1/4 mile on brand new 295/50 street tires and just basic cement. This is STILL being hampered by severe traction issues during launch efforts. So so ET, but decent mile an hour on the big end. Need some slicks and a sticky track to really hook this thing up, but at least I can get some readings now, as all it would do before is just blow the tires off well into 3rd gear skating all over the place.
