Smog Check Cobb DP
 

i just got a smog check epic fail with cobb DP !!! the numbers it was producing was like double and some instance were triple of what values i should be in.

I thought they got rid of the sniffer test in cali ... i guess not

Well it should have failed visual anyways.

Run 2-3 gallons of e85 - should help with the sniffer test...

.. and what is up with that mod list, half of what you have on there makes no sense (ie, the tune you are running with those mods... hypertech or Cobb OTS stage 1, Corksport and Cobb cold air box, etc) and unless I missed it no HPFP internals/pump?

im running 3 gallons of e85 in my bitch with the cobb dp and it didnt pass the sniffer test. Luckily I still managed to pass though :bigok:

how u pass the test!! i fail epic!, won't e85 damage my engine if i am not tuned to it? and don't i have to let my computer adjust to the fuel mixture?

they grayed out ones mean i previously owned. and yes i don't have a HPFP yet and my car, i believe in handling first then speed so i did suspension first, next mods will be fuel pump and inter-cooler. my car runs just fine 130,000 miles original owner since 2007.

i am special i don't get visual test

You are worried about damaging your engine with e85 but yet you have all of that other crap installed without upgraded HPFP Internals? Who gives two fucks about what you used to have installed? You shoukd be thankful that you have not ZZB yet.

Good for you that you don't have to worry about a visual but have you performed a compression and leakdown test to confirm the health of your motor? That seems like a lot of miles for the Dixie Cups that Mazda used for pistons on the Gen Ones. Some people on here have passed visual with a catted downpipe or a second cat delete so I don't know what to tell you.

himurax13 i don't know why ur all getting pissed off for if u look closely at my mods like a good amount of them don't do anything much to the engine. so why would the stuff i install damage anything? no i haven't done a compression & leakdown test, and all that does is tell u how good ur rings seal i believe, i think u have to crack the engine open to really determine the health of the engine. but i can tell u i have no smoke coming out of my exhaust, runs strong.

Out of curiosity, are you at least monitoring fuel pressure regularly?

You realize you have more than a few flow mods...

They might not do much to your engine with an OTS stage 1 tune - but you have almost all of them to include a downpipe...

Maybe he is new and dosent realized you should have fuel pump internals for a DP.....oh wait, join date "Apr 2009"

And who keeps parts they dont have any more on their mod list? It looks like you have things on the list to just try and make it longer.

Pissed off? No I am just Awnry. The last Jackass I met that was fully bolted minus the HPFP internals had Fuel pressure dipping into the 1300's during some 3rd gear WOT logs. I told him never to go WOT again until he gets that issue resolved.

A properly performed compression and leakdown test can reveal the status of your rings, valves, if you have a blown head gasket, and if it is time to rebuild your motor. If you have to crack your engine open, you might as well rebuild. My engine was running strong and had no smoking but it had massive blowby and crank pressure and it took only a few months to finally die. What I am trying to say is that it may be your motor and not your catted downpipe is the reason you are not passing smog. Also, did you let your car cool off before they started the smog test?

ya i just checked it on my way home from work crusing 80mph i am getting 1745 on fuel pressure. not bad right?

ya i noticed the car isn't getting any quicker but i've been just lagging on the fuel pump.

lol i do haha. so that when i look back i can remember what i had. thats the same thing i did when i had my mr2 turbo.

post some wot logs so we can check the pressure.

ya i heard about people blowing motor while punching it without fuel pump. i did a couple of pulls when i got the downpipe at 80% throttle and my fuel pump was pushing 1800 that was last year. today on my way home cursing at 80 i got 1745. i am just debating if i should keep the car if i do i'll fuel pump and intercooler if not i am going sell the car as is or strip it then sell it.

blow by u say.. hmm if the gasket or head is bad i should get oil in my fluids but none yet. well can't hurt to do a compression test, i've been wanting to have someone crack the engine open to clean the valves.

It's not partial throttle cruising that will cause the pressure drop that is dangerous. It's WOT that does it...

and how are you hitting 1745+ on stock internals on a map that only commands 1669? ... stock internals will not hit 1800 on wot unless you are counting the few cells that spike after you let off the throttle completely.

People are just generally puzzled that you have been on this site for so long - have spent a ton of money on suspension and flow mods (which ARE power mods, btw) to include downpipe and an expensive cbe and more than a couple of appearance mods but haven't upgraded your internals yet.

