[Vwdiesel] Up my boost?

[lbaird119 at aol.com]

Increase what exactly?  Mileage?  EGT? Boost?  Cooling? Boost range?
  Gotta figure out where you want to be when you get there before you start on the trip.  :-)  You could go with modifying what you have, which might well do what you want.  You'd want to mod the wastegate either by changing the spring or with a bleed-off "controller" to allow more boost.  Then you need to modify the blow-off valve on the intake side.  If you don't have 2 1/2 to 3 inch exhaust already, you'll want to start there.  It will give better response and lower EGT.

  If that's not enough for you then look for a VNT turbo to put on it but there may be major fitment issues since the VW ones come with the exhaust manifold as part of the turbine housing.  Then you consult Andrew Libby's modifications for making one work properly, with mechanical control.

  Intercoolers are everywhere.  Where to put it and plumbing it in are the hard parts!

Any idea where to look for parts or ways to increase

  You're looking for what everybody wants, more boost over the whole rpm range.  Problem is:  A "smaller" turbo, that gives good low end/quick boost, tops out and restricts flow at higher rpm.  Likewise, a large one, great for top end and even no-waste-gate-needed applications, have nearly no boost until mid rpm.  Thus comes in the multi turbo setups or VNT turbochargers.
 
  Depending on the turbo, you start adding heat from the compressing (or mostly the friction of attempting to compress) of the intake air.  The stock KKK/Garrett turbos start producing enough heat that an intercooler is worth it, somewhere around 6-7 psi. I believe it's over 300F @ a bit under 60F ambient.  Every degree you take off the intake side, seems to come off, 1:1 from the exhaust side.  Not sure just what the boost vs non-boost drop is.  The point is to cool it down so that you can then add more fuel, to bring it back up, gain power, and still run within save operating limits.

I was wondering whats needed to continuously run higher boost, not just on
eavy throttle? I have a high mount k03 for clearance, need to make it a
ybrid turbo?
