i'd have to say some of the wildest, hairiest sprint car action i have seen on dirt were some of the world of outlaw shows at the syracuse mile years ago. the speeds really picked up in the middle to late 80's. sammy swindell ntr low 25 second bracket avg approx 150 mph pushing a buck eighty down the backstretch. those guys were off the hook. for pavement, it would be the 1995 sammy sessions memorial at winchester, when kalitta & fillip drove underneath a barrel-rolling jason mccord at the checker flag. awesome race.
