...and who has the exhaust thrust trace data to put up on the next NHRA show?
It doesn't pass, sorry. Most of the fuel that goes through those engines are
simply to cool them. The pipes are just blow torches and are not efficient
thrusters.

The exhaust of a top fuel dragster put's out enough thrust to qualify it

1,100 lb of thrust the engine weighs about 500 lbs and burns about 36
gallons of fuel in 6 seconds so it could actually fly..
Albeit maybe 50 ft. lol

Measuring the power output of a top fuel engine directly is not always
feasible. Certain models use a torque sensor incorporated as part of the
RacePak data system. Dynamometers that can measure the output of a Top
Fuel engine exist; however, the main limitation is that a Top Fuel
engine cannot be run at its maximum power output for more than 10
seconds without overheating or possibly destroying itself explosively.
Making such high power levels from such relatively limited displacement
is a result of using very high boost levels and running at extremely
high RPMs; both of these stress the internal components to a high
degree, meaning that the peak power can only safely be achieved for
brief periods of time, and even then only by intentionally sacrificing
components. The engine power output can also be calculated based upon
the car's weight and its performance. The calculated power output of
these engines is most likely somewhere between 6,340 and 7,460 kW (8,500
and 10,000 hp),[8] which is about twice as powerful as the engines
installed on some modern diesel locomotives, and approaches the power
output of the largest aviation turboprop engine ever built, the 12,000
hp Soviet Kuznetsov NK-12 engine, with a torque output of approximately
8,100 newton metres (6,000 lbf·ft) and a brake mean effective pressure
of 8.0–10.0 MPa (1,160–1,450 psi). Of course, both locomotive diesel
and aviation turboprop engines are designed to produce these power
levels continuously for hundreds of hours without failure; one could
increase the power output of either one by many times if you were
willing to limit power output to 10 seconds or less.
For the purposes of comparison, a 2009 SSC Ultimate Aero TT, the world's
third most powerful production automobile, produces 960 kW (1,287 hp) of
power and 1,508 N·m (1,112 lbf·ft) of torque.

Nope.. I have a test and instrumentation group and most of what they do is
