To start this out, thanks to everyone on this board for all the great information.

The goal is to get past 500hp to the wheels on 93 pump and methanol.

Here is my shopping list:

Coolingmist pump


1200cc/min FJO racing solenoid


FJO racing water injection solenoid driver. The driver will be controlled off of an output from my Hatech E8.
[couldnt find a picture]

Mallory 30-100psi fuel pressure regulator - i plan on running this at 100 psi


Coolingmist filter


I am going to run stainless lines from my tank -> pump -> fuel pressure reg. I will run the cooling mist lines from the regulator forward to the solenoid.

I forgot to take pictures of my tank but basically it is a stainless tank that is mounted where my passenger side muffler used to be (i run a single exhaust). I have yet to weld the back on it as i am waiting for my pump to get here so i can build a nice recessed spot for my tank. It looks like the capacity will be around 3.25 gallons.

I will be having Steve Kan tune it nov 29-30.

Current setup:
Fresh rebuild and HBP
ASpec 500r turbo/manifold ( i forgot the exact turbine a/r but it was the biggest they offered)
4" exhaust
walboro pump+aeromotive fpr
550/1680 injectors
FMIC
Haltech E8

A few things i have not quite figured out/questions:
1. Will my fuel pump be enough? I know JRat made 450whp with a single walboro. I believe howard is using a bosch 044 with a boost a pump (correct me if i am wrong). If i need to add more pump i will go to dual walboros, with one pump going to each rail.
2. Who makes the best bang for the buck fuel pressure gauge? I would like to add one for my gas setup and one for my meth setup.
3. I am going to build an access port through the floor of my trunk to fill my meth tank. I plan on probably taking the car to the drag strip on occasion and maybe a trip to a road course. What precautions do i need to take in designing it so that i pass tech inspection?

Please post any comments/suggestions you might have, it is all appreciated.

Thanks

Lee

 

Here is some of the progress so far:

I have the majority of the tank welded up:



The tank was about 3.5 gallons before i cut the back to fit the pump in there. I think the whole pump mounting caused me to loose about a gallon of volume. I am going to cut an access port in my trunk floor to get to the fill cap. There is a vent mounted to the top of the tank with a tip over valve in it. Hopefully i will never utilize the tip over protection.... The tank mounts where the passenger side muffler used to be. It tucks away pretty cleanly. Very little is visible bellow the bumper. The lid is a summit racing fuel cell replacement cap. The tank is ss304. To give you a rough idea of the mounting of the pump:


All the stainless lines are -6 hose. A line 1/4 inch line will be run forward to my FJO solenoid.

My fuel pressure regulator will mount to the side of the tank near the underside of the car:

 

first off... congrats on assembling what will be a super system.

1. Will my fuel pump be enough? I know JRat made 450whp with a single walboro. I believe howard is using a bosch 044 with a boost a pump (correct me if i am wrong). ////////////////////// i assume you are referring to the pump for your pumpgas...... i run a nipon cosmo pump w a Kenne Bell Boost A Pump (BAP). the BAP is set to raise V to the pump only in boost and is set at plus 20%. when i added my alcohol (around 1200 CC/Min w the AlkyControl and 1400 w the FJO) my duty cycle dropped about 20 points, from high 80s. prior to the alcohol my 850/1600s were close to 90%. i do digitally log fuel pressure and can tell you my pump/BAP delivered constant pressure.////////////////////

If i need to add more pump i will go to dual walboros, with one pump going to each rail.//////// i really like the BAP. less plumbing etc///////////


2. Who makes the best bang for the buck fuel pressure gauge? I would like to add one for my gas setup and one for my meth setup./////////you want a pressure sensor so you can log pressure.... FJO makes good ones////////////////
3. I am going to build an access port through the floor of my trunk to fill my meth tank. I plan on probably taking the car to the drag strip on occasion and maybe a trip to a road course. What precautions do i need to take in designing it so that i pass tech inspection?/////////it is outside your body so it should be o k//////////


i don't see a return line (to the tank) from your pressure regulator. as per my thread... you will need one.

 

pretty narly looking setup you got there

 

There is a return line, didnt have a chance to plumb it. I got sick of dealing with the braided stainless lines. I am absolutely terrible at assembling those hose ends.

Im not sure what is causing my welds to oxidize so bad. Should i be using a higher flow rate of shielding gas or a larger cup on the tig torch? Im kinda sick of having to grind off all the nasty oxidation.

 

Update:

 

Im to embarrassed to show my tig welds for the bung to hold the injector. Lets just say i need to do a bit of grinding and chase the threads with a pipe tap....

I forgot to order a 90 degree hose end so i will have to wait til next week to get the tank mounted. I'll probably cut the access hole tomorrow. more pictures to come.

 

Very nice work! where did you find the 1200cc solenoid? The biggest one i saw on there parts list was only1000cc?

 

He is now at 554whp. Single Walbro and one M10 nozzle using ethanol (denatured alcohol).

