Puff of smoke at WOT...

[Jeremy Hohn]

I have had this problem for quite a while, and I figured it was possibly a dirty MAF sensor, so I put it off until I put my 80mm with the new sensor on, but it is still doing it! It really only does it when I am at WOT and leaves a black residue on the chrome exhaust tips. What causes it? I have literally had the engine torn apart by the best, and this still frustrates and embarrasses me... thoughts???

I have the same problem and it would be cool if someone could figure out what this is.

Depends what your seeing.

First there is a bit of unburnt fuel that is getting puffed out of the exhaust, You might be seeing this.

Also at WOT your burning alot of the lingering carbon out of the engine.

I think this is normal, my car does it and its in perfect condition. I only noticed it once though when reving high at a stop.

Many SHO owners report this "problem". It's because they run pretty rich at WOT so that puff of smoke is unburned fuel.

 

[SHO 3.0]

Mine does it any time you get on the gas, even if it's just a little bit, when you get on it fast, or rev it up it'll puff a little, the more i get on it or rev it the more it will smoke, but after the secondaries open up, it stops. So it's only rich in the low rpms with me.

Thanks guys. It really happens at WOT and otherwise the car purrs nicely, and there isn't any power drop when it happens, so I guess I will remove this as a problem and chock it up as normal.
