Hey, you said you have a ramjet. I bought one recently and put it in my truck. I noticed a hissing sound sometimes when accelerating, and asked someone about it and they said that it was the throttle body. It seemed logical because it sounds like it is coming from the front of the engine, but I was curious to see if anyone one else with one of these engines has this sound. Anyways, to my question. Do you have this sound when accelerating? If not, have you done anything different to the engine? What type of air filter do you have on your truck. I will include a picture with the air filter that I have. Thanks.
