New Fmic

[k3vv]

Hi guys

I was hoping anyone of you guys can help me out abit in answering a question (may sound stupid? I don't know).

I just finally finished the install of a new FMIC in my gtst33. I took it for a drive after installation (like a kid with a new toy). I didn't push the car too hard. My first observations were that the BOV flutters more than usual! During a gear change at 3500rpm (louder) and a slight rev of the car. Is this normal?

I also realised that my canon exhaust sounded more like a WRX (Blitz Nur Spec).

Can anyone tell me whether the car is up shit's creek or is this something normal???? The car is a tad bit more responsive though.

Cheers

the flutter will be louder, thats normal. its just the alloy pipes amplifying the sound.

the wrx exhaust note isnt so normal though. did you feel a lack of power? all i can think of is a bad spark, which everyone knows, makes the car sound like that.

the air charge will (hopefully) be colder now, and your boost may have raised a bit, as a result of the fmic. these are all good things. but if you have a weak coil, or weak plugs, the problem will show now.

I am sure the spark plugs were just replaced a while ago. A mate was saying that maybe I might have the boost too low and should crank that up a notch. It is not at 1 bar yet but I may want to increase it to 1 bar???? THe turbo is still stock by the way.

The FMIC is an ARC intercooler turnflow

^^^ yea the louder flutter is normal, its the WRX sounding note that i would be worried about.

Your mate is an idiot, in no way, shape or form does it have anything to do with boost.

I have a blitz exhaust on mine, and it shouldnt sound like a wrx, the only time it sounds like a wrx is when it drops a cylinder and runs on 5 instead of 6. Check all of your spark plugs and coil packs.

Dont run any more than 12psi on the turbo if you want it to last a while.

As above or check all cooler pipes done tight

^^^^^^^^^^^^^^^^^^^ Go back over the install and double check ALL your inlet plumbing. The wrx sound is a common sympton when theres an inlet tract leak. And considering you just had all the inlet off it would be the first place to look.

It depends on your outlook. Your obviously modifying for more power.... So, turn the boost up to about 1bar, wait about 5 mins on full boost and your turbo with shit itself. Then you've given yourself a reason for the big shiny high mount you've always wanted

No seriously, standard turbo should see no more then 10-12psi on a daily basis if it wants to live.

you meant lowered right

Less restriction = less boost

Less restriction = more airflow (and more airflow makes more power!)

hahaha...... yes! i should get a brand spanking new garrett!!! wahahaha.... I double checked all my pipes again today and they are all well!

THanks for your wise words dude. I am mechanically dumb but I am great in following instructions! wahahaha.....

Cheers
