1G The importance of boost leak testing....

[SasaniFab]

Sooo since purchasing my new tig ive been welding and fooling around in the garage. I built a new a new set of aluminum charge piping and wasnt completely satisfied so I built another set of stainless charge pipes. In the process i built a way to test for leaks as I welded. Testing every pipe beforehand before I bolted it to the car. What I found I shocked me. Welds that were tested on the car which didnt leak at 20 psi , leaked at 30 psi....long story short the car was dynoed with several large boost leaks. Now that every weld is air tight the car idles better and my afrs are much more conistent. Some are gunna say.... no shit right. I can imagine most guys havent pressure tested their setups to 50psi.I find pressure testing on the car to be a pain in the ass as part of the weld is usually hidden or stuffed behind something. Either way im just happy to finally have my system to be air tight. I also took the opportunity to weld in a npt fitting for my meth injection. I was using a devils own adapter that tends to leak. Little off topic -Im Also working on making a new top mount manifold that will use a custom hood exit. I plan on incorporating the wastegate in. Havent decided how yet. This is not the correct section for that.

nice welding ...(not archer yet but more than competent good job !!

Im practicing as much as i can....i really enjoy welding. Gotta start somewere.

Im finding that lower amps and smaller filler is best for stainless. Controlling heat is key...Purging is also not an option imo, do is correctly or dont do it at all. As far as aluminum I find that higher amps and bigger filler and good pedal control is the best for aluminum.

Now practice me a twin scroll mani j/k... lookin good

Its funny, when u are a noob welder you are happy to melt two pieces of steel together. When you start getting proficient you spend so much more time making sure the welds are aesthetically pleasing. Stainless is very very heat sensitive, using a gas lens with a large cup makes all the difference if you want that rainbow effect.Ill get right on making you that manifold

 

[SasaniFab]

Redid my dump piping as it wasnt welded correctly and was leaking ie purged....

 

[SasaniFab]

You guys were right.... green tungsten rocks with al

 

[SasaniFab]

Yup

 

[SasaniFab]

Just messing around

Boost leak tester... homemade

 

[boostdawd]

Awesome stuff. Keep an coming.

 

[SasaniFab]

Im completely terrified when using my boost leak tester. I have to say blowing a coupler off at 50 psi when your holding it.... good way to empty uour anus

Boy you got that right, mine blew off at 38 lbs and dented the UICP and scared the holy jesus out of me, and could have seriously hurt someone. I had it tbolt clamped on so how are you holding yours on at 50?....well or 49

Nothing wrong with taking pride in your craftsmanship and doing it till you get it the way you like it. Also really considering welding classes

On the car, its holding fine because everything is so compact. So i designed it like this.... after dropping a deuce in my pants when it exploded into my nutsack i took 4 bolts and put them in a jig that I have for safety wiring. I drilled the holes in the heads and cut the heads off and welded them to the side and top of the pipes. This way I can run safety wire through and tighten them down. Ive noticed that what tends to happen is at elevated pressures once it starts to slide, it cant be stopped...almost like momentum. Its working perfectly

Love the fupa 12 cup....

 

[boostdawd]

Would u weld on the side. I got some stuff needing some welding. Keep up the great job.

Pm me the details

Glad to see you use a jig when welding on flanges. You look like you are catching on real good. I only have a 110 flux core for now but would love to have a multi-purpose welder (aluminum, stainless, regular stuff).
Looking good man, looking good!

Thanks man, i made two jigs, drilled a hole half way through and out the side so i can run argon through. Aluminum soaks heat up so well.....keeps the flanges flat and keeps the stainless stainless. My longevity came with a trigger switch on the torch so i got used to not using a new pedal. Now that Im used to a pedal I love it... the minute you overheat the stainless you loose that coloration and stainless properties..... I really want the miller dynasty 210d.....

It's just pocket change.....

 

[joemamma]

i love my lincoln 200 square wave tig

 

[SasaniFab]

Im not gunna lie...... harbor freight is coming up. Ac balance and pulse controls ....Not bad for a starter
