Shiv and co.

My car puts out a ton of black smoke at the track. Should i be worried? Everything seems to be running just fine mechanically, but i can't tell you how many times i've gotten the meatball flag b/c someone thinks something is wrong with my car.

Im running catless, btw.

 

Do you have a tune? It could be running super rich, but that's just one guess

 

Hyprocardriac.

Black smoke=OK
White and blue smoke= Not so hot.

 

yeah im tuned. But, for whatever reason, i also know that i'm running super rich. Exactly how rich? Well, i'll be able to tell ya when i get that dyno sheet from the Vishnu guys

 

rich ,what dustin said is the general rule of thumb

 

alex-- do you have a cat?

shiv

 

he just said he didn't have a cat in the first post. Anyway i think you're running super rich.

 

Cat-less will make you puff black smoke. especially at shifts. Also, if there is any oil seapage at the turbo seals, you will spit out loads of smoke. Even a teeny tiny loss. Nothing to really worry about but certainly worth keeping an eye on. Do you lose any oil between oil changes?

hey shiv.. it sok to looe a bit of oil at teh track under hard road racing right.. like 1/2 quart or so?

 

Yes it does "sok" ...

(sorry, couldn't help it)

I could get my completely stock EVO to puff black smoke under some hard driving. I would assume it would be more prevalent with a "tuned" EVO running catless. So I would say it's normal.

Now, the trick is to get flames coming out of your exhaust.

 

that would be blue smoke, not black.

 

Not sure if i lose any oil, but i'll keeo my eye on it. IF i find out that i AM losing some oil, what needs to be fixed / replaced?

 

black smoke = oil..right?? ,
alex has ur valve cover ever been taken off for cams or what now...check the seals around the spark plug.

 

no, black smoke=fuel blue smoke=oil white smoke=coolant
