Are you running no inline air filter? Front-facing duct setups are great for cooling, but you really need a filter. Not my car, but this is the idea:

 

yea - not a lot of space there. they're the small ones, 2" but i figure it's betetr than nothing and i've had the part just sitting in my garage. figured with the calipers getting pc'd i'd finally put them on. aim is great, right into the back of the rotor.

the only thing i'm noticing is that it kind of makes the control arm brake air guide nearly obsolete, as far as i can tell. still gonna have it on, but the duct blocks most of the area the air guide brings the air too.

separate note - this is the clutch bleeder right? located under the air inlet tube. havne't bled it for a while. sorry for the grainy pic.

 

Yep. 2 person job.

 

i just used the pressure bleeder, no good?

 

Uh, those are for the intakes.

You're not really talking about putting air filters on brake cooling ducting that see no suction, are you? How is that going to work?

 

If you put a hose on it to a container its a 1 person job. But you do need to pull back on the clutch force to get fluid out of that and push the clutch fully to clean that out. And of course pump then a few times to flush.

But its just brake fluid that doesn't see heat. So moisture buildup is more of a corrosion concern than boiling point concern like with brakes. I only bleed mine after pulling trans and not even every time.

 

Pretty sure that one was tongue in cheek. I don't concern myself with air filters like him but I use an AEM air bypass valve to make sure my hoses don't hydrolock my brakes.

 

I had a feeling but sometimes I can't tell nowadays on this forum.

 

Man I've come across some threads lately where I don't know how you don't lose your ****. That EGR thread was amazing.

 

 

You got me, dammit! :P

 

general question - is there any reason brake fluid level would rise after a hot drive? no change to pads, etc.

air in the system that expanded? or just general hot fluid expansion

 

ok guys - evo is running really odd, car is kind of bucking on throttle, and when it isn't if i hold the throttle steady to accelerate it will randomly surge forward.

kind of an emergency, does anyone have any idea what this coudl be? was running fine yesterday and the day before without issue, only changes were bleeding the brakes a bit.


here it is idling, it's hard to tell with the balance shaft removed but it doesn't seem to be running smoothly. no codes or issues idling, except that it doesnt sound steady

 

If still on MAF, maybe a loose coupling? If you have a wideband, does it look normal? Maybe check plugs. And ping RS for ideas since you just got it back.

 

Hard to say but that definitely ain't right. I'd probably start with spark then fuel.
