Yes.
formula is.
pounds of force to the tire now = (horsepower now x 375) / MPH now.
Not factoring for aero or rolling resistance.

900 ft-lbs of torque sounds like a big number to some, in context it is not. I can do that with my hands and a sturdy length of pipe.
I doubt any human could generate even just 5 HP, most not even 2 HP.
Horsepower is what puts thousands of pounds of force to the tires. High horsepower launches 10,000 pound monster trucks over many cars.
