shooting fire!!!!!!! help

[turbofanatic]

ok my car has sat for about a week and a half. and i just put the axle
that broke back on a couple of days ago and didn't have a chance to
take her out until last night. and after she warmed up i started to play
around and get on it. then all of a sudden a blue flame shoots out from behind me. now it didn't actually backfire as in making a loud noise or anything, but when i would get on it and then let off it would shoot out.
what could be causing me to do this? my a/r gauge showed that i was running just a little on the rich side, but not in the red just in the orange,
and i am running around 50psi on the fuel pump. how bad is? this
thanks in advanced

I dont know but i want to shoot flames out of my exhaust.

 

[TalonRacer024]

umm i hope the 50psi was a joke because i would love to see your car blow up. but really even a 20g can't handle 50psi at all and especcaily not on pump gas. if you have been running 50psi for a while your screwwed

 

[Spoolin99]

I think he means his fuel pressure is 50psi

 

[candela]

WTF 50psi!!!! theres no way.... are you talking about 50psi on the fpr, cause your turbo/motor wouldnt last at 50psi of pboost!! And btw, your air fuell gauges rich side is not red, red is lean, green is rich and the orange is stoichiometric. If your running in the orange at WOT then you are running lean. I would really like an explanation, cause I assume you are trying to pull one off on everyone here =)

 

[candela]

haha...I gotcha I saw your mod list. Either your messin with us or your talkin bout fuel pressure. If youyr at 50psi with the vac. line off then that is too high. Try to run it at 43psi with the line off, if it still runs a bit rich than back it to 36psi stock pressure...

[rubbersidedown]

thank you cyberdsm, i was reading the post and ready to go nuts because apparently no one read, or at least didn't understand the starting post. wow..

 

[boostineklipz]

i found it normal when i run 50 psi to shoot a flame or two...dont worry about it

 

[turbofanatic]

ok first off yes i was talking about the fuel pressure. not boost! so no i was not trying to pull one over on everyone.
boostineklipz:
you shot out flames when you where running that high of fuel pressure? did it hurt anything?

candella:
and if i turn down my fpr to 40 or so my car starts to run like sh#t. and what are you talking about my vac. line, but on my gauge as i stated before the red on it is rich, the green is stoichio on my gauge and now that i think about it the lean is also red. sorry i was in a hurry when i posted before. but anyhow the stoichio is still green.

i'm just trying to figure out if this is going to hurt my car or not running it like that, with it shooting flames

just messing around...i thought you meant boost...well then, i dunno

 

[candela]

What are you using for logging and tuning your car? Your fuel pressure doesnt really need to be that high. You should be measuring the pressure with the vac line off the back of the regulator and be looking at the gauge when your at idle. It is a linear unit and will increase with boost 1:1. It should probably be at ~43psi 50 may be a bit too much. You have 660's and a walbro so you shouldnt need to crank up the fuel pressure....

The fireballs aint gonna hurt nothing, but it probably just shows that either your running really rich or timing is being retarded rediculous amounts and your shooting flames. My brother car shoots flames all the time, we can even shoot them on command I love shooting them, but its uncontrollable in his car, he runs a bit rich and doesnt have any fuel control in the car...you do so you should be able to control/tune it. Post up some logs so we can take a look at them. If you dont hae any logger or engine mangement with your setup...you need one badly!

Did I smell someone venting the BOV to atm?

 

[candela]

He has a vpc...

 

[turbofanatic]

ok i have a vpc/ gcc/ pfc-fcon. but i have no logger. i am planning on getting one very soon.
and jw yes i am venting to atmosphere

 

[turbofanatic]

just wondering why was this moved to repair and maintance

 

[candela]

Our lovley moderaters or smokin' the "Monday Morning Ganja"...duh
Well theres no way to really know how your doing then withou any type of logger. Im surprised you went that far with all those parts and never really tuned your car!! Im sure youll be able to make a lot more power once you get one. Make sure to post some logs as soon as you get it, Id like to see what your setup makes

 

[jw]

Ahh.. I have VPC too and once in a while, it will shoot some neat 3ft flames . The condition is as what you have described. Bikes do it all the time just by playing with the throttle.

 

[turbofanatic]

so this won't actually hurt my turbo on o2 sensor? and when i bought the car it already had most of the stuff done to it. i'm just adding alittle at a time. but now that i think about it the guy i bought it off of shoulda had a logger you would think. thanks for the input

 

[LaserRST]

Wouldnt you be able to use the GCC to tune down your A/F ratio? I am looking into getting a similar set up for my car and I was uder the impression that the GCC would be able to fine tune problems of running rich or lean. Correct me if im wrong...thanks!

 

[turbofanatic]

yes you can fine tune with the gcc. i am not runnig rich, just not stoichio.
and i don't have a pocketlogger so it is a little harder to fine tune everything, but i do have the gcc tuned in as well as i can at the time.

but i am still wondering why i am shooting blue flames out. i went and started her about an hour ago, and i could see the flames come out this time and they were blue. please can anyone help me with this

 

[NICKYTALON]

MY CAR WAS SHOOTING FIRE TOO IT WOUND UP BEING A CRACK IN THE FLEX PIPE ALL OF THE UNBURNT FUEL IN THE EXHAUST WAS MIXING WITH THE COLD AIRGETTING INTO THE CRACK & I WAS THE FAST & FURIOUS OF MY NEIGHBORHOOD I WAS RUNNING 550'S AND AN AFC GOOD LUCK NICKY TAOLN

 

[1stGENracer]

Jesus people, use youre brains, how many people do you know that run 50psi of boost on their cars? And why would someone that has so much money into their car, but uses it as their daily driver, run 50psi of boost in their car? And really do you think his turbo could handle that?

 

[candela]

Gosh you are retarded. None suggested that he was really running 50psi of boost dude. I said that you cant cause your motor and turbo wouldnt last and thought he was joking aroun with us. Cant you see that this thread has developed farther than that point. I dont think anyone is dub enough to beleive 50psi is doable...we dont need you dumb comments!

 

[ninja0331]

Ok to all you retards, he's not running 50psi of boost, use your brains. OK? GOD!!!!!!!


Dude, check your timing, I think you might have to advance a little bit. What I guess is happening here is that when you let go of the throttle, the ECU sends fuel for the air that came through the MAF sensor, but that doesn't reach the intake since the throttle body is closed when you let go of it. So I believe there is brief moment there where there is alot of fuel (specially with your big injectors) and a late spark is not burning all of it, so this raw fuel is going out of the exhaust and since the turbo impeller is red-hot, it's getting ignited by the turbo, and therfore you see the flame, kindoff like a backfire out the back instead of out the front.

Just my two cents.
