I have not seen smart drivers conrod after last weekend, so I cannot comment on that, but what I can say is, that I was not very impressed with the power it made.
I'm used to fast modifieds like Murnan's and my own ones and the D5 felt rather average on the track.
I drove smarty's car in the main (because the whimp had a headache
) and wasn't impressed at all.
We were both thinking about replacing the 6.5 mm carb with a 5.5mm Nova Rossi carb.
I'm going to brak in my D3 soon and I will watch the rod closely and report.
