my third AI system
 

after doing lots of research i decided i wanted to help out my pump gas w as much methanol as possible.

looking over the available options in 2003 i decided to go w Julio Don's Alkycontrol system. Julio had zillions of high value threads/posts on the most important AI forum on the net... TurboBuick. the Alcohol Propane and Nitrous section had over 200 PAGES of threads back in 04.

i was not disappointed. i ran two M15 nozzles, around 1300 CCs/Min and made 507 SAE rwhp at 20 psi w the Alkycontrol system.

BUT

it is a pump/nozzle deal and as such is fine for dyno and drag racing and is not able to bob and weave during transient throttle situations, like in a corner at Road Atlanta.

i discovered FJO in 2009 and they had what i needed. fuel injectors running on an X Y grid w RPM and Load.

i call it HD AI.

and it is awesome. i ran it in 09 and 10. you just dialed in the exact amount of alcohol you wanted in 156 cells!

i did have to mod it a bunch to run 100% meth. i had to install a return line and pressure regulator. once i did that and switched to a Bosch 044 type pump all was super.

until this year.

the FJO module failed. not a surprise as everything else has failed since last Nov.

Kenne Bell Boost A Pump
Datalogit
Power FC

and now the FJO AI unit.

while the other items have all been replaced w new the FJO unit is no longer available.

which brings me to this post.

the executive summary:

since i have the pump, tank (4.5 gal), return line, adj Weldon pressure reg i am going to use what i have and

add two additional injectors to my elbow and drive them thru the Power FC. these 2 injectors will flow methanol.

i am now back to having AI being able to be precisely delivered... in 400 cells.

here are the details:

my objective is 600 rwhp SAE maximum.
max fuel delivery must be at no more than 85% duty cycle
i want enough spare fuel to run to 10.0 to one AFR (not that i plan to, i just want reserve deliverability.)


here's the numbers for those interested...

600 rw rotary hp

600 X 1.92 = 1152 CFM
1152/ 14.471 = 79.6 call it 80 pounds of air per minute
11.3 target AFR means it takes 80/11.3 = 7.08 pounds of gasoline
7.08/ 6.35 = 1.115 gallons gas per minute
1.115 X 116,090 (BTUs in a gallon of gas) = 129,429 BTUs to make 600 rw rotary hp.

primaries 2 X 850 = 1700 X .85 (duty cycle limit) = 1445 CC/Min

1445 = .3817 GPM X 116,090 = 44,311 BTUs from primaries

129,429 - 44311 = 85,118 (BTUs needed from secondaries)

i want 2000 CC/Min of Methanol (from experience this works really well w pump gas at 500 hp, knock under 10)

2000 = .5283 gal
.5283 X 57,250 (BTU in a gallon of meth) = 30,245

85,118 BTUs - 30,245 = 54,872 BTUs needed from two gas secondaries

54,872/ 116,090 = .4726 g of gas

.4726 = 1789 CC/Min


from the above it is clear:

i will run two Bosch EV14 1000 CC/Min conical spray pattern injectors in my secondary ports and two Bosch EV14 1000 CC/Min short body conical spray pattern in my elbow.

the Power FC is fully capable of driving each of the 6 injectors and we will simply tune as if no AI system is present.

i can vary the output if i wish of the meth injectors as my pump can raise the pressure significantly.

this appears to be a simple way to end up w an HD AI system.

i will report back when up and running. the injectors are on the way.

howard

subscribed. I was thinking about doing something similar with a PS 1000 not even a month ago. Great minds do think alike.

are you going to mirror the primaries or the secondaries with the AI injectors?

Very interested in seeing how you develop this setup with a Power FC before dropping cash on a full AI system.

Ahhhh innovation. I'm rootin for you.

