System Fabrication: Fuel Proof Resin Possible material for velocity stacks: - Product #670 Vinyl-Ester Resin Fuel-Proof 6-months testing 300°-400° Temperature

System Fabrication: Velocity Stacks Machined aluminum velocity stack mold Dimensions –1.35 inch diameter –0.5 inch bell –7.5 inch long 11/14/2015 Vanderbilt Motorsports Intake and Exhaust Project6

Velocity Stack Design: Loss Coefficient for Bell Curve Rounded Entrance To minimize K, loss coefficient at the bell entrance –R/D=0.5/1.35=0.371 –According to table in Applied Fluid Dynamics Handbook by Blevins, K is between
