well these are my plugs after 700miles on the tune are they ok?

 

look fine, slightly rich, exactly where you want it!

thanks for the quick reply. how can i tell, so next time ill know

 

what are you tuned on ?

neptune, why?

 

 

to really see how a plug is running, you need to look down inside the plug, not just at the ceramic area or electrode area, but down inside in the depth of the plug, use a flashlight, and you will see what i mean.

but if the tips look sthat black, you are probably running a little rich and for a turbo car we need that

 

According to this I don't agree http://www.maxracesoftware.com/spark_plugs.htm

 

interesting, bump

 

The electrode should be very white so you are too rich right now. Also just removing plugs doesn't say much unless you shut off your car in high RPMS after a WOT run.

, where can i do this besides the dyno?

 

You can do a 1st through 3rd gear full throttle pull and shut the car down on a 1/4 mile drag strip, dyno, or on any straight stretch that you can find, not to suggest anything. A turbo car makes the most power just before detonation, this leaves you with a very fine line that can be easy to cross and destroy your motor. With a street car it is best to run a little more rich that this because the motor will see alot of running time and the chances of getting some bad fuel or any other condition that would cause detonation are greatly increased. This is why people prefer to use a little conservative tune for street driving. For only 700 miles on those plugs I would say that you are running way too rich and you are probably losing a noticable amount of power. Use a good wideband meter to tune and try to stay around 12:1 air/fuel ratio. Any good dyno shop should have a meter that you can use. Also if you are running low boost and turbo is your only power adder you might want to try the bkr6e plug.

Do your self a favor. Tune a car at 12.5:1 then at 12.0:1 then at 11.5:1 then at 11.0:1
Let us know if you actually see a major power difference that makes it worth running a leaner mixture.

In most cases the power difference between 12.0:1 and low 11s a/f is minimal.

Agreed. When I tune AF's the butt dyno doesn't tell me much, but if I change timing even a little bit the butt dyno tells me torque went up....or down. This is strange who tuned for you on Neptune, because not many people tune Neptune.

take a WOT pull in third gear on a straight deserted road and shut down when you are in the higher rpms (don't let it idle). Then pull over and read the plugs/take pics.....there should be a nice black ring on the base indicating a rich condition in boost. This is a good thing. If you are idling and they are black like that your gas mileage will most likely suffer. Did you get partial throttle tuned at all because it doesn't look like it if you pulled those after idleing/driving around unboosted

ummmmm, 11:1 is a little on the rich side. if you tune 11.5-11.8:1 under high boost, that's plenty on the rich side. although, you're correct, the power differences aren't much, but you start tuning 11:1 you start fouling more plugs, worse gas mileage, higher inj. duty cycle, etc. there's just no need to tune that rich in my opinion

and not to mention an actual increase in chance of detonation

Injector duty cycle & gas milage under boost... Who cares ? you are under boost.

Fouling plugs at 11.0:1 under boost... it doesnt happen.

I was just stating a fact, a little richer is not going to effect performance enough to the point where it is worth risking running a leaner a/f mixture on a street car...

So you honestly believe that tuning a boosted street vehicle at 11.5:1 during wot boost conditions vs 12.0:1 or 12.5:1 makes you **** to detonation ?

 

next time why don't you try using iridium plugs ? just my .02

He is using a great set of plugs.

 

they look a little on the rich side.

No not 11.5. I meant more like in the 10's or lower. Let me find the article were i read this.

I never said anything about 10s buddie

so you wouldnt agree with my above statement that his plugs are fine? why not, they are definetley NOT in the lean range by any means, and like MTBER says there is minimal difference from mid 12s to mid 11s. his burn looks to be probably a little rich, but unless he came and complained about some really crappy gas mileage, then slightly rich is okay in my book. my plugs look similar, notice i say similar. and my car makes great power and has been running for over 2 years without any problems, so i just figured i answered his questin in a decent fashion.
