With the effects of COVID and curfews from rioting I've been bored the past three months. I wanted to share progress with my build and some new hotness I've been testing and working on with @jyamona and @m18performance. This build isn't finished by any means (is that even a thing?) but I'll try to update this as things progress. I'll spare you the detail of maintenance related items. Here's the basics:
* 2007 335i 6MT
- JP(doesn't)workz hotside....more on this later
- Precision 6266 Gen 2 BB
- M18 Billet Intake Manifold & Chargepipe
- M18 Valve Cover
- M18 HDP5 HPFP Housing
- Radium FST with dual walbro 450's (with room for another still)
- Radium Expansion tank
And here's some pictures to get you started.
First off, lets talk about the JPdoesn'tWorkz manifold. I bought this manifold used a couple years ago and it must have been one of his first manifolds as the fitment was beyond terrible. I had to shorten both wastegate branches and weld on new flanges, one of the primaries had to be "massaged" with a hammer to clear the already custom water pipe, the provided wastegate dumps were useless and ended up being remade and finally the rear O2 bungs were welded on the wrong side of the downpipe meaning they were pointing at the floor of the car with an inch of room above them. I ended up have to cut off both v-band flanges, welding new bungs on and flipping that section of the downpipe. To be honest, I should of just made a new downpipe from scratch but oh well.
Moving on, this car is running an experimental dual HPFP system that @m18performance, @jyamona and myself have been working on. I can't say a lot about this but car has the factory N54 HPFP along with a cam driven Bosch HDP5 that is controlled by the DME. All connected with hard-line using factory fittings.
Another experimental item on this car is a MAC solenoid being controlled directly by the DME thanks to @jyamona. Frequency and duty cycle control were verified with my scope (see below). So far this is working very well with no issues and is providing smooth boost control while keeping the PID feedback loop intact (if you want).
Moving on to the fuel system, this car has more fuel than I know what to do with to be honest. In the trunk I have a 1/8" laser cut aluminum panel that's replacing the ABS insert. Mounted to that we have a Radium Fuel Surge Tank with two walbro 450's installed. The factory lift pump remains to fill the fuel surge tank and is still volume controlled by the DME with the factory EKP. The primary walbro 450 pump is volume controlled by the DME as well with another EKP. The second walbro 450 pump is relay controlled and actuated by the DME. Also mounted to this panel is an ethanol content sensor (running out of room in the engine bay...). Up front the car has a fuel distribution block for feeding both HPFP's and the M18 port injector fuel rail. Pressure is regulated with a Radium FPR.
Lastly I've replaced the factory expansion tank with a universal tank from Radium that's mounted to the strut bar via welded tabs. I tapped into the heater core return line and capped off the factory feed barb that's normally used to clean up the install and remove an additional hose that would need to cross over to the drivers side. I've probably forgot other things but that's all for now. Let me know if you have any questions and I'll do my best to answer them.
