Another update coming soon; getting close to start up. I wont be installing the fueling system until I can correlate a date with honorable Ken at wedge since he's able to tune the helix units. He also happens to be local to me. I attached a little teaser...

I like the crank bolt capture.
Thanks, I appreciate it!


With the drug dealer scale that has bits of wax all over ;) LOL

:tearsofjoy: At least it's not dark doodoo! lol

I have the exact same EBC, but I'm a noob at wiring. Where did you tap for power?

find the same gauge of wire. Pure orange is a constant power source, and brown is ground on almost all euro cars in general.
The positive wire I used is located on the DME Harness grommet farthest away from the firewall. The ground I used runs to the DME.

Here are some pictures. I just used wire locks 18-22awg.

Sorry for the weird angle, just follow the brown wire, the rubber grommet you see will be nearest to your stomach.

Heavy weather means a heavy work schedule for me. Also took a trip to the beach with the dog.
I'll have a decent update tomorrow.

I got a killer deal off craigslist of all places. I was lead to an abandoned property where the former renter had left a torn apart 335i... the homeowner said "$500 take what you can".. 😱😎 more on that tomorrow. Had upgraded mosfets installed, also had to take a step backward real quick, finished the psp900 install and it was a bitch kinda.

I had to modify the coil boots that came with a bnib PR coil kit purchased 3rd party. The kit was apparently an "old style" known to have boots that are "slightly out of spec"... albeit the item is outside of warranty for obvious reasons it indeed kinda sucks that it was a known issue that was once warrantied due to being faulty. I cut about 1/2" off each boot and they seat very well with plenty of contact to the insulators on the plug.

Also wanted to talk pcv with someone who speaks fluent in that language. I plan to purchase provent200 catch cans because I loved the one I had previously. They have a control valve that's pretty nifty if you're running a closed system, but im running vta and they may be overkill but damn do they filter well!

Dme works fine, but water was present at some point.

What valve cover are you using @MoistNapkin ?

I have the m18 and I just ran one of the -10s on the valve cover to the inlet on the speedtech kit. Draws about zero vaccum, but I have no smell, no leaks, and a cheap BMS style catchcan is keeping the inlet clean so far.

Thinking about switching to a radium can because I get them for cheap lmk if you want one :)

I'm planning on doing a pan evac setup soon, but yeah what VC are you running?

@JimboFresh206

Stock valve cover, stock flapper, pcv delete fitting, plugged head ports, VTT vented oil cap.

I'll get back to you tomorrow when my head is put together. Ive been under the basic impression that 2 cans were recommended, and my quick thought was to merge both the low/high side into one can rather than two separate ones. If one line can simply go VTA, or routed down the exhaust that would be ideal and save me time.

Update tomorrow after I make additional progress worth documenting here.

Update on Post #2:
  • 335D relocation and fortunate luck with a fitting that works perfectly.
  • Added to the PSP900 install.. some good details
  • MOSFET replacement
  • Revshift transmission mounts installed
I plan to start the car tomorrow, The only thing I have left are catch cans, and I'm ready for a shakedown.

Are you running Spool’s 10 micron filter and taking the filter out of the OEM HPFP? Will you be running a support bracket for the Helix as well?

I'm using an 8micron inline filter, and the holley hydramat is a 15micron. Correct, I won't start the car without all of the brackets installed. I'll do an update here in a day or two... llllong overdue.

Alrighty, this is long overdue. I've been getting work done, but not very internet active. Tt's also work season for insurance adjusters. Progress stopped when all the Helix OD issues were occurring, so I put a pause on things since this isn't even close to a daily.
.
Here I've installed the new helix brackets. I also removed the little piss poor inline filter the HPFP uses since I have the Hydramat, and the inline filter. Here I've fitted the new fuel line that feeds the HPFP as well.