"are you going to mirror the primaries or the secondaries with the AI injectors?"

since all 4 secondary injectors are the same... and the Power FC can drive 4 secondaries in addition to the primaries...

we will just plug in the appropriate lag and delivery from the secondaries and tune as if we had 4 injectors, it is just that a bit more than half of the 4 secondaries will be feeding the motor meth.

i say more than half as we will be running the secondaries at higher static pressure.

Awesome development... I would very much like to do this

FWIW, just make sure there is no water in the methanol, otherwise the injectors will rust . . .

:-) neil

the hardware arrived today. i am impressed w how small everything is. small is good. here's a comparo. an old style Bosch 1600 injector and the newer EV14 in the 1000 delivery size.

the other 2 smaller new style are also 1000 cc but are "short" /33 mm between O rings. they ought to fit very nicely on my elbow.

i swapped in the secondaries a few minutes ago and hope to go for a drive tomorrow. i will run the car up to Beyond Redline next week to have the meth injectors fixtured.

First off sorry if my questions seem a bit uninformed. My current knowledge of a lot things is limited at this point.


Hc I'm curious as to why you went this rout? Are there no other systems out that have the kind of control your looking for or is it that this setup will work well for your needs?

From my current understanding you'll be gaining control through the load range (400cells vs 156) but loosing some control over the initiation point?

I ask because while my endeavors with a rex are still probably a few years out I have some ideas of what I want to do. One of them being AI with 100% meth(shooting water into a motor just doesn't sit right with me) and like you I would like more control over it than what is basically like turning on a garden hose.

Also one question that's a bit off topic. From some of your past threads I understand your running a healthy amount of meth(replacing 20-30% of your fule with meth). Are those levels needed to hit your goals or are you just of the mind set that the more meth the better?

Thanks for any info.

some excellent questions RD.

"...why you went this rout? Are there no other systems out that have the kind of control your looking for or is it that this setup will work well for your needs?"


your "garden hose" description of pumpspeed/nozzle AI is correct and is the initial reason i jumped on the FJO setup as it is entirely different.

as most know, fuel injection/computers revolutionized our auto engine performance.

fuel delivered everywhere on the map to the Ms.

neither a carb or a pump/nozzle can keep up w transient throttle.

fuel injectors run by computers can do it perfectly without breaking a sweat. and the FJO AI system works like the computer driven fuel injector.

and it did work, providing 156 cells where you simply dial in whatever % of max delivery you wish. just like our Power FCs or the OE computer.

it did work until it didn't.

after 5 years of no problems i have been plagued w the loss of my Kenne Bell Boost A Pump, Datalogit, Power FC and now my irreplaceable FJO AI setup.

since FJO sold out to Holley and Holley in their infinite wisdon is un-interested in continuing what is hands down the best AI system available it became time to innovate. (there are no other similar systems available)


"loosing some control over the initiation point?"

my secondaries enter the picture as i cross into boost. that is where i also chose to start my FJO so the initiation point is not an issue.


"running a healthy amount of meth (replacing 20-30% of your fuel with meth). Are those levels needed to hit your goals or are you just of the mind set that the more meth the better?"


all i can tell you is that at 500 hp w 1400 CC of meth knock dropped to under 10. this suggests one happy motor at 500 hp on 93 octane.

in addition not only is the motor happy inside as to combustion but take a close look at the (uncleaned) rotor that came out of the motor after 4 years of duty!

http://img220.imageshack.us/img220/3706/58558352.jpg

4 years--- no carbon. building rotaries i see boatloads of motors and upon disassembly i am still shocked at how much carbon accumulates. thick coating on the rotor faces and lots in the apex and sideseal grooves. take another look at my 4 year old rotor.

much of this has to do w meth.

finally, meth just has superior qualities to gasoline, and this includes racegas.


a 400+ degree higher autoignition temp
stratospheric octane (all numbers are guesses because octane is measured at standard temp and you can't get the charge air down to std temp as the meth cools it so much)

huge cooling gas has 900 BTUs of cooling per gallon, meth has 3340.

so yes, i want to run lots of it.

