Not bad at all!!! I tried one earlier today. I'm not sure it's even worth posting, the video is such bad quality... plus it was more like 15-60... and I picked the worst road ever to do it on, but it was a spur of the moment thing. It was really uneven and I got ZERO traction.
Here it is anyway, screw it lol.

I'll see if I can do something better this weekend. This thing should be around 4 or the high 3 seconds if I can ever get a good launch and not have my tires break loose.
