Anybody notice that those are homemade jet engines?  Three semitruck
turbochargers and a bunch of ducting!
And only 190 Lb thrust from three engines that weigh how much 600Lb pretty
poor thrust to weight ratio considering that a small turbine engine used on
an aircraft weighs a few hundered pounds and puts out over a thousand
pounds of thrust.  Or even better for this car how about a FJX-2  700Lb
thrust 100Lb weight think of the possiblilities.

On the issue of fuel mileage if it burns fuel like other turbojets it is
probably burning something like .6Lb (at the minimum) per HP per Hr so
thats 21Gals *8Lbs per gallon for Jet A divided by 190Lb thrust divided by
.6Lbs gives us a running time of about 1.5 Hrs  or at 85 mph only 127 miles
(6 mpg!), but oh wait that stop and go traffic must be a pain with that
fuel burn at idle!  And I don't think the people behind you will like
seeing thier paint burning off thier hoods as you sit at a light.
