I thought they were using rocket motors without the parachute ejection charge. Just all 'go' power in the motor.

The car went 85mph in 1.7 sec in that video with a small 13lb thrust composite rocket engine....2 days prior I ran a 23lb engine for 1.4 seconds....thing was ballistic but I didn't get a start on my GNSS some didn't get a read....got lots of new engines I will be testing in the near future...stay tuned!

Building my own engines now...after initial cost for the housing, the reloads are much cheaper...have some runs coming...and several that Thumbs hasn't posted
...but none with this new engine combo....also, I have yet to wreck the car with the Camaro body or custom Factory Works chassis....dozens of runs so far

Dude do they roll over after 100? 114? Just speculating.

So the end of run tumbling... it's like you need a ramp at the end and some James Bond style deployable wings. Just sayin'.

I wonder if it's the duty cycle or refresh rate of the testers ? Maybe they just don't test frequently enough for that kind of acceleration?

The "braking zone" looks pretty brutal. Is the chassis holding up well?
