Second, Gary (or am I thinking of the guy from FFS?) has proven himself to understand less about tuning and the operating principles of the internal combustion engine than half of the mouth breathers on CR. To allow him to "tune" a car is foolish. To do it and not check EVERYTHING he touched right behind him is crazy. To then flog the car competitively without having verified the tune AFTER HAVING ALLOWED ONE TO BLOW UP ALREADY is reaping what you sow.
TDR motto - when you don't know what you are doing, make it pig rich and collect the check.
^And that's the other reason for the sooty oil.

TDR = TrackDog Racing = A Gary. Texas. See: CR "more money than sense" Stoly 1.6 IRTB build fame. Apparently also blows up customer motors.
FFS = FAstForward Superchargers = Tom the yo-yo master. Arizona. Thinks fuel is a better at cooling an intake charge than an air to air intercooler. Believes pushing an MP62 to 150-175% beyond its manufacture rated redline is a solid base for product design.
Someone correct me if I got any of that wrong, I'm still learning.
The only vehicle I've ever had that "immediately" turned the oil black is my FE big block powered 74 F250. It does this because bad rings and stupid rich. I would seriously consider leakdown and compression on this motor, and possibly confirming the wideband reading with a different wideband, if possible. Something is getting into that oil, and my money is crap getting past the rings.
But hey, what do I know?

Well, we all like the "rest of the story" don't we?
My friend had tracked his '92 for years normally aspirated without issue. But, he wanted more powah!!
So, he took it to TDR to install a SC. On the first day my friend had it at the track, it blew a piston (blowby filled the catch can until it overflowed -- my friend pitted because the car was feeling "loose." There was oil all over the engine bay).
TDR rebuilt the engine for him (I don't know the financial details) and put in some lower-compression forged pistons (probably Supertech 8.4s). I got to see the original pistons. They looked like they had been subjected to an industrial sand blaster shooting heavy grit. Every one of them. At least one of the pistons had broken ring lands. TDRs story? "Looks like old detonation damage." Geeez.
The kicker? Engine was making sub-140RWHP when it blew.

That's actually pretty hard to do. You have to REALLY SUCK at tuning to do that. I would imagine a stock Miata spark table, premium fuel, and a rich tune could keep you out of detonation at those power levels with anything other than a cold side heat pump supercharger. And even then... sheesh!
Is your buddy running astupid side cold side unit?
So, TDR and TDR destroy engines and For ****'s Sake is a yo-yo? Got it.
I have a terrible time keeping my m.net gurus straight. I don't ever go over there.

It's on the hot side with an IC. Not sure if it's a 45 or 62. It is a 1.6.
He's pretty fed up (understandable). He's watching the K swap threads with interest.
