N/A might do that in the 1/8th mile. I've seen giant money turbo/nitrous fours run high 6s in the quarter... but nothing N/A could do that. It would be the monster world record.
We have a few friends that have grudge match races for that event. I may make it out there on the bike
The pictures of the car and motor are in the track thread I started last weekend. There was no turbo or supercharger and I didn't see any N2O hardware. There were a couple cars like it and they were all in the 6's. that's just the only one I seen with the 4cyl.
