Thanks for the great reference and info Torinalth! Im definitely only sticking to E30. Here in CT we only have 1 E85 gas station and it's 1 hr away so I cant do half tank fill ups unless I have a tanker parked in my back yard.
If my tuner recommends an upgraded FP to get an extra .05 hp then Ill definitely do it.
Also you should get a dragy if you don't already have one. I like doing before and after any mods. The street is your drag strip.

oh I do. I've been playing with it, but honestly Dragy has been somewhat unreliable in my experience. partially in part due to non-ideal road conditions that seems to screw with its tracking. I'm still trying to figure out how best to get my timing with my location, schedule, and everything else. I do NOT have the best setup for getting exact repeatable perfection. but I can test to show differences even if not viable for comparison to other people's cars.

_ink - since I didn't say it previously, congrats on the new pump and think you made a good decision with DE.

so quick compilation on virtual dyno. not the best, but i'm working on getting cleaner logs so I can make better comparisons. hate how the boost/afr plot on the bottom is cut off.... not sure how to scale it higher. and i'm working on the rest of the e30 tunes over the next week weather permitting. Of course note, that this is JUST tune differences, I've got all the same hardware in my sig for every log/plot. but shows how the upgraded pump and tuning can go a long way

Try uploading your logs to datazap.me it's a great online interface to use with awesome graph plotting, and all accessible online

The increase from the HPFP/e30/tune is impressive! Even more impressive is where the power starts @ 2500rpms, and carries throughout the entire rev range - very usable power increase!!

Hi Torin,

I am a new member here, my X3 M40i is just about to arrive, I plan to go stage 1, then straight to stage 2+ (with a Dorch) then likely onto a GC turbo.

Thanks for the info you're providing, it is very helpful, but a query about the power figures you have quoted.

On the BM3 B58 page the increases they quote are a lot higher than those in your graph: https://www.protuningfreaks.com/prod...0i-m140i-m340i

If we start with a baseline of 312 RWHP, stage 1 on 93 would take us to a max of 375 rwhp, with stage 2+ on 93 taking us up to closer to 450 RWHP.

The fact some M140i guys are well into the 10's on standard turbos would suggest people are making the kind of power figures quoted on the BM3 page.

Finally, do you use Dragy?

I notice the fastest X3 M40i on there (at 11.5 1/4 mile) is claiming stage 1, however I think it's a 2020 with a custom tune. I'm assuming its an E30 blend to be getting those numbers though.

WHP and HP numbers in todays talk of how "fast" your car is isnt a popular or accurate bragging reason. A 600+HP V8 today from the factory has high HP #s but on the street its slower than a 400hp car theoretically speaking.

11.5 1/4 in a 2020 M40i is very doable stock turbo.

And lastly we can never compare a 140i to a huge X3. Same hp for hp our 60-130 times are going to be much lesser as taking 5,000lbs tall and square to pull just as hard as a toy box isnt going to happen. Good luck tuning and getting addicted to this.

if it's new, meaning 2020+ you can probably hold off on the dorch for a short time as you will have an upgraded fuel pump already.
it'll be less than both the dorch 1 and 2, but it'll be a nice one to run till you want to go custom tune, larger turbo or more than e30 content

keep in mind that there is no specific number set for the G01, or the G20 for that matter that all make much more power than the original F30 based B58 engines originally. The stage 1 and stage2 number *increase* is based on the original 336 hp or so that the F30 was making.
This is why it is "up to X% over stock" because some cars make more from the factory so would get less increase.

If we start with a baseline of 312 RWHP, stage 1 on 93 would take us to a max of 375 rwhp, with stage 2+ on 93 taking us up to closer to 450 RWHP.

yes, but we never will. Suby01 said it perfectly. the M140 is ultralight and aerodynamic, vs our slightly curved box on stilts. between the weight and the size of our wind catchers we will never under any circumstance come close to the M140, or the 340 for that matter all else being equal (tune and hardware being same). I've gotten 11.8 in the cold on stage 2 E30 and will see how I do in the cold this winter on my new map and hardware config I have now. I should be able to pull 11.5, but i also don't have perfect roads to test on, so my numbers will always be dirtier that someone on a flat strait highway.

see above, and I have no idea about the other guy and what they are running

Still deciding on custom tune route..I'm amazed by how much these tuners charge on this platform vs the older platforms..

How was the install PNP or you had to force some parts back in to make it fit? Did you install it and run with no time just stock maps?

The install was very straight forward, all PnP and everything went according to plan.

For G01 installs be sure to let Dorch know, as the LPFP line is longer and requires x2 90 degree fittings. Credit goes to Torinalth for pioneering this and pointing it out.

I flashed the Stage 2+ map, which allows for the Dorch to be selected.

I'm 2018, MHD Stage 2+ flash.

It would depend on your ethanol blend/power goals. I used to run a JB4 + MHD flash combo on my N54, but Flash only is much more simple if your not doing auxiliary fuelling like meth or PI.

Not seeing recent updates to this thread, hoping the car is still going strong.

Found this thread along with one below,

https://x3.xbimmers.com/forums/showp...3&postcount=16

Counting myself as perf modder, irony is that done on the wife's car (she still won't let go of her 2002 honda odyssey)...

Ordered the stage 1 (not stage 2, no plan to go past 500 rwhp ) Dorch hpfp, more for the PnP nature of install (don't like the idea of splicing/cutting wiring harness, although the extension could be hand made).

Will see how this goes, with

a) mhd
b) a/a downpipe (catted)
c) mst intake (just for sound)
d) e30 (no plan yet to run >e30, until hardware flexfuel support on gen 1 b58 from mhd, COME ON MHD !!!) with fuel-it E content monitoring

If can hit 500 rwhp, or come close to, call it done.

How much difference do you think the Dorch 2 made? Just ordered one today. Running E85.

It will allow you to run higher ethanol content (full e85), and to get the max benefit of that, a custom tune (which I've been meaning to do) will see the full potential of that. For now, I'm only running the stage 2+ map which has made 304kw atw.

So this translates into just over 400 HP? Sorry you running E85 or not? According to my sport gauges (I have no idea how accurate), I am generating 415 HP with MHD stage one, E85, with no downpipe or Dorch yet installed.

Yeah I'm running e85 for that dyno, don't pay any attention to the sports gauges either..

Ink I think you are running a MHD Stage 2 E85 map? No? Did MHD customize the map for you. I am now sitting in my office with an AA catted downpipe and a Dorch Stage 2 asking myself if I really want to go down this path. I am running full E85 with no other mods and the car is pretty damn fast and I won't have to convert it back to stock on sale. Dumb question, but are you glad you made the mods? If I am converting your numbers correctly - which I doubt- I feel like you should be making much more horsepower…like close to 500 hp. I am guessing this has to do with atw measurement versus at the crank? How is driveability? Do you ever throw CELs? How is your fuel economy? I have taken probably a 30% hit running E85 which is not trivial.

Checking out the guys at Protuningfreaks it looks like they might have a more fully developed product than MHD (customizable hpfp Dorch 2 settings). Any thoughts?

But from the lack of replies, this pretty much answers itself.

Wifes Dorch Stage 2 going in soon. Already have it in-hand, just waiting for a cool day to do the install and flash the appropriate tune, plus do oil change and xHP Stg2 flash as well.

Hoping w E50 her X3 will be in the 11.3/11.4 range. I've seen some folks pushing 11.0 with this setup but lighter wheels
