TTFS is selling the XDI Fuel pump upgrade for the n55, supposedly flows 36% more then the stocker... which as we know is a bottleneck once we start throwing more power at these cars.

A little pricey for what is it, but I'm interested in it as my setup (PS2, FBO, stock fuel system) is maxed at about 17-18 ish psi running 12.0 AFR... any more boost my HPFP starts dipping/crashing. Does any one has real world results (not shop cars, etc.) on this upgrade? Post them up!

Personally, I think you may have trouble finding a tuner to deal with it short of TTFS with their flash. For me, it seems like the same reason I haven’t upgraded to the Speedtech turbo kit yet. Just a lack of tuning support. I’m lucky enough to have just found someone to tune a FBO EWG N55.

MHD is working on one.

[cookiesowns]

MHD has it in testing, I've been following them for a bit. Works great. Pushing 18+ psi holding strong at 2300psi with plenty more room at 12.6 - 12.3 on PS2 EWG which flows quite a bit more than PWG PS2.

They will be coming out with a flash time option for this along with an 8AT torque limiter bypass in 3rd & 6th.

You won't need a tune from TTFS to get it done.

You're looking in the wrong place then. There are many tuners that can do these cars. Some more reputable than others. I also do either BM3, or MHD, or even OFT when the xdf's and platform is finished.

The cool thing with the speedtech kit is because it's a IWG BorgWarner EFR the compressor maps are available for the car... it will make dialing in the base compressor characteristics map slightly easier, especially if it's EWG. Will be easier to tune than the PS2 100%.

Yeah, I just gave up on that idea. I will finish my current custom 93 octane tune and my methanol tune and call this platform good. I’ll eventually move to a competition M3 next year and take those go fast parts with.

http://tuningtechfs.com/ttfs-n55-hig...p-single-pump/

I'm running their pump set-up for a long time and it's great. As far as boost level goes...it's more likely for you to blow other parts apart before running their HPFP out of capacity. That should not be a concern whether you can achieve more boost...because you can.

The pump is nice and solid, no plastic shit like the stock one.

Trap speeds of 116 mph on 93 octane, stock turbo are achievable but I'm xdrive...fat, heavy car. However, the stock turbo wouldn't last long if you crank up the boost to 25 psi and up and you beat it every day..mercilessly.

I daily my car and I have no complaints. If you have PS2 ...It's going to be different feeling for you. If TTFS tunes it, you could probably get 490-500 whp on 93 octane alone....no meth, no E85. ...but then again,you are pushing the car hard

I think a few tuners are able/willing to tune the pump. cookiesowns is able to, he replied in this very own thread

You have the S55 dual pump setup if i remember correctly? I am more interested in the single HPFP upgrade.

Also - glad you are happy with your setup... how come no dyno results, track times, videos, etc.? Is that so hard to do in this day and age of smart phones

EDIT: NVM - i see you have 400 AWHP on stock turbo and 93 octane dyno graph from TTFS inflated dyno. The graph and power curve doesn't even look like an N55 engine, so it's not a realistic visual for me, sorry. Why not get a few pulls on an independent dynojet (what most use on our platform)... it may be to your benefit as well to see exactly if the claims are what they are supposed to me. I understand you are happy with your cars performance and tune, but going from stock to a tuned car is a huge difference.... butt dyno is hard to calibrate. I'll donate/paypal you $30 if you dyno your exact setup on an independent dynojet. Would be cool to analyze the difference.

I have the single HPFP. The graph that was posted was an old graph when I initially tuned the car, after that the HPFP single pump upgrade was installed. The M2 has the dual pump. I'm not trying to convince anyone...I'm just saying what I saw. If you like it ..it's ok....if you don't it's ok too.
We tested the shit out of the stock turbo for the single HPFP. Reason why you see no track times is because the turbo went bye, bye and I'm in the process of getting a new, upgraded one.
I'm not really a huge fan of dynos but I am a fan of trap speeds and 100-200 km acceleration times. I appreciate your kindly offer for paypal but money is not an issue. I bought Dragy and once I put the new turbo...I will share some results along with drag strip times.

I have vbox numbers that will be questioned by everyone and frankly I don't want to come across like a marketing guy. I'm sharing what I saw on my car and on a PS2 car.

440 whp on stock turbo with 116 trap on xdrive 93 octane only...no additives. However, as I mentioned before, stock turbo will not last long at those power levels. To be reliable...I would say 400whp.

I was trying to say to you that you will not max out the signle HPFP capacity even if you try on 93 octane alone. I would be really concerned if you have an automatic tranny and you are trying to push the car because they will make 500+ tq at the wheels on 93 alone.

Anyway, good luck with the car ...PS2 is a ball of fun especially when it's rwd.

Ahh okay I didn't realize you had the single HPFP upgrade. Looking forward to the draggy results ... I have one too, but admittingly I never really use it... I will try to more often.

