Don't get me wrong, that is a great amount of power and would fit your car brilliantly with it being a daily driver. Also the other upgrades all around would keep things nice and balanced at that point, but on the other hand I couldn't imagine investing all the money are the manifold, Port Injection controller/fueling, Stage 3 LPFP, and many other things for just around that power level.

Turn it up to 25-26PSI and milk out about 650WHP or so from that set up!! Im sure everything would be perfectly happy to do so

I know we all have different goals, but for 20-23 PSI on an E85 blend with a 6062, I would probably have done a single shotgun or a slightly bigger turbo to possibly make that power on just LPFP upgrade and stock DI

When I get PI and my VIE kit dialed in, I plan to push 26-27PSI on the 66mm Garrett on full E85, looking for 680-700WHP, so I decided the PI investment will be worth my while. Although I was considering a more simple set up with a single shotgun + E85 blend before that, the deciding factor against the shotgun was that my WHP goals are just slightly more than I think it is capable of, otherwise I think in a lower HP application its a great route to take
Yes, been very excited to get my fueling pieces in order. It's really the last thing standing between this car and making serious daily drivable power. In all honesty, I'd be completely content with 560-600WHP on E50. That's always been the end goal of this build. I'm all for pushing limits, but as I've always touched on, I'd rather have longevity while I still use the car everyday. But you're also right, I'll have the ability to turn it up to higher boost if I want, maybe for a dyno day or something special. I feel like if I've built the car for 700WHP and running it at 575WHP, I may save myself some headache while still having a brutally fast daily.

I considered the single shotgun, but the reviews I read were not very flattering. Most people had to modify their kits, had pieces fail, etc. I know they've revised them recently, and it seems a lot of people are opting to go the double route, but I also don't want to be swapping out HPFPs all the time. And I like the idea of PI if controlled correctly. A bigger turbo would have flowed even more air, requiring more fuel, at the same boost, so not sure that would have helped me hit the numbers with no extra fueling either. Especially with a weak HPFP, which is what I think is happening.

What PI setup are you coupling with your new single setup?

It's now been 10,000 miles since switching to a single turbo setup, and I'm still daily driving without any issues. Temperatures have been in the high 90's more often than not lately and the 1er handles it with ease. For the past 5,000 or so miles I've been running 17psi on E20 fueling -- with great looking logs. No timing drops in any cylinders, no fuel pump drops (high or low pressure), and boost comes on hard and stays rock solid right at 17psi. Any more boost or any more ethanol, and my HPFP can't keep up. Everything else is holding up well and the Blackstone Laboratories reports keep coming back with good news.



With 110,000 miles on the odometer now, I've finally acquired all the parts to address my struggling fuel system. While my old parts worked brilliantly with a lot of ethanol on stock turbos, they simply couldn't keep up with all the newfound airflow. The new setup will consist of a Stage 3 bucketed LPFP (two 450s, the second on a 15psi Hobb's Switch) from Fuel-It! in the tank, flowing through upgraded Fuel-It! fuel lines into an ethanol sensor which is integrated into the JB4 Mobile App, into the camlock fitting y-line from Fuel-It! - one end flowing into the Phoenix Port Injection manifold with JB4 PI controller, and the other end flowing into the HPFP, which will be brand new.

Once I have all that up and running, I'll probably link up with a professional tuner to dial in something around 23psi on E40-E60 for every day purposes and continue to DD and maintain everything until the wheels fall off. Until I can install all this hardware and iron out all the kinks over the next month or so, here's some more photos:

Before I installed any of the fueling mods I'd acquired, I first needed to pass inspection in North Carolina. I passed last year as a FBO twin turbo car running catless downpipes and resonators in place of my secondary cats by flashing to MHD stock map 0, turning the JB4 to map 0, and getting inspected in the small window in between achieving readiness and throwing a code for not having cats installed.

In 2018 however, I had transitioned to a single turbo setup and still had no cats. For weeks I struggled to get readiness. I flashed the MHD stock 0 map (not enjoyable on a single turbo car), turned the JB4 to map 0, disabled auto clear mode, and monitored readiness with the MHD app. For weeks I couldn't achieve any type of readiness no matter which map I was running. Through research, mostly reading v8bait's posts, and watching Budget Bimmer's video on the topic, I discovered that as long as your state allows 1 not ready, like North Carolina, that passing inspection should not be a problem. More than 1 not ready, or an illuminated check engine light on the dash, and it's a fail.

Using TunerPro software + the Budget Bimmers video as instructions, I activated EVAP and deactivated the secondary cat codes within the BMS BEF I was using, made sure not to touch anything else, saved the tune, and flashed it to the car. This theoretically would allow me to keep the car in map 2 at 17psi on my preferred BMS pump gas single turbo THR tune, and still be able to pass smog testing. Unfortunately I was still having issues achieving any type of readiness across the board.

Just as I was really starting to get frustrated, I remembered I had unplugged the rear o2 sensor connections within the JB4 harness when I was working out o2 sensor gremlins months back. I went back inside the ECU box, reconnected these. I had essentially already coded them out using TunerPro, so they wouldn't cause a CEL, but now they could achieve readiness. Sure enough, a few drive cycles, and we were showing readiness everywhere except catalyst. Knowing I could still pass with that one not ready, as long as it wasn't a fail, I headed to the small gas station down the street that I've been going to for the past few years, and it was quickly pulled into one of the bays for inspection.



10 minutes later and I was ready to go until summer 2019 with passing colors. It's nice to know that I won't have any problems in the future running single turbo, with 0 cats installed, and running a JB4 + BMS BEF combo.



Fueling mods and more boost are scheduled for early August, but until then, I'll continue to beat on her daily.

Seems a lot of trouble, but congrats on the Cert!
I don't think "Cat's not ready" would fly too far out here in CA...

IIRC, in certain states such as California, "catalyst" can not be the one monitor showing not ready.