howard

What is that on the right?
Would this system work only with pure meth? Or would a 50/50 meth/water mix be viable also
Are you planning to write a DIY after finishing the project? Curious about your pump/fail-safe too

item on the right is an FJO purpose built water/meth solenoid-injector. it is a 700 cc item. i ran 2 700s for four years and last fall swapped in 2 1000 cc.

the FJO works w water or meth or a combo

yes, i will put something together.

no pump fail safe. i run a Bosch 044 variant. (it is external to the tank) i plan to use my Kenne Bell boost switch... i will just Tee into it. it generates a signal to the BAP to raise V to the gasoline fuel pump. i will use the same signal to trigger my Bosch meth pump relay.

Fallowing another HC thread.

Very interested as I am looking to get AI on my build. Seeing the PFC controlling the AI injector(s) seems to be a clean set up.

My goal is 400 rwhp then step up to 500 rwhp on California 91 pump gas.

hey Howard, is Holley now offering the previously FJO WI system?

http://www.holley.com/HolleyEFICatal...?pageNumber=18

looks similar

aren't these injectors offered in a size that fits the stock secondary rail? i though i read that somewhere. that's be a sweet setup, then keep the stock fpr and have a really simple setup. not good for 500 hp but 400 would be fine seems to be accepted

"is Holley now offering the previously FJO WI system?"

such a travesty. FJO designs a lights out system and doesn't market it. (not knocking FJO, they design stuff and then others rebadge it... so they elect not to retail)

so they then sell out the ECU (yes they make a stand alone engine mgt system) and various other items to Holley and Holley, in their infinite wisdom decides to not sell it as a stand alone AI unit, rather incorportes it into the FJO ECU.

i called them a month ago and told them they were sitting on the best AI system in the world, just knock out the module.... no. no interest?

oh well.

(yes you can buy the solenoids and pump but without the module they are useless.)


"aren't these injectors offered in a size that fits the stock secondary rail?"

not sure i understand your question.

i chose to deal w Fuelinjectionconnection.com. John, who may be the owner knows FDs backwards and forwards and was way ahead of me.

he sent me two of the new tech Bosch EV14 injectors that were fixtured so they dropped in my secondary rail and 2 EV14 injectors that were short body. my thinking w the shorter injectors was that space around my elbow is limited so go w the smaller size. (tiny--- only 33 mm between O rings!)

all 4 injectors deliver 1000 CC at 43.5 pressure. the shorties are run off a separate pump and of course deliver nothing but methanol. i probably will run them at around 60 psi static to juice up the volume a bit.

my Boost A Pump has a Pressure/Boost switch. it completes a circuit to my BAP as soon as it reads boost. i (today) will Tee into it and use it to start my alcohol pump.

in addition, yesterday, i converted my meth system pressure sensor so it will feed into my Datalogit. i will be able to log my meth pressure to verify it is turning on the meth pump and also verify system pressure.

my meth adj regulator is back near my tank and pump. i will use a length of brakeline to feed MAP back to the pressure regulator so i have consistant net pressure to the regulator just like our gasoline systems Tee into the manifold.

i was saying that these injectors would be a simple solution instead of changing the secondary rail, fpr, lines, and injectors. when just the injectors could just be changed...

Ah, you mean for general use (unrelated to AI)?
Would be great if it's the case

well in this application as well, the 2 additional 1000cc's could be added to the elbow like howards setup. its what im thinking about doing now since fjo is no longer available. i like that i can tune as if it(ai)weren't even there.

"i can tune as if it(ai)weren't even there."

yes

"these injectors would be a simple solution instead of changing the secondary rail, fpr, lines, and injectors. when just the injectors could just be changed... "

o k, i finally get what you are saying. i couldn't figure it out because it was too simple:)

what a great idea. i suggest you check w John on it. i guess we would be looking for the new style EV14 w dimensions similar to out secondaries at a higher output.

i have been thinking of changing out my primaries (850s) to the EV14s.

