Mangus Intake Manifold, Good or Not??

now back on topic.......
if you do get a sheet metal, i'm sure you plan on getting cams, right? if you haven't already.

Agreed, if that's what your goal is, a SMIM is not going to help you in that department. SMIM's are for maximum power at maximum boost at maximum rpm's. If you dont mind giving up some low rpm spool, for more power up top, it's definatly a good idea. Just depends on how far you plan on taking your car mod wise. From what it sounds like I think a Buschur ported manifold would work better for you.
The Magnus piece is top quality, it was the standard on all the fastest Evo's for a while. However it seems that the AMS piece has since taken the throne as the best SMIM on the market for the Evo.

Mine was made in 2003 and was one of the first prototype after I sent my stock intake to Marco. THis was way before any other intake manifolds were even made in the market.
I wouldn't say its the best but the design is fine and it does what its suppose to. I have seen significant gains in the earlier DSM motor though.

We've gone through 4 design revisions since then. Yours was the very first, and AMS's was the very second. I designed this intake manifold back when RESPONSE and TOP END power were key. Most people report no loss of bottom end power and 30whp increase with the magnus intake manifold, the secret is the properly sized and shape plenum that everyone and their sister thas tried to duplicate.
It has worked and still works to this day propelling many cars into the 9's
if you want a testimonial on the product look here one of the moderators of this forum posted this https://www.evolutionm.net/forums/sh...ghlight=magnus
Now for 2007 there is a new design, for those less concerned with response, and more into Drag racing. I'll give you guys a sneak peak. This is a 1G DSM version with extra injector rail flanged for Q45.

AMS did well, too, using their manifold on their Evo with alittle slower ETs but higher MPH. So, I'd have to say that either would give a significant performance advantage over stock.The new Magnus looks very nice. Magnus also has a race manifold on their webpage that feeds all cylinders simultaneously. http://www.magnusmotorsports.com/int...ifolds/dsm.htm That's an awesome piece of work, if your motor spends time above 8000 RPM with regularity
I'm probably not the only one who is curious as to the calculated resonant rpm value for each of the most respected manifolds (Magnus, AMS, Full-Race, etc.), as well as the factory piece. This information would provide material for a good discussion.

Sales, however, do not equate to being the "best" in performance, and I am not aware of any intake manifold testing that would suggest that the AMS has a performance advantange over the Magnus (or the other way around, for that matter). Marco Passante (Magnus owner) won the Quick 16 class at the Buschur DSM/Evo Shootout this year running 8.73 at 160 MPH. I bet he was using a Magnus manifold. AMS did well, too, using their manifold on their Evo with alittle slower ETs but higher MPH. So, I'd have to say that either would give a significant performance advantage over stock.

(edit)
The Magnus intake you linked looks promising it seems some of the newer designs as well as the higher price ones (HKS, Jun etc) seem to have the TB angled as the air enters the plenum. Does anyone know what advantage this would serve?
On another note, the Full Race mani (which also has the angled TB) looks VERY nice, and from the pictures I've seen the TB looks to be a spectacular design. It will be very interesting to see how it compares to Magnus or AMS here shortly.

Have seen the latest revision though...it has newer added features that mine doesn't have but works extemely well...
When I mentioned DSM motor, somebody here actually picked up 30 WHP at the top when they switched to your manifold...
I have the AMS VSR and like it a lot. On the stock turbo, I picked up about 15 awhp on 26 psi and meth. I have their 50 trim now and from what I've seen on evos with similiar mods, on my pump gas tune, straight 93 octane, I put down about 20 awhp more than them on the ame dyno. I did lost about 200 rpm of spool on the turbo, but don't even notice it.
It does seem like a lot of the big names (Buschur, Dynoflash) use the AMS VSR over magnus now. There must be a reason why. I have a friend who had the magnus one on his 2g and had cracking problems. I haven't hearn that from anyone with an AMS VSR. I guess time will tell. It would be nice to see a test on all the manifolds out there like HKS, Jun, AMS, Magnus, etc.
