Well actually a big piece of the puzzle that's missing is proper bodywork. It looks like Batman's Tumbler from behind, and so this is going to be the major cue. However, it's difficult finding anyone with the skills to pull off a decent look and customised to the vehicle itself. I might have to put a feeler out to Pinewood Studios or something! It will have a 'hump' where the cabin is, because of the height of the fuel tank - but if the thing is elongated and given a snout/overhang, there should be space enough to make the thing look good, rather than awkward and bulbous atop.

On the melting bumper question - it's a good inch or so below the actual exit aperture, so is normally fine. However, on full throttle the nozzle does glow bright-red hot even in daylight, which if the vehicle was static would melt the bumper a bit with radiant heat alone - but if driven there's enough airflow to prevent this.

Hey thanks buddy. Indeed not flat-out at all - the grass was freshly cut, & at full throttle it sucks to much of it up & blocks the screen (then flames out). It was prob 1/2 throttle at most, anywhere in that video. That's Wren's flagship engine - about £2500 in my day, these days £1800.

What 10kg of thrust 'looks' like...watch to end!

For those interested, that black cap/nose thing is its starter motor. It'll spin the engine up to about 25,000/29,000rpm - whereafter the engine itself takes fully over ('fuel ramp'). That little glow-plug looking thing is exactly that, and has its own fuel supply - it vaporises the fuel for initial start-up. The fuel pipe going into the actual purple shroud is the main fuel supply that kicks in during fuel-ramp. It's all controlled by two main valves, which are in turn controlled by an ECU - called a FADEC - Full Authority Digital Engine Control. The latest Wren and Jetcat engines have all of this internalised - making for only one fuel supply line needed, a fully internal glow-plug, fully internal valves, fully internal EGT sensor, and brushless fuel pump and starter motor.
