My Port Injection Set Up

[SilverDemon]

I can do some tuning, but I am not too proficient at it.

[agentgordon27]

so I wonder if looking at the toyota PI/DI system in the BRZ/FR-S would be of any use... at all. I know the port injectors flow around 200cc, meaning they are probably used as valve cleaners more than anything.

Mark, don't even waste your time trying to match his OCD bay...you will only depress yourself into a drunken stupor.

Scott...you are still my hero in how you implement your ideas...they are not only functional [i.e. get the job done] but they are beautiful to look at which is what I strive to do with any mod I attempt.

keep up the good work and bravo! for this PI setup man!

i think he had to put off buying his FPR because he needed new tennis balls on the walker as well =(

Give em hell SilverDemon!

Get them damn kids off ya lawn!

[SilverDemon]

Alright...so I did do some work on the car this past week end. Not much though, mounted the controller, and routed and connected the wires. I am up to the fuel pump and regulator install, not sure which route I am going, but I have to make up my mind before the weather changes since I do not want to be stuck in the garage working on this while the weather is nice..

[kmac]

I'm very impressed, it looks beautiful. Goid luck brother. Hows it working out?

[SilverDemon]

Thanks!

I still need a regulator and fuel cell w/pump and all the lines. So I have not drove the car since I started on this. I am shooing for a month from now to have everything up and running.

[RE-ACTIONENGSPEED3]

Can`t wait to see the results of it....

[SilverDemon]

It has been a while since the last update. I have completed the install, and have driven about 100 miles and went wide open about 6 times with this. For a base line rich map in the AIC, this is one nice set up. I should have done this before ever installing the meth injection. Although water/meth has its place in a turbo application, this is a far superior fuel delivery system.

I installed the FPR behind the small battery box I fabbed a while back, the bracket it is bolted to is actually the stock mount for the OEM battery box. I only have a mechanical gauge to set base pressure right now, my next step is to install an actual in cabin pressure gauge so I can keep tabs on the fueling. I have a boost pressure switch installed on the pre-I/C side of the piping to pull in the fuel pump relay. I put it pre I/C because that pipe will see the boost before the intake manifold will, in turn activating the pump with enough time to pressurize the system. I also installed an LED in the dash on the output side of the relay just to let me keep tabs on the pump circuit. The boost switch is made by Design Flex, it is a very robust high quality switch with a 10 million cycle life, and it can be end user adjustable. It has a burst pressure of 300psi and can be set to engage from 1 - 25psi.



Fabbing up the bracket for the cell. I used the mount for the spare tire and built a battery box type clamping device to hold the cell in place. I used all 1/8" angle and lined it with a rubber gasket to keep everything isolated from vibrations.





Built a false floor and a simple wooden box around the exposed fuel cell. Not sure if I like this, I might end up forming up some aluminum sheet metal and then covering it with carpet, but it will do for now







Dropped the lines to bulk head fittings through the trunk floor, added a fuel filter. By using the bulk head fittings it keeps the lines tucked up close to the under body.



The filter breather on the vent line.




One thing I found out the hard way is the lines that run inside the hatch area has to be ran with Teflon core hose. I ran them first with standard Aeromotive -6, this will permeate the fumes from the fuel, not good when the car sits for a few hours. I have since swapped out the lines with the correct ones after these pics were taken.


For tuning right now, I pulled 3° of timing out of the ignition tables until I get the AFR's ironed out with the PI. I am also running pump gas in the cell right now until I make sure everything is right with the system. I am going to the speed shop this week to pick up some 112 octane and I will slowly bring the tuning back up to where it was with the 1100cc's of meth...LOL!!

[Dano]

doin chit right!

kids... pay attention to the detail in Scott's installs and try to keep up.

[ABolewski]

How come I feel like I'm "breaking ground" when I "design" my Blow-Thru MAF when shit like this is going down on MSF? Lol
Looks sick man!

[Downmented]

Looks clean as fuck. I actually just finished with the dual in tank pumps and wiring/ hose ran up front. I really wanted to put the fpr under the hood but running 2 separate hoses from the itfp to under the hood.

Scott it looks amazing. Thanks for giving me some great ideas on how to finish off my tank mount!

[BlueStreak]

Everything looks OEM. It's ridiculous.

I love it.

Looks awesome.

Why 112 instead of E85?

Too far away, the closest station is about 45 mins in the opposite direction of anywhere I drive. But, 112 I can get on the way home from work.

