I have an important question. Is there alcohol involved in building or running these things?

Actually we poured more alcohol into the engine today than we have poured into ourselves while building it, my friends aren´t exactly heavy drinkers and we don´t want to risk a failure by forgetting to tighten a hose clamp while being piss drunk...
Here is todays test, EGT with afterburner and without water injection 750°C and it dropped to 710°C with 1L/min water injected. Thrust reading somewhere around 50kg, the kick stood in an upslope so it jammed on the rollers.
The thrust reading in the video is perhaps not by the book.. ;D
No rev figures unfortunately, the laser transmitter didn´t allign with the hole in the nut. We ran the engine at 2.4bar P2 and won´t go any higher for safetys sake.

I don't think the heat shield is THICK enough... Did you SEE that A/B pipe!!!! Could cook eggs faster than a microwave . Congrats!!! Ernie

During static runs the heat shield is far from good, but once the cold air starts to blow between the AB and shield the surface temp should be ok.

Yup, next time we run it is to get her heated up for the race. Keep your fingers crossed guys that the engine holds together and gives the kick a decent speed, preferably around 150km/h.

Thanks guys! We said to each other on the way home that we must have been laughing constantly the entire weekend, I cannot remember the last time I had this much fun. Finishing the race was like topping on the cake, now we have one year to improve the kick and see how fast she can go with straight runners and full throttle.
