Not really a 'today', more something I've been working on for a little while.
Turbo manifold on the race car was starting to be a PITA and needed cracks welding up on a regular basis. Inspired by a Youtube video on getting manifolds 3D printed in stainless I decided to have a go...
The result of far too much time spent in CAD:
Printed out a couple prototypes in PLA to check fitment etc, then committed to getting it printed properly via JLC3DP. Once it arrived I discovered that they'd done a proper half-arsed job of removing the support material from inside the Cyl 1 and 4 runners so had to spend a few hours jamming various tools down there to get it all out. After that sidequest I got a bit impatient to get it on the car so didn't get as many pictures as I planned. Here's one of the old battle scarred 'log' manifold I made a few years back along with the PLA prototype in the background and the stainless one.
It's all in the car now and ready for testing at the next sprint in a couple of weeks time. Hopefully it doesn't fail immediately
Already started work on designing the next iteration to support a possible turbo upgrade (Fundamentally the same, although it has a V-band on the outlet instead of the T25 flange (Looking at going to a G25-550, or most likely the PSR equivalent). Might also need to move the turbo off-center slightly to help with packaging.
