Alrighty so this is working out quite well so far. The tank has a reinforcement plate spot welded in 6 spots surrounding the hangar mount. These 6 spot welds just happen to line up perfectly with the aftermarket hangar that I have :).


Here's that reinforcement plate that was inside the tank. Had to be removed so that the split ring mount could be used in its place. It was easy enough.


Last, here is a preliminary look at the new hangar, these straight fittings won't be used. The fittings are 1/4" NPT and I have 6an adapters installed. I also already have the electrical bulkhead fitting installed as well. Just waiting on the venturi pump which should be in today and then I have one final order to submit from McMaster to get the rest of the hardware.

Finished up the hangar. The theme is PTFE...everything is PTFE to withstand ethanol. Even the shrink wrap is PTFE and sealing. I have an order on the way from summit with the AN fittings and AN hose needed to wrap this up and install the tank back in the car. All of this crap for a return line restriction. On the plus side, everything in the feed and return is 3/8" vs the factory 5/16" if it's even that with those tight kinked bends (especially on the factory hangar). If I need more fuel I will now be able to utilize a surge tank no problem.

Managed to get that all in there, took a little bit.

O-ringed the bolts

Bam! Final product.

For good measure...

And here is the jet pump pickup...good ol zip tie

I did a test on the effectiveness of the venturi jet pump. It was able to pump 1 gallon of fuel to the other side of the tank in 36 seconds with fuel pressure holding solid at 43psi. There was a fu*king tornado in the tank lmao. Very impressed.
I've added a turbine back pressure sensor and a 3 port boost control solenoid. All plumbed and wired in...

What’s the idea with das loopinator?
My guess is heat, helps protect the sensor probably

Throwing a guess in for vibration resistance given that it’s all hardline

Correct, the loop serves to dissipate heat from the exhaust gasses passing through before reaching the pressure sensor. It also dampens the exhaust pulses as they pass through the tubing and absorbs vibrations. I also installed a 0.04" restrictor/damper just prior to the sensor just to make sure the readings are stable.

Been awhile, here are some updates on the car.
Finally got around to installing the remote brake bias adjuster.

I got some new front wheels and tires. The tires rubbed on the factory wheel well liner so I made some new ones from hdpe. They clear with about a 1/4" to spare! Don't mind the socket spacer, I have some proper spacers on the way from McMaster along with some button head screws to replace those hex heads.



Yes, transmission jack...the spring is removed.

Clear when turning under load too?

Well if having the spring removed and the shock completely compressed counts as “under load” then yes. Lol

Just wanted to check lol. Didn’t see any pics of the wheels turned

Shit and I worried that 245s wont be enough for my m42t e21
Will 16s clear stock e36m3 or e46 330i brakes?
There are some 16's that will clear e36m brakes, but not the majority. As far as I know, no 16 will clear e46 330 brakes as they are slightly larger than e36m.
