port injection fuel options

[serialbooper]

so I'm looking to do port injection with my ams intake manifold. trying to see who else running an ams manifold, what setup did you go with? the visconti stage 1 fuel system I'm sure is the most popular, but im not crazy about drilling through my fuel hat and running a zip tie around my basket, but if it works I'm cool with that. obviously running the ams manifold i can do a feed and return line setup. i see the new options from radium and they seem perfect but requiring a fuel regulator setup and mounted somewhere I'm kind of in the dark as the lack of room due to the large intake. i came across Harrison motorsports in AZ that has done quite a few port injection setups with the ams manifold, but for some reason, its a secret and they don't want to sell it to me or tell me what the system consist of. not sure why everyone's setup these days is like a giant secret, people don't want to share info or specs. i am also aware of the titan system as well which looks nice. im really wanting to use radium products as i get a massive discount/free through my job who is a distributor of their products, but im open to what works best.

so basically any ams manifold guys mind sharing what port system they're using and if it works well with the visconti port injection harness/ motiv box?

or anyone running the radium fuel products (hat, plumbing kit, and fpr) did you run a second flex fuel sensor for the separate port system?

thanks for sharing

You don’t need to limit this to AMS intake people. It’s all the same, manifolds, plates, etc. I’m running viscontis fuel pump and kit, though I’ve heard great things about @Twisted Tuning’s fuel pump kit.

Harrison builds race cars, not sure why you’re shocked about them not spilling the beans.

Its not the same really, plumbing is going to be different due to placement (fuel rail is significantly higher than a plate kit) and size of fittings. most plate kits are feed only, im looking to run a return setup with a fpr, due to not wanting to drill through my fuel hat. Though your statement partially true across manifold setups, yes. Im looking for advice on running an isolated port fuel system, and what systems people with manifolds are running.

Because im trying to buy parts from them, why they operate a business!? Not sure how you’re confused. I could understand your statement if i was competing against them at a track sure but we are talking about street cars. was also more of a general statement with people these days acting like suspension setups and wheels spec’s etc, are some guarded secret. Was completely different in my younger days, always been happy to share my builds.

Yeah- I've just gone from a PI plate to the EOS manifold, the plumbing is exactly the same; I reused every component. It would be with Visconti's kit as well. If you're going with a return fuel setup, yeah, that's different, but the feed pump will be ~the same. Several folks are doing the return lines? I only know one guy for sure going with a return line on a manifold (Adam Lebowitz/ATR Performance out of AZ). Tapping the basket is really not a big deal. You can always order a second one if you're worried about damage. It seems you've modified enough to not really be worried about that.

You could also check with AMS themselves to see what fuel setup they're recommending for "extreme" HP applications. Norris at p2uned might be helpful as well, though I don't think any of their race program cars are running the return setup. They've all just capped the other end of the fuel rail.

I'll ask couple more of fast guys what their setup is like.

really? I thought the visconti fuel line to rail utilizes a 6an fitting vs most manifolds with rails have an 8an fitting, which is what started my rabbit hole into a fuel system that is more built for longevity.

only reason i want to run a return setup is to utilize the radium fuel hat, just something about using a zip tie to secure a fuel pump and drilling through my oem hat that will probably keep me up at night, plus i can get the radium stuff for free. I Like the idea of having a separate isolated system for port, but just curious what other fuel setups with manifolds are looking like. Appreciate your input

It's possible I grabbed a fitting or something out of the drawer of 'random fuel line shit.' I honestly don't remember. I can take a look tomorrow. I also asked Mike over at EOS if he's running a return-style setup. I'll report back when he text's me back. lol

thanks man I appreciate that. Yeah i know a return setup may sound stupid but if the radium hat has it already probably be dumb to just cap it off. Though now that i think about it I suppose i could just cap the ports and run a combo of visconti fuel system and radium hat eliminate the “drilling hat“ aspect of the visconti kit, that might suffice my OCD lol anyways appreciate the feedback.

Harrisons built my car with the AMS manifold and Visconti STAGE 1!! (@zrk) fuel upgrade and Motive P/I, but no return fuel line. Other than not wanting to drill into your oem fuel hat, are there benefits or requirements to needing a return line?

 

[serialbooper]

a fuel pressure regulator would be needed to run a return line. benefits would be to have the port system separate from the di system (and the better solution of the fuel hat, main reason for me), for most people its not important. it appeals to me because from my experience the way the visconti system installs doesn't scream longevity to me, seems like a temporary solution to a new platform, THIS IS MY OPINION. i don't claim to know everything, and proven wrong time to time. some of the top a90's don't run a return line, so food for thought. i am also very OCD about function, fit, and finish. its an issue.

also harrison has some very nice builds, dont think you could have chosen a better shop for your work.

Mike texted me back the other night, but I forgot to update. He (EOS Shop Car, neon green if you watched the TX2K vids) doesn't run a return line on his setups, though he doesn't run Visconti's stuff, it's custom.

I totally agree on the fit and finish portions. I'm the same way, I want all my lines and wires bundled up neatly, so there is something there. Visconti's system certainly isn't the perfect solution, but I think you'll be hard-pressed to find a solid reason to run the return style setup.

this is the battle I'm fighting in my head lol. 100% agree with you. ultimately i will probably go with the visconti system due to ease of installation until a full solution comes out with a dual flex sensor with plug and play harness for it. OR if i cant sleep at night lol i will do a full epic write up of the entire full radium setup catalog install. thanks for the info sir.

It was a good experience. I had a two choices for shops and choose @Harrison Performance. His willingness to make it easy for me was the selling point. Car was enclosed trailered from my driveway to his shop where it spent 7 days getting a majority of the stuff in my sig installed/dyno tuned and then delivered back with a complimentary detail. During the wait I rented his Lexus off Turo that he kindly left in place of my supra.

Ultimately i will probably go with the visconti system due to ease of installation until a full solution comes out with a dual flex sensor with plug and play harness for it.

I would say go with what works. Harrison may have done both setups but he will advise you to go with what works best based off their experiences.