Power FC owners are confronted w a dilemma. rich idle from bigger primaries and an inability of the PFC to decrease ontime past a cetain point and a need to put more fuel thru the motor.

of course now w the 2200 secondaries you could skinny the primaries and end up w a better (leaner) idle but...

there may be something to be said for delivering more fuel thru the primary port. the primary on the stock FD is smaller than miniscule. given a stock port the smaller primary makes sense. i do a significant amount of work on the primary port, opening it up, and i want lots of fuel delivery going thru it for enhanced atomisation.

on another matter on my meth (AI) pump trigger i decided to go w another Hobbs switch rather than to Tee into the BAP switch...

after a bit of unsuccessful searching in the Power FC section for Four Secondary Injectors i checked w Luke and w RotaryPerformance to find both suggested i take the strain off the PFC drivers by re-installing my FJO Peak and Hold Injector Driver.

both said that the ECU might work w 4 but the additional heat could shorten life. given my recent experience w blown up elecs i elect to play it safer.

any experience out there w the Power FC and 4 secondaries?

also, talking w John at Fuelinjectionconnection... he has a wide array of EV14s for the primaries but they require a new rail as they are top feed only.

I find it fascinating that I stumbled on this thread this morning, and was just thinking about something similar to this over the weekend.
I about about to put a bridgeported engine in my FC, and am definitely going to use alcohol injection. I will be using occasionally for drag racing andn will be driving it on the street, but my main goal with this car is as a track car for NASA HPDE/time trials. I had been seriously looking at the alkycontrol system since I have seen it on BDC's car and was impressed with it. The thing I was worried about, though, was transient throttle conditions seen around a race track. I was searching over the weekend and found your thread about the FJO system you installed a few years back and it showed that my fears were well founded.
The FJO system seemed impressive and just what I was looking for, but I though "I wonder if I can just use my Haltech?" I currently have a E6X. I have looked into it, and each of the channels can drive 2 different 4 ohm 1A in parallel. This would allow the addition of the 2 methanol injectors. There's obviously some things to work out, but the fact that you are pursuing something similar gives me hope that my idea isn't totally out in left field. I'm going to look into a few things and will probably back with some more thoughts/questions (assuming its ok with you for it to be in this thread) and will most certainly be following your progress in this thread.

After more research, it appears that 100% meth is illegal in all forms in NASA time trials. I have a question in about e85. If that is legal, which it really should be, then I am going to start persuing a setup like what you have planned up, but instead using e85. I realize its not as good as methanol, but NASA is one of the main reasons I am building this car, so methanol is out. If e85 were more available I would totally convert it to run only e85, but oh well. I want something that I don't have to modify depending on where I am running it; I just want to tune it and be done, other than maybe adjusting the boost when on the street.

One question, though - how are your injectors going to be wired? I'm not familiar enough with the Power FC, but are you just running the meth injectors in parallel with your secondaries? Is there a single control signal for the secondaries, or is there a signal for each injector? If that is the case, which injector signal would you tie into for the meth injectors? Will there be an issue with them being further upstream, or is there a provision for adjusting that somehow?

Sorry for all the questions, I'm just really interested in this and trying to figure out what you are doing since you obviously have way more experience at this than me!

last time i checked NASA prohibits running any AI injectant that can burn. a 50/50 mix can or cannot burn depending on the temperature... so it is probably o k.

the secondaries are wired parallel not series. i am wiring one AI injector off the front sec and the other off the rear. there is no issue as to timing as electricity travels at the speed of light.

i just finished my boost switch for the fuel pump. as delivered it closed the circuit at 4 psi. since it is adj i changed it to trigger at .5 psi.

