What is "STH"?

Sorry,I am not very clear about reed valve. Does the valve has two doors?
I remember the common valve only has one door that can be oped and close.

Why don't use a reed valve at the end of outlet of the combustion? cloesed combustion has more efficiency though it mat be hard to control?

Do you only use only one chamber?

The origional design had one at each end but the valve on the exhaust end keeps burning up so I removed it and decided to run without it.

Yes, only one combustion chamber.

I can understand your situation because the condition is limited.
If you do as you said. It would be a little like the impulsion propulsion that somebody has tried before.

If the combustion hasn't finished ,Can you think the turbine can bear?

New excitement for me!!!!!!!!!!!!!!!!!
I'm now the proud owner of two 14" turbos and six large and substantial reed valves "twin-turbine quad reed ram-jet" equiped go-cart here I come!!!!

Dear DFINITLYDISTRUBD:

I suggest firstly you fixed the engine with a shelf. after adjust it ,it can work normally, You let it drive your cart.

I'm assuming that you mean to run a richer fuel mix so a portion of the unburned fuel air mix reaches the nozzel and burns there?
should be OK.

If you do as you said

Not quite sure what you mean. This engine is one of two already built and is used for recreation almost dailly.

I'm assuming you mean to put it on a "test bench", tune it, then run it like he** so if it's gonna blow it does so without taking me with it?

I recognize that in the new jet,the gas after the turbine still has more energy than the current jet, so the the shape of the general pipe might be different from the drawing i drew before In some case.

i modify the drawing for you reference.
