During normal operating conditions, the exhaust emmissions seem normal. But, when I go WOT and the s/c kicks in, I can see a lot of black smoke come out of my tailpipes.

Is this normal?

And, is there anyway I can determine if I am running rich or not? I have yet to install my gauges.

 

I haven't noticed any black smoke from the exhaust when I go WOT with my S/C'd 6MT. But I don't normally look in the rear mirror that closely when going WOT. I'll look for it next time and report back. I do notice that the exhaust tips get a bit blackened over time which indicates that my car is running rich at times. This is normal according to CompTech.

The only accurate way I know of to see how your car is running in regards to A/F ratios under WOT is to have it dyno'd. Fortunately, I had CompTech do a dyno on my car right after I had the S/C installed and everything looked within spec.

 

Yeah, I don't usually look back either. It's just that I went WOT and I noticed that the car behind me tried to keep up. When I glanced in the rearview mirror, I could see a dark grey cloud of haze in his headlight beams.

 

lol pwned

 

That is normal as the fuel pressure will rise quickly causing it to go rich for a bit. In addition, at WOT you are also running richer that you would be NA due to the same fuel pressure increases.

 

How does the S/C pull??? You'll need to give me a test run.

 

At first, I didn't notice it as much. But after driving with it a bit, it is definitely faster than without.

Sure, anytime.

 

I see many cars blow out some kind of smoke under WOT, make/model is irrelavant, have seen it on all kinds. I thought It was just blowing out any kind of buildup.

 

Just an FYI - seems like the s/c will make the car run even more rich. I'm not an expert but I found this on the web since I'm researching the viability of me getting a s/c. Bottom line - get the CL-s pulley to solve the problem.

From what I've experienced and what CompTech told me, the S/C only makes the car run a little richer under near to WOT conditions. In closed loop conditions (slight thottle), the S/C doesn't do anything and car should run as it does stock; like cruising on the freeway.

 

I don't have the S/C & I see that smoke sometimes. My exhaust tips are always black within 2 days of washing them.

 

No the FPR will make it run richer. It goes leaner with the HBP because the pump cannot keep up with the additional pressure required to keep it at the same ratio.
