Just left the dyno after installing the first Danville Performance 72MM billet VVT!!! Mark Broviak definetly knows how to build a turbo! My dyno numbers don't give the turbo justice considering I'm stock bottomend and only 45 over injectors single pumped. I made 634hp with no tuning adjustments. I make more power quicker and stubstain it longer on the big end!! Should make the 11.90 class for sure. I can't want to run at the track!!
