Hi all - I wanted to make a thread to share my feedback, results and experience with the new TTFS XDI HPFP upgrade option we have now available on the market. The HPFP is mated to a PS2 Turbo and being tuned via BootMod3. I am doing my own independent testing on this setup and I'm honored to be supported by and working with some of the best names in the game



Preface:
My f-series N55 PWG 6MT has been in great health and well maintained. I picked up a Pure Stage 2 turbo earlier this year and was running it on the stock fuel system with full supporting modifications. I initially planned to just run that setup for a while (and it was a fun setup!) but I felt as if I wasn't pushing the PS2 to its capability and I was missing out on some serious power for my specific setup. The fueling, specifically the HPFP was now the bottleneck... Anything over 16-17 psi (roughly) of boost on the stock fuel system would cause my fuel pressure to drop. Once I got more information on the newly developed XDI pump, it sounded like a nice fit for me.



Reasons I picked this setup over port injection or meth injection:
1. DME has complete control over fueling
2. I don't need to run an external controller to control fueling - JB4 and PI seems to be hit and miss sometimes as far as smoothness and drivability.
3. This pump is supposedly capable of 500+ whp and is ethanol friendly.

List of Engine Modifications:

• Pure Stage 2 Turbo Upgrade
• Pure Turbos High Flow Inlet Pipe
• Go Fast Bits (GFB) DV+ Diverter Valve
• TTFS XDI-35 Series N55 High Performance Fuel Pump
• AFE Open Air Intake with Dryflow Filter
• ER Catless Downpipe (w/ Ceramic Thermal Coating)
• AWE Tuning Exhaust with Performance Mid-pipe, 102mm Chrome Silver Tips
• CTS Front Mount Intercooler
• Evolution Racewerks Charge Pipes (anodized black)
• N20 NGK Spark Plugs Gapped at .020
• BootMod3 Software with Custom Tune
• 550i Clutch Upgrade
• Clutch Delay Valve (CDV) Delete

TTFS XDI-35 Fuel Pump

I worked with Frank and Gabe over at Tuning Tech FS to grab the new pump. These guys are professional and were very responsive to any inquiries (this should be an industry standard, though it seems very hard to come by in this industry). They supplied the new parameters for the HPFP to my tuner extremely quickly to ensure I had no hiccups during the install. Thank you guys!






Baseline Dyno
What good is it to brag about power numbers if you don't have a good starting point prior! Remember, every dyno reads a little different from each other so it is important to dyno and get a nice baseline to measure the delta and gains after, preferably on the same dyno! I did 273whp, 298wtrq bone stock and 383whp, 494wtrq on the PWG stock turbo on 93 octane (peak power was only at about 5k rpm then the stocker starts running out of steam - reason why I went PS2, but that's a topic for another day!)

I headed over to my friends over at Maximum PSI/Bimmer Clinic in New Jersey, where I do all my dyno runs and more complex work at! Great people and place. Time to throw the car on the dyno for a baseline



424whp, 455wtrq

Baseline Pure Stage 2 dyno on STOCK FUEL SYSTEM on PUMP GAS 93 octane. Both runs have the same hardware parts on them - Blue line is the stock tune, red is BM3 S2H 93 oct tune (running 16 psi at peak power.) Car is healthy! Top end pulls much harder then the stocker. I was really happy with the numbers on just 16 psi and 93. Please note: this is on the stock fuel system.


We spared no time after the baseline and it was time to throw on the new HPFP! Install was smooth, no hiccups. We loaded in the new tune file and car started right up. Car runs exactly the same as stock HPFP, no drivability issues at all... perfect! Time to turn up the boost!!




Feedback with the new pump thus far:

The TTFS XDI pump is holding 20-21 psi the whole RPM range on PS2 turbo. This is only on 93 octane

Still dialing in the setup, we just started upping boost and damn the car is a missile! This is a nice setup for even pump gas setup. Once we start throwing more octane at it (ethanol mix or race gas) we can bump the timing up more aggressively, but trust me the car is quite fun as is

Here is my setup from this morning - 20+ psi at 6.5k rpm on 93 octane pump gas - fuel pressure is perfect.

