magnus vs jm fab intake

[LiquidX]

guys, he did say he is looking for a SHEET METAL INTAKE MANIFOLD... meaning cast is out of the question... im curious between the jmf drag/race and the magnus SMIM

Most people don't actually know about the Magnus cast manifold since it's relatively new as in since the last quarter of 2011. Besides, it's a HUGE upgrade over sheet intakes.

As for the last OP question. I'm not sure how ECUflash works with new sensors, but you can wire it in and log I would assume, but not have it utilized for SD at that time. That's the way Link works with them.

I guess the real question is, are the volt to vac/psi close enough to not cause issues.

 

[LiquidX]

Please expand on what you are asking? The sensors are designed for 5v.

ok the stock map sensor and a gm map sensor. Im going to order a smim and im wondering if I need to order it with a stock map bung or can I just use a gm map like w 3 bar so when i go sd I'll already have it. so just wondering if it will run the same so i can get my tune correct then eventually switch over to sd.

 

[LiquidX]

I think you are. Referring to the MDP sensor on the manifold. Omnipower makes a MAP sensor that is the same fit and shape as the stock MDP sensor.

The MDP sensor is for emmsions and the EGR, with a SMIM you will be eliminating the EGR and will not need the MDP sensor. When I installed my JMFAB I replace the MDP with a GM MAP and just ran a line from the GM to a port on the manifold. You dont need a MAP sensor at all if you are not running speed density but if you have one you can use it to log boost.

So could I use a gm map instead of the mdp? Will it run the same?

^ ok that's what I was wondering. Thanks.

you need this to run a GM map on a sheet metal intake manifold

i have one that im not gonna be using also cause i put my omni 4 bar on the stock location of the 2g manifold (omni power mitsubishi 4 bar) so it looks exactally the same as stock but with a higher bar rate and of course is actually a MAP and not MDP

 

[bjmauck]

You can use that or get the port welded in the manifold. But to run a gm map you can just run the rubber line to it.

well yeah you can always weld anything.. this is a bolt on solution

you can always weld your own SMIM or you can buy one that bolts on

the map sensor is most accurate when it is mounted ON the Intake manifold... less accurate if you have longer lines because it takes more time to pressurize it..... Not by much but it is still recommended to stick it right on the IM.

When ordering a jm fab its an option for the weld in bung for the factory map.

which is actually $7 cheaper!

was unaware... do that then

We don't have MAP sensors on our manifolds stock.

 

[Archer Fabrications]

We don't have MAP sensors on our manifolds stock.

we have manifold differential pressure sensors raited at a way lower bar then we can get.. but an MDP is essentially the same as a MAP only a map is the absolute pressure and not the differential pressure

 

[LiquidX]

Again, we don't have MAP sensors on the stock intake.

they have a stock place to mount an omni 4 bar. only 2 bolts! no fab needed op was asking about the bung also buddy which infact becomes a factory spot for a map sensor aka "factory mounting point for a map sensor"

you and your sly words you know what we ment

I'm aware of that there "buddy". This was dealing with another issue. I know that Omni makes a MAP sensor that bolts in on the factory MDP location. However, he is asking about a SMIM which does not have provision for an OEM MDP style MAP senor that Omnipower makes. He can get a 1/8" NPT bung welded in for an AEM MAP sensor though.

If he chose to go with the Magnus cast manifold then he would need to drill and tap or tee into another source (not recommended) if there are no extra nipple provisions.

i know there is no bung on the JMF SMIM because i linked him the adapter already that he needs and he was saying that JMF has an option to add that when you purchase it from them.. i dont know why this got so complicated what i linked him can be used for the AEM and GM MAPS (which are the same thing)

point is the MDP and MAP essentially do the same thing but monitor a different type of pressure... but they both measure pressure so i dont know why you needed to complicate stuff when he had the info he needed in relation to the MAP sensor

it has a provision if he orderes it from JMF with the bung prewelded... and it would fit the omni map sensors they sit right in there.. you do not need the NTP fitting just bolts longenough to thread in the sensor itself and the adapter into where ever on the SMIM its supposed to go

The whole thing I was getting at is the fact that too many people call the MDP a MAP sensor because too many others throw that word out there. There shouldn't be that confusion regardless if they work similar.

Frankly, I didn't see your post for 1 and 2, I didn't realize that JMF made a provision for an Omnipower MDP style MAP sensor.

no worries and i agree about the confusion of MDP and MAP sensors.. gets annoying haha

Just as a suggestion... You might try talking to Tony, ie. sparky1987. He can make you a custom sheet metal intake in aluminum to your exact specifications, add any extra ports or flange mounts you want, and TIG welds it together better than most nuclear pipeline certified welders could. The guy does excellent work and isn't going to cost a fortune to get EXACTLY what you want. You should send him a PM and see what he can do for you.
He has already made a few people on here intakes, along with other items, and I have yet to hear 1 negative thing about any of his work.
