I'm running an SC42 at 411.2 HP on the standard STI TMIC. Is it really worth going FMIC?

The turbo is advertised as a 420bhp has anyone seen more than this? If i'll only gain 9HP then i won't bother haha!

 

fmic with some meth you could potentially hit 450 bhp, even from a safety pov lowering charge temps with a fmic will be beneficial

 

Okay, that's good to know. From the kits i've looked at you can get 2.5" or 3" pipework. Any difference in performance between them?

 

Normally most impreza specific fmic kits TB side is 3" and the turbo is side 2.5"

 

I'll tell you what I've hit when I get on dyno, I'm running 2bar on it

 

Probs no use but can check my figures,

My sc42 got rebuilt by Owen Developments so not a like for like comparison.
Also figures are with delta dash so not 100% accurate.
But i am running a HDI FMIC.

 

Ahh okay the ones i've seen have been either or full 2.5 or full 3

SC42 as well?That would great i'm currently at 1.5Bar so if the FMIC + 2Bar is a decent enough difference then i'll grab me a 3 BAR MAP sensor as well haha!

Funny enough, i'm looking at a rebuild now. Mine has only lasted a month, getting Turbo Dynamics to look at it tomorrow.

 

Owen Developments did a great job with mine,
Let you know exact numbers when i have them
Andy Forrest Delta Dash 427bhp/385ft/lbs

 

we reckon I must be around 440-450 but can't confirm, that's just on vpower, needs meth map too, then I'll hit dyno,

 

Didnt Whitewagonman make about 500 on a SC 42 with meth

 

Yes 509 iirc. I think he ported some gt spec headers too and maybe ported turbo too.

 

I made 420 on an sc42 at 1.5 bar, I bet 2 bar feels mental

 

Yes that figure seems the norm at that bar.

It goes ok.

 

Nice

 

When it comes to the IC piping size, Banny_STI mentioned that most kits are TB side is 3" and the turbo is side 2.5".

Kits I've seen are either 2.5" or 3". Which one is best to go for, I'm thinking pressure wise 2.5"?

 

Id go for it this and if you zoom on the pipework you can see the pipe from the turbo is slightly smaller, yes both outlets are 3" at the intercooler but pipe always gets smaller at turbo to help flow

Put it on a reputable dyno see what it does

 

2.0 widetrack with billet sc42 and a japspeed front mount. Made 432bhp the other day at 1.5bar I think it was. Other supporting mods such as injectors and 3" system
