Air Intake Pics Wanted

I don't think that it spreads when full open, but I lost half of my rate of climb and 5-10 MPH at cruise. I will not go that route. The Snap Vents allow the air exit the cockpit without building up pressure and stopping the air flow. The fresh air can't get in if it can't get out, regardless of how many intakes there are.

Mine is 40 numbers after yours so they must have changed the ducting later in the production run. I noticed the lifting and spreading of the canopy at the rear corners and would prefer to keep it latched. Do you know if it does the same thing if fully opened? I haven't tried that yet (new owner).

6505Q. I have no air intakes on my wings. I did the canopy unlatched for airflow, but lost climb and cruise airspeed. It was noisy and tended to spread the canopy, making it harder to latch. I do not recommend the unlatched canopy.

just curious, what is your serial number? It seems as if the later models had an auxiliary intake on the wing(s) with separate ducting. I've found that if I don't latch the rear of the canopy the airflow is markedly increased (but keep below the 100 mph "open" limitation).

From the firewall. The side vents are for the salesman to sell airplanes, not for pilot comfort. Almost all the air comes from the firewall and blows directly on your lap. At 10.5 MPH, the cockpit air is being rapidly replaced. The Snap Vents will also pull hot air into the cockpit in the winter.

Thanks, I saw that information in the general section. Do the supply tubes for your side vents connect to the mixer box on the firewall that is fed from the nose scat tube or from a separate intake on the wing?
