When speeking about a sheetmetal intake manifold the discusions and arguments could go on for days but, Why is it that marco's (magnus) design works best? And why is it still the most populare manifold around?
The answere and ultimately the key to all manifolds is lag . mngsx touched on it be 4 . See when air is being introduced to the manifold the bigger that manifold is the more space it has to travel thus sacrificing driveability and increasing lag. If you study marco's design it tappers down closer to the last runner . Are you seeing the picture??
As the air pulses in, the first runner would obviously suck in more air , and in turn tappers off until the last runner . Well marco's design forces the air inside to circulate thus being able to supply each runner equally.
Ok let me better explain as the mount of air decreases further down the manifold , the less space there is to hold it in transit.
We all know that the fireing sequence for the runners is different so different runners sucking in different air at different times right . but the way the the air is deliverd to those runners is what makes the difference.
I personally think that marco's design is simply the most efective , most other companies would rather just copy each other's design and changing little charachteristics around to distinguish themselves for the customers.
Once their was a man who copied marco's design and made it out of cast iron , well that dident fly with alot of people ,,,two days later no one herd anything more about these cast copies . In the dsm community nobody likes to step on eachother's toes but rather help eachother out, in more ways than one.
I have a magnus sheet metal intake on my car and I love it to death aside from buying an awd talon that was probably the best and easiest choice I ever had to make about reliable horspower.

but I can tell all tomm. after the dyno.
