My experience on various Mazdaspeed aspects...

[SergMSP]

SMIC:
I went with the dual bpv/bov setup. The mod that i felt more gain with was the SMIC but in the end to make it all work good with other mods, ide say i should have waited and just gotten a whole FMIC/CAI kit...in the end i think i would have spent the same amount of money but maybe in the future.

Relocating Maf:
I was against it but everyday im leaning more and more to do it. I'm still stalling with dual bov/bpv setup...not sure if i have to tune both vales a little more, not sure if i have to look into checking my vacuum lines, 505zoom has a thread
that i might try, also it could be one of my hoses are loose. So after trying everything possible not do it, ill let you guys know what happens with this stalling s***...

Alejo, thanks dude, see if you can help me out with fixing my stalling problem...

frustrated...

For stalling issues, i'd check your WGA. Pull off the hose running to it, try blowing in it, if air goes through, then the diagrpham is shot. I'm running recirc with just a BPV, and i kept having stalling issues, frustrated the piss out of me and took forever to uncover, but thats what it was.

I disagree with your opinion on the SAMCO I/C Pipe. I tried it on and off to see if there was really a diff. and yes, there is one! It runs smoother, not a big diff. but maybe similar to your Grounding Cables findings

Samco Pipe:
the little metal piece on the nipple broke on mine after like 2 or 3 weeks, so i am questioning the quality now. Might be selling mine soon...its red. If you have stock pipes its definitely better but i recommend to not plug the little flange since that is the reason mine broke..(could superglue back one though..)

 

[BOOSTR]

Has anyone ever performed a dyno test on the smic vs fmic to prove or disprove the notion that one is better than the other? I'd love to see one for the MSP. Do a search for CustomMSP's smic and look at the dyno run in 3rd gear @ 9 psi. A 20.32 HP and 15.2 TQ increase is not to shabby!

Here's one on a different car, a turbo Jetta. http://www.tyrolsport.com/sidemount.htm

 

[kamon8404]

That gain with the customsps smic seems well worth the money if you are going to stay with low boost apps.

 

[MSpeed2397]

Kamon I absolutely agree...if not looking to make huge power and not looking for bling it seems like a much better alternative. I think we should come up with a power/money/mod list in this thread. If looking to make power in this power range - buy these parts - for this much cash. It would be interesting to see what comes out

ok, now try this

compare STOCK vs SAMCO vs METAL pipe

see which is better

ovbiously SAMCO is better than STOCK but METAL is better than STOCK and SAMCO

METAL wins overall

Metal is just as expensive as SAMCO...maybe samco looks better, but does it performs better? what about over time?
Metal might get stained overtime...but rubber tends to fail over time...keeping in mind the oily atmosphere in which it will be living for years..

i think rubbers gives away faster than metal

 

[MSpeed2397]

I have never seen the samco in person, but I thought it was a hardened silicone pipe that would not expand. To me it sounds like the samco is just a long silicone coupler...that seems lame. I think the appearance of metal is much better as well as the performance. Get custom Al pipes made with bead rolled ends and you have a system that is 100x better.

[MSP#735]

consider the heating and cooling properties of; plastic, silicone and metal...thats the main difference. yes, plastic and silicone will flex but the main difference is how much cooler the air is once it reaches the IC....right?

with that said, Samco IC hose and upgraded SMIC (first)

 

[Alejo_NIN]

well, understood what you said but...

see how short the pipe is?? what kind of air heat loss are we talking about??
do you know by a fact that air is being cooled at all by this segment of the piping??

 

[MSP#735]

its the "HOT" pipe, its called that for a reason. the cooler you can make that pipe the better off your engine will perform. im just saying that silicone cools off more effeciently than metal.

[Alejo_NIN]

well, you might be right...after all...we're just discussin stuff

i rest my case against the hot pipe, we just don't know

 

[yashart_mp3]

^^

1) Aluminum has great cooling properties (dissapates heat extremely well/fast).

2) Aluminum won't flex

Aluminum Hotpipe > Silicone Hotpipe : anyday of the week. Most people buy the samco because its cheaper and they can say its a mod.

**edit - now that I think about it, silicone is more or less a ruber. Rubber is an insulator. So in theory, the Samco hot pipe would keep more of the hot air inside the pipe. Aluminum on the other hand, would allow heat to transfer to the metal, thus dissapating heat better.

No one has anything to say about the injen intake??????

 

[Alejo_NIN]

about the injen intake??
lol

DROWNS ENGINES!!

Injen Department:

WASTE OF MONEY
Having a cold air intake, in my opinion, is a waste of money.
You will have to be very careful when going thru puddles as it may flood your engine and thus bending rods and such...
too costly for 299...
RAM in the other hand works better, and some even go as fasr as saying the stock intake works just as good.
Imagine this...
Cold air>Turbo(blazing hot)>Intercooler>Throttle body
Cold HOT cold again HOT again

in theory, cold air doesn't do much....so having ram air is so much betetr, and the piece of mind of not having to worry about puddles is PRICELESS

 

[MSpeed2397]

Eh, whichever, I don't think it really matters too much, more for the sound. I have one that I got used, and I'm not gonne lie, I like it. I can see why it's not worth the money though for sure.

 

[kamon8404]

i think that i'm going to make an "sri" type intake out of my stock intake piping. Its cheap, easy, and serves the same function. Can't beat that.

 

[jeffmsp]

had the aem intake really liked it, faster spool, more timing from iat sensor. Just make sure you have a way to deal with fuel cut in the winter months. Lots of turkey or BOV sound depending on your setup.

 

[kamon8404]

I will be running the bov/bpv setup ... maf in stock location ... ss afc

 

[Alejo_NIN]

let us know how it turns out