Yes, 50/50 meth/water is allowed. It specifically states that you cannot inject methanol/alcohol in above a 50% concentration. I am trying to make the case that since e85 is allowed as a race fuel it should be allowed to be injected, especially when using a setup such as this that is actually safer than the stock fuel system, but I doubt it will go anywhere. Oh well. As it stands, I have a hybrid turbo so I am not making enough power to justify a full meth system anyway (400 WHP MAX). I will probably get a normal cheap 50/50 system just as added insurance until I finish upgrading everything else.

What you described for the wiring is actually exactly how I had envisioned it as well. The issue with them being further upstream wasn't due to extra time for the signal to get there, but because it is physically farther up the intake it will take longer for it to get there. I was under the impression that the secondaries kicked in momentarily sooner vs. the primaries to account for this and wasn't sure if that would be necessary for the meth injectors that would be even further back. I guess at those air speeds it doesn't make too much difference, plus its still a vast improvement over the "garden hose" method.

Sorry for this being a bit off topic HC but since you seem to be one of the leading minds around here on AI I figured I'd ask you.

Can 50/50 mix be run through a normal fuel injector without any ill effects or will it lead to problems and failure of the injectors?

It turns out there is already an e85 station in Temple (opened a few months ago) so I will almost certainly be switching to e85 whenever I get the money to do it properly (next year sometime).

As for running a water/meth mixture through fuel injectors, I would be a bit wary about that. I have no firm data or experience to back this up, but I would think the water could cause some corrosion problems with them. Obviously you should wait for a stronger answer, but I wouldn't attempt it until you get an affirmative, which I would doubt will be the case anyway.

"Can 50/50 mix be run through a normal fuel injector without any ill effects or will it lead to problems and failure of the injectors?"

the EV 14 is all stainless steel w the exception of the spring. being Bosch i can assure you it is the highest quality SS. i would not hesitate to use it and would look at it from time to time. the injector is not expensive and changing it out every couple of years just to be conservative shouldn't be a big deal.

remember, you are saving money not having to call an engine builder:)

BTW, took apart a Coolingmist 50/50 mix AI motor a couple of days ago. the rotors looked almost like they hadn't been run.

don't underestimate the cleaning power of water or meth and the important contribution they make to longevity.

howard

I was wondering if something of the sort could be done....very interested to see your results.

Good to know about the injectors, thanks for the quick update.

a good day for me is when i learn something

as you may be aware, i am in the middle of re-tooling my AI system since my irreplaceable FJO system decided to check out.

it should be a win for me and for Power FC owners as it uses the Power FC to drive an additional pair of new generation Bosch EV14 injectors in the elbow to spray methanol. (you could use water or a mix too).

i premise many of my calculations on an empirically derived relationship between rotary rwhp and airflow. if you know the airflow and AFR you can calculate fuel and lots of other interesting numbers.

it appears i have omitted a key additional deduct going from gross fuel to net fuel:

that factor is injector Lag, often also referred to as Deadtime.

i have read about it many times and we all input lag numbers when we set up our Power FC Settings 5 page.

i guess the lightbulb never quite turned on for me until it was brought to my attention by a board member and after i did some calculations...

i referred back to a previous run for numbers. here's how it played out...

507 rw hp SAE
12.0 AFR
75.1 injector duty
20 PSI

injectors:
primary 888 (RC flowed)
secondary 1650 (RC flowed)
secondaries run by an FJO Peak and Hold converter
Supra pump run by Kenne Bell Boost A Pump at 20% Volt gain

AI
Net delivery of 1128 CC/Minute of 100% methanol at 20 psi



let's now try to quantify the amount of fuel loss from LAG/Deadtime

507 rw rotary hp X 1.92 = 973 CFM/14.471 = 67.24 pounds of air per minute

at 12.0 AFR.... 67.24/12 = 5.603 pounds of gasoline per minute

5.603/6.35 (weight per gallon gas) = .882 gallons per minute

.882 X 116,090 (BTUs in a gallon of gas) = 102,448 BTUs to make 507


BTUs from AI system

two M10 nozzles. Gross deliverability 1262 CC/Min. at 20 PSI boost X .89 (reduction due to manifold pressure) = 1128 CC/Minute Net

1128 CC/Min = .298 Gallons per minute X 57,250 (BTUs in a gallon of methanol) = 17,060 BTUs from AI

102,448 (BTUs to make 507 hp) - 17,060 BTUs from meth = 83,388 BTUs needed from gas to make 507.


