[NOTE: For anyone looking to purchase a metal outlet for the HP650's, @Rob09msport is working with a shop to provide an aluminum outlet to the retail market.]
This is a slow start, I know. We ran into fulfillment issues with our first stainless pipe supplier. Now moving on to order #2. We are going to build a few sets of these outlets in stainless steel. @barry@3DM is up to his eyebrows in building Ohlins setups for BMW, but I do get some of his attention when I get to where I need his assistance
. I'll just start with a few pictures from today, and we'll update this thread as we get stuff in and build.
These are being built with 1.75" OD pipe, ever so slightly oversized on the inside of that pipe vis-a-vis the 1.51" ID of the @Hydra Performance HP650 turbo outlet. If I convinced @barry@3DM, we are running a slightly oversized splayed join pipe and slip them on the 1.75" OD pipe, so the splay will be 2" 0D to 2.5" on the join side (which is correct for the FMIC hookup.) We'll use a 2.0 OD" inlet (circa 1.88" ID) because a splay inherently reduces area once the splay cuts away at the two feeder pipes. Buy going to 2" OD splay feeder pipes, we won't constrict the volume relative to the feeder pipes and the splay constriction. A few other small notes. The pipe connections at the turbo outlet will actually be a larger section of 2" OD pipe (e.g. ~1" long) swage fit to the 1.75"OD pipe. That piece of pipe will have a bead run 360° for both the outlet joins to the turbo. This allows a more natural OD transition to the turbo outlet and the ability to run the bead tool full circumference which cannot be done on the tight bend turbo connection (see how PSP does their tube bead, for instance).
We've got an N54 mule on the stand for the work. Today I pulled stock parts off the N54 long block and installed the HP650s. You can see Barry already made a jig to locate where the outlet needs to finish up.
