Here's how I ran the crossover... right into the front collector between Cyl. 4 & 6. Basically its just a piece of a Mandrel U bend, but I have a lot more work to do on it. I think I am going to cut up another piece and weld it right over the top because the mandrel bender causes the metal on the outside of the bend to be thin.

 

this is the second time you've had "manifold problems"...just sell your POS VE!

just playing good work man, keep it coming!!

 

how about using a thicker piece of pipe for that piece instead of trying to graft on another piece on top of it?

 

I couldn't find mandrel bent pipe thicker than 14 ga. Its pretty thick stuff. If I was to really do it right, the only thing from the manifold I would be using is the flanges and I would get the cast iron piping that you weld together. It would last a lot longer/permanently. As I have it set up right now it may be pretty susceptible to cracking. I cut the mandrel bend a little short so there is about 1/4 inch of weld closing the gap right at the tip of the pipe so that is what I want to reinforce. Also when I was cleaning up the area with the grinder I think I ground that area of the pipe too thin to withstand all the heat. I really want to get this done by the end of Aug. so I can focus on school, and maybe I will redo it later with better quality(or if it becomes worth marketing).

 

gotcha.. makes more sense now. I agree with the "graft" idea ion that case.
