Please help me ease my nerves!! i know black smoke means unburned fuel but...
I was doing burnouts with a friend of mine on a sheet of packed snow (ice) tonight in a parking lot... one time i spun the tires up to 105mph.. (didn't mean to go that high) and when i finished a friend of mine said it started pouring out "all this black smoke".. i've asked a few people and they said that it means i got carbon buildup and to be careful cause that how you burn a valve... but... with the way i run my car and all the treatments i put in it there should be NO carbon at all... please give me your INDEPTH thoughts... thanks you in advance.. iim freakin out... my car? blowing smoke? NOOOO!!!!

oh yeah, by the way... after my friend told me about this...i poped the hood and push down on the throttle trigger by the head... i must have revved it to a good 4, 4500 or more doing that and i was looking at the exhaust the whole time... no smoke at all... just a LITTLE white (condensation, not coolant) and it drove/ran fine on the way home even at WOT no noise nothing... and i couldn't see any smoke in the rearview (although it was at night)... just wanted to add that to the equation....

heres what happened-
dont worry, my rear bumper is burnt because i did so many times
your TB is wide open and your motor is spinning high
so you have lots of fuel being dumped in. you close the TB at once and then bam- no more air
so now the gas in there cant burn and comes out the exhaust, expodes in there causing popping and black smoke and all that good stuff, even little flames out the back
at the track i would trap around 5200rpms
and then i'd get off of it real quick
yea, my bumper is burnt

ohh i should probobly add this is a disclaimer-
if your driving normaly and there is black smoke, there is a problem
just go look at your bumper.
mine looks like it has 2 black racing stripes- i didn't have exhaust tips though.
ps
your not going to burn a valve unless you do something REALLY stupid-
well not at our power levels
