"4-Tow Hooks - Some think its ricey or a way for a thief to steal it, but they'll do it anyway. Even street/strip guys at the track keep them around in case a golf cart has to tow the car back if trouble occurs."
And how is this relevant here?

Re: Wastegate broke off
Soooooo.. Where did i say Aluminum? or or anything of that caliber? My point is that tow hooks (very quality ones now) are quite available. Don't know about aluminum ones. The only good ones I've seen sold are from Racer's Wholesale or a Grassroots motorsports vendor.

Re: Wastegate broke off
The weld joints and surrounding areas are usually weak spots. These are the first areas to go (from rust, strain, etc.) due to either the material being thinner at the weld joint or the surrounding metal, or other inherent flaws introduced (bad welding, etc). I'm not a welder but I'm sure someone here can add more info if needed. It's likely the strain caused the weld joints to give. Now wether the weld joints were subpar and were the cause I have no answer...
The flex/torque idea is similar to why flex pipe or springs bolts are used on a header as well. You want some flex to avoid cracking when the material reaches it's elastic limit (due to vibration, movement from the engine, etc.).
I would try and find a way to support the downpipe but not in a way that's completely rigid. I honestly don't know the best way to support it but maybe others on here have ideas.
Anyway, let us know how the new manifold is working. I'm curious to see the fixes and some pics of the manifold before it goes on to check out the quality.
Good luck with the new mani!

Re: Wastegate broke off
I was bringing up the point, because usually thats what someone is talking about. I've heard of the cheap ones breaking and cars being destroyed. Lately when someone says tow hook, it means one of those ankle breakers sticking out from under a riced civic. I would never install on of those POSs on my car, mine has good factory tow loops but I need some lower anyway to clear the lip.

"Some think its ricey." - I didn't say that I
thought they were "ricey". I'm using terminology for the context of my sentence.
I told you.. I'm specific with what I write. ..
Boy, turbohatch, you are, if nothing else, entertaining..

YOU POSTED THAT NONSENSE TO BEGIN WITH.
THEN YOU TELL HIM WHAT DOES THE TOW HOOK HAVE TO DO WITH THE THREAD.
YOU POSTED THE NONSENSE TO BEGIN WITH..
WHAT YOU POSTED HAD NOTHING TO DO WITH HIS MANIFOLD CRACKING IN 6 DIFFERENT PLACES 6 MONTHS AGO.
MAYBE I SHOULD TYPE SLOWER OR SOMMAT.

Re: Wastegate broke off
What was the final outcome on getting this fixed? I also posted the high temp snap exhaust grommets, the idea was given to make a hanger bracket, and I had run across these grommets, Jegs want something like 25 bucks for a piece of stainless with one, which is simple to make, but the grommets are cheap enough to use

Re: Wastegate broke off
this is a simple bracket I made for supporting my exhaust tips, just sheared off some steel and rounded the edges on a belt sander, then bent it with a hammer in the vise, something like this would work to support the downpipe off of the firewall

Re: Wastegate broke off
*Update: I don't know how to read FedEx. Showed "Initiated" Friday 5/2/14 and Estimated Delivery date Wed 5/7/14. Now when I tracked it it shows "In Transit" Ship date 5/6/14 Estimated Delivery Date 5/9/14 so I'm assuming that FedEx doesn't update right away. So looks like I will have a manifold on Friday the 9th.

Re: Wastegate broke off
Jeeez I got a headache reading all of this. It's funny how a mention of a phone call from the manufacturer about "handling" the faulty product, had everybody swinging saying how bad *** he was and I'm spending my money with him. But later nothing never happened. Actions speak louder than words, which I'm sure everyone knows, but forgets. I looked at that manifold and its problems and wouldn't touch that. Then this thread goes into a bickering match about nonsense. Moral of story, there are better turbo manifolds than this, and you guys get crazy sometimes, or buzzed...

Re: Wastegate broke off
if you want to make one of those it's so simple, cut your material to width,calculate your height to the center of your hanger, cut the height, use a compass to scribe a circle the radius of the small end of your bracket, scribe lines from the sides of that circle to the bottom edges of the piece, now cut your angles, and use a belt sander to round off the top, drill your mounting holes etc, I used 1/8 cold rolled, so I couldn't bend it in the brake, I just clamped it in the vise and used a hammer for the angle, if it's coming off your fire wall, you wouldn't need the bend. If anything looks like it's stressed, add a hanger or support, better to have too many then not enough,same with gussets. Thats the main thing I see missing, some of those pieces off the manifolds should have had them, they are easy to make, and add a lot of strength, on my hanger isolater, I used baffling material like we use on the airplanes, it's fire proof, I glued circles to the round washer in the middle, and on one side of each outer washer, it's strong, but also can absorb vibration. We use strips of the same material glued together to hang the exhaust pipes off of the airplanes, just like your down pipe

Re: Wastegate broke off
I don't want to start an E fight, but want a couple of serious opinions, it's hard to tell in the pic, but it almost looks like no weld penetration at the flange at all, almost like the welds are just sitting on the surface, I'm not the best welder in the world, but I do know what a good weld is supposed to look like, I'm interested in this thread because I'm trying to figure out what went wrong, from a technical standpoint

Re: Wastegate broke off
It almost looks like it was a fusion pass with little to no filler. either that or the weld el and the flange weren't given a fillet to allow the weld to penetrate properly. it could also be a result of not enough heat, travelling too fast, etc.
the only way to tell how quality and structural the welds are is to run a lighted inspection camera through the manifold to check for signs of penetration or destroying the manifold and cutting each welded joint in half lengthwise to check penetration.
if you don't have a camera go to Lowe's or home depot and bring the manifold. they normally have one of those lighted inspection cameras on a display lol.
this is why I always say give each welded joint a good fillet during fitment so you can be sure the root pass penetrates properly... and backpurge to ensure complete penetration without any sugaring inside the welded joint.

Re: Wastegate broke off
I've been looking at each page deciding which posts to delete... i have my work cutout for me lol. I'll start deleting after dinner, remember if anyone gets a bunch of deleted post PMs remember it isn't personal.
did you post those pics in welding/fab? the lack of penetration bugs me a bit.

Re: Wastegate broke off
one thing I noticed between these, and the way we do the flanges for the aircraft engines, is on our flanges, the holes in the flange are sized to let the pipes fit tightly in the flange, not just on the outside surface, this gives it some additional mechanical strength

Re: Wastegate broke off
I've requested that this tread be removed. Tim and I just had a very intense heated conversation about the situation and it's been put to rest. Both side had valid points and both sides understood. Tim has taken responsibility for his side and has apologized as did I.

Re: Wastegate broke off
well at least let us know what went wrong, obviously something did, I 'm just interested from a technical standpoint, and from the standpoint of someone who does fabrication
