• gas porting pistons? by VW Smokr on 16 Apr, 2010 13:15
• Is gas porting the pistons to increase ring sealing a good practice in our VW diesels, or is it just for racers at high RPMs?

• would help for a bit, but  the porting would fill up with carbon really fast.
  
  even on a gas car, its really only a race thing, where you rebuild(and clean out the ports) often.

  Cool. Then I'm just leaving it to the racers! One less thing to sweat. Really couldn't see how it was going to be of much benefit when the engine will rarely see much work over 4,000rpm.. Sucks too much fuel to operate @ higher RPM range.
  
  Thanks for your reply.
