How to Solve Your Subaru Fueling Problems. The Right Way!

I have those injectors in my subaru, worth every penny paid for them, along with new rails and fuel pulse dampers and rails from radium. The stock fuel pulse damper was not doing a good job, it was overwhelmed by the big 1300X series injectors, once the radium fuel pulse dampers were installed the tuner cleaned up my fuel map and the car idles even better and I think the mileage went up, my driving habits really haven't changed at all, so a combination of cleaner fuel mapping and pulse dampers really helped. I visit the gas station every 240 miles per tank instead of 190-200 miles per tank with the previous tune.

Sadly the Speed Density part of this video didn't age well with the Cobb Green speed update. Luckily with there's Haltech packages out there that use the old TGV plugs as inputs with Haltech's IO expansion module to make going speed density easy still, just a little more expensive. Great video's as always Mike!

ECUTek as well as open souce options as well.

I had a smile on my face throughout the whole video just like Mike. Really great instructor. Keep it coming, Mike..

Excellent information. The way you break it down for everyone to learn and understand plus a parts list makes your videos awesome for us little guys with tuner cars #Evo X

[@jessedickey8851]

I want this guy to do my next build. Keep up the great work. Always informative and interesting. 👍👍👍

[@rcstackz7333]

Great vide👍 Just ordered this hanger today!, will be running two 450s

[@timwilliams9865]

I appreciate the information I’m putting mine in a bug:) That sounds like an awesome fuel system

[@capnthepeafarmer]

It's great seeing Mike!

[@aersoul]

Iwire doesn't suggest 1 big fuel pump but instead 2 smaller fuel pumps to equal the desired flow rate. 1 big pump will start to fry the fuel pump controller due to the load going through the wiring. Smaller pumps will half the amp load while still having the fuel flow for desired goals. That's why the radium dual fuel pump hangar is a good solution for projects that range from mild to wild.

[@motoiq]

We were planning to go with the Iwire controller and wiring kit.

[@lucaswarren5947]

I switched to a solid state relay instead of the factory controller. Handles 40 amps.

[@subietechron7530]

I really like the attention to detail you put into building this motor. Hope to see a video of it completed. Yes Race teams have big budgets. Especially over in CA where I see you are located. I would like to know the MSRP for all the extra treatments and coatings. You do great work. I meant no disrespect. I think WPC treatment is the greatest thing since pasturized milk. Wish I had a racing team budget/write off. Good Day.

[@motoiq]

Most Subaru racers spend at least this and even more, this is an entry level high powered engine.

Can you do a deep dive into the cylinder 4 cooling mod, once and for all to set the record straight.! heard mixed reviews Australia wide.

[@TheMrFlyBoy18]

I have it installed and my engine feels normal. Reliability mod are a must in my opinion. Don’t forgot the iag oil pick up tube and baffle as well!

[@growingup4487]

I've searched through the all the forums and hour long videos from getadom, yes it does work.

[@dildodickings2668]

I heard it could mess with the knock detection system because the sensor is closest to cyl 4 and it should be the first to knock. I don't i just remember reading a lot of mixed things about it. To me it does sound a bit silly to create a system that relies on poor coolant flow.

[@evilclownatwork]

@@dildodickings2668 that might make sense actually, considering your ecu would make corrections based on knock.

[@dildodickings2668]

@@evilclownatwork But to desing a system where one cylinder heats up more seems weird. Maybe it just happened, they figured it's not a problem and put a knock sensor there. Don't know i have no clue honestly

[@paull9086]

The more I watch your videos the more I’m shocked Subaru is still in business

[@drewpickard554]

I always really like your videos. Now what I didnt see here, and it kinda gets a little bit confusing on the wild west of the google, is the Pressure Regular, lines, and dampener side of things. Its kinda all over the place if the reg should be before/after the rails, going deadhead parallel(Radium has a kit) and just things like that I would of liked to hear your opinions about it all

[@motoiq]

end of rail before regulator

[@mrmxpop]

[@Nanno964]

Love the videos

[@lucaswarren5947]

I've been looking at buying this for a long time but I've always been concerned that at higher G loads it will starve out. My Subaru is pretty highly modified towards autocross and time attack. Is there any bench test data for G load starvation at various flow rates?

[@motoiq]

Fuel starvation is pretty apparent. If the car staves due to slosh, it will bog.

[@bryanallendorf7064]

I'm glad they fixed this on the VB. But they added RTV to the oil pickup to decrease oil flow. Come on, Subaru, WTF!

[@ashleychandler4110]

Can u guys put in built motor on my 16 sti for daily drive and I take it to drag strip 2-4 times. Ever 1-3 years

[@bluegizmo1983]

$630 for that fuel pump hanger is insane.

[@TuneboyR]

MY tuner said (im running ecutek) that speed density is not as good as light loads. He suggested hybrid mode with Speed density above like 1,4bar boost and below to stay at MAF. I kinda want speed densitiy because of my athmostpheric Blow off and the engine is running crazy rich at those times. What do you guys with speed density are running? Speed Density all teh way? how is it compared to before on daily drive with light loads

[@motoiq]

Speed density all the way.

[@7urnme]

if i already had this hangar running and wanting to go further by adding a surge tank, would it make any difference?

[@motoiq]

It has a small surge tank, I would see if you get fuel starvation in cornering first before you add an external one.

[@7urnme]

@@motoiq thanks for that. also on the radium pump hanger, is it possible to replace the fitting on the manifold to AN fittings?

[@7urnme]

nevermind found it, it came with additional fittings

[@ivanperformance100]

What if I have that hanger installed with 2 walbro 450’s and I install a radium surge tank with 2 walbro 525 ?? Could be possible ?

[@motoiq]

Yes but you probably don't need that much lift pump.

What ever happened to the MotoIQ EP3???

[@motoiq]

It is still around and has nothing to do with Subaru fueling!

[@lukerogers78]

I bought that kit from Radian a few years ago. The fuel pump fell apart about a day after installing because the epoxy glue wasn't rated for gasoline. Radian customer service was nil. When I went to check it a week later. The all the wire insulation fell off because again it wasn't for use in gasoline. Radian customer service didn't help with that either. I was able to fix everything myself using marine epoxy and proper insulation but I was very disappointed in the products and Radian. I know a lot of people use their products and they work flawless but I for one will never buy another product from them.

[@motoiq]

Are you sure? 1. Radium doesn't make the fuel pump, 2. All of the Radium provided wiring and parts are either metal or rated for exotic fuels. 3. we have been using these in our cars and customer cars for years and have never had one single problem ever.

[@lukerogers78]

@@motoiq Radian doesn't make the fuel pump but they adapt it to work for the STi. Radian told me to contact Ti Automotive (brushless Veryon pump) but there was nothing wrong with the pump, it was were it adapts to the Subaru parts. I bought it all though Radian and sent them the pictures of everything when it fell apart. They told me how to fix it myself and never once apologized.

[@motoiq]

@@lukerogers78 of course they just sell the pump as a service. I don't understand what you mean by fell apart, all of the Radium provided wiring and materials are rated for exotic fuels and we have never had any problems with these in our cars or customer cars even ones that run ethanol all the time.

[@Chase_AM]

Radian’s not even the name of the company…?

[@analactica]

I wonder if they'd build an Impreza from the ground up , making anywhere above 600whp , fully built engine and rebuilt transmission , with an ecu , tune etc , and how much would that cost , I wouldn't trust anyone with such a project 🤷🏻‍♂️

[@motoiq]

We could and the cost would vary depending on what the end use would be, racing or street.
