sheet metal intakes, magnus Options

[xian 1g]

:confused:

I've been doing some research into sheet metal intakes lately. I saw a couple of dyno comparisons, and read a few threads on other boards.

I can look up links to the dyno comparisons that I found. But, I was curious if anyone had anymore sheet metal shoot outs in their favorite links.

I'm kind of leaning towards the magnus. It seems to offer a fair spool up time, not too much loss in low end torque and midrange, as well as good upper end. Also, it can have the stock tb bolt right up, and correct me if I'm wrong here, the stock 1g, 90 in particular, seems to get a decent review. I've heard a few bad things about the BBK. Overall it seems to have the right bang for the buck, and it's tried, tested, and proven to be good.

again, shooting for 10seconds. Streetability is of slight concern, but not as great as good times.

thoughts and links?

thanks in advance for the help.

from what I've read and heard on forester racing. They have the least amount of power done low with the most power up top. Yes the TB bolts up on them. but be prepared to adjust your IC piping as it will now sit much lower in the engine bay.

Everything that I read was making me want the Magnus also....We are not in the market for one now but I would still be interested in some feed back on anything better then Magnus'

I've had the magnus and the FRH manifold though the FRH is cast not 'sheet metal'.

I thought you had a BJ manifold or some other strokeable commodity?

Overall, I'd say the difference is negligible. The biggest things are that the Magnus weighs less, is prettier and in my opinion, less durable.

In my head I think I noticed a slight midrange gain with the FRH, but it could have been just a perceived gain.

If you've got an aftermarket one already I'd say stick with it. In fact, if you've got a stock 1g manifold I'd save the money and spend it elsewhere.

If you're looking to buy a FRH, I'll sell you mine. My desire for an AEM EMS currently exceeds my desire to keep the aftermarket intake manifold.

The few dyno comparisons I've seen, and I can't remember where, put the Magnus and the FRH very close, with exceptions. The main difference is in power delivery. The Magnus powerband starts at around 3700, and pulls hard forever, while sacrificing a lot of tq at the lower rpms. On the other hand, the FRH makes around 10 hp less than the Magnus, still around 40 hp more than stock, at the top end. The beauty, IMO, of the FRH is the fact that while gaining a solid top-end rush, it follows the factory manifold from idle to the point where it really starts making power, with no losses or dips in the tq curve. And it's cheaper. My .02.

James do you have a link to that?

if that is true, i might be interested in a pm of price information as well. I've been thinking about the hogan, or extreme as well...

and no I currently don't have one....

to me, it's worth getting an aftermarket intake... i'm in the process of upgrading my manifolds


after that It's pretty much time to start the engine build up and transmission build up.

Kris - Get a group buy going and I might be able to get you a better deal on that AEM EMS.

DSMC FYI - I can't mention prices, but if you had a dollar for every foot in the quarter mile, thats the price plus shipping. Get together some peeps and I might be able to lower it more.

[akamiami]

aw hell yeah. now we're talking. I now there are a good number of us on the board who would kill for an aem ems. Add your names if you're cool and want to get in on this. otherwise you're a fag and like having a slow car with the stock ecu.

cool, heterosexual people who are in the group to purchase an aem ems.

[JMoushon]

Spot me the money and I'm as cool and straight as you. Does this mean no more hot man live if you get the ems?

[natedogg]

I'm not slow or gay. Add me to the list of cool, quick anti-homo's.

[JMoushon]

It is supposed to be plug and play. There are two versions, one for street and one for race. I have no idea if this applies to DSMs. The pnp version uses your factory sensors, with the option to (I believe) change your MAS. It also comes with a base map that resembles the factory ecu program. The ems fits in the same spot as the stock ecu, and will accept the three factory bulkheads, with a port to go to your laptop. This info is from a call I placed to MachV. I think I remembered it pretty well.

[ncgalant]

Their "base map" is worthless. Its tuned for 12.5:1 A/f even at part throttle. The really cool thing is watching it change the PWs for the injectors in the same way our ECU changes fuel trims.

[natedogg]

The best source of info I've found for the AEM EMS in general is their web forum. A good source for specific DSM info concerning it is on RRE's website.

Seems the best way to use it is to change the air metering to a speed density system with a MAP sensor and IAT sensor rather than a MAF. It's the least restrictive and can control fuel for a manifold pressure up to 60 psi if a 5 bar sensor is used. Of course, it could also be used in conjunction with a GM MAF translator. It also has auto tuning options for wideband O2 applications.

that's my boy!!!


i've never heard of this 2 different ecu situation before moushon. I'd like machv to elaborate.

Quite true. The one I worked on is using a stock MAS and using it to guess at manifold pressure much like the stock ECU does. That is really stupid when it will work with less restrictive and in some ways more accurate sensors.

The wideband use is really nice also. Set your desired A/F and off it goes.

[ranta18]

I wouldn't suggst using the auto-tune. This is just from what I've heard.

I think you can use the AEM 3 bar MAP and IAT sensor and be done. No restrictive MAF.

Anymore progress on that group-buy Kris?

[natedogg]

I just think they add the MAF capability for cheapo's who don't want to spend the extra money on the MAP and IAT sensors. From what I've read some 1G DSM guys are having pretty good results from the wideband auto-tune. I've read its, the Supra guys who are having trouble with it. Nevertheless, its probably a good idea to manually tune once one gets more experience with it. Seems it would be more precise.

[akamiami]

Anymore progress on that group-buy Kris?

yeah, I doubled the number of buyers. it went from just one alpha-male big dick to two, twin top-dog's. So what's the price now biatch? Let's get this deal finished. I'll take an aem 3 bar map with my ems too, so shove that down your worn out cornhole if there's any room beside garner's gargantuan gonads.

I guess all these other fags and sunday drivers are content with their mass air sensors or gm bandaids. Otherwise they'd pony up and join the cool crew. C'mon fellas, it's never been this cheap to buy so much respect....

[ranta18]

Ummm.. Kris, your price just went up 10%. LOL!

I got a good amount of tuning time on Rizzo's car w/ the EMS and I'd say its not too bad to learn. I just messed with the fuel and ignition maps, vtec, and rev limiters. There are things in there that the novice shouldn't touch.

[ranta18]

Oh, BTW... There is a bartender at the Ned Kelly's in Bloomington who's name is Chris Gross! AHAHAHAHAHAHAHAHA!


Ok, well maybe not that funny, but still a little
