I flew on a 737-400 this morning and I noticed how quickly the aircraft accelerated and it got me thinking.What passenger aircraft has the best power(thrust) to weight ratio?In other words if we had to line them up on a huge drag strip what aircraft would accelerate the fastest with similar loads over a given distance?I have a feeling the 747 SP would be right up there but I'm not sure...any ideas?

The daily UA 744's to MEL from SYD are said to have VERY short take-off runs.
I'm not sure about pax planes but some G-V's have big engines. 29 360lbs of thrust on a 30m (98 feet) plane seems like alot to me.
I believe that Korean Air 773s have the highest power to weight ratios, because they are equipped with the PW4098.
Korean Air was the only airline to order the PW4098 due to the mishap that PW had with the engine and as a result, they are the only airline to operate the engine. I think that they've even got better power to weight ratios than the 772LR or the 77W.

No airliners, but Eurofighter and F-22 raptor are certainly among the best airplanes in terms of thrust to weight ratio altogether.
On www.flightlevel350.com there is a cool video taken on a Varig MD11 flying from CDG to AMS. If I counted correctly, it took around 18seconds to take off. Try to watch it, it is really cool. I can confirm that empty Cargo MD11s taking off from CGN are real rockets...
