OK Building my AI setup

I'll start with the peices I've already collected...

Pump ~$130


5 gal feul cell W/rollover vent. Also sumped in the rear.~$110




Mount for my cell ~$5 Picked up some steel from a local steel yard and I'm in the process fabricating it now. So far all I have is the base and I still have some trimming to do.

I ordered the Venom performance FPR

It is a risisng rate FPR from 20-125psi (perfect range) and can be manually adjusted up to 150psi. And most important it's 100% meth compatable.

Today I hope to complete my fuel cell mount as well as a mounting bracket for my meth pump. Then I'll have an idea of what AN fittings I'll need to order as well as how much braided line.

Well the cell mount is taking a bit longer than I expeted but it's almost done. And after staring at the bottom of my car from a creeper for 45min I finally figured out how to mount my pump. I don't want it inside the car for the obvious dangers of possible leak. So I cut and welded a bracket that will allow me to mount it under the car between the rear bumper and the fuel tank. I'll also be mounting the FPR in the same way. The will allow me to use very little plumbing from the cell-pump-FPR-cell with the only long line line going to the solenoid(s).

I'll also be fabricating a shield to protect my AI componets from any road debri as well as any fireballs my exhaust may want to cough up

I forgot to add the price of the FPR to post #2 ~$150

Update

Today I got the foundation for the cell completed. All I need to do for it now is fab up the straps.
Here is a shot with the cell in place.

Here is a shot ofthe pump mount in place but not bolted down.

This will give you an idea of how the pump will sit. It is now about an inch and a half higher.

Rear view before I raised the pump.

i think there are better places for your pump.

I'm glad you chimed in howard, did you ever get your setup on a road coarse yet? I'm very cueious to hear how it held up. And as far as pump location goes, I origionally planned on mounting it like yours in the link but it just seemed too cramped under there. I think my location will work just as well but we will just have to see. I'm also probably going to replace the rubber bushing on the pump's mounting bracket with some thinner ones to raise the pump even more, with that and a good sheild beleive my setup should perform well without any issues. *fingers crossed*

Quick question, I'm about ready to order the plumbing for "kit" but i'm not sure how big to go on the braided lines.

From the cell ---> pump --> FPR--> cell I was planning on running -6 line like most everyone else but the fittings from my cell and FPR are both -8.

So rather than run several reducers I'm wanting to just use -8 line for that part of the plumming, Anyone see ANY negatives to this at all? I really don't think it will make a difference but I figured I'de ask first.

BTW I plan on using -4 line from the FPR --> filter-->press sensor/logger-->solenoid

I'm not sure If I wanna use -3 or -4 for the breather from the tank,

Also is anyone putting a filter between the cell and the pump? That seems like itwould be ideal for long pump life but FJO does't show one in their install instructions.

dash is just bulkier... but i see no problems.

dash 4 is o k where you plan to use it.

i have dash 3 on my breather.

my filter is after the regulator before the pressure sensor. your location is a good one.

Thanks for the input Howard. I just received my FPR yesterday and Must say it looks pretty nice. I also ordered my first "stage" of plumbing. I'll update with picks sometime next week when my order from summit arrives.

Howard, do you have to have the fuel pressure gauge to run the pressure sensor, I noticed it doesn't come with a pigtail and was curious about how you wire it in.

Also fjo offers 2 boost control solenoids and I'm thinking I'll need the one with 3 ports . I'll probably give fjo a call later but was curious if you know wich one I'll need.

Btw I have a tial 46 mm wastegate

the AI pressure gauge wires in to the FJO AI module. it is monitored via the FJO program in my laptop. since it is part of the overall system the FJO AI system can react to a loss of pressure and shut down boost etc. as to the pigtail the FJO pressure sensors use a standard pigtail and i don't now recall.you can get it at autoparts stores or perhaps FJO.

i took a couple of swings at the FJO boost controller which is part of the FJO AI system. we were on the dyno and time was precious and we were unable to get it to work. i reinstalled my Apexi AVC-R.

perhaps i will revisit the FJO boost control because it is capable of directling a 3 port solenoid that may have better spool than a 2 port.

after draining my cell i removed the anti slosh foam. it came w the Jaz cell and was considered to be fairly good w meth. after 2 seasons (and being drained off-season) part of the foam was disintegrating. i will clean my system and use meth compatible foam for next year.

I spoke with a rep at fjo about there boost controller and they said they were having issues with it and weren't ready to release it yet. They said it"should" all be ready sometime in January. They also said they won't be selling the components a la carte anymore and will finally be offering a kit. However they will still acomadate those who may not need the full "kit" .

The only fjo items in my meth system will be the controller, solenoids, press sensor, and boost solenoid(when they get it sorted out)

So because I can't buy the controler for over a month, all I can really work on is the plumbing part of my setup. I received my first shipment of an fittings and lines but I haven't had the time t start putting it together. Hopefully I will have an update with pics by next weekend.

Great thread. I'm also planning on going with the FJO system soon...

Regarding the FJO boost control kit, why not ditch that and have the FJO Controller trigger a relay to shut down your existing boost control solenoid when the pressure sensor reports low pressure? No power to boost solenoid will drop boost to spring pressure... I'm guessing this is what FJO's boost controller will be doing (dropping the boost), but why buy something you already have?

You've got a good point, but I really like the idea of a boost controller that ties directly into the meth controller.And I also plan on using the FJO wideband O2 as well as there injector driver in the future and the fact that all the components are designed to work with each other is a big plus for me. .... And I already sold my profec

Can't complain with having all in one...Once I get some feedback from you on the FJO boost controller I might end up ditching my profec too.

the really neat aspect of the FJO boost controller is that it can run a 3 port solenoid. a 3 port puts PRESSURE against the wastegate to keep it from prematurely opening until target boost is reached. hopefully they will fix the bugs over the winter.
