Twisted Tuning N54/N55 HPFP R&D.....

[TEC]

You mean like the multi-page thread where about 10 people have been posting up their experiences with it. Only one person said anything negative and it was because they misread the install document. After VTT pointed it out they had their Ah-Ha moment. The only negative trend is just the complexity of the install.

Or like the multi page thread over on bummerboost (which is a known VTT hater site) where they praised the Shotgun too?

There were some problems with the original mounting bracket, problems that VTT (supposedly) made right with warranty coverage. The new mounting bracket doesn't have those problems and the only reviews on the current version have been glowing.

There have been multi-page threads before on the shotgun and not one that I have seen have had dynos or logs. Maybe I missed them?

Even the bummerboost thread has dyno results showing DI only over 600hp on full e85. And if that sticky fingered butthole hasn't deleted that thread....when you know he hates VTT....

Couldnt find that thread but I did see one (the one that I remembered) of one person running the single shotgun and a bunch of people asking questions about it because no one had previously seen a review of one that was positive. I don't care for Tony either but if the product works, it works.

My question is, you don't think its strange that this product has been on the market for this long but you can't point to 10 positive reviews on it?

Every site seems to have masses of N54 discussions and members online compared to the later engine types and 3-series models and N54 seems to be the platform of choice by the tuning enthusiasts - by a very large margin. Providing solutions for the other markets first may just slightly balance the markets. Slightly, since every petrolhead went with N54 already. So I don't agree with the market priorization, however, I will buy your N54 HPFP upgrade when it is available.

I think this is the right thing for the community. The N54 already has the shotguns from VTT, the real need is the n55. Wise choice.

TTFS has a great solution for the N55, yours might be better but Im just trying to convince you back on the N54 so I can get rid of PI!

Honestly sounds like this was just another pipe dream from a group that had no idea the engineering involved in making something like this.

Based on prior feedback and experience on this platform, it sounds like the “change” from N54 was more so due to design challenges/reality setting in than market strategy. I’m not holding my breath on an N55 solution either.

Looks like VTT really has the market share in regards to running HPFP only on N54

Sounds like more N54 vaporware.

Everyone is entitled to their own opinion. But what i said holds true. The N55 needs this more than the N54. Post 2012 N55's can't even barely run E30 on their stock pumps on Stock turbo. Let alone make any power on an upgraded turbo without secondary fueling of some sort. So for me, a solution that will support the N55 and more than likely the S55 immediately makes more sense to release before the N54 where everyone has PI and will think 72 times about buying it because they already spent money on all the PI stuff. The N55 and S55 is the future of the BMW. the N54 will still be here.

There's no vaporware. I have no reason to lie about anything i'm doing or planning on doing. But, i have the ultimate choice of what direction i choose to go, and no one else's. I appreciate the concern and interest, but don't speculate what you don't know.

We all know DI is the best route. Which is why i made this thread to begin with. So just relax and try to be patient. but feel free not to hold your breath as well. The choice is yours.

No dyno results or log results yet but here is just what I pulled from 10min on the main page of this forum. If you do a search and go back there's tons more, and if you go to other forums there is even more. If you look at the time periods of the reviews you will see that there were some negative reviews 2-3y ago with fitment, and quality, mostly centered around the bracket cracking...but within the last 18mo to 2y you don't see those comments.

Done, it is definitely NOT a simple install. As Tony wrote in the installation instructions... Have A LOT of patience and TIME to do the install. Power steering lines/ connections to the rack took the longest to sort out. The mounting of the bracket and drive housing needs to be accompanied by a beer or six.

I like a vendor that straight up tells you their product install is daunting. No bullshit. Most appreciated!

Ive got my double barrel installed it was not fun at all. +999999 for patience

Bolt is in, used a washer and locking washer and it fit perfect.

My torque wrench didn’t fit in the space so I took ground down the end of my wrench to be able to slide on the end of the bolt and it worked perfect.

Just wrapped everything up, clocking the lower power steering bolt added the extra clearance I needed to clear the hpfp. I have the relocated inlets and reran the heater hose to better clear everything. I still have some things left to wrap up, but as far as the shotgun is concerned install was a success. My laptop doesn’t have a cd drive so I just used whatever driver it auto loaded and the R4 software was giving some weird error about wrong comport. If you’re in my same scenario go to https://ugreen.com/drivers/list-USB_To_RS232_Driver-en.html and get the appropriate driver and that fixed my communication issue.

I kept seeing the blower recall pictures all over my Facebook feed, so I decided to check and sure enough it was melting on me. I’ll be damned if I just did all this work just to watch it burn down, so I’m getting a rental from them. Check yours, make sure you’re good, be safe guys.

