes from my job, so it makes all the sense to keep them and continue with E85. I have not heard of the stations checking VIN numbers and not sure what the purpose would be?

I did the math but, still curious of real world experience with the injectors and E85. I came up with 700rwhp with E85 around 95% duty cycle...
