To piggyback off this question:

I plan on eventually getting a larger turbo as I already have all supporting mods. I have an xdi-35 at the moment but it sort of seems like I should go with a different hpfp. Will I make more power on stock turbo and a dorch hpfp or is the stock turbo/ xdi maxing out the stock turbo already? I'm on pump gas

So, you're not going to get much more out of the stock turbo on 93 regardless of which HPFP you go with.

But, if you change to the BM3 Stg 2+ E30 or Race Gas OTS maps and add the proper fuel, you'll definitely get a nice bump in power with the stock turbo: https://f87.bimmerpost.com/forums/sh....php?t=1782079

The XDI-35 should flow enough to max out the stock turbo with Race Gas. With ethanol, you'll be right on the edge in colder temps if you're running an E35-E40 mix and the Stg 2+ map.

My Dorch Stage 1 that flows a little more than the XDI will have HPFP drop outs in <45F weather with an E47 mix. If I drop to E40, it's fine. So, you may have to drop to E35 or so in cold weather, but that's still enough to make 440whp with the Stg 2+ maps.

I wanted to update the original post of this thread to include Nostrum performance, detroitm2 has informed me about this company and is working with them so he would have the best information for it.

So far their site: https://www.nostrumshop.com/product/vw-ea888-gen-3/ has the n55 tab directing to the VAG EA888 gen 3 hpfp upgrade, so I suspect the bmw specific data has yet to be published on their page.

Judging by the VW redirect it could be flowing 36% more than stock which if it holds true for bmws would make it equal to the XDI stage 1 upgrade for far less money, but falling way far behind spool and dorch. Warranty is also unknown at the time being, but hopefully it is lifetime like dorch and spool.

N55 pump is here:

https://www.nostrumshop.com/product/bmw-n55-hpfp-kit/

It's rated at 63% over stock. Though in talking with them, they mentioned they flow tested some other pumps on the market and are skeptical about some of the numbers posted.

I'm going to try to get some actual graphs from them.

That's better, ok that is really good numbers for the price. I will update the original post.

Also note: compatibility is only for N55's with the piston style pumps, so early E series n55's such as those listed in their vehicle application tab will not be compatible with this pump.


One last thing - Flow seems to be lower than other stage 2 pumps, but we will see when the data is released. If indeed this HPFP can match other stage 2 HPFP's in terms of max power supported on full e85 or pump gas then it comes down to 2 factors:

1) Price: If the nostrum pump can stay at the $1300 price and not jump up to $1650 price after it has launched for awhile then it will be the cheapest stage 2 HPFP out there which is a plus.
2) Warranty: Depending on warranty duration factor 1 may not mean anything. Because even if it is $400 cheaper (at $1300) than any other stage 2 HPFP, dorch and spool have life time warrantys which imo is worth more than $400. If the price is at $1650 after launch and it does not have a life time warranty then this is essentially not going to be a good option in terms of bang for the buck. Essentially what I'm trying to say is imo if an HPFP upgrade does not have life time warranty it is not worth it imo (unless it is significantly cheaper than the competition), especially when the competition is offering it.

Not sure I 100% agree on the warranty part.

There's plenty of aftermarket products that are highly recommended on this forum that carry little to no warranty. As you mentioned, we didn't have any HPFP options a few years ago, so manufacturers are just coming into this sector. I'm sure once we see them around for 5 or 10 years, and warranty concerns will be put to bed.

Additionally, warranty claims are always a crap shoot. If you do not fall within a very narrow set of circumstances, they're likely to deny you.

(not saying this is the case with dorch/spool, just in general)

I'll try to get some more clarification on the warranty this week and report back.

There were some rumors on the F30 forum that this pump didn’t require modified HPFP tables and would just plug in and have the ability flow more fuel without modifying/flashing your tune.

I thought that sounded a bit far fetched. Can you confirm if this is/isn’t the case?

I assume it’s not the case, but it would be a nice “feature” the have the ability to actually relock the DME on the stock tune while running the HPFP for trips to the dealer, even though most of us N55 owners are coming out of warranty soon.

They’d still see the pump and boost history and deny an engine claim, but just wondering.

Better question: When are you going to get to try a Stage 2+ map?

Indeed! I'm going to ask about that, and will certainly know first hand.

The stage 2+ tune being OTS isn't going to see a ton of benefit until they get their pump added to it. I'd imagine that the pump may work without tuning, but obviously a tune is going to unlock its full potential. I do plan in getting some before/after data logs and dyno charts to compare. I'm running the stage 2 93oct tune currently.