I know Frank is tuning you... so "tuner war" aside, has it been relatively easy to dial in the actual HPFP portion?

Are you upgrade turbo or replacing stock turbo?

Agreed my man... I like this as well.

I think it would be a lot more popular (and they would sell more/ ultimately be a lot more profitable, despite less profit margins) if they just dropped the price $600-800, but I understand their approach on their side of the business. Perhaps they may do a group buy or discounted starting price. Time will tell.

Makes me wonder also what the Speedtech kit would do for our cars.
If you get the fuel pump and raise the boost it would be interesting to see you and Rob run again. That may be all the difference for now. But my feeling is a better turbo system would be more advantageous to you giving these modded F80s a run for their money if you get in that deep.

Nah I'm good... very happy with Pure Stage 2

[Stanio]

I was pleasantly surprised by Dragy...once I managed to make it connect to my phone because I had some issues with that.

"Tuning wars" aside (once I realized that there are a lot of tunners on the forum dissing everyone off) Frank spent a lot of time making the XDI pump work so I don't know all the technical details about the parameters. However, I can tell you from a consumer stand point that It holds high boost really well and doesn't cut off the throttle like the stock HPFP. I drove the car really hard and it was insane. Once I lost a lot of power and saw that the turbo is pretty much dead ...I drove the car normally and even fuel economy was on par with stock..or it was just me driving close to the speed limit(not that you would care about fuel once you start pushing the car hard). I would be careful of pushing too much boost though because our cars are ..delicate.

About the turbo...I don't know man, I'm 90% certain that I'll get an upgraded one but I just don't know what. I've heard mixed opinions about Pure ...and there's not a whole lot of feedback from the other options...Speedtech or Big Boost. I am slightly concerned about the tranny and transfer case if I upgrade the turbo because I've seen what numbers they put up on 93 alone and it's kind of scary for xdrive guys with the ZF tranny. Especially when you hit the 500 wtq barrier on 93 ... I think the tranny will have serious issues if you run it past that number and you daily the car, beating it hard...like I do/did.

I had the pleasure to drive the same car like mine but it was a rwd with the PS2 turbo and the single pump upgrade. It was soo much fun...I wanted to throw this xdrive crap immediately....but maybe next year.

How is your PS2 hanging on ? Do you have any issues with it ?

Keep us updated! We like results, videos and dynos

I'm loving the PS2! It's a great turbo and it appealed a lot more to me as it's direct bolt on, unlike some of the other kits. I'm RWD and 6 speed manual... only thing that concerns me is I will probably need to upgrade my clutch one day, but its held 450-500lb of trq for a while now, they are a lot more stout then people give credit for.

If the HPFP upgrade allows PS2 to run 20+ psi of boost with proper octane and E... I'd say 480-500whp is definitely obtainable pretty safety, which would be terrific for my goals. Anything more then 500whp, I would have went with the speed tech or other turbo kits, but I don't know my friend is running the speed tech S3 kit and can't seem to get it running correctly. PS2 is known and proven.

My goal going into my current setup was to trap 118-120 on PS2 and stock fuel system (fyi I trapped 113.5 on stock PWG turbo, FBO and e30.) I just ran my buddies brand new M3 ZCP and had some really nice runs... I would crawl away from him and hold off even up to 160 mph. They consistently trap around 119 and dyno 430-445whp bone stock so I'd say my car is running pretty strong! top end pulls hard (I'm at 17-18 psi and nice timing but at the limits of my HPFP, it dips occasionally but doesn't effect drivability and its fine, just definitely being pushed a bit lol)... I'm getting boost dip post shift and thats really the only thing I'm trying to iron out (thats on the tuning end), but no real complaints as far as the hardware is concerned... i recommend PS2 highly. Doesn't matter what turbo you have, right around that low-mid 400s mark, you will run out of fuel unless you are getting supplemental fueling from somewhere.

Thanks for the feedback man.

Yeah, being rwd and manual you can definitely push the car harder. Stock hpfp sucks...I remember when I first tuned the car and went on the track. I had so many dead spots when the stock hpfp failed it was really annoying and that affected the trap speed.

PS2 seems to be the best option from those 3.
That's really strange about the speetech kit. I looked at their website and it looked really promising...nice, solid build as well. Higher price but I really liked their manifold.

I think 500 whp for you is a done deal with ps2 and upgraded hpfp but be careful with the boost ...it's really addictive and damn...parts will break lol. No idea about the stock cluch...I guess one way to find out.

All I need is some guy running 500+ whp and wtq that has xdrive and can let me know what to expect ...what will break first tranny or transfer case haha

Will be very interesting to see wants you do your fuel mods. I think the dealer is asking about 2k for the stock pump as well for our cars so not sure if we can get around the 2k for the upgrade. That sucks but whattayou gonna do

I totally respect the blood sweat and tears you put not your beast though and as usual I will be following you San!
