Anyone considering a Magnus manifold, check this out!!!
Holy moly....I saw a N02 explosion do that and bend the butterfly in the TB into a "V", the same time it blew the end tank off the intercooler, and a 4ply silicone coupler in half.
If Marco replaces them, well that is reassuring.
However his absence in a thread like this is dissapointing. Would be good to get the manufacturers take on this.
I run the Magnus Race and it has been good for me up to 2.4 bar. Not many miles on it though. If it breaks, and Marco replaces, well I'm ok with that. Hopefully it will fair well in the mani test ifarted2 is doing.

Sorry, bunch of you guys are not correct.
I've had 3-4 of these intakes break just like this on customers cars. BUT I will say that Marco changed how he was building them and does repair them for free, if it makes you feel any better. Is the intake that blew up old? I don't know that I have heard of any of the newer ones breaking like that but then again I think everyone I knew that was running them have changed because they broke......
I don't believe you had a backfire/misfire, I believe it just failed as I have seen others do.

, The truth is the truth. The older style manifolds can simply fail under high boost alone with no backfire.
I picked up a magnus manifold awhile back, and never installed it because I was concerned it would fail at the welds. I think I'm personally going to hold off and get a different one.

This thread is ridiclous
Anyone who cannot see that that was caused by a Backfire ought to have their head examined.
Methanol injection is usually a poorly designed 300 dollar band aid solution, to trying to run more boost for a given octane. No amount of Methanol mixed with pump fuel will ever have the same power potential as race gas or straight methanol. And no mechanical injection device spraying fuel into the intake manifold like an on off switch will give you proper control. This is why Meth injection is the number on killer of intake manifld over the past few years.
We have pressure tested our intake manifolds to over 130 psi of pressure. We have put them under the most destructive torture tests. But nothing can help you when you have Fuel igniting in the intake manifold. You are basically creating a bomb under the hood of your car.
Most people who have had nitrous backfires, and meth backfires don't have issues like this because they are below 150 psi of pressure. When you get explosions above 250 psi of pressure is when the manifold will no longer hold together. Since I don't know of any evo running 250 psi of boost, we dont need to build a manifold to withstand that.
AS you can see the external brace that is there to help protect against backfires has still held, but unfortunately everything around it has completely pulled apart as well. A huge explosion took place and the stongest parts held together as they were supposed to. You had a very very big explosion happen, enough to push valves open, which then collide with pistons, You may want to check that you did not damage your engine as well.
When you have built as many intake manifolds as we have, and we are talking in the thousands. Subjected them to racers, all things racing, and general overall abuse, an experienced eye can tell you immediately what happened.
To all those other companies out there who say they have never had an sheetmetal intake manifold break, you are either (a) lying, or (b) haven't been doing it long enough.
Our Manifolds have been on more 1000hp, 1400hp, 8 sec and 6 sec cars than anybody elses out there. They have seen 60 psi in Paul's car, over 50 psi in most our customers cars, and 80psi in Brents 6 sec NHRA modified class winning car. After 12 years of this we're still winning races, still winning championships, and going faster and faster with the 4G63 than ever before.
And for the record, I take offence to the name of this thread. It should be called "Anyone Considered how bad tuning, and incompetence blows up parts? Check this out!!"

Marco you alway crack me up
Marco, I have a friend who does failure analysis on these types of things. I'll be more-than happy to see if he'll take a look at it and give an expert opinion of the failure mode.
Here is some good advice for whatever manfild that you are running if you have a high HP car and/or run a sheetmetal manifold with high boost. This $65 piece would have saved all of those blown apart manifolds out there. It basically acts like a relief valve, allowing the excessive pressure to vent to the atmosphere in the event of a backfire and prevent the manifold from blowing apart. I install them on all sheet metal manifolds that I install. IMHO it is a must have item for everyone running nitrous and good insurance for those running high boost alone. you can even add one on each side for added safety
I've seen Shepherd have huge nitrous back fires twice in person. Busted end tanks on intercoolers, bent throttle blades, even ruptured thick HD i/c couplings...........neither of them blew the intake manifolds apart.
I am still curious to the answer to my question, how old is that intake manifold? I am surprised Marco didn't ask unless he already knows. There were quite a few of the EVO intakes in the beginning that blew apart, I thought maybe this was one of the old ones. I know two blew apart on Matt Smith's car and he runs no nitrous or meth. I'm not sure how many Al blew apart, I believe 2 of them also but he does run meth on occasion.
