in the morning?? c'mon DB dont tease us like that!!

 

Woohoo DB is back on the dyno!

 

I was too curious and I couldn't help myself so we ordered the new Magnus V5 intake manifold from Titan Motorsports.

First step was to go to the flow bench.

On the flow bench this intake is in a league of it's own. The numbers were fabulous.

#4-352(-7%), #3-377, #2-377, #1-369(-2)
Total CFM 1475

As I said, league of it's own on air flow. The total CFM is 150 CFM higher than the closest other intake manifold I have tested. As a side note, I did not have a throttle body to bolt to the intake manifold. The JMF I flowed with the supplied 3" throttle body on it. This one I flowed with no throttle body at all.

**Now before I go any further with this. I called Marco at the point I was done flow benching the intake. Him and I spoke, peacefully, for about an hour about everything, past and present. He was very hesitant to speak to me at first and I can understand that. We agreed that neither of us handled last years mess like we should have. It was also agreed I would dyno it and give him a call before posting ANY results from my testing.

The intake is very nice quality, very nice casting. It comes with a nice billet bracket for the throttle cable to mount to. It also has vacuum ports cast into the back side of the intake which makes it nice for hiding all your vacuum lines. There is also a stock throttle body adapter plate that is included with the bolts and nice heat barrier gaskets. The back of the adapter plate for the throttle body is nicely radiused like a velocity stack too.
There is no provision for a dipstick mount, I just had to bend the stock dipstick to fit it and then used a wire tie to hold it down for testing. A bracket of some sort could be made to hold it. Also, if you are using the stock fuel pressure regulator you will have to bend the 90 degree return on the base of the regulator slightly to clear the plenum, it's not a big deal. I am also running PTE injectors and they are a little fat, so I had to clearance the fuel rail stands with a die grinder to get them to fit. Last, I did have to make a new upper section to our i/c pipe to fit correctly because of the slight angle the throttle body sits at on the intake.

Here is a picture of the intake manifold installed on my RS:



After getting the intake on the car it went directly on the dyno. I ran baseline pulls of the car in the morning at 30 psi and 40 psi.

The results were very good. As you can see from the gragh below on low boost from 6000 rpm up the Magnus intake had gains all the way to 8,000 rpm and beyond. Peak gains of 18 whp and 7 ft lbs. Keep in mind this is being tested against the BEST intake I have found so far, not the stock intake/stock throttle body. Against stock parts the gains would be in the 30-50 whp area (estimated).

Here is the low boost dyno runs:



The boost was then turned up to high and the car was run again. Again, very good results. This time the gains started at 6400 rpm and went all the way to 8,000 rpm and beyond again. Peak power was up 10 whp and peak torque dropped slightly by 6 ft lbs but only because the curve was shifted.

Here is the dyno sheet from the high boost pull:



Marco and I spoke again about the final results and he is pleased with the outcome.

We are not selling these intakes (although I would). If anyone is interested in one you can contact Magnus Motorsports directly or Titan Motorsports.

 

Interesting....

 

thats goo to hear. finally the part i was planning to run turned out to be the right choice. usually i get something only to find out it was one of the lowest performers lol.

thanks for the test Dave and sharing your findings! i would have liked to see less loss of hp/tq below 6k on the high boost run but there is always gonna be something you have to sacrafice to gain something else.

 

oh and you are running the 65mm tb on the magnus correct?

 

This test goes against the testing we saw from English Racing stating there was no losses down low. It's much easier to believe there _would_ be losses down low like this test demonstrates.

 

yeah i thought the same.. NO LOSSES down low was hard to believe over stock ported or stock..

I am not surprised that this intake made the power on top it did.. the Design is well thought out and being cast it shouldnt crack.. Looks like we have a winner.. I have 1 more manifold to test or give to david to test.. Well see how it compares..

Is the one from Australia?

 

I asked Marco about the results I saw with the losses down low because of testing I have seen from other people on the intake. He didn't feel they were out of the ordinary at all and said he'd expect losses in the low/mid range with the 4" runner his intake has DEPENDING on the turbo size that was being run. I think that is exactly how he explained it and if he'd like to jump in this thread at any time to explain more, I'd welcome that.

I'm trying to turn lasts years events around a bit, to say the least.

 

Well I think it's safe to say the Evo community would like to see Buschur and Magnus working together in 2009.

 

Well speaking for myself, I'd like to atleast see the two of us getting along again. Since it has been brought up I have extended an invitation to Marco to come back to the shootout this year. I know he always liked coming. Maybe him and I could even pull off a race against each other for fun instead of to prove something. The ball is in his court and I hope he accepts.

More testing coming soon.

 

The Magnus is working for sure. It lost quite a bit in the low to mid range. Too bad it didnt reflect all of the other testing that I had seen to date , with no low end loss. If only a perfect world hhaha.

It makes up for it on the top end though. Wonder what it would do with a larger Throttle Body on it. Probably move the power even more to the right maybe ???

 

Actually looking closer there are spots on the graph where it gives up alot of power. Look at 5600 rpm , now just looking at the graph it damn near looks somewhere around 40whp or so. That is alot to give up Just to get rewarded with 10whp across the top.

Am I looking at that correct haha

No hatin here let me make that clear just curious!!!!

 

Marcus was in Puerto Rico with Brent and to be honest,i prefer do business with them than with my own people here in the island.they open their engine and make all kind of adj. and work in front of our eyes,even Marcus,show some data logging to a friend mine.thats the kind of people we put our money on their pocket,Dave has proven the kind of guy he is too with all the help to our community,hope they team together .
