You engineers and your fancy maths..
Well, that is the total load (Pressure * Area), but the span is what really matters for bending on a thin sheet. A point load would be worse, but so much worse that it would go right through the sheet. Adding in some 1/2" round rod will work like a champ. If you lay a nice bead on it and polish the ends of the rod before welding, I'd think it'd look really nice.
Roger that. I was actually considering using some 1" tubing I have but I think the 1/2" solid will look better. I will chamfer the hole and the rod so it shouldn't protrude a lot and look nice without blending it.
Thanks for looking out guys. I was thinking too that if the manifold lets go, then it will be effectively like having the throttle stuck open naturally aspirated...
Sweet!
^^^That was quick!!!!
I think this thread should remind us how strong the oem manifolds are.. lol. Im running a 25yr old m50 manifold at 30++ psi...

Some small things happend... Got a tiny little milling machine some time ago.
Some small milling work...
BMW 320d Touring e91 -06 ----- BMW 740iA "ALPINA" e38 -00
Audi UrS4 Avant 2.2T Twincharged @624hp/737Nm -93 ----- Audi 80q B4 2.2T @500hp/620Nm -92
What exactly did that accomplish aside from adding a bunch of material and making the top flat? Is there a functional purpose?

How do you easily add oil to the engine now?
I think I like the stock VC better aesthetically...
Oil going in thru the orrange cap you can see in the pic.
I was first only going to re-locate the breather outlet, but then I accidentally got mad with the TIG. And orginal cover looks ok, but I have plenty of them on the shelf if get bored with this.

Hopefully the pictures came through. i picked up a lincoln square wave with tank and all for 600 bucks. After playing with electrodes, collets, lenses, I finally got to a point I could weld this 1.8mm intercooler plumbing. Im getting better at feeding filler by hand and you can probably see I definately bought a polishing wheel. I bought a 3d printer pen for 1.8 filament. It will feed about 5 mm per second for as long as I hold the button and the feed speed is variable. Maybe its just a toy but damn I like pushing buttons. Im not steady handed yet. Its been 20 years since I did any real welding but I'll probably relax as time goes on. By the way that printer pen was 25 bucks all in. Hopefully it will help me to be more consistent and I wont have to grind and polish as much. Aluminum is a pain until you get the right combination of variables. 2% lanthanated seem to be the best combo at about 60 amps to light it off and back it down to maybe 30 or 40 after you get a pool going.
Square wave 200 is nice unit. Not much I don't like except the amount of gas you go through. You should setup some solenoid to lock the gas flow after X seconds. Or make sure you have multiple tanks handy, this was my solution.

My favorite tip for aluminum is to use stainless instead lol.
This is the first aluminum I've done in two years that I can remember. My pedal is broken so I have to use fixed amperage with a finger switch which makes aluminum quite interesting. You have to control penetration with speed and when things get too hot you just have to stop and let it stabilize. Also I'm pretty sure the alloy in the oil pan is 70% aluminum and 30% dirt.

I seem to remember steel being much easier. Im trying to avoid it so I dont come to my senses and throw the aluminum away.
Beautiful welds. When I first fired this tig machine up I had a hard time not destroying aluminum plate. The more seat time I get the better I get but I think ultimately that is what you are getting at.
1.8 to 1.8 is pretty easy with an .040 lanthanated. But if you have allot of metal dissipating or absorbing allot of heat the .040 just cant take the current to start a pool.
I played with the 3d pen. It sucked. Kept shutting off while I was carrying an arc. I pulled the heater out of it and put a 500 ohm resistor in to fake out the thermistor. Seems to feed really well now.
Tip for aluminum is turn it up. I weld all aluminum 30% hotter than I want to. Go hard on the pedal at first and back off after the puddle. Have filler ready and move at the pace of the metal.
