F-35 Engine for a car: 1/4 mile fastest?

If you feel you absolutely must talk about cars, morality, or anything else not related to the F-16, do it here.

Hi Everyone

As a fan of military jets and just the pure power from those engines I have to admit that after going to the NHRA drag races in July I was a little surprised to learn that the 1/4 mile speeds were faster in non jet cars (Top Fuel Drag cars). Something like 4 seconds and 350mph or faster. A Jet car called the Fireforce 5 did a 1/4 mile in 5 seconds at 310 mph- Fast but not faster than Top Fuel Drag cars. It is using a Pratt & Whitney J60 engine from a Sikorsky Skycrane helicopter. Would Jet cars be faster than the drag racing cars if they used modern military engines (even an F-16 engine) or would it not matter much because of other reasons?

Thanks.

It's all about the launch at the starting line. Jet cars take longer to get going from the dead start.

Static thrust of a jet is rather low but picks up when dynamic thrust builds with speed.
Not good for sprinting affairs.

I think if somebody calculated how much force was being applied by the tires at the contact area it would be obvious why the 6000 hp motor driving wheels wins. (Turn your turbojet into a turboshaft and use it to drive wheels and you'd get the same effect.)

It will be quite a long time before we ever observe a surplus F-35 engine sold off, most likely NEVER!
