• To soot or not to soot by Riverfurm on 17 Nov, 2007 11:46
• Got about 1000mile on my 1.6 turbo motor. It has a Giles pump set at .95, 3" SS passenger downpipe, 3" ex. with a flowmaster and runnin 20 psi max on boost.  It's in an 86 Golf two door.
  
  The back of the car gets sooted up after about a week. I played with the max fuel screw. It seem no soot no power. The max EGT I get is about 1150F under an hard pull with 20 psi boost allot of smoke.
  
  Is this about normal? My fuel milages seems good (38-40 MPG). Full boost is about 3800-4500 rpms. I also notice when the engine is hot the turbo woks better.
  
  So can I make this engine not soot up my hatch back, but still keep my new found power?
  
  Thanks for any help.

• Turn down exhaust tip. I wouldn't reduce power to keep soot off my rear end.

• the turbo likes the hot oil because its thinner.  if you want your turbo to last, don't beat on it when the engine is cold.  i try to stay out of 5 psi range until the engine hits 1/4 on the gauge.

• What they said, slight turn down on the tip.  If you are getting the soot you have room(fuel) for more boost.  IC and try and boost a few more pounds.

• Get some synthetic oil into that engine once it's properly broken in and the turbo will really love you.
