Not sure if everyone has seen this before, but today was the first time for me, so I figure I'd post it for you engine nuts. Absolutely awesome and the attention to detail is amazing. Obviously there's no ignition or combustion and it runs off of compressed air, but still awesome nonetheless. Cheers!
