i have on both race motors and pump gas Hi PO (above 600 HP) street motors, every time I increased the air and fuel flow the HP on the engine dyno went up, from 30 to 65 HP gain depending on the motor and heads, At the 1/4 mile tracks the ET and MPH got better also, going from a single four barrel carb and intake to a six pack and later to a tunnel ram and two 850 CFM 4150 carbs with no other changes went quicker and faster, .2 tenths on the pump gas six pack motors and more on the race gas bracket motors with dual dominator carbs up scope wrench
What are your plans on the intake and carb size and brand? work shruggy
