Hello Robert,
As I introduced myself in and asked D.V. a couple of questions in his Powerquad thread, I would love to see a write up on cylinder head flow on the VW TDI engine.
Despite the small displacement, people are achieving the kind of specific power that rivals 900 HP Cummins and Powerstroke engines in a street-able package and able to return 40+ MPG in normal driving. However, head-work and cams are still relatively uncharted territory for but a few. I myself have done engine mods to the TDI and
developed a performance cam for it.
Best regards,
Dave
