Machined the injector ports into the manifold for Insanity last night. Also machined the fixture for welding the injector tubes to the manifold at the correct alignment, hope this works well. The injectors will sit in bosses (from Jegs) which will be epoxied into the injector tubes. I went with this design hopefully end up with a better injector fit and less welding distortion than on previous manifolds I've fabricated. More to come.
