Has anyone tried this intake manifold?

If welds are cracking they werent welded properly, either surface welds or contaminated. A good weld is actually stronger then the base metal.

not true. not only is the weld weaker, the heat weakens the parent alloy as well.

 

[Archer Fabrications]

Ita not weaker at all if you are using the proper filler, the only weak area is the HAZ AROUND the weld, not the weld itself. Has to do with the grain structure transition.

 

[untouchablecc]

Hmm this is interesting. I would like to see how one performs as well. It kinda sucks cause things like this come up and undercut the name brand companys but hey thats free competition I guess.

 

[boost97gst]

It looks good and if it holds pressure and the flanges are true then it would at least out perform a stock IM. Thats good enough for 99% of us who dont want to spend upwards of 1k on a mani. A stock IM, ive heard, has done 600whp. IIRC it was a 2g EDIT: several stock 2g and 1g intake manis have passed 600whp just fyi*. If this is as good as stock its worth the cash.

This would make the bay look pretty at a reasonable price. Im all for competition in the market, thats why things get better.

 

[1997_GSX]

I wonder how thick the material is

 

[Archer Fabrications]

Well hows it working out? Did the install go fine? Allflanges true and flat? At this point anything is better than 2g IM

 

[Spanky_DSM]

Updates?

 

[mchustle]

Easy was easy and very straight forward like any other intake mani with the exception of it the throttle body sitting a little lower and the angle is a little different but still fit fine with my pr fmic pipes. I didn't straight edge the flanges but it doesn't leak with a standard fel pro gasket so I think they are fine. Over all I would say I am happy with everything and it seems like an improvement over the stock mani but I've never had the stock evo 3 mani so I can't compare that although this is not much more than a stock evo 3 so for function and looks I would say it is a good investment.

I have that same manifold and its going on my Datsun. Its pretty good build quality if you ask me. Let us know how it performs.

Looks good, i'm not seeing one offered for a 6-bolt head thou. and where does the MAP sensor go?

He's running speed density. He can put the map sensor anywhere he wants.

This can be true for steel, however the way aluminum gains and looses strength is much different than steel.

After welding 6061-_ heat treatments revert back to 6061-0 which is significantly less strong than the base materials. If the whole thing hasn't been re-heat treated then you'll only get some age hardening, but not the full T heat treatment

You can tell that the welds were weak in the old Magnus manifolds because it split along the weld. I think it is reasonable to assume that if this manifold used a heat treated alloy for construction, they didn't re-apply the heat treatment after welding.

Aluminum can actually age harden at room temperature. Depending on the weld it can take weeks to months of room temp hardening to reach the maximum strength of welded heat treatment, which again is not as strong as a normal heat treatment.

I'm not saying this thing will break. Just saying, if it does, it probably won't be enough to simply re-weld it since that's what caused it to break in the first place ^_^ It would be bad to go through the expensive pop-weld-pop cycle that some have gone through with SMIMs.


It looks like a nice piece. Get some high boost into it and let us know how it goes!

i wasn't asking where his was. if your not running speed density, than you can't run this intake? just asking.

If you're adding a MAP sensor to a vehicle for any reason then all you need is a vacuum line connection somewhere behind the throttle.

If you're actually referring to the stock Manifold Differential Pressure sensor and not a MAP sensor (4G63s did not have a MAP sensor from the factory) then yes, you're SOL if for some strange reason you actually want to keep it. The MDP sensor is used by the ECU only to check for the proper operation of the EGR system.

That's because its not a dsm manifold.

Actually the NT's did

N/ts are Chrysler engines so that's obvious.

 

[Archer Fabrications]

I wanna know how this thing performs.

same here. It's either this or magnus street for me. Though I may give Magnus some support just because. Marco or David.

Good luck using this manifold on one of those.

Went ahead and changed that word in my post since it wasn't 100% though.

 

[marck_c]

Would love to see how I performs. What does it weigh?

 

[Archer Fabrications]

Were never gonna know what this manifold performs like, op bought it off ebay and buying no name performance parts in general from that "vendor" alone screams "im not serious about performance" member since 2009 and not a single track/dyno run??

Most people serious about performance would choose something tried and true, rarely do we have people like ted that come up as a dsm ginny pig which actually go fast and go to the track.

We wont get dyno numbers, or track results... Back to back over stock Ever.

/thread.

Unless someone else bought it and has feedback. I know i personally wouldnt risk it.. But it does *LOOK* like a nice piece, but so do other ebay manifolds that have a proven track record of being garbage.

 

[donniekak]

A guy with a holset on his Dsm talking about tried and true, and guinea pigs, . I remember when the word holset first appeared on this site. I guess they should have stuck to the tried and true, and not been guinea pigs for an untested diesel turbo.

 

[Archer Fabrications]

It is tried and true now. Ever heard of talon dave? 9.2 1/4 mile holset?

You should re read my post, i said there aren't many ginny pigs anymore (ginny pigs are a good thing to have on your platform), and op has never seem a dyno ir track, or even posted logs.

By the way, i said MOST people would go with something tried and true, not all.
(Im running parts i fabricated myself and they are in no way tested/proven. Holding up great so far though.)

Thanks for bringing up a holset vs "proven turbos" in this thread...
Troll.

Not saying this manifold is good or bad, just saying no one is going to test it. And no one has.

The manufacturing company/individual obviously doesnt care about the numbers either.

Exactly. Just like people had to try holsets to get them to tried and true status, people need to try different parts from time to time to find the next proven combo. Thanks for proving my point for me.
