hey thanks, manNice work!
The plan is to use a single 90 elbow from turbo to throttlebody. It should make more sense visually in a couple weeks. :beer:This is a super cool manifold.
Any reason your using a side entrance throttle and not making it rear entrance, so you can come directly of the turbo?
I think you're right about the contaminated cast. I'll try pre-heating and non-chlor brake cleaner. :thumbup:I am no expert by all means, but I first started welding Cast AL many years ago. While I saw you are using Thoriated (based on prev page), I have had more luck on Cast with either pure Tungsten (non-Inverter), Ceriated or recently Lanthiated
BUT, with that being said, it really looks like you just have contaminated Cast. Cast, will absorb oils. Non-Chlor brake cleaner and pre-heat will usually vapor off the contams. Glass Beading will also make your like easier with cast!