Trust me, I would love to run E instead of the costly race gas...it's just not feasible.

[Dano]

Are you not concerned with the breather filter getting wet and grimy where its mounted?

I suppose its probably the only location close enough to provide proper venting.

I could just imagine you running a vent tube up through the C pillar and have a snorkel under your wing or have it vent behind the OEM gas tank filler door

Yes, I actually am concerned about the filter getting nasty very quickly. It was the closest, and easiest place to mount one.

The OEM filler door option is something to think about, I like that idea.

I had thought about adding a charcoal canister and plumbing that back through the stock purge valve, but I do not know for sure what that would do to the tuning side of things.

These are some of the things I will improve on later this summer, and I am sure there will be other ideas pop up as I run the system longer.

[Dano]

SD Fuel Cell 2.0 lol

good chit Scott. I think the fuel door is the best option if there is enough room in there and fairly easy to implement.

maybe a longer skinner filter that would mount over the top of the filler neck.

[Celestspeed3]

What about running the vent to the stock EVAP system. This way when the car is off and sitting your fuel is not evaporating in to thin air and wasting money. The vacuum from the stock system will also help keep the water vapour out of the system.

Yes, that is a great idea! Nothing like having $10 a gallon fuel just evaporate into thin air. I have some other things I have to do first, but once those are cleared up I will put the car on the lift and see what I can do.

[breakfstincluded]

you're my hero

[4DRHTRD]

Awesome to see this, I'm stealing ideas from yours for my PI install on the Flex
One thing to consider, you can buy 55 gallon drums of E85 and store at your house with a cheap pump. If you delta the price between 112 and E85 it would be worth the inital expense over the long haul.
Locally 112 is $10+ a gallon, E85 is $3.50 wholesale. $192 for a 55 gallon fuel drum of E85 vs $550+ for the 112 taken little bits at a time.

Another option, make your own E85 in your back yard!

Build a 3-inch ethanol fuel still

Not as clean as the OP (btw, very nice job IMO) but its what he brought me to work with and how he wanted it.

We are running 4 Fuel Injector Clinic 1100cc Injectors and I modded the in tank basket to run a double pumper setup. 2 DW 65c. They are both running full time, direct wired. We ran the OEM feed line, Tee-d in the engine bay to the port system (Distribution rail hidden under rad core support) then returned back into the into the tank from the FPR. So you have same base pressure for your port and your DI. Last I head from him a few weeks ago, he was at 36-37psi on T3 HTA 3582. He runs 50/50 Emix and has the DI and Port running at ~75% IDC right now.

[ms3blackmica]

I love you Scott

[psychophyr]

How much time on average to you spend cleaning that engine bay?! Looks like you could eat off it. The attention to detail SD puts into his work is unbeatable! Can't wait to see more progress on this.

[Dano]

Don't think the car gets driven



Tappin

[Realgib3]

Only gets driven when the old man gets out of his rocking chair, which isn't often at all.

[stlskater92]

This is epic shit!!!! Gonna have to keep my eyes here for future awesomeness!!!!

Thanks man!!

I do not drive in the rain or snow, this is not my DD, so other than a few bugs, it rarely gets dirty. Trust me, I drive the hell out the car in the warm months.

The progress is about as far as it is going on this. Other than a filter breather for the standalone fuel cell relocate, I am probably at the end of modifying. From here on out I will concentrate on tuning and see how far this fueling lasts.

LOL!! I will have you know that I drove to the east coast nator meet in 7.5 hours of rain!!! I then spent about $6 and 3 hours at the car wash when I arrived.

[Dano]

That drive had to be painful for you. Hahah

Making the ethanol isn't the hard part, but because ethanol absorbs water it will have some in it straight out of the still. You could probably still use it but if you want the pure stuff you need a molecular sieve. My chemistry teacher told me about it, and its just rocks that absorbs water and then I think you just put them in the oven to dry them out again. I was going to make ethanol last summer and never got to it. Maybe this summer because like SD I have no stations convenient for me.

My biggest regret was not chatting with you and your intelligent mind more at the track.

Next time!

[Celestspeed3]

Hey Scott, have you changed your vent setup around? I was thinking that a check valve in the vent line would allow the tank to relieve vacuum and stop the fuel from evaporating out.

[SilverDemon]

No, I have not changed anything yet. I am working on the joint shaft support bearing issue right now.
