fmic

[$RUSSIANSPEED$]

hey..have a question for you that have installed and fmic....should i go with 2.5" or 2.25" piping?
i heard if i go with 2.5 ill have to get a different fan or something ??

and what size of the core should i go with?
thanks.

2" on hotside and 2.25-5 on cold.

2" on hotside and 2.25-5 on cold.

other way around... if anything you want the cold pipe to be smaller, as the air in it is more dense. you do this to avoid pressure drop. 2.5" is a b**** to fit in the hot side, and honestly I doubt there are benefits to larger piping, but I was stubborn and ran all 2.5"

theres no point in having piping larger than your IC in/outlet, so make sure you match that. I'd go with a 3" thick core if you can as it is more efficient than a thinner one. the only difference piping size will make is what adapters you need... the turbo needs to go from 2" up to your piping size, the maf (if you choose to relocate it) will need 2.75 to piping size, and the TB will need 2.5" to piping size...

yeah that does make sense smaller pipes since we have a small turbo...

 

[Wagonbacker9]

really, any bigger than the compressor outlet shouldn't have any benefits... since the maf is 2.75 i wanted to go bigger, I don't really claim theres gain in it. lol

as awful as that is to admit..

 

[$RUSSIANSPEED$]

so best thing to do is go with 2.25 piping.
what size of intercooler 27x5.5?

 

[littlemimus]

that should work. i was looking at a 26x5.5 or something like that.

 

[Wagonbacker9]

sounds fine..

i am also currenty getting fuel cut and ive been doin some reseach on the reflash...should i do the reflash before i get and fmic or after?

 

[Wagonbacker9]

if you have a titanium you are very likely already reflashed. do you know what your boost is at?

 

[$RUSSIANSPEED$]

6-7psi not sure if the gauge that accurate...

 

[Wagonbacker9]

odd that its fuel cutting that early... I don't fuel cut til about 10, and thats with a FMIC.

speaking of... time to order my WGA..

 

[$RUSSIANSPEED$]

u run 10psi with just an fmic?
and are u gonna go with forged wga or atp?

 

[Wagonbacker9]

I ordered a new forge wga... which I should have done a months ago.

i do NOT recommend running that much boost. you're basically asking for trouble.

 

[$RUSSIANSPEED$]

what mods to u have? that u run 10psi?

 

[Wagonbacker9]

a leaky wga, and a FMIC. lol. as I said, NOT RECOMMENDED.

when I get the WGA in, I'll be going catless as well.

 

[$RUSSIANSPEED$]

haha thats no good...with the forge wga do u still a boost controller?

 

[Wagonbacker9]

I don't (and won't) have a boost controller. 10 psi was due to the leak only.

 

[littlemimus]

what mods to u have? that u run 10psi?

here dude...or dudett. lolz heres a thread on what u need to run ten psi safely. be caruful. http://www.mazdas247.com/forum/showthread.php?t=123677826
