I completely disagree with you cyotani.

okay

I never said I was right, just trying to have an intellectual conversion about manifolds. that greater than statment was a question if you haven't noticed...

So i'm curious why go with such oversized pipes?

Care to elaborate please? Speaking from a flow stand point. Not reliability, ease of mfg. and what not.

But if that's your argument for what makes one better than the other, I suggest you look closely at OP's #1 and #4 as well.

No nuclear powered turbo? No interested.

Thanks 888a, I actually have no idea why I was banned, but its MT, you get that.

The issue is the wall thickness of the pipes and the amount of weld protruding inside these pipes, and the fact that it has a much higher surface area.

So in essence, its larger and lets more heat escape lowering efficiency by lowering enthalpy, and I doubt it flows as nice as the smooth insides of the basic log manifold.

Anything here flows better than the steampipe log with the outlet hole cut in it. Hell, a cast log flows better than the steampipe logs because there is some attempt at directing the outlet gasses.

I'm not sure if you are refuting what I'm saying because you genuinely considered it and think something different or if you are just being facetious.

Whoa. Shit.

Cool it with the big words. I don't know what they mean so i'm forced to take offense at them.

nitrodann 09-05-2013 02:24 PM

so then?

got it, I was more just considering flow pathway.

Typically i don't post things I've created for the first time, but I felt happy with the outcome.

I gained quite a bit of knowledge just making this "diaper" of a manifold. When I order the pieces for the new manifold more time and effort will be placed into it. Plus I now have a jig and that was the most important part, now I can take my time with the new one.

It does look like a diaper now: or the scarecrows head from the batman cartoons:

I'm not sure why I decided to go with 2" pipe, originally I was planning on 1.75" but I just kept bending the 2".

Props on making that jig. What type of welder did you use? Obviously it was mig, but I mean, was it a small 110v unit?

The welder I was using is a millermatic 252.

Sure, if you don't mind the lack of flanges on it. I launched it into the scrap container from the back of a beat up s-10 from 100 yards away using a large water balloon sling shot (the sling beast). but I'm sure I could dig it out.

Just let me know when your in town and you can swing by the shop to get it.
