So, I will start with the latest addition to my build, which is Direct Port Methanol Injection from ProMeth. At this point I personally think methanol really helps our engine performance and keeping it clean, I have been injecting meth for more than 20,000km, and when we opened the engine it was surprisingly clean! And since I spent much time this time on making the valve ports shine, I really want to keep them like that.
I started planing the direct port a few months ago, and did quite a bit of research on different kits available to make this happen. Also searched the Mini forums to see if someone did it in this engine, as direct port it's getting really popular specially with BMW n54 engines, only found one user who did it and there was no feed back from him...
I wanted stainless steel lines, and an fittings and a clean install, ProMeth did not have a kit for our engine, so I had to take some measurements and contact Rodney who's a great guy, and was really helpful putting a kit together with everything I asked for.
Kit contained pre-bent stainless steel lines, braided stainless steel hose, -4AN Fittings, 4 nozzles with filters, 2 check-valves at the T connection, 1 check valve at the Main Connection, and the pressure gauge.
The reason for having this many check-valves is as I don't want to run an electronic solenoid in the system as most of them can't take more than 20 sec of continous operation and i dont like that.
- Made some plastic bungs to mount the nozzles as it doesn't feel right to tap into the thin manifold plastic (although many do that).
The bung has a hole on the inside so it would not interrupt the flow of the meth nozzle.
- Nozzle with filter
- The Koala Manifold Spacer, this too has meth injector bungs but they are on the back side, and since nozzles need servicing, I didnt use it for mounting the nozzles, instead this pushed the intake manifold for 1'', so I had access he flat space to work with, without the spacer I couldnt do that as our manifold sits at an angle.
-Cutting the tubes for perfect fitment
- 1/2 done
I am currently running the AEM Nozzle (250cc/min@200psi) on the charge pipe, and 4 ProMeth Nozzles (4x 33cc/min@200psi) on the manifold. That would total at 382cc/min@200psi, but since I am using 4 check-valves in total the system is down to ~120psi, and the total flow is down to ~230cc/min. I have some bigger nozzles waiting if I need them when I continue with tuning.
Next weeks will change the exhaust with 70mm one as it has started to become a restriction now...
Cheers
