Magnus of Forrester Manifod?

[TRBOTSI]

People can preach all they want how they picked up this much ariflow on this intake and then Joe across the block picked up this many mph in 1/4 but until someone steps forward with back to back manifold numbers, all this talk is arbitrary...

Arbitrary yes, but nobody is going to do a back to back test, so impressions from members with particular manifolds is better than nothing and helps.

You said you have a FRH, why not post your impressions such as Tevenor or Killurv8 did?

I have a Magnus same as Tevenor however I have not done enough driving with it to give a detailed account of the driving experience.

Yes, all these reviews help and are certainly better than nothing, but I think an independent vendor should do a test on the 3-4 most popular intakes. Much like AMS did with the cams. I'd much rather look at dyno sheets than take someones' word. It's hard to argue with the numbers right in front of you.
By coincidence I have the FRH, a close friend has the Magnus, and another close friend is purchasing the BJ's very shortly, perhaps we should throw together a comparison on one of our cars.
And I don't feel that I've driven my car enough WITHOUT the FRH intake to really give an accurate review. I threw all the performance parts on at once and don't even remember what the car felt previously. I certainly don't like the weight of the FRH in comparison to the sheetmetal intakes and I do know the FRH helped me dyno 500whp but I'm sure I could have done it with the Magnus or the BJ's as well.

FYI, we sell the 2g Magnus intake with a bung welded on for the factory MAP sensor so you don't get CEL's. And we have the optional coil mount.

thats a nice manifold, is that how u sell them and do you put the coil in any other location so your not blocking the pretty polished manifold , also is that the fmic piping from yoru kits thanks

We are not talking tube framed cars or back halfs here. We are talking full body cars.

the magnus manifold is poorly constructed... where the runners meet the flange has a large tapper, and does not have a smooth transition...lots of turbulance is made here. the magnus manifold is just shinny..only for looks... the busher racing manifold is tha way to go.

Odd. Mine is fine. A large 'tapper'? Mine is very smooth.

I have the same problem with my Magnus intake, but you know what? A dremel tool is an amazing thing.I say the small hassel of fixing that is worth the gains achieved from this intake.

Yeah, but for a $600 part, you shouldnt have to "fix" anything on it. That to me is kinda janky. I'm not down.

Mine is perfect.

You and Tevenor are using the 2g model.

My 1g model was constructed the same as NeoStreamGSX said. Big lips all the way around where the flange meets the runner. The plenum also had a bunch of oily goo filled with metal shavings that needed to be cleaned out.

My 1g magnus is perfect! The transition from the runners to the flange is flawless. it came out of the box with a polished mirror finish. I could have eaten my dinner off the intake.

I actually never got to use it because I put a 2g head on that is port matched for a 1g intake. So I have it up for sale.

What are you talking about? Are you talking about the flaring on the runners? That's called a velocity stack, and aids in airflow. I'm serious, I really don't know what you mean, could you maybe post a picture?

The size of the runners don't match the size of the head flange. The runners are larger and/or not shaped correctly to match the head flange. The runner side of the head flange creates a lip inside the runner. Each port was different depending on how the runner was bent to go from round to square shape of the flange and where the runner was placed on the flange.

My port work probably isn't the best, but it reduced the sharp edges all around the inlet of the flange quite a bit.

I also just checked the flatness of the head flange. I think it's also going to need to be resurfaced. Looks like it has a gap of a thousandth or so in one area.

I'm not even going to touch this one.. Ian it's all yours.

Ok maybe a little. Have you ever looked inside your head where the air goes in and saw those little things in the way called valves? How about when your air flows through your throttle body an that thing thats sideways right through the center of your throttle body when its wide open? And your complaining about a small lip on the inside of the manifold? The fact that the air has to go around the throttle plate sideways in the throttle body or flow around the stem and head of the valve when it enters the motor are two restrictions that pose flow problems WAY larger then your lip on the manifold and there is nothing you can do about either.

Bro put your dremel away, your not a flow expert, install the part and enjoy your 40-50hp increase.

 

[sunflashx]

The lip was around a 1/4" of an inch in some of the corners. That may be small by your standards but as common as it is to port match the head to the intake manifold I would think you'd want that to be a smoother transition than it was. Just because there are some restrictions you can't do anything about doesn't mean everything else is a wash.

Maybe it didn't really matter, but it makes me feel better having smoothed it out.

No shit. maybe I should look into a punching bag or something .. Ok my bad.

Hey if you have a lip that big then smooth it out, mine didn't have a lip that large anywhere. There was a very small lip (less than 1/8th) on my manifold which I didn't even consider as a problem.

If you had a 1/4 I can see the thought behind smoothing it out. However still with the restriction built into the design of a head and throttle body I just can't see smoothing out that lip on the intake manifold doing any at all. I understand the "makes you feel better" thing, hell the things I did to my exhaust to make it flow better probablly didn't help, but it makes me feel better.

The flat area of the runner was 1/8th or less, it just has marks on it because I touched since I was already in there. The corners and a couple of the side areas were the bad parts. It's hard to tell, I should have taken some pics before hand.

Had it been like you describe, I would have left it alone.

might be off topic but, i just finished my sheet metal intake install! i did alot of reading and researching on the different manifolds out there and i think they all are pretty damn clean! personally though for me, i liked what the bj's manifold had to offer! so that's what i bought! i've never seen the other competitors manifolds in person but the bj manifold is flawless!!!! i just can't believe you can buy this kind of quality part for the price! thumbs up on the bj intake!! 125 plus mph traps here i come!!!!!!