BTUs from gasoline

According to my Gross Deliverability (5060) times my duty cycle (.751) i was nominally at (3800 CC) /116,438 BTUs.

116,438 - 85,388 = 31,050 the slippage from Lag/Deadtime

31,050/116,438 = 26.6% deduct


i will be off the board in the wilds of Wyoming this next week while Beyond Redline fixtures my elbow. i should have it the following Monday and hope to be on the dyno that week.

it will be very interesting to acquire some additional data as to Lag/Deadtime.

Lag/DT will vary w re to RPM, ontime, battery voltage, type of injector, fuel viscosity/temperature but from my calculations it may be a really important factor to crank into fuel system requirements as far as getting to NET Fuel Delivery.

injectors generally come w Lag settings to compensate so proper fuel is delivered throughout the range... so the settings portion is handled.

my concern is that when figuring fuel requirements perhaps another 20-25% needs to be added so as not to run short. if that number is in the ballpark it is an eyeopener.

comments welcome.

Any progress on the hardware side, Howard?

here's the elbow w fuel injectors...

http://img17.imageshack.us/img17/6803/ev14elbowd.jpg

should be running in a few days. BR needs to find a couple of 90 degree fittings and mail it to me.

howard

Hi Howard, I was just wondering how you were getting on with this? I've been following this thread and several of your other threads quite closely. I also had a couple other questions, might have missed it elsewhere but what kind of tank are you using for the meth? I'm assuming with the quantities that you are running that you may have had to fabricate one rather than use say the washer tank? The cleaning benefit of water/meth injection has been well documented throughout your threads, but would you say that an engine that already has some carbon build up would experience a removal of that carbon, or simply that no further build ups? I ask because I use my FD as a daily as well as occasional track car, but live in the suburbs of a city and as such there is a fair amount of low speed driving which I hate because of what its doing to my car! My motor is less than 8k old following a rebuild. I do try and redline her as often as possible though, much to the annoyance of many suburban Greater Londoners!

happy to update:)

i did expect to be running last monday but upon startup it was clear that the motor was only running on the rear rotor.

(front EGT 110 degrees F, rear 550)

white clouds out the tailpipe.

i figured it to be a primary injector and eventually swapped them between the rotors. since the front rotor continued to not run i eliminated the primaries after checking wiring. (which was a completely unbuthered new harness)...

i then checked ignition and found all four plugs were firing.

i did a compression check and a coolant pressure check and found both to be perfect.

the next item on the list will be to check my new EV14 secondary injectors. it could be the front injector is stuck open..

i did take the last couple of days off to build a customer motor but will revisit my car either today or tomorrow.

as to fuel cell... check out my sticky post for pics and specs. i am very happy w it. i will encase it before doing the Texas Mile.

you are correct to be concerned re carbon buildup. you should not be running the external oil pump if it is sourcing crankcase oil and of course you should be premixing 2 cyc oil.

both water and meth will clean a carboned up motor.

good luck,

howard

Howard, any update?

the problem turned out to be my Power FC. (new July)

the relay triggering my meth pump was replaced by the shop and it did not contain a Volt Spike suppressing diode or resistor. as a result i have lost 2 Power FCs, a Kenne Bell Boost A Pump, Datalogit and the FJO meth AI module.

the (two) Power FCs have inoperative front primary injector drivers and are being repaired by Apexi. a friend is loaning me another Power FC.

i am replacing the relay and will add a protective MOV before all my solid state items.

do not ever install a relay in your FD unless you are sure it has Volt Spike protection.

howard

i'm a little curious why you don't just run solely on E85, it simplifies alot of the additional failure points and nets the same(well better) end result. you just need a more stout primary fuel system.

of course then it wouldn't be in the AI section. :)

i dunno, it just gives full resolution and control over an alcohol based system without the clutter.

