J&B Weld Holley Carburetor Mods? | More Performance Carburetor Tuning tricks | How to Gain More CFM!
• Holley 600 Carburetor | Choke Horn De... Joseph's video
• Project XMC: Flow Bench Testing Gains... XMC Last Video
following up on our XMC Carburetor flow testing project we are doing in collaboration with @josephnowak
we are filling our 600 cfm holley carburetor full of J&B Weld Epoxy in pursuit of performance! how so? well by redirecting the airflow going into the carburetor we are hoping to improve booster signal and velocity and overall cfm flowing through it. and we are redirecting the airflow by putting J&B weld into all the dead areas of the carburetor smoothing airflow giving the top of the carburetor a nice radius entry.
now in order to do this we needed to figure out a work around with the accelerator pump discharge nozzle....since it is now permanently impeded into the carburetor now.
well I figured that the main purpose of the discharge nozzle is to restrict fuel flow through an orifice.....so instead of adjusting the orifice of the nozzle of the squirter I drilled and tapped the circuit of the accelerator pump itself to accept an air-bleed jet so I can adjust fuel flow of the circuit itself! .....which I believe will work in the same way?
lots more work to do!