 

congrats. you have assembled a system that will eventually be on any serious single turbo FD.

the essential components:

a solid state controller for the solenoid/fuel injectors featuring the ability to tune off an X Y grid of rpm and load.

properly engineered injectors... FJO invested a year in designing/testing their units.

pump. while i replaced my FJO Shurflo pump w a Bosch i believe it is highly probable that the Shurflo would have worked fine after modifying the system to include a pressure regulator and return line. they are essential.

adjustable pressure regulator. after a lengthy survey i picked the Weldon unit as it is 100% meth compatible and is adj to 200 psi.

return line. this is essential so the pump does not cavitate and create gas in the line when the injectors are not venting injectant.

i am not up on what you can do control-wise using your Haltec. i do know the FJO control module is small, relatively inexpensive and works.

since i reengineered my system to include the reg and return line it is almost invisable.

again, congrats.

i ordered the solenoid from horsepowerfreaks.com

The output of the haltech is a pwm out. You can select the frequency and control a value from 0-100%. It will take some experimentation to get things setup correctly.

 

question about running the meth line: Should i be wrapping the line in anything? I currently have it tied along the stock fuel hardlines. It seems like there could be some abrasion issues.

 

~ How much power will one 1200cc injector solenoid supports with your setup?

I'm trying to peice together a kit also, and like the idea of running one injector over two.

Also , the solenoid driver comes with the injector right?

 

The solenoid driver is extra. It was around $100. Still the best bang for you buck system. I looked at coolingmist, but their s-hsv valve can only handle 10gph whihc is 650ish cc/min.

Im not exactly sure how much power my 1200cc injector will support. Hopefully i can get to 500. If my tuner does not feel safe going that far i will have to add another injector. I'll probably just add another 1200cc injector so that if i go totally insane i have enough meth to run a whole boatload of boost....

 

If you have the Water injection controller (PN CW10010) do you still need the driver?

I'm wanting to do something very similar to your setup but I am running a PFC wich won't control my AI system.

I am planing on going with the Alkycontrol pump sence it seems to be high quality from their discription.

Is your FPR 100% meth compatable?

Is possible to run a braided line to the solenoid? Just seems like it would be more reliable.

 

I believe that if you run the water injection controller you do not need to run the solenoid driver. The driver is only if you want the ecu to control it.

I did not look at the alchycontrol pump but i know coolingmist has a 100% meth compatible pump.

The regulator is meth compatible. Only goes up to 100 psi. if you want to run higher you will need a different one. Howard is running a weldon regulator.

The fitting on the solenoid is for the plastic line. Im sure you could rig something up, or atleast run braided stainless line forward to the engine bay and convert to the plastic lines.

I think i am going to get some rubber hose and sleave the plastic lines so that i dont have any abrasion issues.

 

What size fuse should i be using? I couldnt find the info on the FJO solenoid. Right now i have a relay that has 2 outputs: one to the solenoid driver box and one to the pump. The pump needs 10amps. So i need 10+ how much for the solenoid?

Thanks

 

PUMP power should be fused for 15 amps.
WATER INJECTION CONTROLLER power should be fused for 10 amps or 20 amps if the
optional WideBand is connected.


^^^copy and pasted from install manual.^^^

 

I've got a question about your FPR, Sense it is only adjustable up to 100psi,if your pump operates at 120psi will you only see 100psi at your nozzel?

 

1. I saw that in the manual, but that is for the controller, not the solenoid driver. I think I will assume the solenoid driver pulls the same current as the controller if i can not find correct specs soon. i dont have the FJO pump. i run a coolingmist pump that says it needs a 10A slow blow fuse.
2. I will only run 100 psi to my nozzle. The entire point of running the regulator is so that the pump never hits its internal pressure regulator that causes its to shut off until the pressure drops below a certain level. I should see a constant 100psi at my nozzle no matter what. If at some point i want to run higher pressure i will need a new regulator. my pump is rated to 150psi i believe so i should be safe running upto 125-130psi. I will see what steve kan thinks of the situation when he comes and does my tune at the end of november.

 

If you are running 20 psi of boost would you not need to be running 120psi through hot fpr to equal out and actually have 100 psi at your solenoid?


Hopefully not, because the price of the mallory for is so much cheaper than the weldon

 

I am not planning on running rising rate fuel pressure. My map will compensate for that. I will loose a bit of flow at high boost pressures but i think my large injector will make up for it. if not, time for another injector.

update:
get everything plumbed. powerd on the pump and it leaks. joy... time to drop the tank so that i can tighten the fitting. i sure as hell am going to pressurize the damn thing not mounted to make sure no leaks... its a bitch to get up there.

one of the random leak spots is my low level float i got from coolingmist. i think it is defective. i might just weld the damn hold shut and figure something else out.... seems like the design is prone to leaking.

ill post some pics when i get home

 

Take a look at these, Iplan on using one ofthese 2

I haven't looked at collingmists level float yet so it may be similar.

 

mmm i might buy one of those low level switches. i also might just cover it in some sealant.

pics:




Hopefully i can get all the leaks tightened up and ill do some flow test this weekend.

 

Looks nice Iwas having a hard time visualizing your tank in place but now I get it have any pix from inside the trunk? is your pump head actually leaking or is just leaking where all the fittings connect?
