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

Such an underrated channel. Been loving the vids!

You do such a great job explaining everything, keep up the good work!

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!

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 :)

This guys’s going to make me go broke with all these goodies😬. Love the channel bro, I appreciate your content.

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

How has this been, 3 years later? Looks like they create alot of noise and vibration and I wonder how the hpfp held up overspeeding?

thanks for the info. You have such a soothing voice, can i get a recording of you singing hush little baby, so I can play it to my son when he's crying? lol just kidding.

Your videos are totally useful! If that work okay, that will be the easiest way to upgrade your fuel system to 700hp. I can't wait your next video!!! Greetings from Bulgaria :)

I think you may be the first on You tube with this pump. Hope it proves out.

Favorite n54 DIY channel hands down. Surprised theres not more subscribers.

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

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.

Nice vid. Got a Helix OD on my early e series n55! Loving it man, definitely a better option than PI imo.

Wow. That's great news!

I love how he re-explain on all the how To's even though he has a video of each different install

I'm surprised no other company like fuel it, vtt, precision raceworks/ bmp thought about this type of mod to the HPFP earlier but nevertheless I'm happy to see something so simple release I JUST HOPE IT'S RELIABLE AND KEEPS THE HPFP RELIABLE as well

Spool hpfp upgrade update 2021?

Nice! way easier install than the alternate belt overdrive offering. Thanks for always sharing helpful info man! Best of luck on dyno day.

Can you please provide update videos for this and your new turbos regarding reliability? I want to install this along with Dynamic Autowerx's turbos, but I'm not sure if these will be reliable over time due to controversy over these products on e90post. Thanks!

Does it increase the likelyhood of failure by 4 or are the replacement HPFP's just better?

Who down votes these videos? I mean come on, really?

Love these videos ❤️ ... Sooo informative ... " The More You Know " ...

so sick man i cant wait to hopefully grab one of these for my e92 build! Your channel has helped me a lot, thanks man

Awesome video. First time ive seen this part by a different brand and a nice kit with fikter as well. What WHP do you think is available running full E85, with the 4xhfpf OD kit? Stage 1-2 stock frame TT's?

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.

Just discovered this channel! thank you will keep following your DIY vids - thinking about getting this here Im currently in 135i 465whp and ran out of fuel going doc race soon

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.

Been waiting on some more info on this Overdrive! Thanks man

Do you have any results before and after helix installed? Power and pressures? I am thinking about order, just would be nice to know, how it all goes. Or is there any video with it? I cant find anything. Thanks Matthew Czech republic

Without doubt the best diy n54 videos on RU-vid! very informative, easy to follow & descript! Well done I'm a recent but now loyal fan from Brisbane Australia...

I’m stuck In my build I need injectors is there any other way I can get around it or cleaning or know anyone else who manufactures them or do I really need to spend 1300+?

8 month update review. How has your Helix been holding up? any issues? have you ran full e85 or just mixtures?

Took me an hour to install thanks to your video. Thank you sir!

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. Designed for the BMW quick-connect standard charge pipe, but I just cut the input pipes down a bit and glued/clamped the silicone pipes from my alloy charge pipe to the bottom of the valves. (Not a shill-link - I just think they're very good)

I need a tuner too tune min 2007 335XI I have the spool HPFP over drive and can’t find a tuner too tune me on a awd Dino also but I. Keep misfiring on Cylinder 6 but cars still runs lmk get back ?

any problems with this so far?

Any discount on this product it’s $998.99 lol I want it but fuck

N54POWER😁👌

What actually goes wrong with the original pump? A washer? A seal? Shaft play? Bearings?

Hey man, a great new idea, I didn't know something like that existed until now, did you consider meth injection for more fueling? It also has advantages of cooling and cleaning the intake valves, but I don't know how much more hp will it give you with the upgraded turbos I installed similar turbos to yours but still MHD stage 2+ and I am not sure the next step for me.. bec6i know to get the most of it I should upgrade the fuel system or go Methanol injection or port injection..

I dont think that the hpfp is designed to go faster then it was designed to . but we will see .

So, 1 year later, and these overdrive pumps fail pretty frequently and have washed cylinders, and melted pistons lmao. Dec 2020

BMW = half of the engine components fixed with zip tie :-) :-) :-) during of "high" quality plastic

I'm trying install the billet plate. Did you remove the vacuum housing plate and use the billet in its place. It looks like the vacuum plate is still on in your video.

