Turbocharger Pit Bike (Test Run)

So It does run and does build some boost but it wants to die out when it at Wide Opened Throttle. So I will need to get a Fuel Pump and a Fuel Pressure Regulator on it. What is happening is once it's under boost the air pressure wants to push the fuel back into the Main Jet. Although I do have the Fuel Tank pressurized and the Carburetor pressurized as well but it's building more boost then the fuel tank is ale to push out.

Turbocharger that I used is this one
