Is This The End For Port Injection? | BMW N54 HPFP Overdrive Kit!

dude this channel is gold... any work that cross my mind to do with my car is documented here...!!! thanks for that!!!

[@von...]

the line you bend around 14:28 and that stock HPFP -> fuel rail line have similar issues as a result of the manufacturing process/limitations. That why the twisted tuning guys released the high pressure "rubber" (or whatever material it actually is) line to replace it that bends while closer maintaining the same ID (internal diameter) as if it was straight compared to the hard metal lines that definitely suffer losses to the ID in bends. Getting a full replacement kit made for the line you had to bend yourself would be a smart move for Spool Performence to get dialed before the consumer release. I am super hyped on this product, as someone with an XI N54 this is really a game changer since I have been avoiding PI for a while now, but now I am hopeful that I can finally run full E85 with my Pure stage 2+ hi-flows DI only!

[@all4bspinnin311]

Another great advantage is that this can be used on the 535i and 335i x drive which traditionally could not use the VTT shotgun pump due to the size of the power steering pump. Also, since the E series N55 shares the same pump as the n54, we can use the overdrive on those cars as well :)

Thanks for your clear no-nonsense procedure. I just started replacement of my starter motor on my 335i and found your details to remove similar parts very helpful. Your method and comments to clean the carbon from the intake valves appears better than my spray and scrap approach. I used a wet/ dry vac to remove cleaner and carbon pieces.

[@o0cscore0o]

I’ve been waiting for this to come out. I’d rather not run PI and just stick with DI. Trying to keep it simple and less points of failure. Recently converted over to Speedtech bottom mount with a PTE 6266 Gen 2 BB on an e30 tune. I’d rather go straight e85 and not mix. Can’t wait for the results and when it’s released.

[@SupraSav]

Ah, the things we do for big street power. It's been fun owning an N54 for the past 5 years, expensive, but fun. I probably wouldn't change much if I did it all again, but damn I am glad to be selling and going to something more handling oriented and less than half the power - and half the maintenance with prices that are half the part cost.

[@ForzaPulls]

🤔…..The n54 is beyond cheap to maintain if you wrench 🔧 lol

[@Pe3Cee]

I love how your engine is super clean! I noticed you don’t have an oil catch can and yet your TB looks amazingly clean, not one drop of oil...

[@VehicularDIY]

Thanks! Yeah this engine surprises me, I can go 7K miles between oil changes and I don't need to add a drop of oil. Considering it's got 192K miles that's impressive, also when I had the turbo's off the exhaust ports were dry and it looks like it's not burning any oil at all.

[@Pe3Cee]

Vehicular DIY that’s amazing! Wish I can say the same thing about mine. Recently replaced valve cover with new gasket and bolts following your guide as I had a leak from there for a while, (carried out the job 3 times - 3rd time is when I bought brand new cover with bolts - as after running the car a little while, smoke from manifold and a small pool of oil accumulating on the oil tray that runs along the head). No more smoking now and less oil smell, still getting a small amount of oil accumulating on that tray where the boost solenoids are, I’m just hoping it’s residue, otherwise I don’t know what it can be. I physically can’t see oil coming from between the gasket right above where the oil is accumulating so no idea and I was super careful making sure it sat flat and torqued down with correct pattern. Anyways, I enjoy your videos, keeps me motivated to keep attacking maintenance on this car, I’ve been a long subscriber!

Wow. That's great news!

[@alexandermuellerpersonalac9769]

I truly appreciate that you took the time to make this video! However what I cannot figure out is what filter am I deleting to add the 10 Micron unit? Yes I have the engine end of the 10 Micron unit coupled on to the metal line under the starter, and I've traced the OEM black braided fuel line down to a mounting plate down near the footwell. Once I figure out how to unplug this original line and plug the white clipped end of the filter line in there, it also leaves questions of how to cleanly install the filter unit. Are people generally leaving it in the engine bay or trying to tuck it beneath?

[@mashinajoe]

I use VTT Double Barrel Shotgun. Full E85. Never liked port injection. 2 different fuel systems is too complicated.

[@kylerwinters]

Also alot more failure points. When port injection systems fail, they fail bad.

[@abonares]

[@dustinbyrd832]

[@Breadmaker42]

[@quik5ltr]

Excellent work as always, best N54 content around. Does this need specific tuning to take advantage of the extra fuel flow?

