David, I could have saved you a lot of pissing and worry. I've NEVER known you to lie. There are those of us who take advantage of hearing you say things ONCE, not twice. Excellent effort and a good back up to your previous tests.
Now that you've done it again, I guess that means that the price of stock manifolds is going up.

 

Thanks for sharing the result here!

BTW Have you tested this one yet?(Im a little confused is the result in post#88?)

 

I'm still curious why others have found gains with the Magnus. I'm not trying to add drama, I am genuinely curious. WOT demonstrated gains with a Weapon-R, albeit on a smaller turbo (with a 65mm throttle body). Typically, in the results I've seen, boost drops with an aftermarket intake Weapn r/Magnus style manifold indicating the engine is breathing better. I have a newer Magnus sitting in my garage, and I am expecting it to make power...just like I have seen from two people whom I trust from SoCal.

I don't understand the conflicting results. Is it the much bigger turbo? (the testing I've seen was on a Green) Dave's was on a much bigger set-up. Does anyone have a suggestion? Do velocity stacks make that big a difference? What could it be? Thanks.

 

So anybody wanna buy a Magnus intake? Give ya a great price!

Chris

 

Too many crybabies

 

^ wow, that power compare doesnt look so good. since there are several magnus intsake variants, can you have someone post a pic of the actual magnus manifold tested?

Test on!

edit: after seeing the power run video, that magnus unit has a very small plenum area around cyl 2 & especially cyl 1...maybe its just the video angle?

hows that ams unit?

 

it looks like the magnus got really rich - not flowing enough air?

 

If you want to talk about maxxing out a part, tuning for a part, etc, etc......ok, I'm game.

Lets look at the boost curves, ok they are the same minus the Magnus test spooling up a little slower.

Lets look at the air/fuel curves.....they are different....looks to be about a half a point difference at 5000RPM. You don't have to be a genius to figure out that half an air fuel point isn't going to give you 40lb-ft of torque.

Now why is the air/fuel curve so much richer on the Magnus test?? Well, the AEM EMS is a MAP based system, so its only use boost pressure to determine load. We know that boost pressure is the same between the two runs, so that only means one thing....the Magnus manifold is flowing less air at the same boost pressure, which will cause the air/fuel ratio to go rich. Less air means less power and that's what was shown on the dyno today.

 

And this runs contrary to other's results, which is why I asked for an explanation regarding the discrepancy.

 

well it sounds like David did the test properly...not sure about the others.

 

If the price is free and I can blow it up via my ar-15, sure.

 

05-EVO-GSR, David said he did not want to post the Dyno chart...So why would you post it in his Intake Manifold testing thread? I just don't get the members around here sometimes. The guy is doing us a favor and you just totally go against his wishes!?!

 

+ Eleventy Billion

That asshat...

 

Is the day over yet? Really want to see the VSR results. It's a great service you're doing for all the evo freaks, thanks Dave. Oh, and ifarted2 also.

 

I don't care if you guys cut and paste the results. I said that I personally do not want to do it. I am done with it. I proved my point, for the third time actually on this same product, I am done with it now. There will be the doubters still but I just can't deal with that mentality.

This intake is of his old original design. It does not use a velocity stack with a radius on the inlet. It is basically a piece of straight pipe with a little flair on the end that extends into a heavily tapered plenum. on the #1 runner the distance from this tube to the back of the plenum is maybe an 1.5". Back in the day it looked good, the new intakes out now like AMS's, Hypertune make this look like garbage to be honest. I built probably the first sheetmetal intake for the DSM's long ago. I used no velocity stacks, just a simple 4" round plenum, I never tested it, it is crude compared to today's stuff too but I think it would still work better than this design.

I have a serious problem with most people's dyno results. Most people do not try to keep the runs consistent, same day, same dyno same parameters. Just think about it for a minute. The average guy who buys a part spends his hard earned money on it and puts it on. HE WANTS IT TO WORK, he just spent his money on it. MANY and I mean MANY of these situations end up with more boost, more timing, leaner AFR's to get the power up with their new part. They also many times had more than just one part added between dyno testing. For example maybe an intake AND a 75 mm throttle body along with some new I/C pipes to match up nicely. That is not a test of ONE part that is a test of multiple parts.

This is the THIRD time I have dyno'd this particular intake manifold. Once on the stock turbo, once on a normal 35r and now with my HTA35r. Each and everyone of these tests were done back to back, same day, same dyno with NO change other than an intake manifold. Each and evertime the results were the same as this one. Actually that is not true, from memory the last two times I did the test I don't recall them losing 17 whp up top like this one did, it was less but STILL a loss the entire range. Each time there was a 35 whp/35 ft lb loss in the midrange just like this time.

Marco (Magnus) said he has re-designed his intake manifolds. He has real velocity stacks in them now and has a street and race version. Will his new ones make power? I have no idea, I am not going to speculate and quite honestly I couldn't give a flying **** if they do or don't. I would not test them for any amount of money, drugs or sex

ifarted is doing some testing, he has the new styles.

Have a good day.