It's your car, after all, and you can do what you want with it... although I do question your overall knowledge considering the above comments.

that will have to be later on too much traffic right now if you live where i am u would understand the traffic lol

Dude you have no idea what the fuck you are doing. Try reading a little about your car before modding it? Damn.

from what i was told gen1 are more forgiving on not having a fuel pump then the gen2, and i don't know how i am getting 1745 on a command thats suppose to be 1669. i would just have to say it was luck since not every car is built exactly the same even tho its the same car. i guess i have a better then avg fuel pump. i just put my foot on gas and look at my ap and it says 1745.

what are u talking about? u need to read the topic on this post before u tell me to read.
just cause you like modding your car like that don't me i like to mod my car like that. and i don't have a problem modding my car. if you read the post it says SMOG not how do i mod my car.

why do people what to give u their 2 cents on how u mod ur car when my post has nothing to do with that. and i am not asking for anyone's help on how to mod my car i am ask for smog check. so if you want to talk about how ur mod kicks more ass then other peoples mods then go to another topic plz.

Its not how much your Fuel pump pushes, but how low it dips to. The only real way to tell is to look at a few logs.

It kills me when some people upgrade the suspension and stereo (in this case a downpipe) before they instal HPFP internals. The stock suspension is pretty good. It is even better with a decent RSB. The stock brakes are also very good, but even better with S/S braided lines. In your case, if you keep it, get the Fuel pump internals before getting the intercooler but with the mileage on the car, it might make more sense to stock out, part out, and trade in.

I'm not required to follow your guidelines. Fuck off. I'll give my opinion if I feel like it. Also, I never said shit about my mods.

All I'm saying is you are a dumbass. You installed a DP and only checked the HPFP at 80% throttle when you first got it which was last year. That is pretty stupid.

LOL @ OP getting butthurt simply becuase we are telling him he needs HPFP to avoid ZZB. Dude gets angry cuz people trying to help him. Oh well.


Also...is Cobb DP catted or non-catted? I'm assuming catted, otherwise not sure why OP is surprised it failed.

LOL dude go smoke some weed and calm down. .

I'm literally high right now. And I'm not mad. Just because I call you a dumbass does not automatically make me mad. I am actually entertained by your ignorance.

if dude wants to blow up his bitch let him. I look forward to a new thread "why did my car blow up?"

its a catted DP, there is only 1-2 people in the comment that i see that have good intention of helping me out. the rest is just there to talk shit as u can see. if they wanted to help then the people with smog check or dp should give their experience on how they pass the smog and what they did not go your a dumb ass for not upgrading ur fuel pump and then start talking about everything non relating to the topic. i already know i need a fuel pump i don't need 50 thousand other people tell me that. bottom line fuel pump at this point right now is not going to help me pass smog so why are we still talking about fuel pump.

I passed smog using the money mod if you know what i mean. You will fail with the cobb downpipe otherwise.

smog check not fuel pump thread again. so if i go throw on a fuel pump right now i am going pass smog if not then it does me no good.

save up 150 to 250 and just pay to pass lol problem solved.

i know exactly what you mean, that was my last resort i wanted to do it the right way.

last resort, i wanted to do it the legit way. since its a catted DP wonder if anyone passed but a simple question came out to a whole lot of off topic answers.

the answer is no you wont i tried a few days ago.

thanks.

Umm, how about reinstalling the Stock downpipe and midpipe? That will pretty much allow you to smog "the right way" and you wont need to get HPFP internals.


PROBLEM SOLVED, please close thread. ;)

THEN BUY THE FUCKING FUEL PUMP INTERNALS AND QUIT WASTING INTERWEBS

there are no legal aftermarket cats as far as CARB is concerned. YOU WILL NOT PASS. EVER. unless you know someone. or the guy just does not care. but if you want to do it "right", then take it off. there is no EO# on an aftermarket cat. it's just that simple.

to pass CARB smog test legally (as you say you want to do it), then you can't have an illegal downpipe on. and all aftermarket downpipes are illegal. correct me if i'm wrong, but this is what i have gathered.

For our car it is. :(

shit some places wont even pass you with an intake let alone downpipe catted or not. This entire thread was stupid.

The only reason people are giving you advice about HPFP is because you have bigger issues at hand than passing some Emissions test. No point in passing an emissions test just to have your motor blow because you did not have enough fuel pressure.

HPFP > emissions.

that might be true but i've driven it 130,000 miles no problem. i don't think its going to blow unless i am going do something crazy. my smog is actually due in a month so i think thats more important.

the thread is only as stupid as the comments if people post informative stuff then it won't be stupid but if ur just going to criticize then i guess it is what it is. i was hoping that people would leave positive info so that later on people can just type it up and the info is there.

it was a pain in the ass to get to some of the bolts and i actually snapped of one of the bolts when i was installing the DP had to get a stud back in was a bitch. if i have to put the stock DP back i would just get a race pipe instead of the cobb DP.
