There's so much debate about boosting nitro engines so I wanted to get your guys opinion on the subject. To me it doesn't seem possible to get a pressure increase when the intake port closes before the exhaust. I've watched RBI's video explaining how the sonic pulse works but does it work to the extent they say it does? Other than RBI's video on the sonic pulse I can't seem to find any other info on it. I'm just guessing here but I'm thinking the sonic pulse would only be able to push a small portion of air/fuel back into the cylinder. Lets just say it has enough force to push 2 cubic centimeters of air at 2lbs per square inch. If the SC is pushing is pushing more than that the sonic pulse would be met with a higher opposing force so wouldn't it push back less pressure or less cfm? Or would it still equalize to push the pressure back to equal the same cfm as a normally aspirated engine? I'm thinking the latter. I'm curious how it would work if you installed a small blow off valve inside the header. Adjusted to block or restrict the lower pressure of the SC from exiting the cylinder but open to allow the higher pressure of the exhaust to escape. The sonic pulse would be eliminated but the SC would pack more air into the motor. Now that it would be truly boosted would the increased pressure in the carb allow fuel to enter. I think not. I think you'd have to have an electric fuel pump. The dual hose set up they have doesn't make sense to me. I think it only works because the SC isn't building boost because of the open exhaust port. With my BOV theory the pressure in the carb would be a lot higher than the pressure in the muffler. Attaching the fuel pressure line to the supercharger just puts the same amount of pressure on both sides of the fuel flow. Perhaps more on the carb intake side because of the larger air space it's able to pack more cfm. If the pressure in the muffler is less than the pressure in the carb it will flow out the exhaust tube. My brain is getting too hot!! Lol what are your thoughts?