With the Helix OD reinstalled with the new plate, and bracket I began working inside the fuel tank. These tanks are heaven compared to 30+ year old e30 tanks where people clean them for hours, and then POR treat them. The tank did have contaminants as you can see. Although it appears to be large-ish granuals, that shit is actually a very fine dust that's trapped in water. I emptied that tank entirely to make my pump install easier. This big ass Holley Hydramat fits when curled in to itself. Holley says this is perfectly fine. This will prevent any kind of starvation issues for the most case

So I had to revise the Bosch044 pumps to sit horizontally in the tank rather than the vertical orientation shown on the previous page. I test fit the pumps in a 335i tank I had given to me years ago, the passenger side reservoir is taller in the 335i's. My lead's for the pump's were originally made to length for the vertical fitment; Well now that that I've made the revision I about screwed myself, and definitely created some frustration for myself. Regardless she is in sans a fuel level sensor. I'll implement the sensor later, and since I have a totally full tank I can at least ball park my fills for now.

This is where I made my discovery of the pump lead's being short. I made them just long enough to shimmy my fingers down in there to connect both pumps, and the return. The great news is the return lines from the fuel sending unit sit directly over the hydramat.. that's nice. I had to modify the tree to make fitment work. everything is in though.
20200104_191800.jpg


I closed that hatch and began running the leads from the lpfp side. I repinned both pumps to run off the two OEM locations rather than tapping into the hat. I had to slightly trim the seal down to fit the new lines for the BPM4, but it seals as it should 100%.
20200110_170510.jpg


I kept all the fuel sending lines on the fuel sending unit on the driver side. It looks a tad crowded, but it all fits naturally, and I personally like the configuration. Look carefully and you can see the second feed leading to the top hat. The feed line has been crimped despite the picture shown.

My goal with the boost solenoid was to keep the lines short, clean, and away from the heat. I was able to nail down two of the three, but I'll be purchasing shielding protect the lines. I'm slightly concerned with heat soaking into the solenoid off the valve cover, but I think we'll be okay. I removed the filter from the intake side because multiple communities throughout the years see these get clogged much quicker than expected. I switch my line size up to 1/4" line, look at the stock nips that come with the 4 port macs.. pfft.
20200218_155307.jpg


This is where the lines sit, right over the exhaust manifold. The image makes the lines look excessively close, but they're juuust close enough to be a concern. Do not use line you can collapse with your fingers! Please use a line that's also somewhat heat rated, and then protect your ass with shielding.

Anyone who played paintball, or worked with pneumatic based poppet valves knows that lubes like dow33, dow55, and hater sauce are lifesavers when it comes to pressing in bushings, fuel fittings, and tight fitting holes. (heh) They're not petroleum based, and don't dry out quickly compared to mainstream options.
20200220_155013.jpg


I'll be using a Provent 200 catch can, they're simply one of the best can made ever They're found on several model's from factory, and have some amazing coalescent abilities. The PCV system I'll talk about after some tests, we all know how great these discussions are and how opinionated the subject can be sometimes.

I'll be using one can that runs both the high and low side properly while still properly running true vacuum at idle/decel without fear of the can becoming pressurized, or any adverse effects. This system uses a series of check valves, and a spring valve that cracks at a metered psi, this is installed inline at a T that has been implemented into the system. Sounds too good to be true, right? This should be badass for us if everything goes to plan. No one should ever need to use two catch cans ever again.. they'd be obsolete.

last but not least.. A 3D printed cap for the mhd wifi dongle, that way It can fit the port with the cover on rather than pushing the port back.

Another small update here, looks like I'm ready to give starting a try in the next day, or two.

I switched out spark plug's with 2-step colder plug's gapped to .022 for now.
20200224_163258.jpg


I bought so DEI heat sleeve to mitigate potential damage to the lines running between the mac solenoid, and the wastegate. The sleeves are great, but I unfortunately purchased a bad piece from them. I'd imagine DEI will resolve this issue quickly. Here you can see I've shielded the lines, and also the big return line on the Speedtech kit. The return line sits quite close to the exhaust housing.

I just saw this thread!! Dam how did you fit the thermostat, charge pipe and 90 degree coupling. I'm having a hard time fitting the air filter coupling, its too tight of an area. I have the PSP 900IC so I had to cut the silicone charge pipe to its proper size.

I've never seen anyone else go the ProVent route.
Good job on picking a great product.