Ahould of done port injection. You would of eliminated the carbon build up on your valves

Nice I just installed mine. I got the 3x. Any problems so far? Do you have the little "Blender" noise issue with yours?

U r so fuckin bad ass . Nice work man ! Dang

Is the helix still installed and well? I keep hearing horror stories on the helix! I already installed mine and I’m nervous

Are we attaching the old high pressure fuel pump to this upgraded one or was that just a back piece?

Any further instructions available for the 10 micron inline filter? About to install this but can’t determine if the car needs to be lifted in order for the spool inline filter to be fitted properly with the helix.

Aren't you supposed to replace the gaskets every time you take the intake manifold off? I'd plan on doing that while I was in there if I was doing this mod.

“K so that clip went flying and I don’t feel like finding it rn” me 💀🤣

Between this dude and m539_restorations I’m getting my bmw fix

Great vid, love watching any good quality car work

Where to find this part? Can’t see on official web page spool. Can you give direct link on the part ?

Does those part will increase the reliability of the HPFP? even with stock power

As always great content, really looking forward to the test with the new tune

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?

Will this work on an automatic 335i xdrive.?

Is it true, you may have to lubricate planetary gears? I thought the unit was maintenance free.

I appreciate this video. I'm installing the Helix in my driveway but will need to take the low pressure line to a shop that has the vise. Would you estimate a 30° bend out and down or less? Also, does the manifold gasket need to be replaced?

Does anyone know if A single Walboro 525 alongside a helix overdrive would give me enough fuel for 600 hp on 19t turbos? Or do I need a bigger lpfp

Your vacuum plate holding up? I noticed your install was prior to the Billet 6061 plate being included with the Helix OD. I'm seeing a supporting block mount is in development as well. Also curious why you didn't go for an inline Fuelabs filter rather than their in-HPFP solution.

Off topic, where is the oem fuel filter located and is it replaceable? Is it a Maintenance item?

What makes this different than VTT's Shotgun or dbl barrel kit? Which Port Injection has been proven to be better then.

Sir how much power will you make with the turbos? Ill be buying them soon as well in couple months and this hpfo as soon as its out. How much does this hpfp would run about?

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.

Did this kit effective and has there been any issues with it to date?

have you had any problems with the inlet metering valve actuation?

Did you ever post the dyno video and results on direct injection?

Any update for this? Trying to decide between the 3x and 4x!

Any updates you are able to share? How many miles have you put on the OD unit? Any issues tuning or with the actual HPFP itself? In the market for one of these. Time will tell!

Looking forward to the next video!

What filter did you install? And also did the low pressure hard love come with your kit?

It may speed it up, raising pressure, but won't you run into problems with volume?

Hopefully something comes out for 2013+ N55s that doesn’t cost an arm and a leg.

Love your video man if I live near you I’ll pay for you work on my e92👍

Okay I went to spoolstreet to purchase this and can’t find it. Is this not available yet ?

Can’t wait to get mine on the exit list

Will work on E series N55's before 03/12 as well.

Hi, how has this HPFP worked out for you?

I need it I need it

how's it after 4 years? 🎈🎈

Oh man I'll be a beta tester! In fact I'll be the master beta tester! 😉 nah, excited to see the results though.

I added a helix to my car today and seems to have a rattle that gets quieter when the idle comes down but loud on start up ..do you have this issue too ?

The best

Was about to hit subscribe but i already was :lol:

Which one u recommend Helix overdrive or PI?

Awesome video, very detailed. I just ordered this kit yesterday so hopefully I’ll be getting it soon. I’m curious about where you mounted the new larger filter though. Is it under the car behind that plastic cover you unbolted? And is a new fuel line necessary since the filter is being added? If so did it come with the kit? Thanks!

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! ;)

Lmao my bolts were stripped on the hpfp when I did this 😂

2023 UPDATE?

Which tuner did you use for your setup? Currently upgrading my twins as well. And possibly running the motive flex fuel option with mhd.

finally!!!!!!!!!!!!!!!!!!!!

i just bought an hpfp shitty one 😑

Hi mate, i have a question. You need update the pump inside in the back seat before install this one? Thanks.

How’s your hpfp holding up since the install? Also did you ever dyno or retune for the helix OD? Can you share some updates regarding that? Much appreciated and respect ✊

I hope this will work with AWD models since the double barrel shotgun mod doesn't work with XI/xDrive.

Sweet!
