• what ever i don't care honestly

• HOLY EFF
  
  I just  drove her up and down my street this time WITH the turbo connected up. SWEET JESUS.
  
  hit 20psi by sort of accidentally on purpose by accident and blew the rubber line to my boost gauge out of the intake!!!!
  
  the change from 10psi to 20psi is just NUTS. Why does no one else stress this more?  
  
  it starts INSTANTLY... It sounds totally different... It makes a deep bogging sound under load at WOT accompanied by a screaming sound (turbo) SO i've been told.
  
  I didn't drive it like crazy, the fuel screw is still pretty far out but holy EFF it's a different car.
  I finally got the car i bought back in oct/nov today.
  I'm still shaking. It's not what i expected at all. and it's not intercooled yet...
  it really likes to break the tires loose in 2nd on the gravel when it starts to boost. If i'm on a bare patch it just LAUNCHES. Definately raceable to my parents TDI now ...
  phew what a ride...
  
  
  on a more technical note there was some oil in the intake when i took the hose off to make the boost hose  fit better. The exhaust smells oily and LOOKS oily but im guessing that is just because the rings need to seat.
  and it makes a really deep mean noise when letting off the pedal after boosting, not alarming just ... loud and really deep sort of a    WAAAAAUUUUUUUuuuuuuuuuuuuuuu

• Congradulations Eddy it's a bouncy baby turbo diesel!!!
  
  Nothin' like diesel torque *and* that feeling when the boost kicks in, huh.  And there's something about figuring that you built the sucker from the ground up with your bare hands.
  
   :lol:  :lol:  :lol:
  
  Whenever I get the urge and my foot "accidentally" calls for boost I get this big grin and my wife just looks over at me and shakes her head.... "not in front of the children you fool". :wink:

• hah! did you get my pm?

• Whoops... forgot about your PM... you got one back.

• Congrats Eddy!  What else do you have to do on it?  I'm glad you saw this through.  
• #186 by Smokey Eddy on 30 Jan, 2009 21:24
• adjust the downpipe and weld up some 2.5 both sides exit exhaust
  
  then make my shroud for the taurus fans and slide the intercooler in there. but that's not for a little while. I think i need a job before i do that to pay for stuff im going to break.
  
  Edit: and clean the garage...
  while Mika was outside i laid down some solvent to clean up the garage floor.
  
  oh and Vince, the injector body works perfectly! no leaks!
  
  Edit: what does it mean when it lurches and chugs forward at low rpm/low speed. It wasn't stalling but it chugged forward quite hard. It wouldnt drive slowly at a steady pace. And when i touched the pedal it took off....

• Also congratulations from me too on your completion and it's outcome, I can't wait to feel the difference in my Rabbit when I put the new engine in, probably won't have the boost you have though. But I'm gonna keep reading and playing.  Good luck with it and I hope it stays together for a long time

• Thanks Rabbit TD

  how much pedal are you giving it while its chugging/lurching??? you don't want to do too much of that (putting some good stress on the internals)... if it idles ok it should be fine.  if the low end torque wasn't there, i would suspect you need a bit more low end fueling, or adjustment of the governor.
  
  the extra power that your experiencing is due in part to the 1.9 head flowing way better than the 1.6 head.   :wink: i'm real happy for you man!

• RIGHT ON ED!!!!
  that's great news! glad you are boosting and having fun... :twisted:

  I think the big difference is also the porting and polishing of the intake, head and exhaust mani.
  
  when it does the lurching it's just rolling down a hill... and i'll be giving it like a very very minimal amount of diesel... very slight. no pedal = fine, lots of pedal = takes OFF, just enough to cruise above idle rpm on a downward sloe = lurch lurch lurch.
  
  It still stalls without the cold start OUT unless it's completely up to temp.
  it starts great though with the start out or in but without it out it will stall immediately after i stop cranking.  -  THAT makes me think it's a lack of fueling thing... OR could the pump be an entire tooth too retarded; because i pushed the pump as far as i could towards the head when i tried to fix the rough idle which you guys very accurately determined to be very retarded timing. I think i should try turning the fuel screw in just a smidge perhaps.

• I guess i can change my signature now  
• #193 by Smokey Eddy on 01 Feb, 2009 19:28
• Got the down pipe done this afternoon.
  Yes, i wore slippers.
  
  had to practice welding the cast. It was a fussy bastard!
  
  
  
  
  
  Now to sand blast, wire wheel, buff and paint it!
  Wootsauce.

  my buddies 1.6TD passat was doing this from too much advance - it was injecting and starting to fire so early that it would stall.... worked it out because if would work the the cold start IN.
