Some of you may remember the rocket bike powered by roofing tar built by Tim Pickens some months back. He was experimenting with the engine and kept building more powerful versions, getting up to 200 pounds of thrust which worked well enough on the bike but he had more ambitious plans, like putting a much bigger version in a pickup truck.
Well, Tim has his truck now, a 2003 Chevy SS with a rocket engine producing 2750 lbs of thrust. I guess when you get started on a project like this, you just keep going until something blows up, then you scale back, re-engineer and get going again. As far as I know, nothing has blown up yet so we’ll see what Tim builds next.