Now that makes sense with what you're saying about the coolant hose, I don't think me and Chris were on the same page or I wasn't understanding either way it worked. Would you happen to know the stock belt length? I see you had to use a longer belt for the triple pump did you get measurements of the stock belt before doing so.

hi
i have that double barrel installed and it fit all most like a glow to it`s place.
at first, i was sure than it cant fit on it`S place but there it is.
there was few minor issues with my kit, first one weld was to be little grinded before fitment,
but that is fixed on newer kits.
i did much better water line routing than it was on that kit and i had my engine hanging
on a crane without engine mounts cause i dropped subframe and rack away to install turbos at the same (GC`s)

on install, just follow the instruction and don`t force anything, everything will fit without force.

Tony was very helpful on every aspect on my build and don`t hesitate to ask if there is anything odd .

ps. on these very tight engine bays, you need for sure a bunch of different wrenches and tools because everything
is very tight fit so be patient on install.

like i told on my build, for sure i have much better infrastructure to do builds than average guy so there can be
some problems on lack of tools or resourses on your build but patience and time will cure everything..

Interested in the progress of the pumps and eagerly waiting for the launch of the N54 HPFP in the fall!

Q1 2018 looking at having something released or at a minimum on car being tested.

Q2 says hello

fail. there will be no N54 HPFP variant released ever. Only three possible means are DI (six more components that can fail, seven if you include the controller, not to mention the sandwich plate alignment using traditional bolts instead of the studs provided by BMR kit), the shotgun approach via TonyTurbo, or the very old school methanol injection via the chargepipe. No N54 HPFP development will ever exist due to the mechanism and structure of the N54 HPFP style. lateN55 models can retrofit to the S55 pumps.

in addition, the n54 community is rather dirt-cheap and nickels and dimes every vendor. from a pure financial standpoint, it's not worth pouring in 100k+ in R&D to make at best 10k in return.

 

[Ilkka]

Working out the N55 (Late E-series and F-series) solution right now first ahead of the N54 and Early E-series N55 models. The prior need fueling support more right now, and are the future of things moving forward anyway. Larger demand

Once i release that, i'll do the N54 and early E-series N55. So that solution will more than likely be pushed to Q3 2018. and the the Late E-series/F-series N55 will be moved up in priority to Q1/Q2 2018.

Some people may not like that update, but it is what it is.

So, it was Q1/Q2 and there is some of Q2 left and N54 would be "more than likely be pushed to Q3".

This differs from what Twistedtuning says.

Im hoping this makes it to market its an awesome idea and I really hope it comes through

I fitted a few double barrel kits on a number of cars and they are a bit of a pain in the arse to fit, they do work great and is the only safe solution at this time for the n54 platform

The first kit i fitted has been running over a year and done more than 10000km with no issues

I got to agree with twisted tuning that he focusses on the platform that has no solutuon at this time but it would be nice to see one pump do what an overdriven and a secondary pump has to do now but im highly skeptical it will

Only time will tell and badgering the guy wont get it done any faster

Bummer to see this switch over to N55. I hate VTT and refuse to run their products. I'll find a way to get some power without that shotgun. Hopefully, lol. I understand why you switched off to N55 though, so no hard feelings.

 

[DennisKing]

Resurrecting this thread to see if Twisted Tuning has had any luck.
I’m just wondering why people aren’t buying N54 vacuum pumps and HPFPs and mounting them to their N55’s? Is it a pressure sensor and DME concern because the space is there and plumbing is easy to work with.

my stuff for the N55 is just about done. took longer than expected. Troubles of being one person doing 100+ things. Then i can move onto finishing the N54 stuff.

N55 pumps are already being worked on being put on the N54 in another thread.

Long story short. N54 and N55 pump setups physically are interchangeable. N55 has a cam sensor for timing injection. Honestly, now with XDI pumps now available for for purchase. running the N55/S55 type setup on the N54 will flow more fuel. The hardest thing for N54/N55 interchangeability is Control. Albeit easier to put the N54 pump on the N55 since the control and functionality is there. But no point in that since XDI has released their N55 pumps.

see above

So the XDI setup is supposed to be retrofitted to the N54? Interesting.
If their pricing is in the range of what their other stuff is priced at though it will be a tough sell.

No, someone posted a thread on putting the S55 pumps on a N54.

If it works with the stock pumps then if someone really wanted to. They could install the XDI pumps instead of the stockers and in flow by 60-120%

 

[DennisKing]

S55 pumps are super costly. No thanks.

So is any solution that is going to increase DI flow in replacement of going PI.

 

[VACust]

If we’re lucky we’ll see high output HPFP in the $1600 range. LS engines HPFP that flow the volume we need are $1500-$1600 and there are a hell of a lot more of those out there being modified than the Bosch HPFP BMWs. There just won’t be enough demand for a manufacturer to be able to make the volume of product needed to have an $800 option for a long time.
