This is Bob Vandergriff's UPS dragster being started in the pits, right before his loss to Tony Schumacher in Sonoma 2007

  • Doesn't it go onto the second fuel pump (High side) at 1:51 when the revs drop and more fuel comes out of the headers and the guy who started the motor steps back?

  • ..

    As mentioned, they were only running one pump.

    Same as only running one mag. They do not need, or use both for that.

    ..

  • they now can deliver packages faster and louder!!!

  • New vechicles for UPS:D

  • HAHA. Right on brother.

  • Most of what you see is the vapor of still expanding nitro exhaust. Nitro burns so long that it's still expanding as it passes out the exhaust path . They're tuned specifically for each run. That tuning normally means packing as much air and fuel into the cylinders as the track will handle. It's a delicate balance between tremendous power output and a hydraulic'd, blown up motor.

  • it keeps the engne cool

  • No they aint.

    some of them start em up on methanol and the rest fire them up at 2 pumps, and then they have a shutoff valve, they can ajust the return fuel when they are making burnout and just starting it up in the pitts ;)
