1st plenum
Here's teh start of a plenum that I'm making for a project.

Maybe it's the angle, but that looks like it is going to be too thin. Made a gas tank out of that stuff and when we pressure tested it at 3psi it blew up like a balloon. I almost want to say you can see it warping/bending already, but I've had a few beers (it is Easter morning after all).
Those welds wandering around on the long flat section like that will probably leak air too. They can look perfect and still leak. If you're running a speed density system it may not even matter though. Around the tubes look ok! |
Its 20ga. I will pressure test it once its boxed. Thanks for looking More pics to follow

20ga? Like .032"
Sheet Metal Thickness Gauges I would consider that a temporary piece. Even if it's not boosted repeated cycles with welded aluminum that thin under pretty heavy loads (just to take a guess 10psi of vacuum * 8x4in^2 = 320lbs, easily) is destined to fail unless it's braced properly. The larger the pieces, the more force, the more likely it will be to fail. Not "lulz thats a fail" but, I would not be suprised if the weld ripped right apart. Manifolds made of thicker material, welded by someone with more skill have split right down the seam. At my skill level I wouldn't even try to get away with anything thinner than .125", just not worth the risk of having to do it again for me. I don't know what professional manifolds are, but they are definitely thicker than .032. |
Looks good for the 1st, but yeah, just don't be surprised if it goes boom when you pressure test it!

Its not going on a car. I have one on my Busa that makes 420HP at the wheel and its made from 24ga no problems
|
welds could be cleaner but looks ok
|
Oooooo a turbo busa any pics?
