Track conditions play a big part also, as does altitude. These two raceways are close, but not even. One is at 480 feet, the other is at nearly sea level - not even, but close enough for govt work.
I'm assuming the V was rolling on street tires, that's even more amazing. Not a bad time at all, considering its weight, power and creature comforts. Throw some slicks on it and a top driver and low 12's just could be around the corner.
