Camden Murphy pinned the throttle of a 12,000-pound monster truck down the back straight at Indianapolis Motor Speedway and didn’t lift until the speedometer read 103 mph. That’s a new world speed record for a monster truck, set during a break in Indy qualifying on a track that has seen plenty of speed — but never quite like this.
The truck, called “Power Rush,” was purpose-built for the attempt. Twelve feet tall, twelve feet wide, and packing a claimed 1,500 horsepower, it’s less a vehicle and more a rolling physics experiment. The balloon tires were shaved down for pavement, stripping away the knobby tread designed for dirt arenas where these machines usually operate.
Everything about this truck was optimized for one thing: sustained straight-line speed on a surface it was never meant to touch.
Murphy, known in the Monster Jam world as “Monster Jam Cam,” isn’t some sideshow act. He’s been driving with Monster Jam since 2017, and he’s raced on Indy’s road course in the NASCAR Xfinity Series. The man has seen 200 mph down that same stretch of asphalt.
He still called this the most exciting thing he’s ever done in his career. That tells you something about the violence of the experience.
The previous record was 101.84 mph, set by Joe Sylvester in Norwalk, Ohio, in 2022. That number has been inching upward for over a decade, which makes sense when you consider what’s being asked of these machines. A monster truck is designed for short, explosive bursts — hit the gas, launch off a ramp, land without breaking everything.
Holding wide-open throttle for the length of Indy’s back straight is an entirely different engineering challenge. Durability becomes the problem, not power.
One spectator in the infield, standing near a Blackhawk helicopter on display, captured it perfectly: he’d never heard a monster truck engine howl that loud for that long without detonating. The sound alone must have been something unholy.
There’s a temptation to dismiss 103 mph as pedestrian at a place where open-wheel cars routinely crack 230. But context is everything. This is a machine that weighs six tons, sits on tires taller than most adults, and has the aerodynamic profile of a garden shed.
Drag increases with the square of velocity. Getting something shaped like Power Rush past 100 mph requires brute-forcing the laws of physics in a way that no Indy car ever has to.
Monster Jam staged this during Indy qualifying weekend, which is smart promotional calculus. You’ve got tens of thousands of speed-obsessed fans already in the seats, and you hand them something they’ve never seen before. The crossover works because the audience already understands what speed costs at this track.
They can feel the absurdity of a monster truck doing triple digits on sacred ground.
Murphy’s record will fall eventually. Someone will find another 50 horsepower, shave the tires a little more, maybe find a longer straight. The increments will stay small because the engineering ceiling is real — these trucks were never designed for this, and every additional mile per hour is a negotiation with structural failure.
But for now, 103 mph in a 12,000-pound truck on the Indianapolis Motor Speedway back straight belongs to Camden Murphy. It’s the kind of record that exists purely because someone looked at a monster truck and asked the dumbest possible question: how fast can this thing actually go? The answer, it turns out, is faster than most people would ever want to find out from behind that wheel.
