Only 1/8 mile tracks down here but it should be in the high 9's in the 1/4 and mid to high 130's mph. It has a roll bar in it but they have never even looked at it at the tracks I race at. The best it has run in the 1/8 is 1.34 60ft., 6.34@ 109 mph.so far. It carries the front tires about 20-24 in. for about 40ft. with drag radials and caltrak bars.2013-07-02 20.12.28.jpgIt is a pump gas small block with mufflers also.