Howard,

I have some doubts regarding spikes from a relay could knock those systems out. Almost all switching systems have its own spike suppression circuitry inbuilt. It is unlikely those parts were badly designed - spike suppressing and device protection are well taught to all elecronics engineers during their training.

For example, multiple spikes from as fuel injector is far more frequent than a single short relay coil expecially those FJO solenoid switches very large current spike during the peak strike/release period.

Unfortunately I don't have an alternative explanation why those part failed.

I too am curious as to why not E85?

"why you don't just run solely on E85"

all of your points are valid re E85. my problem is there are not enough E85 outlets in and around Wisconsin. meth is easily bought/stored and it is only used when the secondaries come into play.

Hi Richard,

nice to hear from you.

"Almost all switching systems have its own spike suppression circuitry inbuilt"

you are generally correct re spike supression.

the pump relay that came w my FJO setup did have a Diode and for a number of years i had zero electronic failures. at some point the shop where i tune replaced it w a relay with no spike supression.... no diode, no resistor. that does coincide w the succession of electronic module failures.

2 Power FCs
one Datalogit
one FJO AI module
one Kenne Bell Boost A Pump

i tested my original relay and found it to be operative however i am not going to gamble and should receive today a new Beck Arnley relay with a Diode.

i also plan to add a MOV (metal oxide varistor) in front of all my modules for added protection. V24ZA50P.

given the significant number of failures it is probable that i do have a V spike issue. there could be a few other culprits in addition to the relay...

i have been dynoing w a battery charger hooked up at 10A. it is possible to induce a V spike from a charger.

there is a (slim) possibility that i have a constant continuity problem in my primary circuit. this could come from the alternator or any slightly loose connection. i did change to a higher output alternator prior to my problems.

for me, the relay is the prime suspect.

howard

update:

i have both Power FCs at Apexi for fixes and a friend is sending me his Power FC so we can move forward. a new relay is in place and i should receive the varistors today.

meanwhile i did some additional research on my meth pump (Bosch 044 variant) and have decided to look elsewhere as it falls on it's face around 80 psi.

i will be going back to a gussied up Shurflo probably. the 1.8 GPM open flow pump will run two Bosch EV14 1000 cc/min injectors. it will be set at 86 PSI static and will need to work to 116 psi (30 psi boost).

the EV14 injectors will work fine to 8 Bar (116 psi) and will deliver approx 2800 CC/Min of meth.

here are a few pics/comments:

http://img7.imageshack.us/img7/6297/001tlyg.jpg

you can see 3 items in the pic... one of the two fuel injectors that will deliver the meth. (the other is underneath at 6 o'clock)

my adj Honeywell boost switch on the firewall. it is set to trigger the meth pump at 1.5 psi boost and is tapped in to the UIM.

a stainless steel 3/16 brakeline that connects the adj meth pressure regulator and MAP from the UIM. the regulator is in the rear of the car by the pump and tank.

while this might look like a mish mash it does show an important component in the center of the picture... a meth pressure logger/sensor that is hooked into my Datalogit. i consider logging fuel pressure and meth pressure essential.

my Weldon meth friendly adj pressure regulator. located near/above the driver's side half shaft. it features a return line to the meth fuel cell and is plumbed in to the engine's MAP.

just a brief update. the system runs very well and is easy to tune. i made 514 SAE rwhp at 24 psi and the motor was way rich. once properly/fully tuned i see a happy motor at 550 and 26 psi w the Borg Warner S300 63.

Awesome!

Didn't you blow the motor while getting it tuned with this? Seems AWFULLY complicated for less than optimal results...

Updates?
