    Ok, so while on line for this ride at Hershey Park, one gets to read:


    • "12.0 ton coaster weight"
    • "2.5MW" electric launch
    About 208KW / Ton

    Tesla PD's
    • 2.3 ton
    • 0.45MW (w/"L")
    About 195Kw / Ton
    • 0-60, in 2.8-3.0 seconds

    Dig deeper, and you find the coaster gives an equivalent 5MW launch, aided by nitrogen gas and oil compression ( Top tech roller coasters | Network World ).

    "When we designed Storm Runner, we were looking to design a linear induction motor system, but we did the calculations and we were going to turn the lights on and off in Hersheypark," Bachmann says. "What we ended up doing is knocking the power consumption down by half by using nitrogen gas and oil to launch the 12-ton trains."

    Pretty neat, that weight/power between the car and the coaster aren't that far apart. We chopped a second, from the P85 and 85D. All we need for another, is some nitrogen, oil and traction :biggrin:.

    That's 195kW / ton when it hits peak at 36 MPH otherwise the P85D would accelerate to 60 much faster if it could dump it's full power at 0 RPMs.


    Where are you getting 195kW?

    414KW / (4936 / 2000) = 168 kW / ton.

    Doing some quick math leads to 480 kW -- presumably referring the last tick on the power consumption meter on the instrument cluster.

    Ahh. I could see how someone might come to that conclusion looking at the dial. Of course it's too compressed with a 100KW of range covering just a few pixels.
