blew my magnus manifold in 2 pieces... why??

[larsrya8]

That's why you should never ignore the "Danger to Manifold!" warnings.

 

[GSTeclipse]

Maybe you missed it but As I already said the New Style Magnus has bracing to stop this from happening.

I might have ....When did Magnus Start this ?

Alot of their's (Magnus) SMIM I have seen bust around the welds and also split down the runner's they have not just blown apart like this 1 that is pictured .

Did Magnus start running a assembly becuase they could not keep up with their order's and just started rushing to get them out the door .

I am not saying Magnus in junk by any means but seems like their craftmenship in work was going down hill !

Hope they did change the setup

 

[GSTeclipse]

This is the 7th magnus I have seen pictures of, blown up at the welds... hehe my JMF has been holding 31psi Just fine

Thats right got to love it huh

 

[CanadianTSi]

My magnus that I got in January has the Bracing so they msut have started sometime before then...

Damn glad I never bought one of those would have been a waste of time .......This has to be probably the 10th one that has come apart by magnus that I have seen on this forums and other's and 2 in person !

Tell them you want your $$ back and go get a JM Fab SMIM

jesus, some people are retarded.

blowing a manifold like that has nothing to do with the quality of the welds or the strength. a backfire will blow the most reinforced manifold with the greatest welds in the world just the same.

track down the reason for the backfire before continuing.

 

[ISUJakey]

Take it to a welding shop and re weld it. Sucks that it happened but not much you can do about it.

Call Marco first.

 

[eldiabloz13]

fix the welds. bead and double bead. make sure its right on when doing so. A crappy weld could do it but so could a crap load of pressure. If its a good weld it will not break at where it was welded....other parts would and should break first. IT SHOULD break at the body if welded properly. Take it to someone who knows what there doing. Its like carpentry....take a chair and use a biscuit to bond the chair together with some glue, and break that chair.....if done properly it will break at the arm of the chair not the bonded parts. And no not the kind you eat biscuits .

That is not correct. I already explained it once in this thread. This is aluminum, it doesn't have the same properties as steel, it is much weaker when it is welded.

[zross1]

If you had a really bad backfire, that's the cause of the problem. It probably would of happened with any sheetmetal manifod

However, I have my magnus off for the 4th time because of cracking around the welds of the runners. Maybe I have the last one made on a friday at 5:00, but this thing is junk. One or two cracks may be reasonable, but not 4. I do have to say, that when it is working I do love it.

 

[Pube Stache]

that will never happen to this manny is build like tank

Ok.. What does that manifold weigh?

 

[1gnasty]

not much is about the same as the stock one and pleaase dont tell me that u are traying to save weigth by changing the in take manny

 

[BrokenTsi]

that intake manifold isnt welded in/out. So im not sure why its built like such a tank vs. other manifolds..

 

[Boosted98gsx]

Ok.. What does that manifold weigh?

Who gives a crap? A 20lb intake manifold that PERFORMS properly is going to be a better investment than a 5 lb that is going to crack and explode on you. PERIOD.

that intake manifold isnt welded in/out. So im not sure why its built like such a tank vs. other manifolds..

Please show me another intake manifold that is completely welded on the inside as well as on the out, then show me the tig that can reach ~18" inside a manifold to do so. Point being, you do not need to weld both the inside as well as the out as long as you get good penetration of the metal and fuse the peices together properly. A properly welded anything is no longer seperate peices of metal, it is 1 peice as you are melting them together. Magnus simply did not use enough heat on his welds, so the penetration and fusion of the metals wasn't there, that is why they broke.

 

[BrokenTsi]

manifolds dont blow apart because not enough heat it used. They blow apart because of back fires etc. Its not like the manifold just fell apart, something serious was obviously the culprit. To say the driven manifold is better, and wont crack with no tests, and almost none on on the market.... Im not saying every manifold is welded in and out, im saying there is no difference between that an the magnus that would make it better quality.

Funny how only the magnus manifolds are blowing apart then ....So your going to say the car's only equipted with a Magnus SMIM that back fires will blow apart ......straight Bull shit

How come JM fabs , AMS , BJ's , Buschur , VRP , extreme SMIM are not blowing apart ? Let me guess they haven't been threw a back fire yet right ? But I am sure they have been threw several backfires and they seem to be holding very well

oh and by the way it does have alot to do with the quality of the welds .....seems like you should know that

 

[RedTurboEclipse]

Those magnus ebay clone IMs are pretty much close to the real one then? =x

 

[Boosted98gsx]

I happen to run one of the "ebay clone" magnus knock-offs. Rather than Al it's made of steel. Gotta say I love the strength of the thing.

 

[1gnasty]

just look ate the sized and the thicknes of the aliminum and is properly welded not like that magnus that blew apart
and yes that is a welding mistake not only a back fire and there is a few on the market only because people is to cheap to buy them even after there was
pruve of the mani making verry good # on the dyno

 

[vr4play]

This stuff works good. I used it to repair an intercooler inlet and some other things.

[desolateboosted]

I have to add to this thread by saying my magnus intake manifold has cracked many times also by the welds at the same spot 4 times.

 

[BluemeanieTSi]

looks to me like you had an injector leak (stuck open) and it puddled in the intake, the fact it blew the filter off should clue some of you into there being a PROBLEM WITH THE CAR and not a PROBLEM WITH THE MANIFOLD. who cares if the welds have blown apart i guess people should start making their shit better so what jackasses cause other problems with poor tuning it'll save them.

"my wiseco's melted when i went lean, that's simply not tolerable they need to step their shit up and make better pistons"

 

[DSMJim]

Dude you blew the welds on your intake manifold, how Fast and Furious!

Your problem is not the magnus mani, and will not be solved with that abortion shown above. The best welds in the world will not stop a manifold from blowing appart when you have a back fire. Cast OEM manifolds blow up into pieces when that happens.

Have any of you guys ever worked on a fast car before? I see a lot of people in here talking out their ass who know dick squat about anything. Not enough heat used, blah blah. shut up. You don't make intake manifolds and you obviously don't weld after what you just said so you should shut the hell up and sit down now please.

EDIT:
Rock on. I was linked to this thread some five hours after saying the same thing to people on another board who referred to a post on "T00nerz." (Don't worry. It's a lame board. ) Glad to know I was right on. The issue is not the quality of the manifold, but what caused it to pop. Even on those manifolds which have cracked in the past on whomever, they likely did not pop like that. That has nasty, tuning surprise casserole written all over it if you ask me.

THANK YOU!! finally some knowledge in here.