And yes.... we are planning an ethanol tune as well





I will continue to update this thread as time goes on.

Update 12/28/18



Here is a side by side comparison of stocker vs. XDI-35 hpfp. Both logs have same hardware parts (aside from the upgraded pump) and are both in top of 3rd gear @ 6k RPM (same exact speed too - that was actually a coincidence)

You can see the stock HPFP would dip/crash on anything above 16-17 psi (sometimes associated with a rough fuel cut and buck - I'm sure a few of you know what I'm talking about lol). I'm running 20-21 psi on the XDI-35 pump and no fuel pressure dips at all. Car feels real beastly up top at 20+ psi with solid timing too .

Dyno numbers coming

-----------------------------

10/15/19


Finally got a chance to hit the rollers again! 528 whp and 570 wtrq

Again this is with PS2 Turbo, FBO, XDI-35 HPFP, custom tune + supporting mods.

Runs were all consistent with and awesome power curve as well. Car is running FLASH ONLY and 93oct/boostane for these runs. Car is certainly a blast to drive!

No need to do the LPFP along with this kit?

I'll be running the stock LPFP for now, I don't foresee any problems with this. I've ran e30-40 all day long on it on previous setups (stock turbo).

How hard was the installation for the pump?

The hardware is a direct swap. You need a DME tune for the pump accompanied with it that has the correct parameters for the unit.

[arhoads335i]

Nice! Maybe I'll have to go to these guys for work in the future! Any dyno numbers with the new pump hitting 20+PSI?

[JaredG_F30]

LOVE it! Very clean. So what did it dyno at with the upgraded HPFP at 21 PSI?

Anybody running this pump and stock turbo? Is the stock turbo maxed out at 17ish PSI or can it be pushed more?

Thanks! No dyno yet, but hopefully will have some numbers on higher boost soon. 16 psi on PS2 was fun, 20+ psi is certainly a different level. The comparison between 16 psi vs. 20+ psi is as apparent to me as going from my stock turbo to PS2 setup so I'm pretty optimistic right now!

I am. You can hold 20psi but your turbo is working really hard. Dynoed around 450 awhp and trapping around 116 ( 115.7 mph) on 93 alone . Not bad for a pwg I'm not gonna say what a 50/50 mix does because people will be really upset.
My turbo has seen enough though...time for an upgrade
I'm expecting people to get crazy numbers out of the ps2 set-up with the hpfp upgrade. The question is ...how would the other parts hold lol

[Gr-Racing]

very nice numbers , my have to get the HPFP for xmas. ;]

sub

[insane11]

Group buy?

[JaredG_F30]

Thank you. Yeah part of me wants to get the HPFP first and just run the piss out of the stock turbo until it implodes then upgrade.

No worries man.
The hpfp along with 50/50 mix will definitely do some damage to stock turbo haha. But I am surprised how much punishment those stock turbos can take.

I really like where the community is going. Now, we can push the cars really hard and....we just need someone to upgrade the zf8 tranny internals and the transfer case for the xdrive guys.. because the stock ones are so absurdly delicate.

502 awhp and I can't really remember the torque accurately but we had to turn it down. Tranny and transfer case would be cooked.... actually,more concerned about the transfer case as the tranny can take a beating

PS2 set up will do great on a rwd. I bet OP will have a blast once everything is dialed in.

Very nice numbers and build OP!!

Im following a similar path with my PS2 being installed end of this month/ beginning of next month!! I'll be running stock fueling as well with MHD PS2 OTS tune which I'm told is targeting around 17psi

@F30_SixSpeed Dude...your car looks super nice. Keep us posted and if you can throw some draggy numbers out when everything is done ...would be awesome !

Thanks man! I do have a draggy but honestly haven't used it much. I'll try to wipe the dust off it

This is very exciting. 500+ whp with FBO + PS2 + XDI-35 on a 50/50 mix sounds like a really clean way to get some serious reliable power out of the N55.

So who is going to be the first to create a DIY installation video? I've looked at the diagram at realoem and at the replacement procedure at newtis.info but still have a few questions about this installation.