[@VehicularDIY]

Thanks, yes typically you would only need this with upgraded turbos so you'd be working with a tuner anyway. If you installed it on a stock turbo car in preparation for turbo upgrade you could without needing a tune as the car would just bleed off the excess pressure but then you're putting more load on the HPFP for no real gains so I'd recommend people have it ready to install at the same time as the turbo upgrade and to clean their intake valves while they're in there.

[@misterp4047]

Ok VD so tuning is needed when installing the Helix overdrive because i have the same upgrade turbo's like you from Dynamics Autowerks. My tuner is going to be WedgePerformanc

[@fujifast]

Hi! Just want to ask how your spool overdrive is holding up? Been using mine also for 2+ years. 1 thing I don't like about it is the loud chatter.

[@juancarlosathome101]

Ok ok ok... okokokokok.... I'M FREAKING OUT HERE!!! :))))))) For real for REAL!! Are you 100% SURE in EVERY POSSIBLE WAY that this will work for an N55 Engine??? I've seen a couple of mentions in the comments affirming this... I have an N55 (bow down to the N54 in terms of power possible for sure, but I'll take reliability over power any day! ;) -- if this kit will work, I would love to be able to use it! Circumventing a port set up seems SO much easier for the option to go E85! My goal is 500 WHP because I still have a stock clutch with my manual tranny. To that end, would you happen to know what the WHP limit would be on a stock manual clutch? I know that the price-per-horsepower increases exponentially as you go up the curve, and I would really not have to be forced to replace the clutch yet with a higher performance version--hell of a job and lots of $$ on parts! My car only has 57k miles on it, so the stock clutch should still have quite a bit of life left. But I was just curious about this in case you had come across the figures--I'd love to take the clutch to its max power-wise! :) Anywho, my stock HPFP is just now starting to go on the fritz--this would be a PERFECT upgrade, and I cannot imagine that the cost would be anywhere near going port, with the need for a whole new manifold, extra injectors, extra tuning/modules, etc. and the added risk of the port tuning being off just enough to blow the engine!! I have several questions: --Will standard injectors work? Any recommendations as to which to get/from whom? --How would this HPFP system work with tuning the AFR on the car? I know you mentioned direct control from the ECU and a couple of valve setting tweaks and pulling out that stock filter in the HPFP to increase flow, but really? Is that it? Would it be that simple--nothing else needed? XD XD --Pros & cons of 1-to-3 vs. 1-to-4 rotation options other than E50 vs. E85 and power gains respectively (if any) --The in-line filter supplied by Spool: is it replaceable/a maintenance item, and as such, can it be mounted under the car in such a way that it remains easily accessible to allow for easier replacement? --I have a FuelIT LPFP upgrade, will this be compatible with it? --And the last is longevity of the HPFP under these new parameters, but I suppose time will tell on that one... I am currently in the process of replacing as many components as possible through FCP to get the lifetime warranty!! This is literally the same as replacing the HPFP alone--pretty much no extra labor, which is just so great! And as a closer, your content is GREAT!! Dude--so informative and the fact that you're taking the risk on these new types of items as a guinea pig is really inspired, helps out the culture SO much! Thanks for what you do and keep it UPPP! ;)

Just for future reference, I installed this plumb-back kit from Australian manufacturer TurboSmart www.turbosmartdirect.com/Product-Categories/BMW-Kompact-BOVs/Kompact-Plumb-Back-KIT-BMW.html By far the neatest bolt-on kit on the market - proper formed plumb-back pipes and really good quality units.

[@VehicularDIY]

I've put about 2K miles on it, the tuner did play with the volume control valve tuning to open it up a bit more, pressures were dropping in 4th on the dyno. The HPFP is still working fine, the OD unit works fine also. You get a bit of chatter on first start up until the motor settles down but it goes away after a minute or so. So far so good.

[@VehicularDIY]

Ease of installation primarily, only if your power goal is north of 700 WHP would I say that port injection would be better but really it's your only choice at that point and you're near the limit of the bottom end. I get your viewpoint but I guess this would be targeted at more of an average consumer that want's less than 600 WHP with upgraded twins vs a single turbo upgrade pushing 750 whp. For the people that want 550 WHP with automatics and upgraded twins this would be easier and safer if they're not looking to break records.
