  Janne´s sylinderhead is full race head without any compromise   :twisted:

• wooowwwwww
  That's amazing. So much work! You guys must have your own machine shop!!! what is the groove in the middle for?

• it´s for air,conduct to pre camber.it´s very important and shape should be smooth.
  
  my own sylinder head is little different shape as usually  :twisted:

• Hello guys!
  
  Sorry for not updating for a while - I've been extremely busy with work and school lately...
  
  Aki: Incredible work as usual! We'll have fun when I come over!
  And I will want to drool on your own project's special parts too!
  
  I HAVE been working on the Jetta anyway!
  The body reinforcements are almost complete, and tomorrow I will take all removable body parts to the paint shop.
  I've been sourcing some  missing parts too.
  Too bad my schedule has bent this far though..
  Now it seems the Jetta will be driveable no sooner than April.
  On the other hand, a big project like this is something where cutting corners isn't a wise choice so I'll just have to be patient and keep on working.
  
  Thanks for all the interest to all you good people!
  I will post some photos of my own in a couple of days!

  There are some guys getting better combustion with "V" grooves on their pistions.... sharp edges.

• Those are gassers though.
  
  I think jimfoo did this as well for his Rover but he didnt have any before measurements to compair.

• did you break a timing belt?(valve kisses?)
• #175 by rallydiesel on 16 Feb, 2009 19:13
• No, I think he's running oversized valves.
• #176 by TurboJ on 17 Feb, 2009 02:28
• He most certainly is  
• #177 by Smokey Eddy on 17 Feb, 2009 02:37
• Are you going to do ceramic coating?
  
  This is probably the most intensive build i've seen yet. So much bottom end work and alterations. IE. over sized valves! and that is some AGGRESSIVE porting going on
• #178 by TurboJ on 17 Feb, 2009 03:17
• Remember there are two engines talked about here.
  
  The head porting pictures are of my 1.6 engine with AAZ head,
  the pistons are from Aki's twin turbo engine.
  
  As for the ceramic coating, both our engines will have that. (Piston tops, combustion chambers, exhaust ports and manifold, possibly also insides of the pre-cups).
  Now I hope I had bough those uprated con-rods after all.
  The rods are now the only thing that prevent me from going seriously over 200 hp. Well, there's always next time...
• #179 by RabbitJockey on 17 Feb, 2009 14:49
• get custom ones, i am considering it, and i'm not doing half the stuff you are, such as the girdle and ceramic coating,  the rods really seem to be what fails on these motors when they're built, i'm not planning on getting 200hp tho either.
