Drilled a 2 inch bulkhead fitting in stock air box for additional two inch snorkel. One snorkel alone was restricting the flow . Using shop vac 2 inch vacuum hoses for bends. Still need to clean up clamps. With tire pressure at 25 psi. GPS reads 42 mph.

I have a question for you. How did you determine air flow was restricted? 2 inch vac hose should flow as much as or close to 2 inch pvc. I have done the same but ran the hose all the way to the underside of the roof. My findings are it has more air flow than the stock set up. Mine was running. leaner is how this was determined

Leaner would indicate too much air, not enough fuel. That would mean your snorkel was flowing more than enough air.

Placing my hand over the inlet ,has some suction. With another two inch. Now has less suction and acceleration is much noticeable. Without vacuum gauges i will never know. The actual difference
