So here's a a picture of the map and of the exhaust. I either got the spark table from somewhere on here or used one on here as a reference, can't remember. The cast flange was hard to weld on, let's see what you guys think.

why are you running such low timing in the non-boost cells?
and that dp design is pretty bad for flow

as for your bad quality question: manifold is one of the most important things in a build after ecu and injectors. that's why

You;re going to get tonnes of failures. Basically its going to fall off.

Yeah I had a hard time with that downpipe without trimming other stuff. Oh well. Did what I could. The tune is just something I thought would be pretty safe for now

What radius was it? It looks like you have more room, and you can trim the shelf back a bit before it opens up to the hollow cavity, I think.

Edit- nm, it doesn't really matter, you'll have a new mani soon.

I agree with you I should have trimmed the shelf. Ran out of time and figured it would have to do. Obviously it's not the best for flow but I think it'll do fine

Okay well, I think I'm going to stop posting here as I haven't gained any useful knowledge from this thread and anything I need to know is elsewhere on the forum, but I will still eventually update this when something breaks or when I have dyno sheets

The exhaust looks better than I could have done and I can certainly respect the DIY effort that went into it. Looks like a pretty solid first attempt to me. I'm interested to see how it holds up.

In for -50 prop cats.

I'm not sure what to tell you. I couldn't disagree more. The only thing I have learned is that buying a cxracing manifold is a death wish on this forum, and that people don't appreciate things that don't have a clean appearance no matter how mechanically sound they are. I will still update it periodically for anyone who is actually interested in failures etc.

if you could read between the lines, you've learned your spark map is ridiculously retarded.
