200 Lb. ramjet?

[Chadly33]

Not being one for doing the maths on jet engines, most of my valveless engines are built first measured later. I was wondering if you guys on the ramjet forum would help out with a 200 pound ramjet design capable of running off of my valveless engine intake? I would like the thrust to be at static if at all possible to boost the power on the jet kart. any help will be much appreciated! an extra 200 pounds of thrust kicking in whenever you hit a switch would be great for straight line runs!
