True the Magnus made an additional 10+whp over the previous highest flowing IM tested, but I feel it's highly negated when considering how much it lost in the midrange. If the losses in the midrange on the graph you overlayed was compared to the V2 IM, that just means it's worse when compared to a ported stocker. This manifold is great for top end drag cars keeping the revs above 7k, but on a street application where a lot of races start in the 4k-4500krpm range this manifold will exacerbate that midrange weakness of a large turbo Evo..even with brake boosting. You will need one hell of a top end to make up lost ground when taking on high power, high tq V8/10's on a closed/private road of course.

I really hope you can come up with a great Intake Manifold that'll produce about the same high rev power as this manifold but yield a much better midrange...my money's on you'll succeed with that production Dave!

Thanks again for all the testing, you're just helping us develop even more lethal Evo's out here.

 

Nissan3EVO, I appreciate your input and thoughts on the intake manifolds and testing. The baseline run was against the intake manifold we built which has had the best low/mid range of any aftermarket intake we have tested, about 10 whp in the low/mid from the stock ported intake.

With the amount of stress and hate that my last round of testing produced I would appreciate it if everyone stays really polite and politically correct on this round of testing.

Marco flat out told me the design of this intake is for 1,000 whp and 10,000 rpm, it was designed to produce power for drag racing applications. Pointing it out from any of us over and over just seems to insult the product and it is a good product and does exactly what he designed it to do.

omg, someone pull up weather.com and check and see if hell is freezing over!

Good test. Keep'em coming dave, its much appreciated.

 

As you well know, its always the combination of parts that makes for a great result

It looks like the Magnus intake is a very high flowing - in fact highest flow intake it would be well suited to a car set up to take advantage of the power band of the intake

There is no such thing as an "ideal" intake manifold

It is a fact that a intake which maximizes low end power through inhanced velocity of air flow will loose top end power and visa versa


As we have all seen in the last year and a half often the highest whp set up is not necessarily the quickest on the street

I beleive the key to success in life is having the additude that you can always learn something new no matter how much you already learn

You have exemplified that additude over the years

The best part of this business for me is that every day I learn something new

On our STI's that I have been working on the Magnus Subaru intake has been a really great product

While I did not care for the old sheet metal Magnus Evo intake - I did use it to be the first to go 9's without NOS and the first to go 9's on a Gt35 Evo - 5 years ago - so it was hardly a weak intake IMHO

I feel the cast new Magus took a huge step forward and is an amazingly good value for the money

The fact that the price point is so good and its the best flowing intake on the market are two great factors

I dont care who is making it a cast intake is always going to last longer and be more reliable than a sheet metal unit

I have seen so many sheet metal intakes from all different manufacturers that cracked over time, on a street driven car I always prefer a cast intake for reliability

Those who do a lot of no lift shifting and two step will also like a cast manifold

Great thread Dave,very informative.

 

Well we got most of our parts for this new idea I have today. I have to admit it is the ugliest piece of crap I have ever seen. I almost threw the entire abortion in the garbage as there is no way I would run it or sell it BUT in the quest for more knowledge I am going to finish it and build it with the adjustable runners and see what happens. It looks like a mini-mail box, it is SO ugly.

 

Pics of this vomit-enducing bastard child!

 

Just make sure you put a little red flag on the side of it!

 

Let me get it finished then I might post pics. It is pretty disgusting. It looked good on paper, in reality, wow is it ugly. It will be good for testing but beyond that it's to ugly to use. It needs a red flag to flag it alright, warn you not to look at it! haha

 

lets get these new ones finished! lol

 

Nice turn of events. The new one, now that it is welded up, looks pretty good actually. Should start installing it tomorrow and putting on the rest of the brackets and mounts.

 

sweet, cant wait!
