john shep uses the BJ's sheetmetal intake, hes doing pretty good id have to say
and the magnus is 1 of the better for street drivability. very to no low end is lost in many cases.

I dont get it why is every body bad mouthing other shops and products.?? I can understand that some ppl have issues with the quality of some shop's products. So if that is the case just state it and give a word of caution to others. We are the consumers we dont give each other crap, and lies trying to sell stuff that we obviuosly would never see a penny for, this my fellow members is called word of mouth uncut and totally real. 
If they don't like it, then a review is a bash, yes? I don't like it, Im not bashing it, simply reviewing all the reasons I don't like it.

im telling you it sucks, and why it sucks. i dont care if someone wants a 9 sec car or a 14sec car, either way the manifold is not worth the money. not like its going to perform better on either. For a little more you can have a NICE manifold, thats PROVEN power. Not saying people cant or shouldnt buy it, thats theyre own choice, but i suggest looking elsewhere.

Flow distribution between cylinders. Marco didn't design his intake overnight.
What's important is what you want the car to do. If you like good response for the street don't go with a manifold that has a large plenum. It makes for crappy transient response. I've driven a car with a venom manifold (new style) and wasn't impressed for real street driving. Sure it pulled hard as all hell at high rpms at WOT, but it just wasn't as fun to drive on the street. The owner of that car has since gone back to a stock intake manifold and still pulls high 11s on pump gas.

That seems more like a turbo problem than a Intake manifold design flaw.

I know two people with the bj's manifold and neither one of them complained about lag.
Why do people who have never had a part on their car talk about it like they know something.
You would probably say a 50 trim was laggy too.
Give me a break...

those manifolds being? because ive seen a post, a dsm club forum ill look, said dejon intake manifold added 11whp. swapped it for the BJ and gained 27whp no other tuning. the dejon manifold wasnt carefully tested and designed. basically it looks like he sketched up one, made it, and sold it. wether someone thinks its good or not, its overpriced for using MILD STEEL, and looks poorly crafted. the the flanges like his other things look on the thin side. people have much different tolerances of lag, many say the 50trim is laggy, they in my opinion are on CRACK.
but by all means u run mid 11's, obviously you knw what the best intake manifold is. you guys can bench race between these damn manifolds and use the butt dyno to decide, but PROOF is the real deciding factor between these all. and magnus's 54whp gain is pretty impressive.
and BTW the magnus design manifold was good enough for 650whp so far, so i dont see a problem with it.

...Damn near all, if not most of the dsm's out there have at least one part from dejon (guess this means they all buy crappy parts also).

dejon's manifold...yes (might not have the looks as some but it does exactly what Dave said it would) Also Dave tells you when you call about this manifold that he made it as an idea. Aren't most of the products we buy ideas (Case and point maft)? Not once when you call and ask Dave about this manifold soes he say it will give you X. The only thing he has stated is it's better then the stocker.

so you dropped 2 seconds by just installing a dejon intake mani, and not touching ANYTHING else? and the reason people are naming theyre problems with dejon, is to show how great this manifold probly is. ive heard at least 1 complaint about every product he sells, so this may or may NOT be different. Dejon mani is yet to be proven, and it wont be able to hang with most of the other name brand manifolds i can tell you right now. and his manifold is far from 'cheap'. its 400$ (only 100$ less than the proven and bling magnus) and it looks cheap, no testing involved in the design, and its cheap mild steel. powdercoat scratches off that thing itll rust real quick.

To answer your question my car and again it's my opinion so before this goes the wrong way let me explain. When I said proven I was talking about my times at the track from last year to last sunday with his manifold on. 13.9 to 11.9 (yes this w/slicks was the only upgrade). To "ME" this is proven but since this is not enough I'll get to the dyno and post the #'s. After reading all the pages it seems the only thing this thread has turned into is how much everyone has had a problem with dejon. I mean correct if I'm wrong but wasn't it started about a new product that has come out?