I'll know more in late January. Should be getting into the shop in a couple weeks.

So bit of clarification on the "run without a tune" rumor.

The pump will start without a tune. But it's not recommended that you drive the car around.

So it's not really viable to reflash stock tune before going to the dealership.

Couple updates here. These are directly from Nostrum.

Warranty:

"As far as the warranty goes, we have a standard 2-year warranty and as long as someone has proof of purchase, I'm always willing to work with someone if they have any issue with a product. The reason we do not offer lifetime warranty is because we build a quality product and we feel offering a lifetime warranty screams "our product breaks a lot""

Flow rate vs. competitors:

"So, we only offer one pump which is a Big bore and flows 63% over stock.

Spool and Dorch both offer a small bore and big bore HPFP. They claim the small bore is a 50% increase while the Big bore is an 80% increase. If I'm being completely honest, I do not believe its physically possible for the pump to be any bigger than the one we offer, and 63% is the maximum increase.

That being said I'm curious how they are making such a claim."

Pricing:

"Our price will most likely stay around the 1300-1400 range but I will know for sure in 2 weeks as we are restructuring our pricing in prep for 2021."


Additionally, I got some further information on bootmod3 integration. Not going to get anyones hopes up, but we may have this option available sooner rather than later. Once I get the OK I can give some more specific details.

Glad to see some updates:

1) I feel that life time warrantees show that the company is putting their money where their mouth is, and willing to stand behind their product not the other way around. Remember oem HPFP's on the F series fail when the seal breaks and the pump looses all pressure. This can happen to any pump and especially with higher mileage cars. Also personally I'd rather have a lifetime warranty than have a vendors word that they will work with me.

2) Can't comment on flow rates until we see the results and I am hoping these guys can compete with the other few companies.

3) If pricing stays around $1300-$1400 that will be excellent.


I will update the original post.

Yeah there are lots of products without life time warrantees, but when you are moving into a sector where the majority of vendors offer life time warrantees and the oem parts are known to fail at high mileage, then having a life time warranty is a huge benefit - especially when the prices are so close.

Yes these parts are generally very new, and when you are going to pick an untested part that costs alot of money, it is nice to know the vendor has your back with a life time warranty, and you are not gambling on the fact that it will be reliable. Every moving part will wear over time, so in those 5-10 years we will likely see failures not the other way around.

Warranty claims (life time or not) can be good or bad, but if the vendor wants to stay reputable then they will honor it. I would still rather have a life time warranty than not. Look at FCP euro for example, life time warranty on everything and anything they sell, not one case of not being able to claim it. This is the direct new companies are going to earn business, and it shows they can stand behind their product.

Btw this is from spool's website:

1) All products sold directly by Spool performance, LLC are eligible for the Spool Lifetime warranty program.

2) Warranty is valid only to the original direct purchaser.

3) Customers shall be responsible for associated shipping costs.

4) No fine print or blaming install errors! We just stand by our products!

Seems very clear and concise to me, like I said the industry seems to be moving this way where if you make a good product you can stand behind it. It also makes a consumer feel that the part is designed to last and not designed to have planned obsolescence.

Would there be any benefits from upgrading the fuel pump, if my only available gas is 93 octane pump gas and I do not plan to go bigger turbo?

Honestly, probably not. The oem fuel pump should be able to run 93 octane with a stage 2ish tune without much trouble.

+1


Zero gains to be had, it would be better to put your money into other mods.

[Oktom2]

Ok thanks! Thats one less thing to worry.

[detroitm2]

Tentative install date for my Nostrum HPFP is the week of 1/25. Hoping to have some data shortly after that.

I'm going to try to video the install process along with the dyno numbers before and after on various tunes.

Make sure the tune doesn't have the low rpm high load (full throttle) tip in hesitations. The bm3 hpfp tick box for the xdi pumps seem to have this issue, but I believe they can fix this with more refinement.

[-Eidos]

I'm currently working with BendCalibration and a vendor on testing a stage 3 HPFP solution. It's projected to flow over 120% compared to stock and is a much tidier and less complex solution than the S55 dual pump retrofit that's available on the market currently.

Very nice!

Keep us updated when the vendor is willing to give more info so I can update the thread.

Looking forward to this. I don't personally want to run wmi or PI so this will be my go to.
