My new monster

[lamehonda]

I'm glad they are doing something about this. I think they know they don't really have a choice. The car may still need a tune after they add in the cat. I don't know enough to say this for sure though.

I got a bad burn on my back and shoulders when I was 16. The worst part was not being able to sleep once it started to really itch. The good thing is that is when you know it's coming to an end. I have heard that taking a bath in some oatmeal(I don't know how this is accomplished. Recipe: 50 gallons boiling water and 400 packets peaches and cream instant oatmeal?) provides some relief. I would try this if I were you.

yeah, it was idling funny for a while after I got it back, but it seems to have self-adjusted to a slightly lower idle rpm. Not much difference in performance. I've been told I could have taken the dealership to court over this, but it's really not worth my time imo.

The worst of the sunburn is over. It started peeling today and the blisters are starting to go away.

alright...i have and have had multiple turbo cars...including an 02 WRX w/ a cat-back and aftermarket open loop BOV.

i had problems w/ the richness on my WRX too...the thing that's probably making your car run like crap is the BOV. since you now have an open loop on an originally closed loop system....so now its f'ing up your MAF (mass air filter) because there's a different amount of air going through it. on most turbo cars, changing from a closed loop to an open loop system you need to change the MAF to compensate, otherwise you car is going to run rich because the air coming in is different (less).

while your exhaust might screw up your emissions, its not going to make your car run worse if its less restricted...if anything it will run better. my guess would be its your MAF. those things cost about $300-400, but if you fix that your car will most likely be running better, especially if you've done the plugs/wires too....or you could just throw a stock or closed loop BOV back on it. won't have the fun sound, but it will prob. run normal again.

the good thing is, its most likely not done any major damage to your car as the boxer engine in the WRX is a very strong engine and can handle abuse. i know cause the kid that bought it from me beat the piss out of it, didn't take care of it, and it still ran great for him.

Someone else correct me if I'm wrong, but I believe SB300 has his terms and parts confused... MAF does not stand for "Mass air filter". It stand for "Mass Air Flow", and it's a sensor the sits in the air intake line between the air filter and and the throttle body (or in this case, the intercooler). And since I have an after market cold air intake system from AEM, I believe the MAF is not stock. Also, I don't believe the BOV has a whole lot to do with the gas mileage as all it does is alleviate the back pressure on the intercooler.

But the bigger picture about the poor gas mileage is that the idiots that put the cat on, but it on after the second O2 sensor... So I'll probably just wait a year and put a completely new exhaust system on with new headers, up pipe and wrap the turbo while I'm at it.

[lamehonda]

Yeah, MAF stands for Mass Air Flow sensor

[freakray]

Yeah, I think he's got his accronyms screwed up, that's totally UFP.

UFP?

lol...yeah i don't know what the hell i was typing when i put Mass Air Filter. lol i definitely did mean Mass Air Flow meter/sensor.

anyway, doesn't the stock BOV recirculate back into the intake/throttle body on the WRX? if so, changing from a closed loop to a open-air BOV is going to change that and most likely make the engine run a little more rich than stock.

also the aftermarket Cold-air intakes usually connect up to the MAF, and usually don't come with a CAI kit. i mean its possible, but a lot of times when people put CAI kits on the car they don't change the MAF sensor... i haven't had my WRX for a couple years, so i don't quite remember where the MAF is exactly on it.

[Uncle Pow]

Ok, yeah. I see what your getting at. And actually I'd like to get rid of the open BOV now that the novelty has worn off. Unfortunately I have other things more important to take care of on it first. I just put an Altima Red top battery in it, put down the money for a mostly complete set of factory service manuals, and I still need to get it checked out by a mechanic. The power steering and AC are in questionable condition. I'd also like to get some better speakers. Speaking of which, does anyone know what size speakers the '02 takes? It's my understanding that it's basically 4 inch speakers in all 4 doors plus the tweeters.

Correction: The BOV releases exhaust gasses, not intake air.

[stprasinz]

No, the bov doesn't release exhaust.. It releases compressed air between the intercooler and the throttle body( it can go anywhere between the turbo and throttle body, but after the intercooler keeps the inlet side of the intercooler charged, while still keeping the compressor from "surging").

The maf is between the air filter and the turbo, and when the bov releases the compressed air into the atmosphere instead of back into the intake tract prior to the turbo but after the maf it causes a rich state (ecu thinks more air is going into the engine than really is)


And the device that releases the exhaust gas is the wastegate....


And to the origanal no cat on a turbo car... That would undoubtably increase overall performance, but at the cost of emissions (pollution). The turbo itself produces more than enough back pressure.. And removing any and all restrictions after this point will increase spool and reduce lag.....

Add that to an intake.. even less lag and more power through a larger rpm range...

But none the less if that state requires emmisions.. yes that was illegal for them to sell....

Heres another one a recirculation valve is the best way to go (even a little stealthier) and you want it as close to the inlet of the turbo (yes the part that sends the air back into the air intake tract.....) As that too will reduce lag.... (it actualy will create a vortex to help spool the turbo)

And if you read all of that and either A. all ready knew it (impressive) or B. visuallized and fully understood it all.. you are probably ahead of alot of the others posting here.....


learning more and more everyday....

[Uncle Pow]

Yeah, I realized that mistake when I was changing the PCV Valve a few days ago. Finally put a heat shield on the turbo and decided if I was taking off the intercooler for that I might as well replace it while I was in there. That was an interesting process and really helped me understand the intake system better. Sad news though. I bit a curb this morning on my way to pick up my brother. Ripped my front driver side wheel and tire and bent the control arm and sway bar... This isn't going to be cheap...

[Uncle Pow]

Does anyone know if the lug nut pattern and size for an '05 WRX will fit on my '02? Someone is selling a set of wheels and tires on Craig's list for $225: http://austin.craigslist.org/pts/461495286.html

Thought this might end up being cheaper for me in the long run with the current condition of my tires.
