performance question

In my opinion, the best modification you can make to your Scirocco is a lightened flywheel.  It is cheap, easy, no tuning is required, and there are NO downsides.  Until you drive a 'roc with one, you wouldn't believe the difference.

  Before changing your fuel system, might I suggest getting a cam first?

  CIS Lambda (what your 81 has stock) is typically known good to around 150hp or so....thats why I don't think you should be looking at changing fuel just yet...I doubt its the real problem here, unless you are seeing it run lean at high RPM with a air/fuel guage or on a dyno with a exhaust gas analyizer.

  The stock VW cams are tuned for low end torque and driveability, you will see that you really don't have much power in the high rpms and an unwillingness to rev quickly.

  Getting a more agressive cam should give you a bump in power in the higher rpms, better revability, with a loss in bottom end torque.

  Just recently, I jammed a Kent 278 cam into my completely stock JH engine.  Driveability was slightly affected, and there was a decrease in bottom end torque (this is all from the butt dyno, personal impressions).  However, the car has a nice jump in power from 3-4k and pulls cleanly right past red line, no problems with good high RPM power.  No changes to fuel system, timing, igntion, nothing, just a cam.  The motor would choke out around 5k rpm before and had little power up there anyway before the cam.
