Yea it's the single not the dual.. I just order the 35.. Haven't even put it on yet.. Might have to return it to get the 60 now

[Marlinman]

Reliability-wise, I'd stick with 35 pump. You really need to consider doing more to that engine after you hit the 600 mark IMO.

Excited to see that your are also PWG. Who did the mapping of the car? I need someone who knows his way around the finicky PWG （not TTFS).

Working with Halim. He's a great tuner... really knows his shit!

[F30_SixSpeed]

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

[harkes]

Looks great! Logs will be shared once tuning is finished?

[hardparker]

More octane and more boost, please. I'd like to see where the XDi-35 pump's limits are. It would be nice if it would allow you to max out a PS2 on a high ethanol mix.

Ha! I've been running mostly 93 pump. I'm on e25 now and may work that up a bit.

I had a FB chat with TTFS concerning the XDI-35 and 60 pump. They stated the XDI-35 is good for 500hp+ while the XDI-60 is good for 700hp+ .

Per our conversation, they stated "...the Xdi 35 is perfect for E35 blend. There truely is no point in adding more E85 than that, the power will be about the same. the Xdi 60 can do full E85 (pointless but it can) like i said no need to go past E30 but you can."

They also stated PS2 is being maxed out with the XDI-35, and OE Engine stock internals have yet to be maxed out, stating "...nobody has made a turbo big enough to really push this motor to break something lol " ..

I personally disagree with that last statement as they don't have R&D data to support this...bottom line, I'll be DEFINITELY following F30_SixSpeed 's footsteps as I believe the XDI-35 is PERFECT for my long term reliability goals.

Selling used

Those return fees can be a killer.

thank you for this info.. i was gonna change to the 60 but i ll just keep the 35 now..

“XDI-35 E35 makes as much power as E85 in XDI-60”

“XDI-35 good for 500+ and XDI-60 good for 700+“

I’m clearly missing something.

This is probably clearer and what the message was suppose to portray. Many say ~e40 is as effective as full e85 for overall power output and octane rating (all other factors aside)

“XDI-35 good for 500+ and XDI-60 good for 700+“

I’m clearly missing something.

Response in bold.

[harkes]

I am gonna try and build my own. Just bought 2 pcs second hand for 60usd

[BeeEyez]

@F30_SixSpeed just out of curiosity, do you have to install the XDI-35 to get the option in BM3 to switch to that HPFP? I cant find it in my map options. I was hoping to see it so that if I go the route its not an issue when flashing.

otherwise, great build and fantastic numbers! congrats!

[JaredG_F30]

Please explain to me how this is true? E40 mixed with 93 octane gives you about 98 octane whereas full E85 is about 105 octane. More octane = more resistance to knock = advanced timing = more power.

Try the computer to configure the map and then save, the phone app doesn't have the pump setting.

Knew this was coming lol. I don't want to get into this, but studies have shown that a certain mixture... let's say 50/50 mix (e50) can provide just as much benefits, allowing motors to approach MBT at higher compression ratios and achieve a good percent of the benefit from running E85 or E100.

This was quoted from a study:
High ethanol blends have been shown to permit higher CR operation. Caton et al. [10] showed that for E85 blends, the maximum brake torque (MBT) spark timing could be maintained up to a CR of about 13.5, whereas MBT could not be maintained for gasoline and E10 past a CR of 9.0 in a modified CFR octane rating engine. Nakata et al. [11] showed at a CR of 13.0, MBT timing was knock-constrained for E0, E10, and E20, but not knock-constrained for E50 and E100 at the tested conditions. Stein et al. [12] evaluated a dual fuel system, where gasoline was delivered through a PFI injector as the primary engine fuel, and E85 was delivered as the secondary engine fuel as-needed to prevent knock. It was found that under turbocharged conditions with a 12.0 CR configuration, the maximum amount of E85 required to prevent knock at peak load was less than 60%, which is effectively about E50. The work here is unique in that it investigates, in combination, the effect of several high CR in an engine with DI fueling and with ethanol blends.

Well we know who tested the first Big Turbo on M235 Luminous and he pushed the boundaries lol. He also found out that N55 PS2 (the hard way) cannot handle 25psi for more than 1 or 2 drag runs or dyno glory pulls.

Tuning has developed insane in the last 2yrs and since day one PTF has been able to make as much power with conservative boost/timing than others running more aggressive boost/timing I've noticed.

F80Paul whats your thought on the comment in regards here E35 being perfect and no point in adding more ?

[1SER135]

Will you be posting a Dyno of what you achieve on 93 with the ps2 and xdi?

I want to go down this route with my m2
