Great car, congrats on a new record.
You forgot a couple of things though. Less weight, 15% more power, racing tyres, and a Formula 1 driver equals more speed.
But spend $20K extra on an N in weight reduction, give it an additional 30kw, and a set of slicks and I am sure the N would be close... Power to weight ratio has never been the N's strong point.
If I remember correctly, „Sport Auto“ did their lap in 8:20 with the stock car (without traffic).I’ve seen our car around the 8 minute time with traffic ( and not going for a lap record)
