Please help me understand what fueling option is best
So currently I'm Jb4 + bef on stock turbo. 2013 pwg 335i. I can't really run over e25 on map 5 without hpfp crashing. I have walbro 450 lpfp too. I plan on getting ps2 in the spring. I was thinking of buying a burger wmi kit to allow me to still run E30-40 now. But will this also work well with the ps2 to hit my goal of 500+whp? Or do I need more/better fueling?
So basically will I be throwing away money by getting the wmi kit now because the ps2 requires PI or something like upgraded hpfp to hit 500+? I'm just still confused about the fueling side of things because there are so many ways people seem to go. Anyone running full e85 on ps2? |

PWG PS2 here. WMI kit has been treating me very well the last 4 years. Only WMI related hiccups has been from running JB4 and a failed WMI solenoid. Both has now been replaced and the car is driving flawlessly.
Running 20psi to redline with 11 degree timing on 100% meth and 93

So I'm leaning towards hpfp. I'm real close to just ordering Dorch stage 2 and calling it a day so I can run all the E85 I need. Just looking for more info to see if the stage 1 would be good enough to get 500whp with 93 or a small E mix. I don't want to get stage 1 and then find out I still need PI or meth to hit my target. Seriously appreciate the response though |

VirtualDyno says ~440whp which is good for 100-200kmh in 7.3sec (BMW M135i). See this video: And here explaining my setup:

I have my setup ps2+jb4+mhd bef+wmi for 2+ years I think now without issues. Even that I have the xdi phfp for 8 month now and I haven't install it. Not even sure if I will, so if you want it I may put it up for sale.

Thanks for the offer! I ended up ordering the bms wmi kit with 3 gallon stealth tank today. I needed to hear some positive talk about the wmi on these through the charge pipe and u guys definitely helped. Figured it's always nice to have the option of spraying meth even if I get a hpfp for more E85 in the future. Perhaps I find the meth to be enough. Last question for now, you guys running a mix or full meth? I need to find a local source for meth by the gallon but for now I ordered a few cases of boost juice. I never ran more than 50% on my other car because I heard the AEM pumps can't handle it. Is the BMS pump designed to handle 100% or something because I've seen quite a few people say they were doing it? |

Crazy question here. Might be stupid, might be genius. Won't know until I ask.
What if I installed a good HPFP, LPFP, EKG, , a PI, and a WMI, full kits, then ran e85 on a custom tune? Would my N55 morph into an S55 or better? Anything to avoid upgrading the turbo. |

Sorry. You obviously don't know much about mechanics. Almost don't know where to start but an engine is an air pump with mechanical limitations with the turbo being the first limiting component when it comes to power

From my understanding... WMI and running E85 is basically the same thing... turbo is the limiting factor... If you run WMI on top of E85 expect a 5.5% (20hp+/-) increase... problem with E85 is it is not consistent and adding WMI will be more of a better controlled fuel delivery to max your tune... another benefit of WMI is it will clean up your intake valves... Corrosion is the only issue but someone else can chime in on that... I've been contemplating a port injection set-up... but adds significant cost.. $460 vs $1215 port... I'm just starting to get into this and not sure of additional cost yet... Another thing is I can get pre-mixed 50/50 meth 4 gallons on Amazon Prime Last edited by FastF30; 11-06-2020 at 07:50 PM.. |

What would the power increase be running WMI on stock pwg turbo? Hate this tiny turbo, trying to figure out if its worth to bother with WMI or fuel upgrades before a turbo upgrade.

FastF30 Yeah I was just messing around but WMI is going to be my next upgrade, if not HPFP with the new bootmod3 e30 tune. I have tons of maintenance to do before any of that though, like a good walnut blast. What are the pros and cons of PI vs WMI? Can you link that Amazon 4 gallons of 50/50 meth, please? quick_335i Look up the kits and they'll usually give you a ballpark for PWG. In my opinion, upgrading the turbos to anything crazy big is a huge waste of money. You have to really love the car and engine. You can make 800+whp easily with stuff bought online but it's going to cost you more than a new car. WMI is a great option and it's gonna feel like a rocket.

I found the best deal for the 50 50 boost juice including shipping was from Summit racing. Its a few dollars less than amazon. But if your looking for the best price to run meth you should buy a can of M1 and mix yourself with distilled water. You can send an email to VP racing and they will send you locations of local dealers.
WMI is a great option. I run 70% and can run 21 psi with clean timing and wgdc below 90 on my stock ewg turbo. IATs typically drop at least 20 degrees. If you already have a jb4 its a no brainer. https://www.summitracing.com/parts/sno-40008 https://www.amazon.com/Snow-Performa...ost+jui&sr=8-4 https://vpracingfuels.com/find-vp-dealer/ Last edited by 435gc; 11-07-2020 at 02:35 PM.. |

This is correct for PWG. Your gains with HPFP or meth will be minimal on a stock PWG turbo. You can get close to maxing it with completely stock fuel system. A bit more is left on the table with EWG, hence the new BM3 stage 2+ map and all the people going custom tunes before that, once they upgraded fueling in some fashion.
